Purpose: To investigate the long‐term efficacy and safety of intravitreal brolucizumab (BRZ) injections in patients with typical neovascular age‐related macular degeneration (typical nAMD) and polypoidal choroidal vasculopathy (PCV). Methods: This multicentre retrospective study included 401 eyes of 398 patients with nAMD who received BRZ injection(s), with a follow‐up duration of ≥12 months. Changes in best‐corrected visual acuity (BCVA), retinal fluid evaluation and central subfield thickness (CST) on optical coherence tomography were assessed. The efficacy of BRZ was compared between typical nAMD and PCV groups. Results: Analyses were conducted with 280 eyes of 278 patients with typical nAMD and 121 eyes of 120 patients with PCV (mean age, 71.1 ± 8.6 years). 29 eyes (7.2%) were treatment naïve. The mean follow‐up period was 15.3 ± 2.8 months; the mean number of BRZ injections within 1 year was 4.5 ± 1.7. BCVA was maintained during the follow‐up period, and CST significantly improved from the first injection month and was maintained for 12 months in both the typical nAMD and PCV groups. The dry macula proportion increased from 2.7% at baseline to 56.1% at 1 month and 42.9% at 12 months. Among the 18 eyes that underwent indocyanine green angiography both before and after treatment, 10 (55.6%) showed polyp regression. Overall, the incidence of intraocular inflammation (IOI), retinal vasculitis and occlusive retinal vasculitis was 9.4% (38 eyes), 1.2% (5 eyes) and 0.5% (2 eyes), respectively. IOI occurred from the first to the sixth injections, with an average IOI onset of 28.5 ± 1.4 days. All eyes achieved IOI resolution, although the two eyes with occlusive retinal vasculitis showed a severe visual decline after IOI resolution. Conclusion: Brolucizumab was effective in maintaining BCVA and managing fluid in eyes with nAMD for up to 1 year, exhibiting a high polyp regression rate. However, the not uncommon incidence of IOI and the severe visual decline caused by the rare occlusive retinal vasculitis following BRZ treatment underscore the importance of careful monitoring and timely management.

Objectives Methods Results Conclusions Patients with polypoidal choroidal vasculopathy (PCV) exhibit variability in response to anti‐VEGF therapy. This study aimed to analyse the aqueous humour proteomic profiles of PCV patients and provide preliminary insights for the identification of biomarkers associated with anti‐VEGF drug responsiveness.PCV patients who were treatment‐naïve or untreated for more than 3 months were prospectively recruited from two hospitals in Beijing and Tianjin. Based on the relative changes in central macular thickness (ΔCMT/baseline‐CMT) before and after anti‐VEGF treatment, the PCV patients were divided into a good response (GR) group (≤−25%) and a poor response (PR) group (>−25%). Aqueous humour proteomics was performed by the Data‐independent Acquisition‐Mass Spectrometry (DIA‐MS) method, and differentially expressed proteins (DEPs) analysis between the different PCV groups and the control group was conducted. Key DEPs were selected for preliminary validation in the aqueous humour using the Luminex method retrospectively.A total of 31 PCV patients (31 eyes) were included, 13 in the GR group and 18 in the PR group. A total of 414 DEPs were identified, including 36 significantly upregulated proteins, such as G protein regulatory factor 10 (RGS10), podocin (PODN) and epidermal growth factor (EGF), and 32 downregulated proteins, including RAB11FIP4 (Rab11 family‐interacting protein 4), α‐synuclein (SNCA), haemoglobin subunit δ (HBD) and interleukin 6 (IL6). Compared to the cataract control group (10 eyes), 134 proteins were significantly upregulated, and 72 were downregulated. KEGG pathway enrichment analysis revealed that the GR and PR groups differ in terms of cell communication, and cell signal transduction. Protein–protein interaction analysis revealed interactions between EGF and various DEPs. Validation of aqueous humour proteins using the Luminex method revealed that changes in the levels of EGF were associated with the anti‐VEGF treatment response in PCV patients.PCV patients with good or poor anti‐VEGF responses exhibit distinct aqueous humour proteomic profiles. Aqueous EGF may serve as a biomarker for the ‘precise treatment’ of PCV. [ABSTRACT FROM AUTHOR]

Background/Objectives: Anti-vascular endothelial growth factor (VEGF) therapy is the first-line treatment for neovascular age-related macular degeneration (nvAMD). While proactive and adequate treatment generally leads to better visual outcomes, various factors, including the disease type, ocular findings, lifestyle, and systemic status, affect the visual prognosis in clinical settings. This study aimed to identify the factors that affect the visual prognosis in patients with nvAMD treated with anti-VEGF therapy. Methods: We conducted a multicenter retrospective cohort study at eight tertiary referral centers in Japan, where we reviewed the medical records of patients newly diagnosed with nvAMD between January 2014 and December 2019. These patients had started treatment with either ranibizumab (0.5 mg) or aflibercept (2.0 mg) and were followed for at least 1 year. We evaluated the impact of the disease type, systemic factors, and initial fundus findings on the best-corrected visual acuity (BCVA) at 1 year. Results: This study included 182 patients (129 men, 53 women), with a mean age of 75.0 ± 8.6 years. The disease types were categorized as typical AMD (53%), polypoidal choroidal vasculopathy (PCV) (43%), and retinal angiomatous proliferation (RAP) (4%). Univariate analysis identified age, the baseline logarithm of the minimum angle of resolution BCVA, intraretinal fluid (IRF), pigment epithelial detachment (PED), and subretinal hyperreflective material (SHRM). Multivariate analysis identified the following significant risk factors associated with vision worsening: age, smoking history, diabetes, and the presence of IRF and PED. Conclusions: The presence of IRF, PED, and SHRM at the start of treatment and a history of smoking and diabetes may be associated with a poor visual prognosis in patients with nvAMD.

Background: This study aims to evaluate the two-year outcomes of polypoidal choroidal vasculopathy (PCV) treated with conbercept and to investigate the predictive response factors. Methods: Consecutive patients with PCV who received three-loading intravitreal conbercept, followed by as-needed reinjections, were studied retrospectively. The best corrected visual acuity (BCVA), central retinal thickness (CRT) and polyps were evaluated. Patients who achieved dry maculae in month 6 were categorised into the dry group, or otherwise, into the non-dry group. The predictive factors for a dry macula were evaluated. Results: A total of 25 eyes from 25 patients (17 males; mean age: 62.8 ± 6.4 years) were included. At month 24, the average BCVA increased significantly from 49.9 ± 15.0 letters to 57.2 ± 16.0 letters (p = 0.040); the average CRT decreased significantly from 430.16 ± 166.55 μm to 278.31 ± 157.34 μm (p = 0.00), and 88% of the eyes achieved dry maculae. The number of polyps changed from 55 to 20 (fading rate: 63.6%; p < 0.001). The mean number of intravitreal injections was 8.6 ± 5.4. The dry group (10 eyes, 40%) was more likely to have higher branching vascular network vessel density (BVN VD; p = 0.021), submacular haemorrhages (p = 0.011) but lack polyp-related serous pigmented epithelial detachment (PED) (p = 0.037). Conclusions: Conbercept was effective in eyes with PCV at maintaining functional and anatomical improvement. Baseline characteristics, including BVN VD, the presence of polyps with serous PED and submacular haemorrhage, seemed to be related to the response to conbercept. [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study was to investigate demographic, anatomical, angiographic, and functional parameters in patients suffering from polypoidal choroidal vasculopathy (PCV). Methods: Sixty eyes of 60 patients with a definite diagnosis of treatment-naïve exudative unilateral PCV were evaluated in this retrospective study. Fellow eyes and age-matched healthy subjects were enrolled as comparison. All subjects underwent complete ophthalmic evaluation with multimodal imaging assessment, including spectral-domain optical coherence tomography (OCT) and OCT angiography. Main outcome measures in the comparison analysis were central macular thickness (CMT), subfoveal choroidal thickness (SFCT), and choroidal vascularity index (CVI), whereas outcome measures for correlation analyses were best corrected visual acuity (BCVA), intraretinal fluid and subretinal fluid (SRF) presence, SRF thickness, vascularized pigmented epithelial detachment height, and PCV outer retina to choriocapillaris flow area. Results: CVI was significantly higher in affected and fellow eyes if compared with the healthy ones (p = 0.049; p = 0.003). Subfoveal choroid resulted to be thicker in the diseased eyes when compared with healthy ones (p = 0.002). A negative correlation was assessed between age and SFCT, CMT, and BCVA. In addition, a significant association between male gender and anatomical and functional parameters has been found with male prevalence at baseline in cases. No association between systemic conditions and PCV features was found. Conclusions: Patients with unilateral PCV show choroidal changes in terms of higher values of CVI, also in fellow eyes, that were negatively related with age. In our cohort of patients, males showed the poorest diagnosis with a baseline lower BCVA and higher CMT when compared with females. PCV was not associated with any systemic condition.

