Purpose: To test to what degree retinal fluid (RF) after the loading phase and at the end of year 1 predicts long-term functional outcomes in neovascular macular degeneration (nAMD), as do macular (MA) atrophy, treatment density and treatment interval extension. Methods: In this retrospective single-center cohort study, a consecutive series of eyes with treatment-naïve nAMD followed under a treat-and-extend (T&E) protocol followed over ≥2 years. Best-corrected visual acuity (BCVA), presence of retinal fluid (RF) and macular atrophy (MA) were registered along with central retinal thickness (CRT) and treatment density over time. The relationship between these variables was tested by regression analysis. Results: A total of 433 eyes were followed for 4.9 ± 2.2 years. A series of univariate analyses were run to select the covariates for the final multivariate regression model. CRT after loading, time to dryness, intraretinal fluid and MA after one year were found to predict visual function over 2 to 5 years. A final regression model was adjusted for visual acuity (VA) at baseline and showed that CRT after loading was predictive only in the short term (2 years) and that MA had the greatest predictive value for VA after 2 to 5 years. Intraretinal fluid (IRF) significantly predicted VA only after 4 years. The final regression model explained 21 to 32% of the variation in VA. Conclusions: In this large retrospective cohort, the presence of MA after one year was the strongest predictor of VA after 2 to 5 years, explaining a vision loss of 13 to 20 letters. The presence of IRF and SRF at any point of time had a comparably weak predictive potential for the outcomes over 5 and more years. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy of systemic tumor necrosis factor-alpha inhibitors (TNFi) in the treatment of non-infectious uveitis (NIU). Methods: This Swiss multicenter retrospective cohort study included patients with NIU requiring TNFi during the period from 2001 to 2018. Risk factors for the occurrence of new complications were identified using Cox regression analysis and hazard ratios (HR). Results: Seventy-one patients (126 eyes; mean age 40.6 ± 14.4 years, mean duration of uveitis 46.0 ± 61.8 months) were followed for 40.2 ± 17.3 months after addition of TNFi. Under TNFi, visual acuity improved from 0.2 ± 0.3 to 0.1 ± 0.3 logMAR (p < 0.001). The portion of patients under systemic corticosteroids decreased from 81.7% to 25.4% (p < 0.001), while that for conventional synthetic disease-modifying anti-rheumatic drugs insignificantly decreased from 63.4% to 50.7% (p > 0.05). In 80.2% of eyes, complications were present at baseline with epiretinal gliosis (39.7%), cataract (41.3%) and macular edema (ME; 27.8%) being the most common. New complications under TNFi were encountered in 49.2% of eyes, also including recurrence (5 eyes) or new onset of ME (14 eyes). The need for switching of TNFi was associated with further complications (HR 3.78, p = 0.012). Conclusion: Although the efficacy and tolerability of TNFi in a real-life setting are favorable, treatment is often initiated late, i.e., after many eyes have already developed complications. Even with TNFi, new complications, particularly ME, cannot be completely avoided. Further research is needed to assess the impact of earlier initiation of TNFi therapy. [ABSTRACT FROM AUTHOR]

Background/Objectives: Diabetic macular edema (DME) is a significant cause of visual impairment, often treated with anti-vascular endothelial growth factor (anti-VEGF) agents. However, some patients do not respond adequately to this treatment. This study aims to evaluate the contribution of the intravitreal dexamethasone (DEX) implant as a second-line treatment in DME patients with insufficient response to anti-VEGF therapy or with high treatment burden. Methods: This retrospective multicenter cohort study was conducted across seven clinical sites in Switzerland. The study included eyes with active DME that had been pretreated with anti-VEGF for at least six months before receiving DEX therapy. Data were extracted from electronic patient records, focusing on best-corrected visual acuity (BCVA), central subfield thickness (CST), and injection frequency. Results: A total of 95 eyes from 89 patients (38.8% females, mean age 65.6 ± 9.1 years, follow-up time 80.6 ± 38.5 [13.5–166.7] months) were analyzed. Prior to the first DEX implant, eyes had undergone an average of 16.0 ± 13.3 anti-VEGF injections over 32.5 ± 22.4 months. Post-DEX treatment, 22.1% of eyes received DEX monotherapy, 44.2% received a combination of DEX and anti-VEGF, 25.3% continued with anti-VEGF monotherapy, and 8.4% received no further treatment. The number of anti-VEGF injections decreased significantly from 6.4 ± 3.1 in the year before DEX to 1.6 ± 2.4 in the year after DEX (p < 0.001). BCVA remained stable (0.4 ± 0.3 logMAR at baseline, 0.4 ± 0.5 logMAR at 24 months, p = 0.2), while CST improved from 477.7 ± 141.0 to 320.4 ± 125.5 μm (p < 0.001), and the presence of retinal fluid decreased from 98.0% to 61.1% (p = 0.021). During follow-up, 26.3% of eyes required glaucoma medication, 4.2% underwent glaucoma surgery, and 1.1% needed cataract surgery. Conclusions: In real-world clinical settings, the addition of DEX to anti-VEGF therapy in DME patients significantly reduces treatment burden and retinal fluid while maintaining visual function. Treatment decisions should balance anatomical and functional outcomes, considering individual patient needs. [ABSTRACT FROM AUTHOR]

