Purpose: To present paradoxical reaction (PR) in three cases with ocular tuberculosis (OTB) treated with antitubercular therapy (ATT), highlighting diagnostic challenges and treatment strategies., Methods: We retrospectively reviewed clinical records of three OTB patients presenting with paradoxical worsening after ATT initiation at two Brazilian university hospitals., Results: The patients (2 males, 1 female) experienced worsening clinical presentation (increased inflammation, vision loss) within two to three weeks after initiating ATT. One patient who was HIV-positive with unilateral multifocal choroiditis developed PR soon after starting antiretroviral therapy. The second patient presented with a choroidal tuberculoma in both eyes. The third patient also had multifocal choroiditis and developed a localized choroidal elevation with a double-layer sign as a manifestation of PR. All patients were maintained on ATT therapy in association with corticosteroids and experienced improvement of inflammatory signs., Conclusion: This case series highlights the potential for PR in OTB patients. Close monitoring and prompt therapeutic adjustments are crucial for management success.

Purpose: This retrospective case series aimed to assess the concordance between clinical diagnoses of punctate inner choroidopathy and multifocal choroiditis and panuveitis (MCP) using the 2021 Standardization of Uveitis Nomenclature Working Group criteria., Methods: Using the medical records of the patients, the authors reevaluated 100 eyes of 75 patients with idiopathic multifocal chorioretinal inflammatory lesions based on Standardization of Uveitis Nomenclature criteria and compared the result with the clinical diagnosis., Results: Of 100 eyes, 29 eyes (29%) were diagnosed as punctate inner choroidopathy and 15 eyes (15%) were diagnosed as MCP using Standardization of Uveitis Nomenclature criteria, and 56 (56%) eyes could not be diagnosed as either. Clinically diagnosed punctate inner choroidopathy eyes were significantly more myopic than the clinically diagnosed MCP eyes (mean spherical equivalent -6.65 ± 4.63 vs. -3.85 ± 2.31, P = 0.01). Sixteen eyes with vitreous inflammation were all clinically diagnosed as MCP, but four (25%) could not be diagnosed as MCP using Standardization of Uveitis Nomenclature criteria., Conclusion: The existing diagnostic criteria showed limitations in capturing all clinical cases of punctate inner choroidopathy or MCP, and adding or revising criteria on features such as vitreous inflammation or myopia could be considered to enhance diagnostic accuracy.

Purpose: To investigate peripapillary atrophy and macular chorioretinal scars in eyes affected by multifocal choroiditis and panuveitis., Methods: This retrospective cohort study reviewed the medical records, fundus photographs, and spectral-domain optical coherence tomographic scans of 31 eyes from 19 patients., Results: Patients had a mean age of 45 years (range 24-69 years). The average follow-up duration was 7 years (range, 2.5-14.5 years), with 14 patients undergoing immunosuppressive treatment. In the group of 31 eyes, 20 showed peripapillary plumes of ill-defined hyperreflectivity at the termination border of the retinal pigment epithelium. These plumes, extending from bare Bruch membrane to the outer nuclear layer, sometimes undermined the adjacent retinal pigment epithelium. They responded to corticosteroid treatment and resembled the material under the retinal pigment epithelium in acute lesions. Among 20 eyes with these peripapillary inflammatory lesions, 16 (80%) experienced increased atrophy, in contrast to none in the eyes without these lesions ( P < 0.001). Similar patterns were observed at the edges of macular chorioretinal atrophy. This observation occurred in patients using immunosuppressive medication who were otherwise thought to be under adequate control., Conclusion: In patients with multifocal choroiditis and panuveitis, previously unrecognized plumes of smoldering inflammatory activity at the borders of chorioretinal atrophy appears to be linked to atrophy expansion. The recognition of this phenomenon may require a reappraisal of treatment of multifocal choroidopathies to help mitigate the expansion of atrophy in these eyes.

Burkholderia cepacia complex (BCC) encompasses opportunistic pathogen with various clinical manifestations ranging from no symptoms to severe respiratory infections and septicemia. Central nervous system infections caused by BCC are rare. To the best of our knowledge, we present the first reported case of choroid plexitis caused by BCC after severe COVID-19. A 67-year-old woman who had been previously diagnosed with COVID-19 presented with a mild fever and headache. Gadolinium-enhanced T1-weighted brain magnetic resonance imaging showed contrast effects in the right choroid plexus and encapsulated abscess. Gram staining of cerebrospinal fluid revealed the presence of gram-negative rods. Broad-range polymerase chain reaction amplification of 16S ribosomal RNA from the cerebrospinal fluid, followed by sequence analysis, identified BCC; thus, choroid plexitis caused by BCC was diagnosed. After prolonged antimicrobial treatment with a multiantibiotic regimen, the patient recovered completely. This case highlights the importance of long-term therapy with a carefully selected multiantibiotic regimen to achieve complete recovery after BCC infection., Competing Interests: Declarations of competing interest The authors have no competing interests to declare., (Copyright © 2024.

Background: Serpiginous-like choroiditis (SLC) denotes ocular tuberculosis (TB), in the presence of positive tuberculin skin test (TST) or interferon gamma release assay (IGRA)., Methods: Retrospective review of SLC patients from a TB-endemic country, with negative TST and IGRA tests, but responsive to anti-TB therapy., Results: Fifteen patients (13 bilateral) with active SLC  were included.   Eleven (73.3%) patients had received corticosteroids ± immunosuppressive therapy prior to presentation. Chest radiographic abnormalities were found in four (26.7%) patients. We treated all patients with a combination of anti-TB therapy (ATT) and corticosteroids. Paradoxical worsening was noted in nine (60%) patients, complete resolution of lesions in 12 (80%), persistent inflammation (post-ATT) in one, while two were yet to complete ATT. None had recurrence after complete resolution of lesions (median follow-up of 71 weeks [range 15-676 weeks])., Conclusions: TB-SLC may present with negative TST and IGRA tests but may still have clinical appearance, and treatment response, like test-positive disease.