Purpose: To investigate the influence of submacular hemorrhage (SMH) at baseline on long-term visual outcomes of patients with typical age-related macular degeneration (tAMD) and polypoidal choroidal vasculopathy (PCV) treated with intravitreal aflibercept (IVA). Methods: In this retrospective study, eyes of treatment-naïve patients with tAMD and PCV who initiated IVA under a treat-and-extend regimen and were followed up for ≥ 5 years were classified into the tAMD-SMH (+), tAMD-SMH (-), PCV-SMH (+), and PCV-SMH (-) groups based on the presence of SMH at baseline. Best-corrected visual acuity (BCVA) changes and macular fibrosis and atrophy incidences were assessed. Results: This study included 127 eyes (127 patients), including 51 with tAMD and 76 with PCV; 18 eyes had SMH at baseline. In the tAMD-SMH (+) group (n = 6), the mean logMAR BCVA significantly deteriorated from 0.59 ± 0.45 at baseline to 0.88 ± 0.47 at the final visit (P = 0.024). No significant BCVA changes were observed in the tAMD-SMH (-) (n = 45), PCV-SMH (+) (n = 12), or PCV-SMH (-) (n = 64) groups (all P > 0.05). The tAMD-SMH (+) group showed a significantly higher incidence of macular fibrosis at the final visit than did the tAMD-SMH (-) group (P = 0.042). There was no influence of baseline SMH on the macular fibrosis incidence in eyes with PCV and the macular atrophy incidence in eyes with tAMD and PCV. Conclusion: The presence of SMH at baseline resulted in poorer long-term visual acuity in eyes with tAMD, even with aflibercept treatment. However, no such influence was observed in eyes with PCV.

Introduction: This study evaluated the cost-effectiveness of anti-vascular endothelial growth factor (VEGF) therapies for subtypes of neovascular age-related macular degeneration (nAMD) from the societal perspective, and for any nAMD from the patient perspective in Japan. Methods: A Markov model was developed to simulate the lifetime transitions of a cohort of patients with nAMD through various health states based on the involvement of nAMD, the treatment status, and decimal best-corrected visual acuity. Ranibizumab biosimilar was compared with aflibercept from the societal perspective regardless of treatment regimen for the analysis of three subtypes (typical nAMD, polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP)). Two analyses from the patient perspective focusing on the treat-and-extend regimens were performed, one with a cap on patients' copayments and one without. Ranibizumab biosimilar was compared with branded ranibizumab, aflibercept, aflibercept as the loading dose switching to ranibizumab biosimilar during maintenance (aflibercept switching to ranibizumab biosimilar), and best supportive care (BSC), for patients with any nAMD. Results: In the subtype analyses, ranibizumab biosimilar when compared with aflibercept resulted in incremental quality-adjusted life years (QALYs) of − 0.015, 0.026, and 0.009, and the incremental costs of Japanese yen (JPY) − 50,447, JPY − 997,243, and JPY − 1,286,570 for typical nAMD, PCV, and RAP, respectively. From the patient perspective, ranibizumab biosimilar had incremental QALYs of 0.015, 0.009, and 0.307, compared with aflibercept, aflibercept switching to ranibizumab biosimilar, and BSC, respectively. The incremental costs for ranibizumab biosimilar over a patient lifetime excluding the cap on copayment were estimated to be JPY − 138,948, JPY − 391,935, JPY − 209,099, and JPY − 6,377,345, compared with branded ranibizumab, aflibercept, aflibercept switching to ranibizumab biosimilar, and BSC, respectively. Conclusions: Ranibizumab biosimilar was demonstrated as a cost-saving option compared to aflibercept across all subtypes of nAMD, irrespective of the perspectives considered. [ABSTRACT FROM AUTHOR]

Background: Pneumococcal disease (PD) is a major cause of morbidity and mortality in young children in Asia and globally. Pneumococcal conjugate vaccines (PCVs) have significantly reduced the burden of PD when included in pediatric national immunization programs (NIPs). This study estimates the clinical and economic burden of PD due to serotypes contained in different PCVs in children aged < 5 years in eight Asian countries/territories. Methods: Based on published data, a cohort-based decision analytic model was used to estimate annual PD cases, deaths, and direct medical costs associated with serotypes contained in PCV10, PCV13, PCV15, and PCV20. Results: PD incidence rates were lower in regions with PCV13 in their NIP than those without. Serotypes contained in higher but not lower valency PCVs resulted in a significant incremental clinical and economic burden, although the difference between PCV13 and PCV15 serotypes was generally small. Moving from PCV13 to PCV20 was estimated to result in greater clinical and economic burden reductions. Conclusions: This study demonstrates the remaining and incremental burden of PD from PCV10 to PCV20 serotypes in young children in selected Asian regions. Extending NIP access to higher-valency PCVs with broader serotype coverage and improving vaccine uptake will help prevent morbidity and deaths and save healthcare costs. [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study was to explore the relationship between choroidal biomarkers and the response to anti-VEGF in PCV eyes. Methods: We conducted a hospital-based retrospective study. We included 54 patients diagnosed with PCV who had received standard 3 monthly anti-VEGF monotherapy and had finished regular follow-ups. Choroidal thickness (CT), three-dimensional choroidal vascularity index (CVI), and the vascular density of choriocapillaris (CCVD) were measured utilizing swept-source optical coherence tomography angiography (SS-OCTA). Effective and poor responders were classified based on the changes in morphologic features. Multivariate linear regression models were performed for the outcomes to determine independent prognostic factors. Receiver operating characteristic (ROC) curves were used to compare the predictive ability of CT and CVI as biomarkers between effective and poor responders. Results: A higher CVI at baseline was the only factor that correlated with the poor response after 3 monthly injections of anti-VEGF (p = 0.038). The greater change of central macular thickness (CMT) was significantly correlated with increased CMT (p = 0.030), decreased CT (p = 0.042), and decreased CVI (p = 0.038) at baseline. Using ROC curves, we found that the CVI value demonstrated superior predictive ability compared to the CT value, with AUC of 0.842 and the best cut-off value of 0.445. Conclusion: A higher three-dimensional CVI using SS-OCTA is a promising biomarker to predict the poor anatomical response to anti-VEGF treatment in PCV patients. [ABSTRACT FROM AUTHOR]

