Long-Term Clinical Outcomes of the 0.18 Mg Fluocinolone Acetonide Intravitreal Implant Following Local Corticosteroid Burst in Noninfectious Uveitis.

PURPOSE: The 0.18 mg fluocinolone acetonide implant (FAi) is marketed for up to 36 months for treatment of noninfectious uveitis. An additional short-term corticosteroid burst prior to the 0.18 mg FAi, followed by attempt at long-term inflammation control with the 0.18 mg FAi may be beneficial given the low dose of the implant. We retrospectively reviewed all patients undergoing this treatment approach at our institution to determine its efficacy. METHODS: Patients who received a corticosteroid burst followed by the 0.18 mg FAi with at least 6-month follow-up post 0.18 mg FAi were included. The primary outcome, treatment escalation (defined as worsening inflammation requiring escalation of therapy), was modeled using Kaplan-Meier analysis. Secondary outcomes included cystoid macular edema (CME), central macular thickness, retinal vasculitis, visual acuity, anterior chamber and vitreous cell, use of systemic therapy, use of corticosteroid drops, IOP, number of IOP lowering medications, need for glaucoma surgery, need for cataract surgery, and additional local corticosteroids. RESULTS: 32 eyes were included (mean follow-up: 19.8 months). Prior to corticosteroid burst, 37.5% were on systemic therapy, 53% had CME, and 25% had retinal vasculitis. At FAi visit, CME had decreased to 18.8%. Mean time to treatment escalation after FAi was 20.3 months (95% CI 14.8-25.7 months). No patient discontinued systemic therapy and on average 15.0% of eyes required additional local corticosteroids at each follow-up interval. CONCLUSIONS: This treatment approach demonstrates that the 0.18 mg FAi is a useful adjuvant for the treatment of noninfectious uveitis but may not be adequate as solo therapy.

Optic Disc Edema Is an Under-Recognized Feature of Birdshot Chorioretinitis.

BACKGROUND: Optic disc edema is a feature of many ophthalmic and neurologic conditions. It remains an underappreciated feature of birdshot chorioretinitis (BSCR), leading to delay in diagnosis and treatment. The purpose of our study was to identify clinical features that are concomitant with optic disc edema and suggest a diagnosis of BSCR. METHODS: Retrospective multicenter case series of 29 patients who were referred to a neuro-ophthalmologist or uveitis specialist for evaluation of disc edema and were ultimately diagnosed with BSCR. RESULTS: Fifty-four eyes of 30 patients, from the practices of 15 uveitis specialists, met the eligibility criteria. In addition to disc edema, concomitant features in all patients included vitritis, chorioretinal lesions, and retinal vasculitis. Visual recovery to 20/40 or better occurred in 26 of 29 patients. Visual acuity remained 20/100 or worse in 2 patients previously diagnosed with idiopathic intracranial hypertension, 1 patient previously diagnosed with optic neuritis, and 1 patient for whom treatment was delayed for years, leading to optic disc atrophy. CONCLUSIONS: Optic disc edema is a presenting feature in some cases of BSCR. A diagnosis of BSCR should be considered when disc edema occurs with vitritis, chorioretinal inflammation, and retinal vasculitis. Patients should be referred to a uveitis specialist for treatment.

The Infectious Uveitis Treatment Algorithm Network (TITAN) Report 1-global current practice patterns for the management of Herpes Simplex Virus and Varicella Zoster Virus anterior uveitis.