Introduction: Serpiginous choroiditis presents with large yellow-white exudative lesions that occur near the optic nerve papillae, that progresses slowly with repeated relapses and cures. Although infection and autoimmunity have been implicated, the cause is unknown., Methods: A man was diagnosed with serpiginous choroiditis on clinical and other examinations. He started treatment with oral corticosteroids, cyclophosphamide, adalimumab, azathioprine, rituximab, and mycophenolate mofetil. Only the steroids and cyclophosphamide had a therapeutic effect. Plasma exchange was initiated, and the lesions quickly resolved., Results: Disease control has been maintained by plasma exchange and cyclophosphamide during flare-ups in the fall and winter, suggesting that plasma exchange is effective in the treatment of serpiginous choroiditis., Conclusion: The reproducible response with each recurrence suggests a strong association between the disease and autoimmunity. Furthermore, that some, as yet unknown, autoantibodies are involved in the pathogenesis of serpiginous choroiditis., (© 2024 International Society for Apheresis and Japanese Society for Apheresis.)

Purpose: The aim is to analyze automated quantification of choriocapillaris flow deficit (CCFD) on swept-source (SS)-optical coherence tomography angiography (OCTA) in tubercular serpiginous-like choroiditis (TBSLC)., Methods: In this prospective study, automated CCFD calculations were performed on SS-OCTA and compared with CCFD areas on indocyanine green angiography (ICGA). Patients were divided into two groups based on the occurrence of paradoxical worsening (PW)., Results: Twenty-nine eyes (29 subjects; 18 males; mean age: 33±12 years) were included. The mean CCFD at baseline was 34.9 ± 4.3% on OCTA in eyes without PW and 35.4 ± 5.0% on SS-OCTA with PW (p = .77). At 4 and 12 weeks, CCFD on SS-OCTA improved to 30.6 ± 3.9% and 28.0 ± 4.2% (p < .001) without PW, respectively, and increased to 42.9 ± 4.4% and 48.8 ± 4.1% (p < .001) with PW, respectively. The SS-OCTA CCFD correlated well with ICGA (r = 0.48; p < .001)., Conclusions: Automated quantitative serial assessment of CCFD on SS-OCTA can serve as a useful biomarker of disease activity in eyes with TBSLC.

Purpose: To compare various ocular thermography parameters in posterior scleritis (PS), choroiditis (choroidal granuloma [CG], Vogt-Koyanagi-Harada [VKH] syndrome), central serous chorioretinopathy (CSCR), and healthy controls., Methods: This retrospective, observational, comparative study evaluated cases undergoing ocular thermography between April 2017 and October 2023. The study groups included cases of PS, CG, and VKH, while the control group comprised CSCR cases and healthy individuals. Various thermography parameters were assessed, which were as follows: Ocular surface temperature (OST), central corneal temperature (CCT), average scleral temperature (ST), nasal scleral temperature (nST), temperature difference between both the eyes (∆t), and difference between scleral and corneal temperatures (ST - CCT, nST - CCT)., Results: It was found that ∆t was significantly higher in the PS group compared to the CG ( P = 0.005), CSCR ( P = 0.0001), and control groups (dilated control: P =0.006, undilated control: P = 0.0001). ST - CCT and nST - CCT were significantly higher in the undilated control and CSCR groups and significantly lower in the PS group. ST - CCT and nST - CCT showed less difference in the affected eyes compared to contralateral healthy eyes of PS and CG cases. OST, CCT, ST, and nST displayed statistically insignificant differences across all groups., Conclusion: It is advisable to focus on temperature differences between the affected and healthy eyes, or the difference between the central corneal and scleral temperature of the affected eye, utilizing parameters such as ∆t, ST - CCT, and nST - CCT. These composite parameters offer a more effective approach than individual measurements like OST, CCT, ST, and nST. Thermography can serve as a screening tool to suspect and differentiate PS., (Copyright © 2024 Copyright: © 2024 Indian Journal of Ophthalmology.)

Purpose: To assess the effect of corticosteroids (CS) on choroidal neovascularization (CNV) occurrence and recurrence of activity over 2 years in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC)., Methods: Retrospective longitudinal study. Previous use of CS was analyzed between group without CNV and group with CNV occurrence and recurrence., Results: Thirty-six patients were included. Patients with CNV were less likely to have received CS in the 6 months following PIC or MFC diagnosis (17% versus 65%, p-value = 0.01). Patients with CNV who had a recurrence of neovascular activity were less likely to have received a previous CS therapy (20% versus 78%; odds ratio = 0.08, p-value = 0.005)., Conclusions: This study suggests that patients with PIC and MFC should be treated by CS to prevent CNV development and decrease CNV recurrences.

Abstract Background Multifocal choroiditis (MFC) is multi-inflammatory lesions that occur in the retinal pigment epithelium (RPE) and the choriocapillaris. Optical examinations are the major diagnostic methods to diagnose the disease. Objective To examine patients with different types of MFC by multiple imageological methods. To summarize the imageology features of different types of MFC to make a medical examination guideline for clinician practices. Method All of the patients who included in the study received examinations of fundus color photography, infrared fundus photography, fundus auto fluorescence (FAF), fluorescein fundus angiography (FFA), and optical coherence tomography (OCT), respectively. Finally, imageology features of different types of multifocal choroiditis were summarized. Results A total of 51 eyes from 28 patients with diagnosed MFC were included in the study. These patients consisted of 10 males and 18 females aged from 31 to 49 (mean age: 41.5 ± 0.8). 23 patients had MFC on both eye whilst 5 had monocular disease. The MFC lesions were classified as active inflammatory lesions, inactive inflammatory lesions, inflammatory lesions secondary active choroidal neovascularization (CNV) and inflammatory lesions secondary inactive CNV according to literature reports and comprehensive fundus imaging examinations. Conclusion Examinations via fundus color photography, infrared fundus photography, FAF, FFA and OCT indicate typical imageological signals of different types of MFC. These imageology tests can greatly assist the clinicians to identify the MFC and provide proper therapies.