AbstractPurposeMethodsResultsConclusionsTo identify risk factors and effect modifiers associated with intraocular inflammation (IOI) following brolucizumab injection.Our protocol was registered on PROSPERO (CRD42022382645). We searched six electronic databases (PubMed, Scopus, Web of Science, CENTRAL, EMBASE, and Google Scholar) to retrieve all studies that reported the occurrence of IOI following brolucizumab. Data are reported as mean difference with their corresponding 95% confidence intervals. All analyses were conducted per eye, and the risk of bias was assessed using the National Health Institute tool.Our analysis included 3527 eyes of 3469 patients of 33 papers. The mean age of the patients was 74 years (SD = 10.9, Range = 62.3–80.9). There were 1793 male patients (51.7%) and 1719 female patients (49.6%). The average follow-up period was 13.9 months (SD = 9.4). The mean number of injections was 4.5 (SD = 2.9) injections per eye; 1315 (37.3%) eyes had neovascular AMD, 189 (5.4%) had diabetic macular edema, and 129 (3.7%) eyes had polypoidal choroidal vasculopathy. Post-intervention, subretinal fluid, intraretinal fluid, and pigment epithelial detachment were significantly improved (46.5–11.3% of patients, 55.7–11.3% of patients, 24.7–7.1% of patients, respectively) (p < 0.001). Regarding visual acuity, there was an improvement with a mean difference of 0.12 (95% CI = 0.18–0.07, z = 4.38, p < 0.0001, 2064 eyes). The most common reported complication is IOI (n = 196, 6%). IOI was observed more in the elderly (76.3 ± 9.2 years), females (66%), and after the second injection.This systematic review provides valuable insights into risk factors and effect modifiers for IOI associated with brolucizumab treatment, aiding clinicians in optimizing patient care. Future studies should prioritize prospective, long-term investigations to further elucidate the safety profile of brolucizumab and refine its use in the management of retinal and choroidal vascular diseases.

Objectives: To assess the clinical characteristics of patients with macular neovascularization (MNV) with no drusen in the fellow eye, we investigated the incidence of MNV in fellow eyes and the outcomes of intravitreal aflibercept (IVA) monotherapy in MNV eyes of patients with unilateral MNV with a punctate hyperfluorescence spot (PHS) in the fellow eye. Methods: We retrospectively studied 58 treatment-naïve patients with unilateral MNV with no drusen in the fellow eye. Patients were classified into a PHS group (n = 29) or no-PHS group (n = 29) based on the presence of PHS. We evaluated the incidence of MNV in the fellow eye, and the retreatment rate after initiation of three monthly aflibercept injections over one year. Results: Fellow eyes in the PHS group had a thicker choroid (p < 0.05) and higher prevalence of pachychoroid pigment epitheliopathy (PPE) (p < 0.001). MNV eyes in the PHS group had a thicker choroid (p = 0.09). The PHS group had a lower retreatment rate (p < 0.05) and required fewer injections (p < 0.05) than the no-PHS group. MNV developed in one eye in both the PHS and no-PHS groups, and both cases occurred in areas of hypofluorescence on indocyanine green angiography within the PPE area before the onset of MNV. Conclusions: The PHS group frequently exhibited pachychoroid disease characteristics and responded better to IVA monotherapy than the no-PHS group. These groups may represent distinct populations of patients with unilateral MNV with no drusen in the fellow eye. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate short-term outcomes of intravitreal injection of aflibercept 8 mg for neovascular age-related macular degeneration (nAMD). Study design: Retrospective, interventional case series. Methods: We retrospectively studied 35 eyes of 34 consecutive patients with nAMD, assessing best-corrected visual acuity (BCVA), foveal thickness (FT), and central choroidal thickness (CCT) before and 4 weeks after the initial intravitreal dose of aflibercept 8 mg. The rate of achieving a dry macula and the incidence of intraocular inflammation (IOI) at week 4 were also determined. Results: BCVA showed significant improvement, with significant reductions in FT and CCT 4 weeks after the initial injection of aflibercept 8 mg (all P < 0.01), with a dry macula being achieved in 20 eyes (57.1%). However, 3 eyes (8.6%) developed non-infectious IOI associated with retinal vasculitis, an adverse event not reported previously. The IOI in these eyes was relatively mild and treated with a posterior subtenon injection of triamcinolone acetonide with or without betamethasone eye drops, resulting in amelioration of IOI without any visual loss. Conclusions: Intravitreal aflibercept 8 mg appears to be effective for improving visual acuity and ameliorating exudative changes in eyes with nAMD. However, special attention should be given to the potential development of IOI associated with retinal vasculitis. [ABSTRACT FROM AUTHOR]

Abstract To investigate long-term treatment outcomes of polypoidal choroidal vasculopathy (PCV) with classic type leakage and to compare the outcomes with those of PCV without classic type leakage. This retrospective study included 153 patients diagnosed with PCV and treated with anti-vascular endothelial growth factor (VEGF). Patients showing classic type leakage on fluorescein angiography were included in the classic type leakage group (N = 40, 26.1%), and those without classic type leakage were included in the occult group (N = 113, 73.9%). The best-corrected visual acuity (BCVA) at baseline and 24 months, changes in BCVA, incidence of fibrosis, and lesion reactivation after initial loading injections were compared between the two groups. There was no significant difference in the baseline BCVA between the classic type leakage group (mean logarithm of minimal angle of resolution 0.67 ± 0.53[Snellen equivalents = 20/93]) and the occult group (0.55 ± 0.49[20/70])(P = 0.639). In addition, the BCVA at 24 months (0.44 ± 0.53[20/55] vs. 0.38 ± 0.41[20/47])(P = 1.000), changes in BCVA (0.22 ± 0.42 improvement[2.2 lines] vs. 0.16 ± 0.36 improvement[1.6 lines]) (P = 0.366), and lesion reactivation (P = 0.787) did not differ between the two groups. The incidence of fibrosis was higher in the classic type leakage group (37.5%) than in the occult group (14.2%) (P = 0.002). Although the incidence of fibrosis was higher in PCVs with classic type leakage, the overall treatments were not significantly different between PCVs with and without classic type leakage. In addition, substantial visual improvement was noted at 24 months, suggesting that PCVs with classic type leakage can be effectively treated with anti-VEGF therapy.

Abstract Introduction This study evaluated the cost-effectiveness of anti-vascular endothelial growth factor (VEGF) therapies for subtypes of neovascular age-related macular degeneration (nAMD) from the societal perspective, and for any nAMD from the patient perspective in Japan. Methods A Markov model was developed to simulate the lifetime transitions of a cohort of patients with nAMD through various health states based on the involvement of nAMD, the treatment status, and decimal best-corrected visual acuity. Ranibizumab biosimilar was compared with aflibercept from the societal perspective regardless of treatment regimen for the analysis of three subtypes (typical nAMD, polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP)). Two analyses from the patient perspective focusing on the treat-and-extend regimens were performed, one with a cap on patients’ copayments and one without. Ranibizumab biosimilar was compared with branded ranibizumab, aflibercept, aflibercept as the loading dose switching to ranibizumab biosimilar during maintenance (aflibercept switching to ranibizumab biosimilar), and best supportive care (BSC), for patients with any nAMD. Results In the subtype analyses, ranibizumab biosimilar when compared with aflibercept resulted in incremental quality-adjusted life years (QALYs) of − 0.015, 0.026, and 0.009, and the incremental costs of Japanese yen (JPY) − 50,447, JPY − 997,243, and JPY − 1,286,570 for typical nAMD, PCV, and RAP, respectively. From the patient perspective, ranibizumab biosimilar had incremental QALYs of 0.015, 0.009, and 0.307, compared with aflibercept, aflibercept switching to ranibizumab biosimilar, and BSC, respectively. The incremental costs for ranibizumab biosimilar over a patient lifetime excluding the cap on copayment were estimated to be JPY − 138,948, JPY − 391,935, JPY − 209,099, and JPY − 6,377,345, compared with branded ranibizumab, aflibercept, aflibercept switching to ranibizumab biosimilar, and BSC, respectively. Conclusions Ranibizumab biosimilar was demonstrated as a cost-saving option compared to aflibercept across all subtypes of nAMD, irrespective of the perspectives considered.