AIMS: To present current expert practice patterns and to formulate a consensus for the management of HSV and VZV AU by uveitis specialists worldwide. METHODS: A two-round online modified Delphi survey with masking of the study team was conducted. Responses were collected from 76 international uveitis experts from 21 countries. Current practices in the diagnosis and treatment of HSV and VZV AU were identified. A working group (The Infectious Uveitis Treatment Algorithm Network [TITAN]) developed data into consensus guidelines. Consensus is defined as a particular response towards a specific question meeting ≥75% of agreement or IQR ≤ 1 when a Likert scale is used. RESULTS: Unilaterality, increased intraocular pressure (IOP), decreased corneal sensation and diffuse or sectoral iris atrophy are quite specific for HSV or VZV AU from consensus opinion. Sectoral iris atrophy is characteristic of HSV AU. Treatment initiation is highly variable, but most experts preferred valacyclovir owing to simpler dosing. Topical corticosteroids and beta-blockers should be used if necessary. Resolution of inflammation and normalisation of IOP are clinical endpoints. CONCLUSIONS: Consensus was reached on several aspects of diagnosis, choice of initial treatment, and treatment endpoints for HSV and VZV AU. Treatment duration and management of recurrences varied between experts.

The Infectious Uveitis Treatment Algorithm Network (TITAN) Report 2-global current practice patterns for the management of Cytomegalovirus anterior uveitis.

AIMS: To present current practice patterns in the diagnosis and management of Cytomegalovirus anterior uveitis (CMV AU) by uveitis experts worldwide. METHODS: A two-round modified Delphi survey with masking of the study team was performed. Based on experience and expertise, 100 international uveitis specialists from 21 countries were invited to participate in the survey. Variation in the diagnostic approaches and preferred management of CMV AU was captured using an online survey platform. RESULTS: Seventy-five experts completed both surveys. Fifty-five of the 75 experts (73.3%) would always perform diagnostic aqueous tap in suspected CMV AU cases. Consensus was achieved for starting topical antiviral treatment (85% of experts). About half of the experts (48%) would only commence systemic antiviral treatment for severe, prolonged, or atypical presentation. The preferred specific route was ganciclovir gel 0.15% for topical treatment (selected by 70% of experts) and oral valganciclovir for systemic treatment (78% of experts). The majority of experts (77%) would commence treatment with topical corticosteroid four times daily for one to two weeks along with antiviral coverage, with subsequent adjustment depending on the clinical response. Prednisolone acetate 1% was the drug of choice (opted by 70% of experts). Long-term maintenance treatment (up to 12 months) can be considered for chronic course of inflammation (88% of experts) and those with at least 2 episodes of CMV AU within a year (75-88% of experts). CONCLUSIONS: Preferred management practices for CMV AU vary widely. Further research is necessary to refine diagnosis and management and provide higher-level evidence.

The Humira in Ocular Inflammations Taper (HOT) Study.

PURPOSE: To assess factors that impact the risk of relapse in patients with noninfectious uveitis (NIU) who undergo adalimumab tapering after achieving remission. DESIGN: Retrospective study. METHODS: In this multicenter study, patients with NIU were treated with adalimumab and subsequently tapered. Patient demographics, type of NIU, onset and duration of disease, the period of inactivity before tapering adalimumab, and the tapering schedule were collected. The primary outcome measures were independent predictors of the rate of uveitis recurrence after adalimumab tapering. RESULTS: Three hundred twenty-eight patients were included (54.6% female) with a mean age of 34.3 years. The mean time between disease onset and initiation of adalimumab therapy was 35.2 ± 70.1 weeks. Adalimumab tapering was commenced after a mean of 100.8 ± 69.7 weeks of inactivity. Recurrence was observed in 39.6% of patients at a mean of 44.7 ± 61.7 weeks. Patients who experienced recurrence were significantly younger than those without recurrence (mean 29.4 years vs 37.5 years, P = .0005), and the rate of recurrence was significantly higher in younger subjects (hazard ratio [HR] = 0.88 per decade of increasing age, P = .01). The lowest rate of recurrence was among Asian subjects. A faster adalimumab taper was associated with an increased recurrence rate (HR = 1.23 per unit increase in speed, P < .0005). Conversely, a more extended period of remission before tapering was associated with a lower rate of recurrence (HR = 0.97 per 10-weeks longer period of inactivity, P = .04). CONCLUSIONS: When tapering adalimumab, factors that should be considered include patient age, race, and duration of disease remission on adalimumab. A slow tapering schedule is advisable.