Purpose: To evaluate the influence of immunomodulatory therapy (IMT) on visual and treatment outcomes of inflammatory choroidal neovascularization (iCNV) in patients affected by multifocal choroiditis (MFC), and to compare them to patients treated with steroids as needed., Design: Multicenter retrospective matched cohort study., Methods: Patients affected by MFC with iCNV were divided into a IMT group and a "steroids as needed" group and matched according to the time between diagnosis and beginning of systemic treatment. Visual acuity (VA), number of anti-vascular endothelial growth factor (VEGF) intravitreal injections, and number of iCNV reactivations during 2 years of follow-up after treatment initiation were compared between the 2 groups., Results: A total of 66 eyes of 58 patients were included, equally divided into the 2 groups. Patients in the IMT group had a lower relative risk (RR) of iCNV reactivation (0.64, P = .04) and of anti-VEGF intravitreal injection retreatment (0.59, P = .02). Relapses of MFC-related inflammation were independently associated with a higher RRs of iCNV reactivation (1.22, P = .003). Final VA was higher in the IMT compared to the steroids as needed group (mean [SD], 69.1 [15.1] vs 77.1 [8.9] letters, P = .01), and IMT was associated with greater VA gains over time (+2.5 letters per year, P = .04)., Conclusions: IMT was associated with better visual and treatment outcomes in MFC complicated by iCNV compared to steroids as needed. The better outcomes of the IMT group and the association between MFC-related inflammation and iCNV reactivations highlight the need for tighter control of inflammation to prevent iCNV relapses and visual loss., (Copyright © 2024 The Authors.

Inflammation plays a key role in the induction of choroidal neovascularization (CNV). Inflammatory choroidal neovascularization (iCNV) is a severe but uncommon complication of both infectious and non-infectious uveitides. It is hypothesized that its pathogenesis is similar to that of wet age-related macular degeneration (AMD), and involves hypoxia as well as the release of vascular endothelial growth factor, stromal cell-derived factor 1-alpha, and other mediators. Inflammatory CNV develops when inflammation or infection directly involves the retinal pigment epithelium (RPE)-Bruch's membrane complex. Inflammation itself can compromise perfusion, generating a gradient of retinal-choroidal hypoxia that additionally promotes the formation of choroidal neovascularization in the course of uveitis. The development of choroidal neovascularization may be a complication, especially in conditions such as punctate inner choroidopathy, multifocal choroiditis, serpiginous choroiditis, and presumed ocular histoplasmosis syndrome. Although the majority of iCNV cases are well defined and appear as the "classic" type (type 2 lesion) on fluorescein angiography, the diagnosis of iCNV is challenging due to difficulties in differentiating between inflammatory choroiditis lesions and choroidal neovascularization. Modern multimodal imaging, particularly the recently introduced technology of optical coherence tomography (OCT) and OCT angiography (noninvasive and rapid imaging modalities), can reveal additional features that aid the diagnosis of iCNV. However, more studies are needed to establish their role in the diagnosis and evaluation of iCNV activity.

Background/aims: Birdshot uveitis (BU) is a chronic autoimmune posterior uveitis, mostly affecting middle-aged Caucasians. There is a strong association with HLA-A29 and T-cell activation. Safety and efficacy of abatacept, an inhibitor of T-cell costimulation, is tested in active BU., Methods: Fifteen patients with active BU were treated with monotherapy of weekly subcutaneous injections of abatacept 125 mg/mL. Time-to-treatment failure was evaluated as a primary outcome. The secondary objective was to evaluate the utility of different outcome measures to monitor disease activity. Safety was evaluated by adverse event reporting and serial blood analyses., Results: At the year-1 endpoint, there was significant improvement in vitreous haze grade (p=0.0014), central choroidal thickness (CCT) (p=0.0011), Fluorescein Angiography (FA) Score (p=0.0014), Indocyanine Green Angiography (ICGA) Score (p<0.001) and total dual FA-ICGA Score (p<0.001). Best corrected visual acuity (BCVA) (p=0.8354) and central retinal thickness (CRT) (p=0.3549) did not change significantly. There were no serious adverse events reported. In total, 4 out of 15 patients left the trial during year 1 of whom 2 experienced treatment failure., Conclusions: Abatacept is very efficacious to treat both retinal vasculitis and choroiditis in patients with BU and is well tolerated. BCVA and CRT are inadequate to monitor disease activity. On the other hand, CCT is a promising non-invasive tool to detect treatment response in early active BU and dual FA-ICGA Score is very helpful to evaluate retinal vasculitis and choroiditis quantitatively., Trial Registration Number: NCT03871361., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Multiple evanescent white dot syndrome (MEWDS)-like features is a rare condition triggered by a macular disease or iatrogenic injury, exhibiting MEWDS changes in the fundus. This study aims to describe the multimodal imaging features and outcomes of multifocal choroiditis/punctate inner choroidopathy (MFC/PIC) lesions with MEWDS-like features., Methods: Six cases were studied retrospectively. All cases were given regional and oral corticosteroids., Results: All cases showed an isolated juxtafoveal yellowish-white MFC/PIC lesion with disruption of RPE-Bruch's membrane-choriocapillaris complex (RPE-BM-CC), subretinal hyperreflective materials and choroidal thickening on optical coherence tomography. Two weeks after presentation, the grayish-white dots disappeared spontaneously and the corticosteroids were given. After four weeks, the ellipsoid zone (EZ) around the lesion and hyper-autofluorescence resolved. After 13 weeks, five cases showed shrinkage of the juxtafoveal lesion and restoration of foveal EZ. After six months, the juxtafoveal lesion became pigmented. Only one case developed type 2 choroidal neovascularization., Conclusions: The clinical course of MEWDS-like manifestations is still evanescent in our cases. The yellowish-white juxtafoveal MFC/PIC lesions with disruption of RPE-BM-CC and choroidal thickening showed a well-controlled prognosis after corticosteroid treatment., (© 2024. The Author(s).)