Background: Intravitreal injection of anti-vascular endothelial growth factor is considered the first-line treatment for polypoidal choroidal vasculopathy. It has potential risks for circulatory system, which should be particularly carefully evaluated in older patients. In this case study, we aim to discuss the potential impact of this treatment regimen on cardiac health. Case presentation: This case report describes an elderly patient with no prior history of heart disease who exhibited unexpected heart enlargement and dysfunction. Throughout the patient's hospital stay, various potential causes were investigated, leading to the hypothesis that a 10-year history of intravitreal injections of anti-vascular endothelial growth factor could be related to the observed clinical manifestations. The patient was advised to discontinue this treatment, and after a 2-month follow-up period, there was a gradual improvement in the patient's cardiac structure and function. Conclusion: This manuscript highlights the importance of conducting cardiac examinations before and after anti-vascular endothelial growth factor treatment, especially for individuals at risk of heart diseases like the elderly. It emphasizes the need to carefully weigh the benefits and risks of treatment regimens to ensure optimal therapeutic outcomes. [ABSTRACT FROM AUTHOR]

Post-COVID-19 (PC) and post-COVID-19 vaccination (PCV) syndromes are considered emergent multidisciplinary disorders. PC/PCV small fiber neuropathy (SFN) was rarely described and its association with undifferentiated arthritis (UA) was never defined. We aimed to evaluate PC/PCV-UA associated with the recent onset of severe lower limb paresthesia, compare SFN positive (+) to negative (−) patients, and evaluate changes in biomarkers in SFN+ during treatments. Nineteen PC/PCV-UA-patients with possible SFN underwent skin biopsy at the Usl Tuscany Center (Florence) early arthritis outpatient clinic from September 2021 to March 2024. Eight selected SFN+ were compared to ten SFN− patients. In SFN+ patients, baseline joint ultrasound (US), electromyography (EMG), optical coherence tomography (OCT), and skin biopsy were repeated at six months. Moreover, SFN+ patients were clinically assessed by a 0–10 numeric rating scale for neurological symptoms and DAS28/ESR up to 12 months follow-up. SFN+ patients showed a lower intraepidermal nerve fiber density at histopathological examination of skin biopsies and a higher frequency of OCT and EMG abnormalities in comparison to SFN− patients. In SFN+ patients, US and DAS28/ESR significantly improved, while intraepidermal nerve fiber density did not significantly change at the six-month follow-up. Fatigue, motor impairment, burning pain, brain fog, and sensitivity disorders decreased at long-term follow-up (12 months). [ABSTRACT FROM AUTHOR]

To evaluate 2-year efficacy, durability, and safety of the bispecific antibody faricimab, which inhibits both angiopoietin-2 and VEGF-A. TENAYA (ClinicalTrials.gov identifier, NCT03823287) and LUCERNE (ClinicalTrials.gov identifier, NCT03823300) were identically designed, randomized, double-masked, active comparator-controlled phase 3 noninferiority trials. Treatment-naive patients with neovascular age-related macular degeneration (nAMD) 50 years of age or older. Patients were randomized (1:1) to intravitreal faricimab 6.0 mg up to every 16 weeks (Q16W) or aflibercept 2.0 mg every 8 weeks (Q8W). Faricimab fixed dosing based on protocol-defined disease activity at weeks 20 and 24 up to week 60, followed up to week 108 by a treat-and-extend personalized treatment interval regimen. Efficacy analyses included change in best-corrected visual acuity (BCVA) from baseline at 2 years (averaged over weeks 104, 108, and 112) and proportion of patients receiving Q16W, every 12 weeks (Q12W), and Q8W dosing at week 112 in the intention-to-treat population. Safety analyses included ocular adverse events (AEs) in the study eye through study end at week 112. Of 1326 patients treated across TENAYA/LUCERNE, 1113 (83.9%) completed treatment (n = 555 faricimab; n = 558 aflibercept). The BCVA change from baseline at 2 years was comparable between faricimab and aflibercept groups in TENAYA (adjusted mean change, +3.7 letters [95% confidence interval (CI), +2.1 to +5.4] and +3.3 letters [95% CI, +1.7 to +4.9], respectively; mean difference, +0.4 letters [95% CI, −1.9 to +2.8]) and LUCERNE (adjusted mean change, +5.0 letters [95% CI, +3.4 to +6.6] and +5.2 letters [95% CI, +3.6 to +6.8], respectively; mean difference, −0.2 letters [95% CI, −2.4 to +2.1]). At week 112 in TENAYA and LUCERNE, 59.0% and 66.9%, respectively, achieved Q16W faricimab dosing, increasing from year 1, and 74.1% and 81.2%, achieved Q12W or longer dosing. Ocular AEs in the study eye were comparable between faricimab and aflibercept groups in TENAYA (55.0% and 56.5% of patients, respectively) and LUCERNE (52.9% and 47.5% of patients, respectively) through week 112.

• The 30 days administration of polycarbophil vaginal gel (PCV) in treating symptoms of vaginal atrophy (VA) was effective in postmenopausal women, as previously published in perimenopausal women-. • The effect of treatment was more pronounced in post- than peri- mmenopausal women. • Treatment prolongation up to 210 days was safe and further improved vaginal atrophy and its symptoms in both peri- and postmenopausal women. This TRIPLE study was aimed to evaluate the efficacy of polycarbophil vaginal gel (PCV) in treating symptoms of vaginal atrophy (VA) of peri- and post-menopausal women. Sexually active women in peri- (n = 29) and post-menopause (n = 54) suffering from VA, were progressively enrolled and treated for 30 days with PCV. Those wishing to continue (n = 73) were treated for additional 180 days. PCV was administered as one application twice a week. The vaginal health index (VHI; range 5 to 25) and the visual analogue score (VAS range for 0 to 100 mm for each item) for vaginal dryness, irritation, and pain at intercourse, along with the global symptoms score (GSS; range 1 to 15) and treatment safety, were evaluated at baseline and after 30 days. In those continuing the treatment an evaluation was performed after additional 180 days. Women in peri and post-menopause were of 48.7 ± 3.3 years and 57.5 ± 5.7 years old., respectively. At baseline all outcomes were significantly worse (p<0.002) in postmenopausal group, except the VHI (p < 0.056). After 30 days VHI increased (p < 0.001) of 4.1 ± 0.5 (mean ± SE), and 5.1 ± 0.4 in peri- and post-menopausal women respectively. VAS of vaginal dryness decreased (p < 0.001) of −24.4 ± 3.6, and −52.7 ± 2.6 (p < 0.001), VAS of irritation decreased (p<0.001) of −18.6 ± 4.4 and −47.8 ± 3.2, VAS of pain decreased (p < 0.001) of −26.2 ± 4.3 and −55.6 ± 3.1 and the GSS decreased (p < 0.001) of −3.9 ± 0.3, and −4.9 ± 0.2, in peri and post-menopausal women, respectively. All the modifications were significantly greater (p < 0.001)(p < 0.032 for GSS) in postmenopausal women, and after 30 days all outcomes were similar in the two groups of women. In comparison to baseline, after 210 days of treatment VHI increased of 7.7 ± 0.3 (p < 0.001), VAS of vaginal dryness decreased of –53.6 ± 1.9 (p < 0.001) VAS of irritation of −42.6 ± 1.4 (p < 0.001) VAS of pain of −46.7 ± 2.3 (p < 0.001) and the GSS of −6.5 ± 0.2 ± 0.2 (p < 0.001). All outcomes improved (p < 0.001) over the values observed after 30 days of treatment (p < 0.001). No side effect was reported. In peri- and post-menopausal women PCV administration rapidly improves VA symptoms, and its prolongation up to 6 months further increases its efficacy. [ABSTRACT FROM AUTHOR]