Purpose: To assess the impact of switching to, or adding, an intravitreal dexamethasone implant (Dex; Ozurdex®) in anti-vascular endothelial growth factor (VEGF) therapy on disease stability and treatment intervals in eyes with neovascular age-related macular degeneration (nAMD) and persistent disease activity and high treatment demand. Methods: This retrospective noncomparative multicenter longitudinal case series included pseudophakic eyes with nAMD and persistent retinal fluid despite regular anti-VEGF therapy (ranibizumab or aflibercept) that received at least 1 intravitreal Dex implant. Visual acuity, central retinal thickness (CRT), and intraocular pressure were recorded before, and after, the addition of Dex to anti-VEGF therapy. Results: Sixteen eyes of 16 patients met the inclusion criteria of persistent fluid despite anti-VEGF therapy, under treatment intervals of ≤7 weeks in 14 instances. Patients were 80.9 ± 7.4 years old and had received 25.5 ± 17.4 anti-VEGF injections before Dex over a period of 36.4 ± 21.9 months before switching. The treatment interval increased from 5.5 ± 3.2 weeks between the last anti-VEGF and first Dex injection to 11.7 ± 7.3 weeks thereafter (P = 0.022). CRT remained stable (385.3 ± 152.1, 383.9 ± 129.7, and 458.3 ± 155.2 μm before switching as well as 12 and 24 months after switching; P = 0.78 and P = 0.36, respectively). An insignificant mean short-term early increase in visual acuity was not sustained over time. Conclusions: The addition of Dex resulted in a relevant and sustained increase in treatment intervals, whereas CRT and visual acuity remained stable in these difficult-to-treat eyes. It may be discussed whether inflammation or other steroid-responsive factors play a significant role in cases of nAMD with nonsatisfactory responses to anti-VEGF. [ABSTRACT FROM AUTHOR]

PurposeMethodsResultsConclusionsJanus kinase (JAK) inhibitors have recently been used to treat patients with biologic refractory noninfectious uveitis (NIU). This narrative review updates the current evidence relevant for their application in patients with refractory NIU.A literature search was performed for articles published until October 2023 in the PubMed, Scopus, and CENTRAL databases using the key terms “noninfectious uveitis” and “Janus kinase inhibitor” or “JAK inhibitor” without any exclusion criteria. Published articles were selected based on their clinical focus, relevance for ocular disease, time since publication and study design reflecting their scientific soundness with a critical appraisal of drug safety aspects.Janus kinases are transmembrane signaling proteins. Their inhibition has shown therapeutic potential experimentally and in patients with multiple immune-mediated diseases, including NIU. JAK inhibitors differ from biological agents in that they inhibit not one specific but multiple cytokines. These agents can be ingested orally and seem superior to adalimumab for most indications. While there is no doubt regarding their efficacy in treating immune-mediated inflammatory diseases, reports regarding their safety are increasing, and the findings are generally confusing and contradictory. Since substantiated information about their specific safety profiles in patients with inflammatory eye disease is lacking, their position in the therapeutic algorithm for uveitis has yet to be determined.In the absence of evidence from controlled clinical trials, JAK inhibitor therapy is still rendered experimental and currently considered only for sight-threatening uveitis. JAK inhibitors may be considered for specific NIU entities for which there is insufficient response or secondary loss of response to conventional or biologic disease-modifying drugs.

To assess the efficacy of tumor necrosis factor-alpha inhibitors (TNFi) on uveitic macular edema (ME) unresponsive to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). This multicenter retrospective study included patients with uveitic ME persisting despite csDMARDs. The effect of an additional TNFi on central retinal thickness (CRT), best corrected visual acuity (BCVA) and corticosteroid need was evaluated. Thirty-five eyes (26 patients, mean age 42.9 ± 15.2 years) were included. CRT decreased from 425 ± 137 µm to 294 ± 66 µm (p <.001) and 280 ± 48 µm (p <.001) at 1 and 4 years of follow-up, respectively. BCVA improved from 0.28 ± 0.22 to 0.21 ± 0.48 (1 year, p =.013) and 0.08 ± 0.13 logMAR (4 years, p =.002). The proportion of patients requiring systemic corticosteroids decreased from 88.5% to 34.8% (1 year) and 15.4% (4 years). The addition of a TNFi resulted in an improvement of CRT and BCVA for up to 4 years in uveitic ME but rescue treatments were needed for some patients. [ABSTRACT FROM AUTHOR]
