RESUMO
Atopic dermatitis is usually associated with various ocular complications. We report a 21-year-old Chinese male who presented to our ophthalmology clinic with bilateral retinal detachment and cataracts. The patient had a clear medical history of atopic dermatitis, which had been diagnosed eight years earlier and had been treated with loratadine and pimecrolimus. Cataract surgery was performed for both eyes, combined with scleral buckling for the right eye and pars plana vitrectomy for the left eye. During postoperative follow-up, fundus fluorescein angiography showed retinal vasculitis in both eyes and macular edema in the left eye, which coincided with an exacerbation of atopic dermatitis. Macular edema improved after four months of regular dupilumab treatment in the dermatology department. The ocular condition remained stable three years postoperatively.

An 8-year-old girl presented with a subretinal abscess after strabismus surgery. This was treated successfully with medial rectus suture removal, pars plana vitrectomy, intravitreal antibiotics, and intravenous antibiotics. Recovery was complicated by acute post-infectious retinal vasculitis after tapering high-dose corticosteroids, requiring an extended corticosteroid regimen over 2 months until resolution.

PURPOSE: To discuss diagnosis and management in the case of a patient presenting with bilateral ischemic retinal vasculopathy associated with a previously undiagnosed IgA nephropathy. CASE REPORT: In 2021, a 35-year-old male presented with a sudden onset asymmetric bilateral (OU) visual loss. Best-corrected visual acuity (BCVA) was 20/200 OD, and no light perception (NLP) OS with an associated relative afferent pupillary defect (RAPD). Slit-lamp examination (SLE) confirmed normal anterior segment anatomy OU. Indirect ophthalmoscopy and subsequent fluorescein angiography (FA) confirmed the presence of bilateral arterial attenuation, telangiectatic lesions, associated perivascular sheathing, and capillary leakage. Spectral domain optical coherence tomography (OCT) showed multiple areas of thinning of the inner retina. This constellation of diagnostic findings was highly suggestive of a bilateral ischemic retinal vasculopathy with an inflammatory vasculitis. Based on a high index of suspicion for a systemic etiology, nephrology was consulted, and a diagnosis of IgA nephropathy was confirmed by renal biopsy. Systemic immunomodulatory therapy was initiated. CONCLUSION: Although it is among the most commonly occurring forms of glomerulonephritis leading to renal failure, IgA nephropathy rarely presents with a bilateral retinal vasculopathy. Schölein - Henoch purpura, the other primary disease associated with glomerular IgA deposition, may be indistinguishable from primary IgA nephropathy. A comprehensive retinal examination with multimodal functional and structural ophthalmic diagnostic testing in conjunction with renal biopsy was needed to confirm the diagnosis. It is critical to include primary renal pathology when formulating a differential diagnosis for cases of bilateral retinal vasculitis, particularly in young otherwise healthy patients.

PURPOSE: To report a severe bilateral frosted branch angiitis associated with acute onset of systemic dermatomyositis. METHOD: History and clinical examination, laboratory evaluation, fundus' and skin's color pictures, fluorescein angiography (FA), optical coherence tomography (OCT). RESULTS: A 32-year-old female was referred for a bilateral frosted branch angiitis and vitreitis, with skin rash, muscle pain, weakness, severe headache, compatible with dermatomyositis. After an initial improvement following an aggressive treatment by systemic steroids and mycophenolate mofetil, she was switched to intravenous infliximab (RemicadeTM, Janssen Biotech, Inc. USA) due to lack of efficacy. Nine months later, her visual acuity was improved up to 20/20 in OU, with both retinal vasculitis and vitreitis being solved. CONCLUSION: Dermatomyositis is a severe multiorgan disease which might severely involve eye structures. Anti-TNF-Alpha agents, particularly Infliximab, might offer a rapid control and long-term remission.