Introduction: Central Serous Chorioretinopathy (CSC), a leading cause of vision loss, presents diverse treatment challenges based on its acute or chronic manifestation. Areas covered: In acute CSC, treatment typically involves observation, reserving intervention for cases where optimal vision is crucial for professional activities. Emerging evidence advocates the use of half-dose or half-fluence Photodynamic Therapy (PDT), directed by Indocyanine Green Angiography (ICGA) or Fluorescein Angiography (FA), to hasten subretinal fluid (SRF) resolution, improve vision, and minimize recurrence. Chronic CSC, on the other hand, increasingly favors half-dose PDT, a recommendation strengthened by studies such as the PLACE trial. CSC complicated by Choroidal Neovascularization (CNV) necessitates management through intravitreal anti-Vascular Endothelial Growth Factor (anti-VEGF) injections and/or half-dose PDT. In cases of polypoidal choroidal vasculopathy (PCV), a combination of anti-VEGF therapy with PDT proves beneficial. For scenarios where standard treatments are impractical, Eplerenone emerges as the primary oral medication. Methods: A literature search of all original articles was performed using the major online databases. The following keywords 'Central Serous Chorioretinopathy' and 'Treatment,' were searched in combination with 'Photodynamic therapy,' 'Focal Laser Photocoagulation,' 'Subthreshold Micropulse Laser' and 'Systemic treatments.' Expert opinion: Managing CSC requires a patient-centered approach. In acute CSC, careful monitoring and lifestyle modifications may suffice, while in chronic CSC, PDT is a primary therapeutic option.

Circumscribed choroidal hemangioma is a rare benign vascular choroidal tumor that may cause visual loss in regard to its location and/or be associated with either intraretinal or subretinal fluid leakage. We described the long-term good clinical outcome in two patients who underwent a single session of verteporfin photodynamic therapy (PDT) for the treatment of unilateral choroidal hemangioma and associated serous macular detachment with a follow-up duration of 13 and 14 years. PDT is a safe and effective therapy for the treatment of choroidal hemangioma and restores visual function in many cases without causing any apparent ocular or systemic side effects in the long run.

Background and Objectives: Our study compared the visual and anatomical outcomes of polypoidal choroidal vasculopathy (PCV) patients receiving intravitreal aflibercept (IVA) with or without photodynamic therapy (PDT) over 12 months. Materials and Methods: This retrospective study was performed for 60 eyes from 60 patients with treatment-naïve PCV. Thirty eyes were treated using IVA monotherapy (IVA group), and thirty eyes were treated using a combination of IVA with PDT (IVA/PDT group). The baseline characteristics, treatment outcomes, and retreatment rates were compared between the two groups over a one-year follow-up period. Results: The best-corrected visual acuity (BCVA) was found to have improved significantly in the IVA/PDT group at every 3-month visit. However, no significant BCVA improvement was observed in the IVA group. A significantly lower retreatment rate and higher dry macula rate were found in the IVA/PDT group than that in the IVA group. In the entire population of the study, a better baseline vision and younger age were associated with better final visual outcomes. Retreatment was associated with poor baseline BCVA and IVA monotherapy. Conclusions: The combination of IVA and PDT may offer superior visual improvement and a higher dry macula rate compared to IVA monotherapy in the treatment of PCV patients while requiring fewer retreatments over 12 months.

This study aimed to develop a quantitative analysis program of blood flow velocity by vessel diameter in neovascular age-related macular degeneration (nAMD) subjects using high-speed swept-source optical coherence tomography angiography. This retrospective, observational, cross-sectional study included 10 eyes of healthy volunteers and 4 eyes of patients with representative nAMD. Novel scan patterns and variable interscan time analysis were utilized to measure the flow parameter, a surrogate marker of blood flow velocity, by vessel diameter within different depths. Detected vessels at superficial and deep as well as outer retinal regions were categorized into three vessel diameters (major vessels (> 40 μm), medium vessels (20–40 μm), and capillaries (< 20 μm)). The flow parameter increased with enlarged vessel diameter in all participants at superficial and deep layer. All nAMD subjects, except for type 3 macular neovascularization (MNV), contained a structure dominated by medium vessels at outer retinal region. The mean flow parameter at outer retinal region was type 1 MNV (1.46 ms−1), type 1 + 2 MNV (0.98 ms−1), and polypoidal choroidal vasculopathy, including branching vascular networks (1.46 ms−1). This program provides the possibility to extract the blood flow information at different depths by vessel diameter types, which is considered to be useful tool for evaluating nAMD pathology and activity.

Clinical imaging provided by optical coherence tomography (OCT) and its variant, OCT-angiography (OCT-A), has revolutionised eyecare practice. The imaging techniques allow for the identification and quantification of ocular structures, supporting the diagnosis and prognosis of eye disease. In this review, an overview of the usefulness of OCT-A imaging in the diagnosis and management of a range of ocular conditions is provided when used in isolation or in combination with other imaging modalities and measures of visual function (visual field results). OCT-A imaging has the capacity to identify and quantify ocular vasculature non-invasively, thereby assisting the clinician in the diagnosis or to determine the efficacy of intervention in ocular conditions impacting retinal vasculature. Thus, additional clinically useful information can be obtained in eye diseases involving conditions such as those impacting retinal vessel occlusion, in diabetic retinopathy, inherited retinal dystrophy, age-related macular degeneration, choroidal neovascularisation and optic nerve disorders. Through a clinical case series, various ocular conditions are reviewed, and the impact of OCT-A imaging is discussed. Although OCT-A imaging has great promise and is already used in clinical management, there is a lack of set standards to characterise altered vascular features in disease and consequently for prognostication, primarily due to a lack of large-scale clinical trials and variability in OCT-A algorithms when generating quantitative parameters.

This study aims to investigate the relationship between pachychoroid spectrum disorders and retinitis pigmentosa (RP) or rod‑cone dystrophy through a comprehensive literature review. The purpose is to explore the association between these disorders, understand their underlying mechanisms, and summarize the existing hypotheses and opinions. A thorough review of the literature was conducted using PubMed, focusing on articles related to central serous chorioretinopathy (CSC), RP, pachychoroid pigment epitheliopathy, pachychoroid neovasculopathy, polypoidal choroidal vasculopathy, focal choroidal excavation, peripapillary pachychoroid neovasculopathy, and peripheral exudative hemorrhagic chorioretinopathy. Relevant studies were selected for a detailed narrative review and analysis. Several studies have reported the coexistence of CSC and RP, indicating a potential association between the two conditions. The dysfunction of the retinal pigment epithelium is proposed as a common factor. Choroidal thinning is observed in RP, but conflicting results exist regarding choroidal thickness (CT). While some studies support choroidal thinning in RP, others suggest preserved or increased thickness. Additionally, cases of pachychoroid neovasculopathy and polypoidal choroidal vasculopathy in RP have been reported, suggesting an overlap between these conditions. The literature suggests conflicting reports on CT changes in RP. Future research should focus on large‑scale studies using comprehensive imaging techniques, genetic analysis, and long‑term follow‑up to uncover the underlying mechanisms and determine the prevalence of pachychoroid spectrum disorders in RP patients.