Purpose: To report a case of secondary bilateral choroiditis in a patient with primary Sjögren's syndrome(pSS)., Study Design: Case report., Results: A 69-year-old woman visited our hospital for consultation due to decreased visual acuity in both eyes for 1 month. At the first visit, best corrected visual acuity (BCVA) was 0.2 and 0.3 in her right and left eyes, respectively. Intraocular pressure values were 15 mmHg and 16 mmHg in her right and left eyes, respectively. Examination revealed edema of the eyelids and conjunctiva,and corneal fluorescence staining was positive. No inflammation in the anterior chamber or vitreous opacities were observed. Bilateral multiple retinal detachments were observed on the posterior fundus, and optical coherence tomography revealed bilateral multiple areas of retinal neuroepithelial detachment, choroidal thickening, and choroidal folds. No abnormal fluorescence leakage was observed on fundus fluorescein angiography or indocyanine green angiography. In addition, systematic manifestations included recurrent bilateral parotid gland enlargement. Labial gland biopsy revealed dilated glandular ducts, scattered interstitial glands, and lymphocytic foci. Salivary gland scintigraphy revealed severe impairment of glandular excretory function. Moreover, blood tests for anti-Ro/SSA and anti-La/SSBantibodies were positive. The patient was diagnosed with primary Sjögren's syndrome. After 2 months treatment with oral prednisolone acetate combined with hydroxychloroquine, her BCVAimproved to 0.8 and 1.0 in the right and left eyes, respectively. The fundus also recovered to normal, and no recurrence was observed during the 1-year follow-up period., Conclusions: The current case highlights that pSS, which usually manifests with dry eye and keratoconjunctivitis, may manifest with chronic choroiditis in both eyes as well. Based on our experience with this case, patients with clinically suspected bilateral choroiditis should be evaluated for pSS.

Background: Tubulointerstitial nephritis and uveitis (TINU) syndrome is an uveits characterized by complications of idiopathic acute tubulointerstitial nephritis, and most cases present only anterior uveitis. We report a case of TINU syndrome in which the presence of choroiditis was revealed by multimodal imaging., Case Presentation: A 12-year-old male visited our hospital with a 6-day history of ocular pain and hyperemia. Conjunctival and ciliary injections, 1 + flare and 3 + cells of anterior chamber inflammation with mutton fat keratic precipitates were observed in both eyes (OU), together with redness and swelling of the optic disc OU. Laboratory tests showed slightly high levels of soluble IL-2R and serum β2 microglobulin and markedly high levels of urinary β2 microglobulin. The diagnosis of probable TINU syndrome was established on the basis of bilateral uveitis and urinalysis results in accordance with a clinical criteria of tubulointerstitial nephritis. With treatment with oral prednisolone (PSL) at 20 mg/day, ocular findings improved, and the dose of PSL was gradually reduced and withdrawn 6 months later. However, 1 month later from the withdrawal, ocular inflammation recurred with the presence of retinal exudates and snowball vitreous opacities in the peripheral retina OU. Fluorescein angiography showed leakages from peripheral retinal vessels and staining corresponding to retinal exudates. Indocyanine green angiography showed hypofluorescent dots scattered over the ocular fundus. Optical coherence tomography revealed the presence of choroidal thickening. Laser speckle flowgraphy color map showed a relatively cooler color. Findings from these multimodal images indicated the presence of subclinical choroiditis; therefore, oral PSL was administered again, and ocular inflammatory findings were improved., Conclusions: TINU syndrome can exhibit subclinical choroiditis detected with multimodal imaging. Further studies are necessary to determine the frequency of subclinical choroiditis in TINU syndrome., (© 2023. BioMed Central Ltd., part of Springer Nature.)

We report a case of human herpes virus 6 (HHV-6)- and human herpes virus 7 (HHV-7)-associated choroiditis in an immunocompromised woman. A 42-year-old Chinese woman with a history of acute myelogenous leukemia presented with blurred vision and black floaters in her right eye. Anterior segment examination findings were normal. Ophthalmoscopic examination revealed a subretinal lesion in the superonasal peripapillary region with several punctate hemorrhages. Optical coherence tomography showed a crater-like choroidal protuberance, associated with retinal pigment epithelium rupture and full-thickness retinal edema in the involved area. Indocyanine green angiography demonstrated a broad hypofluorescent lesion in the choroid. The patient was diagnosed with choroiditis. Subsequently, metagenomic next-generation sequencing revealed HHV-6B and HHV-7 DNA in the aqueous humor. Therefore, antiviral therapy was initiated. The patient experienced resolution of all symptoms and signs after treatment with intravenous foscarnet and oral acyclovir. The findings in this case indicate that HHV-6 and HHV-7 can cause ocular infection, particularly in immunocompromised patients., Competing Interests: Declaration of conflicting interestsThe authors declare that there is no conflict of interest.

Background: Common variable immunodeficiency (CVID) has been recognised as the most common primary immunodeficiency in adulthood, and is characterised by increased susceptibility to infection, autoimmunity and increased risk of malignancies. Although ocular manifestations are not common in CVID, rare associated inflammatory eye conditions have been reported including submacular choroiditis., Objective: To report a case of punctate inner choroidopathy in a patient with common variable immunodeficiency., Case Presentation: A 40-year-old lady with CVID and associated autoimmune thrombocytopenia, who was treated with immunoglobulin replacement and Eltrombopag, experienced gradually deteriorating right eye vision. Fundal examination and optical coherence tomography (OCT) revealed right multifocal retinal choroidal lesions consistent with a diagnosis of unilateral punctate inner choroidopathy (PIC) with secondary choroidal neovascularisation (CNV). Anti-VEGF injections led to stabilised fundal appearances. Genetic testing revealed a heterozygous sequence change c.260 T > Ap.(IIe87Asn), pathogenic variant in the Tumour Necrosis Factor Superfamily 13B (TNFRSF13B) gene, which is reported as being associated with ∼10% of CVID cases., Conclusion: Autoimmunity may be the dominant clinical presenting feature of CVID. Punctuate inner choroidopathy is an idiopathic inflammatory chorioretinopathy, and to the best of our knowledge, has not been previously reported in CVID. A better understanding of the molecular bases of autoimmune diseases in CVID may provide novel therapeutic targets for autoimmune diseases in this patient population., (Copyright © 2023 Elsevier Inc.