OBJECTIVE: Post-hoc analysis to compare the outcomes of brolucizumab 6 mg vs. aflibercept 2 mg in neovascular age-related macular degeneration (nAMD) patients with early persistent retinal fluid in HAWK and HARRIER. METHODS: After 3 monthly loading doses, brolucizumab-treated eyes (N = 730) received injections every 12 weeks (q12w) or q8w if disease activity was detected. Aflibercept-treated eyes (N = 729) received fixed q8w dosing. Early persistent fluid was defined as the presence of subretinal fluid and/or intraretinal fluid up to Week 12. RESULTS: A lower proportion of brolucizumab patients had early persistent retinal fluid compared with aflibercept (11.2% (n = 82) vs. 19.2% (n = 140)). In these patients, 34.1% of the brolucizumab-treated group achieved a ≥ 15 ETDRS letter gain in best corrected visual acuity (BCVA) from baseline at Week 96 compared with 20.7% of the aflibercept-treated group. Brolucizumab achieved numerically better BCVA outcomes (Week 96: brolucizumab, +6.4 letters; aflibercept, +3.7 letters) and significantly greater central subfield thickness reductions versus aflibercept from baseline through Week 96 (Week 96: -202 µm vs. -145 µm; p = 0.0206). Brolucizumab demonstrated an overall favourable benefit/risk profile in this patient cohort. In their unmasked, post-hoc review, the Safety Review Committee identified two cases of retinal vasculitis and no cases of retinal vascular occlusion in the brolucizumab arm; no cases of retinal vasculitis or retinal vascular occlusion were identified in the aflibercept arm. CONCLUSION: In this analysis, anatomical and visual outcomes were better with brolucizumab compared with aflibercept. Brolucizumab may therefore achieve greater disease control than aflibercept in nAMD patients with early persistent retinal fluid.

A 23-year-old man presented with the blurring of vision in the left eye for 4 days. Best-corrected visual acuity was 6/6 N6 in both eyes. Examination revealed an unremarkable right eye while the left eye showed occlusive retinal vasculitis with no retinitis, choroiditis, or macular involvement. Fundus fluorescein angiography confirmed the same. History revealed the patient had received 2nd dose of Covishield vaccination 4 weeks before the onset of symptoms. Blood investigations were negative for infectious or any systemic autoimmune disease. Serum homocysteine and serum CMV IgG levels were grossly increased while tests for antiphospholipid syndrome were weakly positive. He responded well to a combination of intravitreal and oral antivirals, oral steroids for vasculitis and tablets Clopilet and Homin. This case is extremely intriguing in terms of the involvement of the adenoviral vector vaccine either as a causative factor or being just a coincidental finding.

INTRODUCTION: Ocular involvement in Behçet disease occurs is most patients and can be the presenting organ. Intra-ocular inflammation (uveitis) related to Behçet disease is mainly a panuveitis including an occlusive retinal vasculitis. Recurrent inflammation can result in the development of ocular complications, including macular edema and retinal neovascularization, with up to a quarter of eyes developing vision loss. Diagnosis is based on clinical ophthalmic findings and ocular imaging including retinal fluorescein angiography and optical coherence tomography. Early diagnosis and treatment may prevent the development of ocular complications and vision loss. Treatment is based primarily on systemic corticosteroids and 2nd-line immunosuppressive agents, particularly anti-tumor necrosis factor α agents. Extensive treatment, prevention of relapses and complications can result in long term stable vision.

AIM: To present an outline of acquired atypical forms of ocular toxoplasmosis (OT) in childhood, with reference to the 100th anniversary of the discovery of this etiology by Professor Janků from Czechoslovakia, who was first to describe the clinical congenital picture of OT characterised by macular scar. MATERIAL AND METHODS: Symptoms of intraocular bilateral neuritis appeared in a 6-year-old girl, with visual acuity (VA) bilaterally 0.1. Toxoplasmic etiology was demonstrated in laboratory tests, and the patient was immunocompetent. Following treatment with macrolide antibiotic and parabulbar application of corticosteroid, the condition was normalised stably at VA 1.0 in both eyes. Bilateral retinal vasculitis was determined in an 8-year-old boy, with VA of 0.25 in the right eye and 0.25 in the left, with a medical history of strabismus detected after suffering from varicella. The examination for toxoplasmosis was negative, but pronounced general hypogammaglobulinaemia classes IgG, IgM and IgA was detected. Immunosuppressive and immunomodulatory therapy did not produce the desired effect, and the condition progressed to retinochoroiditis. Due to blindness and dolorous glaucoma, enucleation of the right eye was performed at the age of 15 years. Histologically toxoplasmic cysts with bradyzoites were detected, a subsequent laboratory test demonstrated toxoplasmic etiology upon a background of persistent regressing hypogammaglobulinaemia. General anti-toxoplasma and subsequent immunosuppressive treatment did not produce the desired effect, and at the age of 22 years the patient lost his sight also in the left eye. CONCLUSION: Atypical form of OT intraocular neuritis in an immunocompetent patient had a favourable course, whereas retinal vasculitis with retinochoroiditis in a temporarily immunocompromised patient ended in bilateral blindness.