Tubulointerstitial Nephritis and Uveitis Syndrome in Pediatric Patients.

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a disorder that was originally described in 1975. The syndrome, although diagnosed in all age ranges, is more frequently reported in pediatric patients. Diagnosis can be difficult, and its clinical spectrum is still being defined. In this article, we review the epidemiology, diagnosis, pathogenesis, clinical findings, prognosis, and treatment of both the ocular and renal disease. We comment on the current difficulties in diagnosis and study of the disease, its expanding clinical spectrum, and treatment strategies in pediatric patients.

MULTIZONAL OUTER RETINOPATHY AND RETINAL PIGMENT EPITHELIOPATHY (MORR): A Newly Recognized Entity or an Unusual Variant of AZOOR?

PURPOSE: To describe specific clinical, multimodal imaging, and natural history features of an unusual variant of acute zonal occult outer retinopathy. METHODS: Retrospective, observational, longitudinal, multicenter case series. Patients exhibiting this unusual clinical condition among cases previously diagnosed with acute zonal occult outer retinopathy were included. Multimodal imaging, laboratory evaluations, and genetic testing for inherited retinal diseases were reviewed. RESULTS: Twenty eyes from 10 patients (8 females and 2 males) with a mean age of 54.1 ± 13.3 years (range, 38-71 years) were included. The mean follow-up duration was 13.1 ± 5.3 years (range, 8-23 years). Presenting symptoms were bilateral in 7 patients (85% of eyes) and included scotomata and photopsia. All patients had bilateral lesions at presentation involving the peripapillary and far peripheral retina. Baseline optical coherence tomography showed alteration of the retinal pigment epithelium and photoreceptor layers corresponding to zonal areas of fundus autofluorescence abnormalities. Centrifugal and centripetal progression of the peripapillary and far-peripheral lesions, respectively, occurred over the follow-up, resulting in areas of complete outer retinal and retinal pigment epithelium atrophy. CONCLUSION: Initial alteration of photoreceptors and retinal pigment epithelium and a stereotypical natural course that includes involvement of the far retinal periphery, characterize this unusual condition. It may represent a variant of acute zonal occult outer retinopathy or may be a new entity. We suggest to call it multizonal outer retinopathy and retinal pigment epitheliopathy .

Multimodal imaging of an acute presentation of ocular histoplasmosis syndrome in an immunocompetent patient.

Purpose: Presumed ocular histoplasmosis syndrome (POHS) is a posterior segment disorder that is usually subclinical unless choroidal neovascular membrane (CNVM) develops. It is thought to be the sequela of a prior systemic infection with Histoplasma capsulatum, and evidence supporting this association is based on epidemiologic, animal, and few enucleation studies. Acute presentation of chorioretinal involvement during an initial histoplasmosis systemic infection in immunocompetent patients is rarely reported, presumably due to the usual lack of or minimal symptoms of both the systemic and ocular disease. We report on an immunocompetent male with choroidal lesions detected during disseminated histoplasmosis infection and characterize the lesions using multimodal imaging. Observations: A 17-year-old male presented when routine optometry screening detected two deep, yellowish-white lesions in the left fundus. Optical coherence tomography (OCT) imaging confirmed a choroidal mass with extension through Bruch's membrane into the subretinal space and a small amount of subretinal fluid. Fluorescein angiography was suggestive of CNVM. There were no clinical findings of intraocular inflammation, and the patient was initially lost to follow-up. Eight weeks after last follow-up, the patient presented to the emergency department with fatigue, mild respiratory symptoms, and abdominal pain for the last month. Imaging revealed a mediastinal mass with hilar extension and innumerable nodules throughout the lung and spleen. Serum Histoplasma IgM/IgG were positive, and biopsy of the mediastinal mass revealed Histoplasma organisms. The patient was treated with antifungals and discharged. The patient underwent an extensive immunologic evaluation while admitted, which did not reveal an underlying immunodeficiency. On last follow-up, the choroidal lesions were smaller and more consolidated, and the subretinal fluid had resolved. Conclusions and Importance: We present a patient with choroidal lesions in the setting of disseminated systemic histoplasmosis infection and characterize a lesion using multimodal imaging. The presentation of acute chorioretinal lesions in the setting of biopsy proven systemic Histoplasma infection supports H. capsulatum as the etiology of POHS.