Purpose: To assess the safety and efficacy of intravitreal Aflibercept (IVA) versus dexamethasone (DEX) implant for treating recalcitrant diabetic macular edema (DME) in pseudophakic eyes at 1‑year follow‑up. Design: Retrospective comparative case series. Participants: Data of all patients diagnosed with DME between January 2019 and December 2021, who underwent 4‑monthly doses of intravitreal ranibizumab but had persistent DME [central macular thickness (CMT) within 10% of baseline value] were extracted from a computerized database. Of these, only pseudophakic eyes that underwent either IVA or DEX implant and had at least 1‑year follow‑up were included for analysis. Methods: DEX implant was preferred before December 2020 and IVA after this time point. In the IVA group, patients were followed up every month while DEX were followed at least every 3 months. Reinjections were considered when vision dropped by at least 1 Snellen’s line or CMT increased by at least 10% from the previous visit in both groups. Main Outcome Measures: Comparison of change in vision and CMT at 1‑year follow‑up in DEX versus IVA groups. Results: Eighty‑four eyes of 84 patients aged 54.4 + 4.4 years were included, 39 (46%) received DEX and 45 (54%) received IVA. Groups were comparable for baseline vision and CMT. Vision improved equally in both groups from 0.83 + 0.15 logMAR to 0.52 + 0.10 logMAR at 3 months (P < 0.01) and then stabilized till 1 year. However, eyes in the IVA group were 6.5 times more likely (Odds ratio = 6.45, 95% CI = 1.3 – 31.9) to achieve >3‑line improvement in vision. The CMT reduction was also comparable between groups (‑169 + 51 in DEX vs. ‑174 + 49 in IVA, P = 0.67). More eyes in the IVA group required >3 injections (91% vs. 69% in DEX, P = 0.01). The IOP was significantly higher at 6 and 9 months in the DEX group and 5 eyes (13%) required IOP lowering medications. Conclusion: In pseudophakic eyes with recalcitrant DME not responding to ranibizumab, switching to IVA or DEX implant results in equal visual improvement and CMT reduction. Though >3‑line improvement occurs more frequently with IVA, this comes at the expense of a greater number of injections and follow‑up visits. [ABSTRACT FROM AUTHOR]

An ongoing global shortage of verteporfin (Visudyne®) limits the treatment possibilities for several chorioretinal diseases, including central serous chorioretinopathy, choroidal hemangioma, and polypoidal choroidal vasculopathy. Verteporfin is required to perform photodynamic therapy in these ocular diseases. Therefore, the current situation has a substantial impact on eye care worldwide. The worldwide supply of verteporfin appears to be manufactured by a single factory, which is situated in the United States. The distribution of verteporfin is done by different companies for different regions of the world. Official communication on the shortage by the responsible companies has been scarce and over the past years several promises with regards to resolution of the shortage have not been fulfilled. The delivery of new batches of verteporfin is at irregular intervals, unpredictable, and may not be fairly balanced between different regions or countries in the world. To ensure a fair distribution of available verteporfin within a country, several measures can be taken. In the Netherlands, a national committee, consisting of ophthalmologists, is in place to arrange this. On the European level, the European Union and European Medicine Agency have plans to monitor medicine shortages more closely and to intervene if necessary. With a more intensified monitoring and regulation of medicine supplies, future impending shortages may be prevented. Remarkably, the amount of medicine shortages is increasing, having a significant and sometimes irreversible impact on patient care. Thus, efforts should be undertaken to minimize the consequences and, whenever possible, to prevent future medicine shortages. [ABSTRACT FROM AUTHOR]

Purpose: To describe a patient with venous overload choroidopathy in whom venous bulbosities masqueraded as polyps and intervortex venous anastomosis mimicked a branching vascular network, giving the appearance of polypoidal choroidal vasculopathy. Methods: The patient had complete ophthalmic examination including indocyanine green angiography and optical coherence tomography. Venous bulbosities were defined on indocyanine green angiography as focal dilations in which the diameter of the dilation is two times that of the host vessel. Results: A 75-year-old woman presented with combined subretinal and subretinal pigment epithelium hemorrhages in the right eye. During indocyanine green angiography, focal nodular hyperfluorescent lesions connected to a network of vessels were observed, which looked like polyps and branching vascular network in polypoidal choroidal vasculopathy. In both eyes, the midphase angiogram had multifocal choroidal vascular hyperpermeability. There was late-phase placoid staining nasal to the nerve in the right eye. During enhanced depth imaging-optical coherence tomography evaluation, there were no retinal pigment epithelium elevations that would be expected with polyps or branching vascular network in the right eye. A double-layer sign was seen corresponding to the placoid area of staining. Diagnosis of venous overload choroidopathy and choroidal neovascularization membrane was made. She was treated with intravitreal antivascular endothelial growth factor injections for the choroidal neovascularization membrane. Conclusion: Indocyanine green angiography findings in venous overload choroidopathy may mimic polypoidal choroidal vasculopathy, but differentiation is essential because it has implications for treatment. Similar findings may have been misinterpreted in the past and may have previously contributed to conflicting clinical and histopathologic descriptions of polypoidal choroidal vasculopathy.

Introduction: We present a case of a patient with preceding vitreomacular traction (VMT) who developed a full-thickness macular hole (FTMH) following his sixth intravitreal aflibercept injection for the treatment of age-related macular degeneration and review the literature on risk factors and pathogenesis of this adverse event. Case Presentation: FTMH can occur after an extended number of repeat intravitreal injections in the setting of worsening vitreomacular adhesion or VMT. This patient’s FTMH was successfully treated surgically in a timely manner, and additional injections were resumed safely. Conclusions: Patients with an unexpected decrease in vision after intravitreal injections should be reevaluated with optical coherence tomography to rule out alternative pathology including vitreomacular interface abnormalities. FTMH, if present, should be treated promptly to allow for resumption of therapy as needed and visual optimization. [ABSTRACT FROM AUTHOR]

Radiation retinopathy (RR) is a major side effect of ocular tumor treatment by plaque brachytherapy or proton beam therapy. RR manifests as delayed and progressive microvasculopathy, ischemia and macular edema, ultimately leading to vision loss, neovascular glaucoma, and, in extreme cases, secondary enucleation. Intravitreal anti-VEGF agents, steroids and laser photocoagulation have limited effects on RR. The role of retinal inflammation and its contribution to the microvascular damage occurring in RR remain incompletely understood. To explore cellular and vascular events after irradiation, we analyzed their time course at 1 week, 1 month and 6 months after rat eyes received 45 Gy X-beam photons. Müller glial cells, astrocytes and microglia were rapidly activated, and these markers of retinal inflammation persisted for 6 months after irradiation. This was accompanied by early cell death in the outer retina, which persisted at later time points, leading to retinal thinning. A delayed loss of small retinal capillaries and retinal hypoxia were observed after 6 months, indicating inner blood‒retinal barrier (BRB) alteration but without cell death in the inner retina. Moreover, activated microglial cells invaded the entire retina and surrounded retinal vessels, suggesting the role of inflammation in vascular alteration and in retinal cell death. Radiation also triggered early and persistent invasion of the retinal pigment epithelium by microglia and macrophages, contributing to outer BRB disruption. This study highlights the role of progressive and long-lasting inflammatory mechanisms in RR development and demonstrates the relevance of this rat model to investigate human pathology.