Importance: Idiopathic multifocal choroiditis (MFC) is poorly understood, thereby hindering optimal treatment and monitoring of patients., Objective: To identify the genes and pathways associated with idiopathic MFC., Design, Setting, and Participants: This was a case-control genome-wide association study (GWAS) and protein study of blood plasma samples conducted from March 2006 to February 2022. This was a multicenter study involving 6 Dutch universities. Participants were grouped into 2 cohorts: cohort 1 consisted of Dutch patients with idiopathic MFC and controls, and cohort 2 consisted of patients with MFC and controls. Plasma samples from patients with idiopathic MFC who had not received treatment were subjected to targeted proteomics. Idiopathic MFC was diagnosed according to the Standardization of Uveitis Nomenclature (SUN) Working Group guidelines for punctate inner choroidopathy and multifocal choroiditis with panuveitis. Data were analyzed from July 2021 to October 2022., Main Outcomes and Measures: Genetic variants associated with idiopathic MFC and risk variants associated with plasma protein concentrations in patients., Results: This study included a total of 4437 participants in cohort 1 (170 [3.8%] Dutch patients with idiopathic MFC and 4267 [96.2%] controls; mean [SD] age, 55 [18] years; 2443 female [55%]) and 1344 participants in cohort 2 (52 [3.9%] patients with MFC and 1292 [96.1%] controls; 737 male [55%]). The primary GWAS association mapped to the CFH gene with genome-wide significance (lead variant the A allele of rs7535263; odds ratio [OR], 0.52; 95% CI, 0.41-0.64; P = 9.3 × 10-9). There was no genome-wide significant association with classical human leukocyte antigen (HLA) alleles (lead classical allele, HLA-A*31:01; P = .002). The association with rs7535263 showed consistent direction of effect in an independent cohort of 52 cases and 1292 control samples (combined meta-analysis OR, 0.58; 95% CI, 0.38-0.77; P = 3.0 × 10-8). In proteomic analysis of 87 patients, the risk allele G of rs7535263 in the CFH gene was strongly associated with increased plasma concentrations of factor H-related (FHR) proteins (eg, FHR-2, likelihood ratio test, adjusted P = 1.1 × 10-3) and proteins involved in platelet activation and the complement cascade., Conclusions and Relevance: Results suggest that CFH gene variants increase systemic concentrations of key factors of the complement and coagulation cascades, thereby conferring susceptibility to idiopathic MFC. These findings suggest that the complement and coagulation pathways may be key targets for the treatment of idiopathic MFC.

Purpose: To identify characteristics on multimodal imaging (MMI) in idiopathic multifocal choroiditis (MFC) that can identify inflammatory activity and distinguish choroidal neovascularization (CNV) activity from inflammatory activity., Design: Prospective cohort study., Methods: MMI consisted of spectral-domain optical coherence tomography (angiography) (SD-OCT(A)), fundus autofluorescence, fundus photography, infrared imaging, fluorescein angiography (FA), and indocyanine green angiography (ICGA). MMI characteristics obtained during active and inactive disease were compared within the same lesion. Secondly, MMI characteristics were compared between active inflammatory lesions with and without CNV activity., Results: Fifty patients (110 lesions) were included. In 96 lesions without CNV activity, the mean focal choroidal thickness was increased during the active disease (205 µm) compared to the inactive disease (180 µm) (P ≤ .001). Lesions with inflammatory activity typically demonstrated moderately reflective material located in the sub-retinal pigment epithelium (RPE) and/or in the outer retina with disruption of the ellipsoid zone. During the inactive stage of the disease, the material disappeared or became hyperreflective and indistinguishable from the RPE. During the active stage of the disease, the area of hypoperfusion in the choriocapillaris significantly increased as visualized on both ICGA and SD-OCTA. CNV activity in 14 lesions was associated with subretinal material with a mixed reflectivity and hypotransmission of light to the choroid on SD-OCT and leakage on FA. SD-OCTA identified vascular structures in all active CNV lesions and in 24% of lesions without CNV activity (showing old, quiescent CNV membranes)., Conclusion: Inflammatory activity in idiopathic MFC was associated with several MMI characteristics, including focally increased choroidal thickness. These characteristics can guide clinicians in the challenging process of the evaluation of disease activity in idiopathic MFC patients., (Copyright © 2023 The Authors. Published by Elsevier Inc.

Purpose: To describe the clinical characteristics and multimodal imaging features of a distinctive subtype of active idiopathic multifocal choroiditis (iMFC) lesions with grey-yellow chorioretinal lesions surrounded by smaller satellite dots, a presentation referred to as "chrysanthemum lesions.", Methods: Retrospective, observational, multicenter case series of eyes with active iMFC and chrysanthemum lesions. Multimodal imaging features were reviewed and presented., Results: Twenty-five eyes from 20 patients (12 women and 8 men), with a mean age of 35.8 ± 17.0 years (range, 7-78 years) were included. Chrysanthemum lesions were equally located in the macula (48.0%) or the mid/far periphery (52.0%). The number of lesions per eye varied from 1 (16.0%) to more than 20 (56.0%). On optical coherence tomography, chrysanthemum lesions showed typical features of iMFC, including subretinal hyperreflective material splitting the retinal pigment epithelium/Bruch membrane. Chrysanthemum lesions were hypoautofluorescent on fundus autofluorescence imaging, hyperfluorescent on fluorescein angiography, hypofluorescent on indocyanine green angiography, and associated with choriocapillaris flow signal deficit on optical coherence tomography angiography., Conclusion: Active iMFC may present with findings resembling chrysanthemum lesions. The distinctive lesion morphology on ophthalmoscopic examination, the large number of lesions, and the high prevalence of exclusive midperipheral and far peripheral involvement may represent a distinctive phenotype of iMFC.

Purpose: To present and compare the clinical features and multimodal imaging (MMI) findings of the primary form of multiple evanescent white dot syndrome (MEWDS) and MEWDS secondary to multifocal choroiditis/punctate inner choroidopathy (MFC/PIC)., Methods: A prospective case series. Thirty eyes of 30 MEWDS patients were included and divided into the primary MEWDS group and MEWDS secondary to MFC/PIC group. Demographic, epidemiologic, and clinical characteristics and MEWDS-related MMI findings of the two groups were compared., Results: Seventeen eyes from 17 patients with primary MEWDS and 13 eyes from 13 patients with MEWDS secondary to MFC/PIC were evaluated. Patients with MEWDS secondary to MFC/PIC tended to have a higher degree of myopia than those with primary MEWDS. No other significant differences in demographic, epidemiologic, and clinical characteristics and MMI findings were found between the two groups., Conclusion: "MEWDS-like reaction" hypothesis seems to be correct for MEWDS secondary to MFC/PIC, and the authors highlight the importance of MMI examinations in MEWDS. Further research is needed to confirm whether the hypothesis is applicable to other forms of secondary MEWDS.

Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE) and serpiginous choroiditis are two diseases classified as "white spot syndromes." Both are inflammatory/autoimmune diseases with suspected primary involvement of the choriocapillaris. The former usually has an excellent prognosis, while the latter can rapidly induce legal blindness. Whereas these diseases are well defined and well known, other entities (such as persistent placoid maculopathy or ampiginous choroiditis) with features of both APMPPE and serpiginous choroiditis have been described more recently. This review aims to describe demographic characteristics and multimodal imaging features to help differentiate between these four diseases., (Copyright © 2023 Elsevier Masson SAS.

Purpose: To evaluate choroidal lesions with spectral domain optical coherence tomography (SD-OCT) scan in varicella zoster virus (VZV) uveitis., Methods: VZV-uveitis cases which underwent OCT scan for choroidal lesions were studied. SD-OCT scan passing through these lesions was studied in detail. Subfoveal choroidal thickness (SFCT) during active and resolved stages was studied. Angiogaphic features were studied where available., Results: Thirteen out of 15 cases had same-sided herpes zoster ophthalmicus skin rashes. All except three patients had old or active kerato-uveitis. All eyes demonstrated clear vitreous and a single or multiple hypopigmented orangish-yellow choroidal lesions. The number of lesions remained unchanged during the follow-up on clinical examination. SD-OCT over lesions (n = 11) showed choroidal thinning (n = 5), hyporeflective choroidal elevation during active inflammation (n = 3), transmission effects (n = 4), and ellipsoid zone disruption (n = 7). The mean change in SFCT (n = 9) after resolution of the inflammation was 26.3 μm (range: 3-90 μm). Fundus fluorescein angiography showed iso-fluorescence over lesions in all (n = 5), but indocyanine green angiography (n = 3) showed hypofluorescence at lesions. Mean follow-up was 1.38 years (range: 3 months-7 years). De-novo appearance of choroidal lesion during the first relapse of VZV-uveitis was captured in one case., Conclusion: VZV-uveitis can cause focal or multifocal hypopigmented choroidal lesions with thickening or scarring of choroidal tissue, depending on the disease activity., Competing Interests: None

Purpose: To report recurrence of tubercular choroiditis following anti-SARS-CoV-2 vaccination in two patients with quiescent disease activity for more than a year., Methods: Retrospective observational case reports., Results: Two patients (one female and one male) under follow-up for posterior uveitis having stable course with absence of ocular inflammation for more than a year presented with recurrence of choroiditis lesions 2-6 weeks following anti-SARS-CoV-2 vaccination. Both the patients were managed with intravitreal dexamethasone implant (Ozurdex®, Allergan, Inc., Irvine, CA, USA) and showed resolution of choroiditis lesions upon follow-up., Conclusions: Acute onset recurrence of inflammation, in absence of any change in health status or treatment suggests the potential role of vaccination being the trigger of this reactivation. Given large-scale vaccination against novel coronavirus- SARS-CoV-2, careful vigilance is warranted to pick up the disease recurrence in patients with posterior uveitis.

Introduction: Ampiginous Choroiditis is a rare posterior uveitis that combines clinical features of Acute Multifocal Posterior Placoid Pigment Epitheliopathy and Serpiginous Chorioretinitis. Its pathophysiology is poorly understood and further studies are necessary to understand which mechanisms start the immunologic reaction., Case Report: The purpose of this article is to report a well-documented case of Ampiginous Choroiditis following in seven days a RT-PCR confirmed SARS-CoV-2 infection, suggesting that the infection might have contributed as a trigger., Conclusion: Timely diagnosis and correct treatment are paramount to improve the visual outcomes, and the patient had successful response to systemic steroids.

The diagnosis of OTB (Ocular tuberculosis) is usually difficult to make. Definitive diagnosis requires the identification of M. tuberculosis organisms in ocular tissues or fluids, but samples are often difficult to obtain, and biopsy may be hard to justify. We describe a 50-years-old Maghreb male, who presented a multifocal choroiditis associated with a choroidal tuberculoma on the left eye. Based on positive QuantiFERON-TB-Gold test and suggestive clinical and radiographic findings, a diagnosis of presumed ocular tuberculosis was made. Serial swept-source optical coherence tomography (SS-OCT) and widefield fundus retinographies during subsequent follow-up visits demonstrated the characterization of the atypical tuberculosis presentation and allowed the assessment of response to antitubercular therapy and oral steroids.

Purpose: To describe and analyze clinical characteristics of multifocal choroiditis with linear streaks (LSs)., Methods: Eight cases of multifocal choroiditis with LSs were retrospectively studied. Multimodal imaging was performed. Demographic data and spherical equivalent were collected. Axial length was measured., Results: All cases are young myopic women with a mean age of 17.13 ± 3.64 years (range, 13-23 years), presenting with vision loss and distortion. Nine eyes with LSs were high myopia of -8.97 ± 2.69 D (range, -6.00 to 12.5 D; growing by 1.88 ± 0.61 D annually since wearing glasses), with mean axial length of 26.36 ± 1.71 mm. Vitreous cells were noted in seven eyes. LSs were located in the equator (eight eyes), around the optic disk (three eyes), and at the edge of the posterior pole (one eye). Angio-optical coherence tomography showed choroidal neovascularization in eight eyes, especially 2 to 3 choroidal neovascularizations in three eyes. The location of choroidal neovascularization were in subfovea (three eyes), parafovea (six eyes), and perifovea (two eyes). Swept source optical coherence tomography showed punched-out disruption of retinal pigment epithelium‒Bruch's membrane‒choriocapillaris complex at the LSs' sites. LSs showed fluorescence staining on late FA but hypofluorescence throughout all phases on ICGA., Conclusion: Multifocal choroiditis with LSs mostly occurs in young women with high myopia, especially occurring in eyes with rapid progression of myopia. LSs are mainly located in the midperiphery near the equator, being prone to concur with choroidal neovascularization. Based on our findings, we propose a new term called "streaky multifocal choroiditis" as a subtype of multifocal choroiditis.