Efficacy of Biosimilar Infliximab-Dyyb in Non-Infectious Uveitis.

PURPOSE: To describe the frequency of uveitis recurrences in patients with non-infectious uveitis treated with the biosimilar infliximab-dyyb. DESIGN: Retrospective case series. METHODS: Records of uveitis patients treated with the biosimilar infliximab-dyyb between 2016 and 2022 at two institutions were reviewed. Data extracted included patient demographics, diagnosis, previous originator infliximab use, additional immunosuppression medications, infliximab-dyyb use, reason for switch, disease activity, and follow-up time. RESULTS: A total of 14 patients were identified. Seven patients were switched from originator infliximab to a biosimilar for nonmedical/non-ocular reasons (insurance prompted the switch). One patient was started directly on infliximab-dyyb due to active joint disease despite well-controlled uveitis. None of these eight patients developed inflammation after the switch. Six patients were started directly on infliximab-dyyb due to poorly controlled uveitis. Of these, five patients achieved disease quiescence during follow-up. The mean dose of originator was 1.79 mg/kg/week, with a median dosing schedule of 4 weeks prior to therapy with infliximab-dyyb. The mean final infliximab-dyyb dosage was 1.81 mg/kg/week, with a median dosing schedule of 4 weeks. CONCLUSION: Infliximab-dyyb appears to be efficacious in achieving and maintaining uveitis control.

Use of Immunosuppression and the Risk of Subsequent Overall or Cancer Mortality.

PURPOSE: To determine the incidence of all-cause and cancer mortality (CM) in association with immunosuppression. DESIGN: Retrospective cohort study at ocular inflammatory disease (OID) subspecialty centers. We harvested exposure and covariate data retrospectively from clinic inception (earliest in 1979) through 2010 inclusive. Then we ascertained overall and cancer-specific mortalities by National Death Index linkage. We constructed separate Cox models to evaluate overall and CM for each class of immunosuppressant and for each individual immunosuppressant compared with person-time unexposed to any immunosuppression. PARTICIPANTS: Patients with noninfectious OID, excluding those with human immunodeficiency infection or preexisting cancer. METHODS: Tumor necrosis factor (TNF) inhibitors (mostly infliximab, adalimumab, and etanercept); antimetabolites (methotrexate, mycophenolate mofetil, azathioprine); calcineurin inhibitors (cyclosporine); and alkylating agents (cyclophosphamide) were given when clinically indicated in this noninterventional cohort study. MAIN OUTCOME MEASURES: Overall mortality and CM. RESULTS: Over 187 151 person-years (median follow-up 10.0 years), during which 15 938 patients were at risk for mortality, we observed 1970 deaths, 435 due to cancer. Both patients unexposed to immunosuppressants (standardized mortality ratio [SMR] = 0.95, 95% confidence interval [CI], 0.90-1.01) and those exposed to immunosuppressants but free of systemic inflammatory diseases (SIDs) (SMR = 1.04, 95% CI, 0.95-1.14) had similar mortality risk to the US population. Comparing patients exposed to TNF inhibitors, antimetabolites, calcineurin inhibitors, and alkylating agents with patients not exposed to any of these, we found that overall mortality (adjusted hazard ratio [aHR] = 0.88, 0.89, 0.90, 1.11) and CM (aHR = 1.25, 0.89, 0.86, 1.23) were not significantly increased. These results were stable in sensitivity analyses whether excluding or including patients with SID, across 0-, 3-, or 5-year lags and across quartiles of immunosuppressant dose and duration. CONCLUSIONS: Our results, in a cohort where the indication for treatment was proven unassociated with mortality risk, found that commonly used immunosuppressants-especially the antimetabolites methotrexate, mycophenolate mofetil, and azathioprine; the TNF inhibitors adalimumab and infliximab, and cyclosporine-were not associated with increased overall and CM over a median cohort follow-up of 10.0 years. These results suggest the safety of these agents with respect to overall and CM for patients treated with immunosuppression for a wide range of inflammatory diseases.