Background/Objectives: This study aimed to assess the effectiveness of bi-monthly brolucimumab treatment in patients with neovascular age-related macular degeneration (nAMD) refractory to monthly aflibercept treatment. Methods: A retrospective chart review included 32 eyes of patients with refractory nAMD who switched from monthly intravitreal aflibercept treatment to bi-monthly intravitreal brolucizumab treatment. This study evaluated changes in visual acuity (VA), intraretinal fluid (IRF), subretinal fluid (SRF), pigment epithelial detachment (PED), and central macular thickness (CMT), at specific times as follows: baseline before switching (T0), 2 months after switching (T1), 4 months after switching (T2), and 6 months after switching (T3). Results: The mean best-corrected visual acuity (BCVA) did not significantly change across all time points (0.52 ± 0.12, 0.48 ± 0.27, 0.48 ± 0.28, and 0.50 ± 0.27 logarithms of the minimum angle of resolution in T0, T1, T2, and T3, respectively). CMT significantly decreased after additional brolucizumab injections compared to the baseline (218.2 ± 48.6 and 207.9 ± 49.8 μm, respectively; p = 0.001). The PED height also significantly decreased from 251.0 ± 165.4 to 154.4 ± 115.65 μm (p < 0.001), with complete resolution in nine patients (28%). The mean subfoveal choroidal thickness (SFCT) before brolucizumab treatment was 262.8 ± 79.7 μm, which decreased to 233.0 ± 71.2 μm (p = 0.001) after the first injection. The final SFCT also significantly decreased after additional brolucizumab injections compared to the baseline SFCT (p = 0.012). Conclusions: Bi-monthly brolucizumab treatment proves effective for patients refractory to monthly fixed aflibercept, resulting in positive anatomical changes without significant deterioration in visual acuity. This approach provides a promising prognosis while reducing the treatment burden on refractory patients. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to map the treatment burden for patients with wet age‐related macular degeneration (wAMD). Method: Patients with ongoing treatment with anti‐VEGF for wAMD at a Swedish eye unit underwent a survey about the time spent receiving treatment, caregiver assistance, way of transportation, self‐rated vision and negative experiences associated with the treatment such as discomfort, anxiety or transportation problems. Information about current visual acuity, number of treatments and current treatment intervals were obtained from medical records. Results: The study included 93 patients with an average age of 79.9 years, 68% were women. The average interval between treatments was 7.3 weeks, and 26% had active treatment in both eyes. On average, patients had to spend 2.7 h (2.4–2.9: 95% CI) per treatment and a caregiver assisted the patient in 58% of cases. Caregivers spent on average 2.6 h (2.5–2.8: 95% CI) per visit, and 19% needed to take time off work. The majority (91%) of patients did not experience any transportation problems associated with treatment. A multivariate logistic regression analysis showed a significantly lower odds ratio for discomfort with higher self‐rated vision and a significantly higher odds ratio for discomfort with longer treatment intervals. Discussion: Anti‐VEGF treatment is an effective treatment for wAMD. However, the relatively short treatment intervals place a considerable burden on patients and their relatives regarding time. Although the patients in this study had to spend a lot of time to receive treatment, the majority did not experience any problems associated with treatment. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the associations between fluid accumulation at different levels in the retina and visual outcome in polypoidal choroidal vasculopathy (PCV). Design: A retrospective observational study. Institutional setting. Study Population: A total of 91 eyes from 91 patients of PCV were included, with 65 receiving intravitreal aflibercept monotherapy and 26 receiving combined intravitreal ranibizumab and photodynamic therapy (PDT). Observation Procedures: Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) examination results were recorded at baseline and 3, 6, and 12 months after treatment. Main Outcome Measures: The correlations between visual outcomes and fluid biomarkers including intraretinal fluid (IRF), subretinal fluid (SRF), serous pigment epithelium detachment (PED), and hemorrhage at fovea were analyzed. Results: No differences in treatment outcomes were noted between patients receiving aflibercept and those receiving combined ranibizumab and PDT. IRF and hemorrhage at baseline predicted poorer vision at 3, 6, and 12 months. The presence of IRF was associated with poorer vision at 6 months and 12 months (p < 0.05 for all). The presence of SRF or PED was not associated with better vision at any time point. No differences in the correlations between fluid markers and visual outcomes were noted between thin and thick subfoveal choroidal thickness groups. Conclusions: For PCV, IRF and hemorrhage at baseline served as surrogates for poor visual prognosis after treatment, and IRF was a biomarker for poor vision during the treatment course. No fluid markers predicted good visual prognosis or had a positive impact on vision at any time point. [ABSTRACT FROM AUTHOR]

Purpose: We compared 12-month outcomes of eyes with polypoidal choroidal vasculopathy (PCV) with or without complete regression of polyps observed one month after three monthly intravitreal administrations (loading phase) of aflibercept (2.0 mg/0.05 mL) or brolucizumab (6.0 mg/0.05 mL). Methods: All patients underwent indocyanine green angiography at both baseline and 3 months after initial injection and were followed up monthly with an as-needed regimen for up to 12 months. A total of 62 patients with PCV were included: 30 eyes were treated with brolucizumab, and 32 were treated with aflibercept. Eyes with complete regression of polyps (regression group) had significantly smaller maximum polyp diameter and were more frequently treated with brolucizumab than those without complete regression (non-regression) group. Results: Best corrected visual acuity was comparable between the two groups at 12 months. Although the 12-month retreatment-free proportion was comparable between the two groups (33.0% versus 27.0%, p = 0.59), a retreatment-free period was significantly longer in the regression group than in the non-regression group (8.3 ± 3.3 versus 6.5 ± 3.6 months, p = 0.022), and the number of additional injections was significantly fewer in the regression group than in the non-regression group (1.2 ± 1.2 versus 3.0 ± 2.6, p = 0.007). Conclusions: Complete regression of polyps observed after the initial phase possibly prolongs the retreatment-free period and reduces the number of additional injections irrespective of aflibercept or brolucizumab.

Photodynamic therapy (PDT) with verteporfin involves intravenous administration of a photosensitizer followed by its laser light activation at the target site to inhibit aberrant choroidal vascularization. This narrative review provides an overview of the role verteporfin PDT plays in the management of chorioretinal conditions. A PubMed literature review of all English-language articles published through October 19, 2023, was conducted to identify relevant references. Verteporfin PDT has been shown to be safe and effective for the treatment of patients with choroidal neovascularization (CNV) due to neovascular age-related macular degeneration and is often used in combination with a vascular endothelial growth factor (VEGF) inhibitor. Additionally, patients with polypoidal choroidal vasculopathy, a subtype of neovascular age-related macular degeneration, also benefit from verteporfin PDT combined with a VEGF inhibitor for improving visual acuity. Verteporfin PDT has also been effective in treating patients with peripapillary CNV, as well as eyes with CNV due to ocular histoplasmosis and pathologic myopia. Reduced dose and/or fluence PDT protocols have been effective in patients with central serous chorioretinopathy while reducing adverse effects. In eyes with choroidal hemangioma, tumor regression and visual outcomes have been improved with verteporfin PDT treatment. Photodynamic therapy with verteporfin continues to play an important role in the management of chorioretinal conditions. [ABSTRACT FROM AUTHOR]