PURPOSE: To assess the 52-week efficacy and safety of brolucizumab 6 mg administered every 4 weeks compared with aflibercept 2 mg dosed every 4 weeks in eyes with neovascular age-related macular degeneration (nAMD) and persistent retinal fluid. DESIGN: Multicenter, randomized, double-masked phase 3a study. PARTICIPANTS: Participants with recalcitrant nAMD (persistent residual retinal fluid despite previous frequent anti-vascular endothelial growth factor treatment). METHODS: Eyes were randomized (2:1) to intravitreal brolucizumab 6 mg or aflibercept 2 mg every 4 weeks up to and including week 100. MAIN OUTCOME MEASURES: The primary end point was analysis of noninferiority in mean best-corrected visual acuity (BCVA) change from baseline to week 52 (margin, 4 letters). Other key end points included change in central subfield thickness (CST) from baseline to week 52, fluid-free status (no intraretinal fluid and no subretinal fluid), and safety. RESULTS: At week 52, brolucizumab was noninferior to aflibercept in BCVA change from baseline (least squares mean difference, -0.6 Early Treatment Diabetic Retinopathy Study letters; 95% confidence interval [CI], -2.1 to 0.9; P < 0.001). A total of 4.8% and 1.7% of participants reported a 15-letter or more BCVA loss from baseline at week 52 in the brolucizumab and aflibercept groups, respectively. In eyes treated with brolucizumab compared with those treated with aflibercept, the CST was reduced significantly (P < 0.001), and a significantly greater proportion of eyes were fluid free at week 52 (40.4% brolucizumab vs. 19.0% aflibercept; 95% CI, 13.9-29.0; P < 0.001). Incidence of intraocular inflammation (IOI), including retinal vasculitis and retinal vascular occlusion, were 9.3% (0.8% and 2.0%) for brolucizumab versus 4.5% (0% and 0%) for aflibercept, respectively. CONCLUSIONS: Visual acuity outcomes in previously treated participants with nAMD and persistent retinal fluid receiving brolucizumab 6 mg dosed every 4 weeks were noninferior to aflibercept 2 mg dosed every 4 weeks, with superior anatomic outcomes. However, incidences of IOI, including retinal vasculitis and retinal vascular occlusion, also were higher, leading to study termination.

BACKGROUND: Patients with psoriatic arthritis (PsA) may develop uveitis, a potentially serious ocular complication. PsA-related uveitis may result in significant morbidity and even vision loss if underdiagnosed or under-treated. We presented a case with long-standing recurrent uveitis and retinal vasculitis successfully managed by fortified systemic immunomodulators for systemic PsA. CASE PRESENTATION: A 47-year-old woman was referred under the impression of acute anterior uveitis in her right eye in recent one month. Ocular examinations showed panuveitis in both eyes with intense vitreous opacity in her right eye. Fundus fluorescence angiography revealed retinal vasculitis in both eyes. Systemic surveys excluded the possibility of infection but showed an elevated inflammation marker. With intensive immunosuppressive treatment, inflammation resolved and the vision improved. CONCLUSION: Our case highlights not only the importance of intensified systemic therapy in treating PsA-related uveitis but the importance of multidisciplinary collaboration. Recurrent uveitis may be an indicator of disease activity prior to other inflammatory markers.