Demystifying Ocular Syphilis - A Major Review.

Syphilis, caused by the spirochaete, Treponema pallidum, continues to be a public health challenge globally with its rates steadily increasing in the past few years. The disease is transmitted through small breaks in the skin during sexual contact, or via congenital transmission in utero, either across the placenta or by contact with an active genital lesion during delivery. Estimated 5.7-6 million new cases are detected every year worldwide in the 15-49 years age group. An increased incidence has been reported in most populations with particular clusters in special groups like men who have sex with men, female sex workers, and their male clients. Ocular syphilis has a varied presentation and is considered a great mimicker in all cases of uveitis. The laboratory diagnosis of syphilis is predominantly based on serological tests including TPHA and VDRL. Parenteral penicillin is the cornerstone of treatment for all stages of ocular syphilis.

Risk of failing both methotrexate and mycophenolate mofetil from the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial.

BACKGROUND: The antimetabolites methotrexate (MTX) and mycophenolate mofetil (MMF) are commonly used as initial corticosteroid-sparing treatment for uveitis. There is little data examining risk factors for failing both MTX and MMF. The objective of this study is to determine risk factors for failing both MTX and MMF in patients with non-infectious uveitis. MAIN BODY: This is a sub-analysis of the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial, which was an international, multicenter, block-randomized, observer-masked, comparative effectiveness trial comparing MTX and MMF as initial treatments for non-infectious uveitis. This study was undertaken at multiple referral centers in India, the United States, Australia, Saudi Arabia and Mexico between 2013 and 2017. A total of 137 patients who completed all 12 months of follow-up from the FAST trial, were included in this study. The primary outcome was failing both antimetabolites over the 12 months of the trial. Potential predictors included: age, sex, bilateral involvement, anatomic location of the uveitis, presence of cystoid macular edema (CME) and retinal vasculitis at baseline visit, uveitis duration, and country/study sites as risk factors for failing both MTX and MMF. The presence of retinal vasculitis posterior to the equator on fluorescein angiogram was associated with failing both MTX and MMF. CONCLUSION: Retinal vasculitis may be a risk factor for failing multiple antimetabolites. Clinicians could consider more quickly advancing these patients to other medication classes, such as biologics.

The Microbiome and Uveitis: A Narrative Review.

The human intestinal microbiome is composed of hundreds of species and has recently been recognized as an important source of immune homeostasis. While dysbiosis, an altered microbiome from the normal core microbiome, has been associated with both intestinal and extraintestinal autoimmune disorders, including uveitis, causality has been difficult to establish. There are four proposed mechanisms of how the gut microbiome may influence the development of uveitis: molecular mimicry, imbalance of regulatory and effector T cells, increased intestinal permeability, and loss of intestinal metabolites. This review summarizes current literature on both animal and human studies that establish the link between dysbiosis and the development of uveitis, as well as provides evidence for the above mechanisms. Current studies provide valuable mechanistic insights as well as identify potential therapeutic targets. However, study limitations and the wide variability in the intestinal microbiome among populations and diseases make a specific targeted therapy difficult to establish. Further longitudinal clinical studies are required to identify any potential therapeutic that targets the intestinal microbiome.