Purpose: To report a cohort of patients with a punctate inner choroidopathy (PIC)-like reaction in concurrent, unrelated, chorioretinal disorders., Methods: This was a retrospective observational study of patients seen at two referral centers with lesions consistent with PIC on multimodal imaging; patients with lesions resembling idiopathic multifocal choroiditis were also included. Active PIC-like lesions appeared as focal hyperreflective lesions splitting the retinal pigment epithelium/Bruch membrane (RPE/BrM) complex on optical coherence tomography. Chronic PIC-like lesions included subretinal fibrosis, multifocal punched-out chorioretinal atrophy, and curvilinear streaks. Patients' demographics, additional imaging features, and treatment responses were collected and summarized., Results: Twenty-two eyes of 16 patients with a PIC-like reaction were included (75% females; median age 40 years). Underlying diagnoses included hereditary retinal conditions (10 patients, 63%) and acquired etiologies, all characterized by the RPE/BrM or outer retinal disruption. Fifteen eyes (68%) had active PIC-like lesions; seven eyes (32%) had chronic PIC-like lesions. Active PIC-like lesions regressed with time and responded to systemic steroids. Subretinal fibrosis (3 eyes, 20%), macular atrophy (3 eyes, 20%), and concomitant subretinal fibrosis and macular atrophy (5 eyes, 33%) developed on follow-up. Recurrences occurred in five eyes (23%)., Conclusion: RPE/BrM or outer retina disruption may trigger a PIC-like reaction in susceptible patients, presumably because of the loss of immune privilege. A PIC-like reaction may influence the clinical progression and the visual prognosis of the primary chorioretinal disease.

Purpose: To report nine cases of multifocal choroiditis with serpiginous-like peripapillary chorioretinal atrophy., Methods: A retrospective observational case series of eyes with multifocal choroiditis with serpiginous-like peripapillary chorioretinal atrophy. Multimodal imaging findings were reviewed and presented., Results: Fifteen eyes of 9 patients (6 women and 3 men), with a mean age of 48.1 years (median, 46 years; range, 23-74 years), presented with multifocal choroiditis serpiginous-like peripapillary chorioretinal atrophy. All 15 eyes presented with serpiginoid peripapillary changes and had discrete patches of atrophy or punched-out scars in the posterior pole or periphery. Eleven eyes (73.3%) had cone-shaped retinal pigment epithelium elevations on optical coherence tomography, 10 eyes (66.7%) had mild vitritis, and 4 eyes (26.7%) had peripheral curvilinear streak lesions. Three eyes (20%) had choroidal neovascularization. All patients responded well to treatment with systemic immunosuppression, local corticosteroid injections, and/or intravitreal anti-vascular endothelial growth factor injections., Conclusion: Multifocal choroiditis may present with peripapillary chorioretinal changes resembling a serpiginous-like choroiditis in addition to the classic findings of patches of atrophy or punched-out scars in the posterior pole or periphery, cone-shaped retinal pigment epithelium elevated on optical coherence tomography and peripheral curvilinear streak lesions.

Purpose: This study aims to evaluate the outcomes of adalimumab (ADA) therapy in patients with refractory punctate inner choroidopathy (PIC) and multifocal choroiditis (MFC)., Methods: Demographic and clinical data, including LogMAR best-corrected visual acuity (BCVA), were retrospectively collected. Doses of prednisone, immunomodulatory therapies (IMT), and anti-vascular endothelial growth factor (VEGF) injections before and after baseline (ADA initiation) were recorded, as well as the time to clinical remission, time to first flare, and drug-associated adverse events., Results: Seven patients (4 females, ten eyes) were included. The mean follow-up after baseline was 17.8 ± 11.1 months (range 6-33). The mean LogMAR BCVA was 0.35 ± 0.77 at 6 months before baseline and remained stable throughout 12 months after baseline (0.31 ± 0.46 at 12 months; p = 0.47). The mean dose of prednisone decreased from 17.3 ± 19.6 mg/day 6 months before baseline (range 0-60) to 2.6 ± 2.4 mg/day at the last follow-up (range 0-6, p = 0.03). The mean number of flares decreased significantly from 1.43 ± 0.79 over a 6-month period before baseline to 0.2 ± 0.45 (p = 0.02) at 6-12 months after baseline. The mean number of anti-VEGF injections was 4.17 ± 3.92 over the 12-month period before baseline, and it was 2.17 ± 3.06 (p = 0.31) during the first 12 months after baseline. No adalimumab-related adverse events were noted., Conclusion: Adalimumab therapy for refractory PIC/MFC enabled a significant steroid-sparing effect, decreased disease flares, and preserved vision over a mean follow-up of 17.8 months., (© 2022.

Purpose: To assess the ability of wide field Swept Source OCTA (SS-OCTA) imaging to detect morphological variations in Serpiginous Choroiditis (SC) and Serpiginous Like Choroiditis (SLC) in response to treatment and also analyze these findings quantitatively using Image J software., Methods: Retrospective observational case series of nine eyes with clinical diagnosis of active SC and SLC, who underwent SS-OCTA and fundus autofluorescence (FAF) imaging at baseline and each follow up visit till 6 months. Morphological analysis was done by two independent graders and quantitative analysis to measure the size and intensity of lesion was done using publicly available Image J software at baseline and each follow up visit., Design: Retrospective observational case series., Results: Using SS-OCTA, all the active lesions followed a characteristic healing pattern. Active lesions appear well defined hypo flow void patches and as healing progressed, lesion became more ill-defined and iso-hyper- intense. Significant increase in mean intensity of the lesion could be apparent after 1 and 6 month of treatment. There was reduction in the size of lesions during follow up however this difference was not statistically significant., Conclusion: SS-OCTA could be a useful noninvasive tool to study the treatment response in SC/SLC both morphologically as well as quantitatively. Quantitative parameters need to be designed in further research studies to aid in uniform management and follow up of uveitis cases.