IMPORTANCE: Limited data exist on the real-world safety outcomes of patients with neovascular age-related macular degeneration treated with brolucizumab (Beovu). OBJECTIVE: To determine the real-world incidence of intraocular inflammation (IOI), including retinal vasculitis (RV) and/or retinal vascular occlusion (RO), for patients with neovascular age-related macular degeneration who underwent brolucizumab treatment. Additionally, potential risk factors associated with these adverse events were evaluated. DESIGN, SETTING, AND PARTICIPANTS: This cohort study included patients with neovascular age-related macular degeneration in the Intelligent Research in Sight (IRIS) Registry and Komodo Healthcare Map. Patients initiating and receiving 1 or more brolucizumab injections from October 8, 2019, to June 5, 2020, with up to 6 months of follow-up were included. INTERVENTION: Brolucizumab injections. MAIN OUTCOME AND MEASURES: Incidence of IOI (including RV) and/or RO and RV and/or RO and risk stratification for the identified risk factors. RESULTS: Of 10â¯654 and 11â¯161 included eyes (from the IRIS Registry and Komodo Health database, respectively), the median follow-up times were 97 and 95 days. Most eyes switched from another anti-vascular endothelial growth factor agent (9686 of 10â¯654 [90.9%] and 10â¯487 of 11â¯161 [94.0%], respectively), most commonly aflibercept (7160 of 9686 [73.9%] and 7156 of 10â¯487 [68.2%]), and most were from women (6105 of 10â¯654 [57.3%] and 6452 of 11â¯161 [57.8%]). The overall incidence of IOI and/or RO was 2.4% (255 of 10â¯654 eyes) and 2.4% (268 of 11â¯161 eyes) for the IRIS and Komodo groups, respectively, and RV and/or RO, 0.6% (59 of 10â¯654 eyes and 63 of 11â¯161 eyes), respectively. Patients with a history of IOI and/or RO in the 12 months before brolucizumab initiation had an increased observed risk rate (8.7% [95% CI, 6.0%-11.4%] and 10.6% [95% CI, 7.5%-13.7%]) for an IOI and/or RO event in the 6 months following the first brolucizumab treatment compared with patients without prior IOI and/or RO (2.0% in both data sets). There was an increased estimated incidence rate in women (2.9% [95% CI, 2.5%-3.3%] and 3.0% [95% CI, 2.6%-3.4%]) compared with men (1.3% [95% CI, 1.0%-1.7%] and 1.4% [95% CI, 1.0%-1.7%]), but this risk was not as large as that of a prior IOI and/or RO. Similar findings were observed for patients with RV and/or RO events. CONCLUSIONS AND RELEVANCE: The incidence rate of IOI and/or RO was approximately 2.4%. Patient eyes with IOI and/or RO in the 12 months prior to first brolucizumab injection had the highest observed risk rate for IOI and/or RO in the early months after the first brolucizumab treatment. However, given study limitations, the identified risk factors cannot be used as predictors of IOI and/or RO events, and causality with brolucizumab cannot be assessed.

PURPOSE: To present a case of idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome that was successfully managed with serial intravitreal aflibercept injections. METHODS: Ophthalmic imaging and visual acuity were used to monitor disease state and track treatment methods to determine the most valuable combination of treatment medication and treatment interval. RESULTS: A 28-year-old woman with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome status after panretinal photocoagulation of both eyes presented with bilateral cystoid macular edema. We demonstrate successful management of retinal cystoid macular edema associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome using serial intravitreal aflibercept injections. CONCLUSION: Intravitreal aflibercept has a useful role in managing the potential retinal complications associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome and provides further insights into treatment of the later stages of this rare disease.

PURPOSE: To compare the time to resolution of perivascular infiltrates in tubercular retinal vasculitis (TRV) between anti-tubercular therapy (ATT) alone, and in combination with systemic corticosteroids. METHODS: Observational retrospective cohort study in a tertiary eye centre in eastern India. Patients with TRV who were treated with anti-tubercular therapy (ATT) alone (Group A), or in combination with systemic corticosteroids (Group B) were included in the study. Eyes with additional inflammatory signs (cystoid macular oedema, vitritis ≥2+, optic disc oedema) were excluded. Resolution was defined as complete disappearance of perivascular infiltrates on seven-field fundus photographs. Descriptive statistics were used for demographic data. A linear mixed effects model was applied to adjust for intereye correlations, in patients with bilateral disease. The primary outcome measure was time to resolution of perivascular infiltrates. Secondary outcome measure was need for laser or surgical intervention for management of complications of TRV. RESULTS: Fifty eyes of 39 patients (Group A 21/18 and Group B 29/21) were included. Both groups had similar demographics and severity of vasculitis. All patients had complete resolution of TRV. On adjusting for intereye correlation, the mean difference in time to resolution between the two groups (Group A, 3.24 [95% CI 2.69-3.77] months, and Group B, 4.76 [95% CI 3.52-5.99] months) was not statistically significant (0.96 weeks [-0.52 to 2.45] p = 0.21). Vaso-occlusive complications and healing patterns were similar in both groups. CONCLUSIONS: ATT alone, may be sufficient for resolution of perivascular infiltrates, in TRV without additional inflammatory signs.