Relentless placoid chorioretinitis: A review of four cases in pediatric and young adult patients with a discussion of therapeutic strategies.

Introduction: Relentless placoid chorioretinitis (RPC) is a rare, bilateral disease of the retinal pigment epithelium. The clinical course is prolonged and relapsing. No standard treatment has been established to date. The purpose of this case series is to report four cases of RPC in pediatric and young adult patients in which varying treatments were used, comparing them to previously published cases. Methods: A literature review was conducted to investigate currently published presentations and treatment options for RPC. A multicenter retrospective chart review was also performed on four consecutive patients. These patients were diagnosed with RPC because of new chorioretinitis lesions continuing to appear without or despite therapy for 5-36 months (2 patients), with a clinical course prolonged and relapsing, or because of the atypical location of the multiple lesions (>50) extending from the posterior pole to the equator and mid-peripheral retina (all four patients), which were not consistent with other entities like acute posterior multifocal placoid pigment epitheliopathy and serpiginous choroiditis. Results: All four cases of RPC received oral or IV steroids acutely, and three of these patients were transitioned to a steroid-sparing agent and biologic therapy: anti-TNF alpha or anti-IL-6. Quiescence of the chorioretinitis lesions was obtained after 7 months, 1 month, and 36 months; however, the latter had issues with treatment adherence. Mycophenolate mofetil was insufficient to control the disease in one patient, but tocilizumab and infliximab thereafter were effective after cessation of adalimumab due to side effects. Adalimumab when started the first month after the presentation was effective in controlling the disease in one patient. After the failure of interferon-alpha-2a, one patient displayed long-term control with infliximab. One patient did not require a steroid-sparing agent after oral prednisone taper as there was no evidence of progression or recurrence. Conclusion: This case series adds to the current knowledge regarding potential treatments for RPC, specifically the use of anti-TNF-alpha treatment and anti-IL-6 tocilizumab. In this case study, relapses of RPC were found among patients on mycophenolate mofetil and interferon-alpha-2a, and one case did not relapse on oral steroids without a steroid-sparing agent. Our findings suggest that adalimumab, infliximab, and tocilizumab may be useful medications to obtain quiescence of RPC.

Do not discount the diagnosis of VKH based on race: self-reported race and ethnicity of patients with Vogt-Koyanagi-Harada disease in a predominantly white population.

BACKGROUND: We examined the racial and ethnic distribution of patients with Vogt-Koyanagi-Harada disease (VKH) in a Midwestern US population through a retrospective chart review of patients with VKH seen in a tertiary referral centre between 2012 and 2017. All patients were diagnosed by one uveitis specialist (DAG). We identified 32 patients with VKH seen during this time period. The mean age at diagnosis was 37.7 ± 15.7 years, 7 were male, 25 female. Mean follow-up was 36.7 ± 21.7 months. Nine patients reported themselves as White non-Hispanic, (28.1%), 9 as Black/African-American (28.1%), 2 as Asian (6.3%) and 9 as Hispanic or Latino (28.1%). Three patients (9.4%) were of Middle-Eastern origin. The 2010 census results for race and ethnicity in the state of Illinois were: 71.5% White, 14.5% Black/African-American, 4.6% Asian, and 6.7% as Some Other Race. From the total population 15.8% reported themselves as Hispanic or Latino (of any race). CONCLUSIONS: VKH was much more frequent among white non-Hispanic patients (28.1%) and Black/African-American patients (28.1%) in our patient population than in previous reports from the US (3-14% and 4-23% respectively). While Hispanic patients in this series were over represented in the VKH population compared with the overall census data, the percentage of VKH patients in this series who were White non-Hispanic and Hispanic was the same. The diagnosis of VKH should be considered in any patient with the appropriate clinical features, regardless of race or ethnicity.

Multiple Evanescent White-Dot Syndrome in a 9-Year-Old Girl.