Purpose: To assess ocular pain in patients undergoing multiple intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) who have previous factors that may influence pain sensitivity. Methodology: This is a prospective, observational, case series study involving patients who underwent multiple (≥ 3) pro re nata intravitreal injections of ranibizumab or aflibercept to treat any cause of chorioretinal vascular disease. Ocular pain was assessed by the numerical analog scale during intravitreal injection. For this study, the main variable was ocular pain and the secondary variables included age, sex, previous history of glaucoma, primary retinal vascular disease, severe dry eye history, trigeminal pain, scleral buckle surgery, collagen diseases, fibromyalgia, severe migraine history, pars plana vitrectomy, scleral thickness measurements, and type of anti-VEGF. Results: In a total of 894 patients, 948 eyes (4822 intravitreal injections), 793 patients (88.6%) had ocular pain sensitivity between no pain to mild pain, 80 patients (8.9%) had moderate ocular pain, 15 patients (1.6%) had severe ocular pain, and 6 patients (0.7%) had extremely severe ocular pain. Patients with severe dry eye (p = 0.01) and previous history of scleral buckle surgery (p = 0.01) showed a significant correlation with ocular pain during intravitreal injection. Pars plana scleral thickness (> 550 um) and diabetic neuropathy were associated with ocular pain but did not meet the criteria for statistical significance (p = 0.09 and p = 0.06, respectively). Conclusion: Dry eye and prior scleral buckle surgery may contribute to pain associated with intravitreal injection. These issues should be taken into consideration in patients undergoing multiple intravitreal injections. [ABSTRACT FROM AUTHOR]

To compare the visual outcome and fluid features of a proposed biosimilar, CKD-701, versus the reference ranibizumab in eyes with polypoidal choroidal vasculopathy (PCV). This was a post hoc analysis of a phase 3 randomized clinical trial assessing the efficacy and safety of CKD-701 and ranibizumab. A total of 73 PCV eyes were assigned randomly to either CKD-701 (36 eyes) or ranibizumab (37 eyes). The mean changes in best-corrected visual acuity (BCVA), central retinal thickness (CRT), pigment epithelial detachment (PED) volume, and fluid features were compared. After three loading injections, the mean change in BCVA (letters) was +7.50 in the CKD-701 group and +6.32 in the ranibizumab group (p =.447). The changes in CRT and PED volume of the CKD-701 group (−107.25 ± 102.66 μm and −0.22 ± 0.46 mm3) were similar to those of the ranibizumab group (−96.78 ± 105.00 μm and −0.23 ± 0.54 mm3) (p =.668 and p =.943, respectively). Proportions of eyes with subretinal, intraretinal and sub-retinal pigment epithelium (RPE) fluids after three loading injections were not different between CKD-701 group (33.3%, 13.9% and 42.9%) and ranibizumab group (51.4%, 16.2% and 40.0%) (p =.071, p = 1.000 and p =.808). The visual and anatomical changes were similar between two groups at month 6 and 12 (all, p >.05). Biosimilar CKD-701 monotherapy resulted in comparable visual and anatomical changes to those achieved with reference ranibizumab in PCV eyes. [ABSTRACT FROM AUTHOR]

Purpose: To examine the long-term visual outcomes after initial treatment with combined photodynamic therapy (PDT) or aflibercept treat-and-extend (TAE) monotherapy in patients with pachychoroid neovasculopathy (PNV). Methods: Patients diagnosed with PNV, initially treated with PDT combined with anti-vascular endothelial growth factor (VEGF) or intravitreal aflibercept (IVA) monotherapy in the TAE protocol and followed up for at least 6 months, were included in the study. Medical records were retrospectively reviewed. Survival analysis was performed, in which deterioration in logMAR visual acuity by 0.1 or 0.3 is defined as "death." The annual number of treatments was also analyzed. Sub-analysis was performed on 33 patients diagnosed with PNV without polypoidal lesions. Results: This study included 46 patients (23 in the initial combined PDT group and 23 in the IVA TAE group). Mean age, sex, mean baseline logMAR visual acuity, or duration of observation (3.6 ± 3.2 years vs. 3.1 ± 1.9 years) in both groups were comparable. As for visual outcome, no significant differences were found in survival analysis based on worsening of 0.1 or 0.3 logMAR (3-year survival; 26% vs. 26%, 91% vs. 90%, respectively). Meanwhile, the additional number of anti-VEGF injections per year was significantly lower in the initial combined PDT group than in the IVA TAE group (1.0 ± 1.3 vs. 4.1 ± 1.5, p < 0.0001). No significant differences were found in the number of additional PDTs per year (0.07 ± 0.20 vs. 0.02 ± 0.09, p = 0.27). Similar results were found in a sub-analysis of 33 patients without polyps. Conclusion: In the treatment of PNV, regardless of the presence of polyps, the long-term visual outcomes were similar between the initial combined PDT and IVA TAE monotherapy. However, the annual number of anti-VEGF injections was lower in the initial combined PDT group than in the aflibercept TAE group, whereas that of PDT was comparable. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the distinct characteristics between young and elderly polypoidal choroidal vasculopathy (PCV) patients based on the pachy- or non-pachychoroid phenotypes. Methods: PCV patients treated with intravitreal injections of Conbercept based on the 3 + PRN regimen from 27 centers of China PCV Research Alliance were included. Patients were categorized into the young and the elderly aged group based on the cut-off point determined using the Youden method according to the pachychoroid phenotypes. The characteristics of past medical history, lifestyle factors, fundus manifestations, and treatment response between the subgroups were analyzed. Results: Three hundred eight eligible patients were included. Multivariate logistic regression showed a significant association between age and PCV subtype classification (OR = 0.921, P = 0.002). A cutoff age of 64.5 effectively distinguished between pachychoroid PCV and non-pachychoroid PCV (P < 0.001). Elderly PCV patients had a higher incidence of hypertension history (P = 0.044) but a lower incidence of diabetes history (P = 0.027). In terms of lifestyle, smoking history (P = 0.015) and staying up late (P = 0.004) were more significant in the young group of PCV patients. For clinical characteristics, the proportion of hemorrhagic PCV in the young group was significantly higher (P = 0.038), with a higher proportion of sharp-peaked PED (P = 0.049), thicker choroid (P < 0.001) but a lower portion of double-layer sign (P = 0.023) in OCT. Both groups showed significant anatomical changes compared to baseline in each follow-up period (P < 0.05), with the young group having a higher proportion of good anatomical response after the first injection (P = 0.009). Conclusion: PCV patients stratified by subtype exhibit distinct characteristics between the young and elderly groups. [ABSTRACT FROM AUTHOR]

Chronic thromboembolic pulmonary hypertension (CTEPH) is a debilitating disease characterized by thrombotic occlusion of pulmonary arteries and vasculopathy, leading to increased pulmonary vascular resistance and progressive right‐sided heart failure. Thrombotic lesions in CTEPH contain CD68+ macrophages, and increasing evidence supports their role in disease pathogenesis. Macrophages are classically divided into pro‐inflammatory M1 macrophages and anti‐inflammatory M2 macrophages, which are involved in wound healing and tissue repair. Currently, the phenotype of macrophages and their localization within thrombotic lesions of CTEPH are largely unknown. In our study, we subclassified thrombotic lesions of CTEPH patients into developing fresh thrombi (FT) and organized thrombi (OT), based on the degree of fibrosis and remodeling. We used multiplex immunofluorescence histology to identify immune cell infiltrates in thrombotic lesions of CPTEH patients. Utilizing software‐assisted cell detection and quantification, increased proportions of macrophages were observed in immune cell infiltrates of OT lesions, compared with FT. Strikingly, the proportions with a CD206+INOS− M2 phenotype were significantly higher in OT than in FT, which mainly contained unpolarized macrophages. Taken together, we observed a shift from unpolarized macrophages in FT toward an expanded population of M2 macrophages in OT, indicating a dynamic role of macrophages during CTEPH pathogenesis.