PURPOSE: To report our experience with a peculiar case of asynchronous bilateral retinal vascular occlusion in a patient suffering from membranoproliferative glomerulonephritis. CASE REPORT: A 57-year-old dialysed male affected by membranoproliferative glomerulonephritis who underwent kidney transplantation complained of a sudden vision loss in his right eye (RE). His best-corrected visual acuity (BCVA) was 20/40 in RE and 20/20 in the left eye (LE); ophthalmological and fluorangiographic examinations revealed unilateral retinal obliterative vasculitis with panuveitis and apparent sparing of contralateral eye. About 6 months later the patient developed a branch retinal vein occlusion associated with a papillary neovascular membrane in LE. Corticosteroid therapy was administered and immunosuppressant dosage was increased with macular oedema reduction in both events. CONCLUSION: We report a case of unilateral retinal obliterative vasculitis and subsequent contralateral retinal neovascularization and branch retinal vein occlusion in a patient affected by membranoproliferative glomerulonephritis.

PURPOSE: To report a patient with submacular hemorrhage due to retinal angiomatous proliferation (RAP) in tubercular retinal vasculitis (TRV). METHODS: Case report. RESULTS: We report a 33-year-old Asian Indian patient of TRV presenting with capillary non-perfusion areas, submacular hemorrhage and venous loops. The patient presented with sudden onset decrease in vision in the right eye. Multimodal imaging revealed presence of retinal vascular anastomosis and stage 2 RAP. Systemic examination was within normal limits. Laboratory evaluation revealed positive Mantoux and interferon gamma release assay. He underwent right eye intravitreal injection of recombinant tissue plasminogen activator (12.5µg/0.1ml) with 100% sulphur hexafluoride (SF6) tamponade. The patient had successful displacement of the submacular hemorrhage with some improvement in visual acuity. CONCLUSION: This case highlights that rare vascular alterations such as RAP can develop in subjects with ocular tuberculosis.

PURPOSE: To present a case of refractory systemic lupus erythematosus (SLE)-associated retinal vasculitis that responded to the anti-tumor necrosis factor (TNF)-alpha inhibitor adalimumab as corticosteroid-sparing therapy. METHODS: Descriptive case report of a patient with SLE with retinal vasculitis complicated by an ischemic retinal vein occlusion and cystoid macular edema. RESULTS: A 30-year-old female patient with a history of SLE presented with retinal vasculitis and an ischemic, branch retinal vein occlusion with macular edema in the left eye. Oral corticosteroid was administered along with mycophenolate mofetil (MMF) as a corticosteroid-sparing agent. Despite MMF therapy, the patient developed an exacerbation of her vasculitis with the involvement of both eyes. Adalimumab was initiated with a resultant resolution of retinal vasculitis as a corticosteroid-sparing strategy with over 2 years of follow-up. CONCLUSION: Anti-TNF-alpha therapy with adalimumab may be effective as a corticosteroid-sparing agent in select patients with ocular inflammation associated with SLE.

Frosted angiitis is a rare form of retinal vasculitis in which venous development gives it an appearance of perivascular frost. It is most often of idiopathic origin but can also be found in the context of infectious (most often viral) or inflammatory pathologies (lupus erythematosus, sarcoidosis or granulomatosis with polyangiitis). As with most vasculitis, frosty angiitis can be complicated by occlusion of the central retinal vein. Close monitoring is necessary as well as rapid treatment based on high-dose systemic corticosteroid therapy as well as intraocular injections of anti-VEGF compounds if necessary.
L'angéite givrée est une forme rare de vascularite rétinienne dont l'engainement veineux lui confère un aspect de givre périvasculaire. Elle est le plus souvent d'origine idiopathique, mais peut également se rencontrer dans le cadre de pathologies infectieuses (virales, le plus souvent ) ou inflammatoires (lupus érythémateux, sarcoïdose ou encore granulomatose avec polyangéite). Comme pour la plupart des vascularites, l'angéite givrée peut se compliquer d'une occlusion de la veine centrale de la rétine. Un suivi rapproché est nécessaire ainsi qu'un traitement rapide basé sur une corticothérapie systémique à haute dose ainsi que des injections intraoculaires d'anti-VEGF si nécessaire.