Purpose: This work describes a case of multiple evanescent white-dot syndrome (MEWDS) in a 9-year-old girl. Methods: A case report is presented. Results: A case of MEWDS in a 9-year-old girl is described. Conclusions: To our knowledge this is the youngest presentation of MEWDS discussed in the literature. MEWDS should be considered in the differential diagnosis of ocular inflammation in the first decade of life.

Optical Coherence Tomography Anatomic and Temporal Biomarkers in Uveitic Macular Edema.

PURPOSE: To assess the relationship between best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) features in noninfectious uveitis (NIU)-related macular edema. DESIGN: Clinical cohort study from post hoc analysis of 2 phase 3 clinical trials. METHODS: Correlation and longitudinal treatment analyses were performed. Of 198 patients with NIU, 134 received suprachoroidal CLS-TA (proprietary formulation of a triamcinolone acetonide injectable suspension), and 64 received sham, with 12.9% and 72%, respectively, receiving rescue therapy. RESULTS: At baseline, mean BCVA progressively worsened with each ordinal drop in central subfield ellipsoid zone (EZ) integrity. Eyes with normal baseline EZ experienced greater 24-week change in BCVA versus those with some degree of baseline EZ disruption (11.9 vs 9.4 letters, P = .006). In contrast, eyes with baseline central subfield cystoid spaces and/or subretinal fluid showed more improvement (13.7 or 17.2 letters, respectively) at 24 weeks, versus those without such findings (5.5 [P = .012] or 9.5 letters [P < .001], respectively). Longitudinal modeling for CLS-TA-treated eyes showed that central subfield thickness (CST) reached 90% of maximal improvement by week 3, whereas 90% maximal response in BCVA was not reached until week 9. CLS-TA-treated eyes that showed CST reduction of ≥50 µm at 4 weeks experienced a greater 24-week improvement in BCVA versus those without such an early response (14.6 vs 6.5 letters, P = .006 for difference). CONCLUSIONS: Pretreatment EZ integrity and the presence of central subfield cystoid spaces or subretinal fluid each predict improved therapeutic response to treatment in eyes with NIU. In CLS-TA treated eyes, longitudinal modeling shows CST improvement preceding BCVA improvement.

Advanced OCT Analysis of Biopsy-proven Vitreoretinal Lymphoma.

PURPOSE: Although diagnosing vitreoretinal lymphoma (VRL) can be challenging, early detection is critical for visual prognosis. We analyzed the spectrum of optical coherence tomography (OCT) findings in patients with biopsy-proven VRL and correlate these features with clinical parameters. DESIGN: This retrospective cross-sectional study was a multicenter chart review from 13 retina, uveitis, and ocular oncology clinics worldwide from 2008 to 2019. We included patients with a diagnosis of biopsy-proven VRL imaged with OCT at presentation. Ocular information, systemic information, and multimodal retinal imaging findings were collected and studied. The main outcome measure was the characteristics of VRL on OCT. RESULTS: A total of 182 eyes of 115 patients (63 women, mean age 65 years) were included in this study. The disease was bilateral in 81 patients (70%), and mean baseline visual acuity was 0.2 ± 0.89 logMAR (Snellen equivalent, 20/32). At baseline, 38 patients (33%) presented with isolated ocular involvement, 54 (45%) with associated central nervous system involvement, and 11 (10%) with other systemic lymphomatous involvement; an additional 12 patients (10%) presented with central nervous system and other systemic involvement. On OCT, tumor infiltration was identified in various retinal layers, including lesions in the subretinal pigment epithelium compartment (91% of eyes), the subretinal compartment (43% of eyes), and the intraretinal compartment (7% of eyes). OCT analysis of eyes with VRL identified 3 main regions of retinal infiltration. Subretinal pigment epithelium location, with or without subretinal infiltration, was the most common pattern of involvement and isolated intraretinal infiltration was the least.