To develop and evaluate a fully automated pipeline that analyzes color fundus images in patients with tubercular serpiginous-like choroiditis (TB SLC) for prediction of paradoxical worsening (PW). In this retrospective study, patients with TB SLC with a follow-up of 9 months after initiation of anti-tubercular therapy were included. A fully automated custom-designed pipeline was developed which was initially tested using 12 baseline color fundus photographs for assessment of repeatability. After confirming reliability using Bland-Altman plots and intraclass correlation coefficient (ICC), the pipeline was deployed for all patients. The images were preprocessed to exclude the optic nerve from the fundus photo using a single-shot trainable WEKA segmentation algorithm. Two automatic thresholding algorithms were applied, and quantitative metrics were generated. These metrics were compared between PW + and PW- groups using non-parametric tests. A logistic regression model was used to predict probability of PW for assessing binary classification performance and receiver operator curves were generated to choose a sensitivity-optimized threshold. The study included 139 patients (139 eyes; 92 males and 47 females; mean age: 44.8 ± 11.3 years) with TB SLC. Pilot analysis of 12 images showed an excellent ICC for measuring the mean area, intensity, and integrated pixel intensity (all ICC > 0.89). The PW + group had significantly higher mean lesion area (p = 0.0152), mean pixel intensity (p = 0.0181), and integrated pixel intensity (p < 0.0001) compared to the PW- group. Using a sensitivity optimized threshold cut-off for mean pixel intensity, an area under the curve of 0.87 was achieved (sensitivity: 96.80% and specificity: 72.09%). Automated calculation of lesion metrics such as mean pixel intensity and segmented area in TB SLC is a novel approach with good repeatability in predicting PW during the follow-up., (© 2022.

Objective: To provide a complete picture and to improve understanding of the serpiginous-like choroiditis caused by Mycobacterium Tuberculosis., Materials and Methods: Literature review of serpiginous-like choroiditis. A number of scientific search engines were searched including Medline (PubMed), Scielo, and Cochrane Library. Using MeSH and DeCS terms., Results: 107 articles were obtained, of which 44 met inclusion criteria., Discussion: serpiginous-like choroiditis is described as its etiology, pathogenesis, ocular findings, diagnosis, differential diagnosis and treatment., Conclusions: Modern studies are needed to understand the pathophysiology, new diagnostic strategies, and future treatments of serpiginous-like choroiditis, (Universidad Nacional de Córdoba)

Objective: To assess the reliability and validity of gray level co-occurrence matrices (GLCM) in the quantification of choriocapillaris and describe GLCM features in normal and eyes with resolved acute posterior multifocal placoid pigment epitheliopathy (APMPPE) and serpiginous choroiditis (SC)., Methods: In this, multicenter, reliability, validity and comparative study; OCTA was performed on eyes with resolved APMPPE and SC and normal individuals. CC texture classification, low flow area measurements and GLCM feature extraction were performed., Results: A total of 13 normal, 8 APMPPE and 15 SC eyes were analyzed. All GLCM parameters demonstrated an excellent reliability. GLCM parameters were differently distributed across the three groups. Decision-tree based on the random forest predictive model provided an overall accuracy of 86% in classifying the three groups using GLCM features., Conclusion: These data demonstrated an excellent reliability and validity of GLCM features in quantifying the choriocapillaris in healthy and diseased eyes.

Purpose: To describe the application of OCT-A in various posterior uveitis disorders in our experience and to compare it with the available literature., Methods: Eighteen eyes with the diagnoses of multifocal choroiditis (MFC), multifocal placoid pigment epitheliopathy (APMPPE), multiple evanescent white dot syndrome (MEWDS), tuberculous serpiginous-like choroiditis (SLC), serpiginous choroiditis (SC), and birdshot chorioretinopathy (BSCR) were studied., Results: We found flow void of the choriocapillaris in patients with APMPPE, SC, MFC, BSCR, and in SLC. In contrast, perfusion of the choriocapillaris seemed normal in patients with MEWDS., Conclusions: We confirmed that OCT-A contributes new information on the physiopathology of white dot syndromes and inflammatory chorioretinopathies, notably on whether or not the choriocapillaris is involved. Comparing the OCT-A features allowed us to suggest that both APMPPE and SLC might be part of the same spectrum of inflammatory disease with primary involvement at the level of the choriocapillaris and secondary RPE damage.

Purpose: To analyze distribution and progression of multifocal choroiditis (MFC) inflammatory lesions and their correlations with clinical outcomes at 24 months., Methods: Distribution and progression of inflammatory lesions were evaluated in eyes with MFC using a semi-automatic approach based on fundus autofluorescence. Twenty-four-months clinical outcomes were correlated with baseline features., Results: Twenty-five eyes from 20 patients were enrolled. Visual acuity (VA) significantly improved from baseline to 24 months. Chorioretinal lesions spared the fovea in most eyes. The area of inflammatory lesions at 24 months significantly increased. Final number and area of lesions were significantly influenced by baseline features. Inflammatory lesions enlarged over time regardless of MFC recurrences. New lesion and MFC relapses did not affect final outcomes., Conclusions: Final VA correlated with baseline VA. Scars resulting from MFC lesions enlarged overtime even when the disease was under control. New lesions and MFC relapses did not affect final outcomes.

Purpose: A heatmap analysis of choroidal lesions in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) with or without uveitis was performed to determine if there were any distinguishing features among these uveitic entities., Methods: Retrospective review of medical records was conducted at the Byers Eye Institute, Stanford. Fundus photographs were masked and placed on a standardized template. Lesions were identified and heatmaps were generated in a standardized fashion., Results: 30 eyes were identified with PIC or MFC. Heatmap analysis revealed three distinct patterns of fundus lesions: posterior, peripheral, and combined. All patients with PIC had the posterior pattern. Patients with MFC had the peripheral or combined pattern, and all patients with MFC with uveitis had the combined pattern., Conclusion: Three patterns of fundus lesions were identified in patients with PIC and MFC. PIC and MFC may represent two separate disease entities with distinct phenotypes of choroidal lesions.