Chronic low-grade retinal inflammation is an essential contributor to the pathogenesis of diabetic retinopathy (DR). It is characterized by increased retinal cell expression and secretion of a variety of inflammatory cytokines; among these, IL-1ß has the reputation of being a major driver of cytokine-induced inflammation. IL-1ß and other cytokines drive inflammatory changes that cause damage to retinal cells, leading to the hallmark vascular lesions of DR; these include increased leukocyte adherence, vascular permeability, and capillary cell death. Nuclear factor of activated T-cells (NFAT) is a transcriptional regulator of inflammatory cytokines and adhesion molecules and is expressed in retinal cells. Consequently, it may influence multiple pathogenic steps early in DR. We investigated the NFAT-dependency of IL-1ß-induced inflammation in human Müller cells (hMC) and human retinal microvascular endothelial cells (hRMEC). Our results show that an NFAT inhibitor, Inhibitor of NFAT-Calcineurin Association-6 (INCA-6), decreased IL-1ß-induced expression of IL-1ß and TNFα in hMC, while having no effect on VEGF, CCL2, or CCL5 expression. We also demonstrate that INCA-6 attenuated IL-1ß-induced increases of IL-1ß, TNFα, IL-6, CCL2, and CCL5 (inflammatory cytokines and chemokines), and ICAM-1 and E-selectin (leukocyte adhesion molecules) expression in hRMEC. INCA-6 similarly inhibited IL-1ß-induced increases in leukocyte adhesion in both hRMEC monolayers in vitro and an acute model of retinal inflammation in vivo. Finally, INCA-6 rescued IL-1ß-induced permeability in both hRMEC monolayers in vitro and an acute model of retinal inflammation in vivo. Taken together, these data demonstrate the potential of NFAT inhibition to mitigate retinal inflammation secondary to diabetes.

The wet form of age-related macular degeneration is characterized by neovascular pathologies that, if untreated, can result in edemas followed by rapid vision loss. Inhibition of vascular endothelial growth factor (VEGF) has been used to successfully treat neovascular pathologies of the eye. Nonetheless, some patients require frequent intravitreal injections of anti-VEGF drugs, increasing the burden and risk of complications from the procedure to affected individuals. Recombinant adeno-associated virus (rAAV)-mediated expression of anti-VEGF proteins is an attractive alternative to reduce risk and burden to patients. However, controversy remains as to the safety of prolonged VEGF inhibition in the eye. Here, we show that two out of four rAAV serotypes tested by intravitreal delivery to express the anti-VEGF drug conbercept lead to a dose-dependent vascular sheathing pathology that is characterized by immune cell infiltrates, reminiscent of vasculitis in humans. We show that this pathology is accompanied by increased expression in vascular cell adhesion molecule 1 (VCAM1) and intercellular adhesion molecule 1 (ICAM1), both of which promote extravasation of immune cells from the vasculature. While formation of the vascular sheathing pathology is prevented in immunodeficient Rag-1 mice that lack B and T cells, increased expression of VACM1 and ICAM1 still occurs, indicating that inhibition of VEGF function leads to expression changes in cell adhesion molecules that promote extravasation of immune cells. Importantly, a 10-fold lower dose of one of the vectors that cause a vascular sheathing pathology is still able to reduce edemas resulting from choroidal neovascularization without causing any vascular sheathing pathology and only a minimal increase in VCAM1 expression. The data suggest that treatments of neovascular eye pathologies with rAAV-mediated expression of anti VEGF drugs can be developed safely. However, viral load needs to be adjusted to the tropisms of the serotype and the expression pattern of the promoter.

BACKGROUND: This report describes the clinical course of choroidal neovascular membrane (CNV) in West Nile virus-associated chorioretinitis. CASE PRESENTATION: A 28-year-old Italian woman was referred to our institution because of reduced visual acuity in the left eye dating back 4 months. A diagnosis of retinal vasculitis in the right eye and chorioretinitis with CNV in the left eye was made. A complete workup for uveitis revealed positivity only for anti-West Nile virus immunoglobulin M (IgM), while immunoglobulin G (IgG) was negative. Whole-body computed tomography and nuclear magnetic resonance imaging of the brain were also negative. Therefore, the patient was treated with a combination of oral prednisone (starting dose 1 mg/kg per day) and three intravitreal injections of bevacizumab 1.25 mg/0.05 ml, 1 month apart. Fourteen days from starting corticosteroid therapy and after the first intravitreal injection, the patient experienced increased visual acuity to 0.4. Response to therapy was monitored by clinical examination, ocular coherence tomography (OCT), OCT angiography and retinal fluorescein angiography. Three months later, resolution of CNV in the left eye was achieved and no signs of retinal vasculitis were detected in the right eye, while serum IgM for West Nile virus turned negative and IgG positive. CONCLUSION: CNV may be a complication of West Nile virus-associated chorioretinitis, and only subclinical retinal vasculitis may also be found even in non-endemic regions.
