To compare clinical profile and visual outcomes of occlusive versus non-occlusive retinal vasculitis (RV). A retrospective comparative study 284 patients were enrolled, including 124 patients with occlusive RV (ORV) and 160 patients with non-occlusive RV (NORV). Patients with ORV were older (p ≤ 10–3), predominantly male (p ≤10-3), with less bilateral involvement (31.5% vs 53,4%; p ≤ 10−3). Infectious RV was more frequently diagnosed in the ORV group than in the NORV group (48.8% vs 32.9%, p =.006). Behçet disease and ocular tuberculosis were the leading causes of ORV. Idiopathic RV, Behçet disease, and sarcoidosis were the most common causes of NORV. Independent predictive factors of poor visual outcome were worse baseline visual acuity in both groups (p =.006 and p ≤ 10–3, respectively), and retinal hemorrhages (p =.048) and optic atrophy (p =.040) in the ORV group. Occlusive and non-occlusive RV have distinctive clinical and etiological profile. [ABSTRACT FROM AUTHOR]

To report a case of unilateral acute foveolitis following COVID-19 vaccination. A case report. A 24-year-old woman developed a sudden blurring of vision in the left eye (LE) 5 days after receiving the first dose of COVID-19 vaccine. Examination of the LE showed a visual acuity at 20/40, 2+ cells in the vitreous, and a small yellow-orange foveal subretinal lesion. Late-phase fluorescein angiography showed a mild diffuse retinal vascular leakage and a faint foveal hyperfluorescence. ICG angiography showed in the late-phase hypofluorescence of the centrofoveal lesion. OCT B-scan demonstrated a conical hyperreflective subfoveal lesion on the retinal pigment epithelium associated with disruption of the outer retinal layers. En-face OCT revealed granular hyperreflective specks mainly in the inner nuclear layer. Work-up results were unremarkable. The patient received oral prednisolone with subsequent full functional and anatomic recovery. Foveolitis may rarely occur as a complication of COVID-19 vaccination. [ABSTRACT FROM AUTHOR]

Objective: To report acute multifocal retinitis in association with serologically-proven Coxiella (C) Burnetii infection (Q fever) with endocarditis. Material and methods: A single case report documented with multimodal imaging. Results: A 67-year-old cattle breeder presented with a 2-week history of persistent fever, headache, and floaters in both eyes. On examination, his best-corrected visual acuity was 20/20, and there was 1+ vitreous cells in both eyes. Bilateral fundus examination showed multiple small superficial white retinal lesions scattered in the posterior pole and midperiphery associated with a few retinal hemorrhages. These retinal lesions did not stain on fluorescein angiography (FA) and showed focal hyperreflectivity and thickening primarily involving the inner retinal layers on optical coherence tomography (OCT). There also was a band-like hyper-reflective area in the middle retina consistent with paramacular acute middle maculopathy. Transthoracic echocardiogram (TTE) showed a mobile echodensity on the anterior aortic leaflet consistent with a diagnosis of endocarditis. Elisa assays performed on paired serum samples collected 2 weeks apart showed increase in antibodies against C burnetii from 60 IU/ml to 255 IU/ml. The patient was treated with doxycycline 100 mg twice a day for 18 months, with subsequent resolution of the endocarditis. Sequential ocular examinations showed gradual resolution of all acute retinal findings without visible scars. Conclusion: Acute Q fever, caused by C burnetii infection, should be considered in the differential diagnosis of acute multifocal retinitis. A systematic cardiac assessment with echocardiography is essential for early diagnosis of associated endocarditis and for prompt administration of appropriate antibiotic treatment to improve clinical outcomes.

Purpose: To provide an overview of the role of multimodality approach to the diagnosis and assessment of uveitic macular edema (UME). Methods: Review of literature. Results: Optical coherence tomography (OCT) has become the gold standard in the detection, quantification, monitoring of treatment, and determination of prognosis in UME. Fluorescein angiography provides essential information on blood-retinal barrier disruption as a result of intraocular inflammation and allows detection of associated retinal ischemia and neovascularization. Dye-less OCT angiography can reveal the presence of various qualitative and quantitative retinal microvascular changes mostly involving the deep capillary plexus. Reading acuity and retinal sensitivity assessed by microperimetry represent sensitive measures for visual dysfunction in UME and may supplement distance visual acuity in the follow-up of patients with UME. Conclusion: Conventional and new imaging modalities and ancillary tests complement each other in the diagnosis, assessment, and monitoring of patients with UME. [ABSTRACT FROM AUTHOR]

Purpose: To report optical coherence tomography angiography (OCT-A) findings in eyes with ocular sarcoidosis (OS) and to compare these findings with those of fluorescein angiography (FA). Methods: Observational, cross-sectional, case-control study. Patients presenting with OS involving the posterior segment were evaluated using FA, structural-OCT and OCT-A. OCT-angiograms of the superficial (SCP) and deep (DCP) capillary plexuses and choriocapillaris (CC) were qualitatively and quantitatively analyzed. Results: OCT-A seemed more sensitive than FA in detecting perifoveal capillary arcade disruptions, areas of hypoperfusion/non-perfusion and capillary abnormalities (p<0.05). Capillary hypoperfusion was more frequently detected in the DCP than in SCP, conversely capillary abnormalities were more often observed at the level of the SCP. Capillary vessel density values were significantly lower in eyes with OS than in healthy controls both at the level of DCP and CC (p<0.05). Conclusion: The depth-resolved nature of OCT-A allowed new insights on OS-induced microvascular and perfusion impairments. [ABSTRACT FROM AUTHOR]

Purpose: To describe clinical features and multimodal imaging findings in primary vitreoretinal lymphoma (PVRL). Methods: Medical records and imaging findings of 4 patients (4 eyes) diagnosed with PVRL were retrospectively reviewed. Detailed ophthalmic examination, fundus photography, fundus autofluorescence (FAF), fluorescein angiography (FA), optical coherence tomography (OCT) and OCT angiography (OCTA) were analysed in all patients. All patients underwent vitreous biopsy for diagnosis confirmation. Brain magnetic resonance imaging (MRI) was performed in all cases. Results: There were 2 women and 2 male patients with a mean age of 68.75 years. Visual blurring was the presenting symptom in all patients (100%). Clinical findings at presentation included vitritis in 4 eyes (100%), vitreous clumps in 2 eyes (50%), subretinal deposits in 3 eyes (75%) and exudative retinal detachment in one eye (25%). FAF showed granular hyperautofluorescence and hypoautofluorescence lesions in 3 eyes (75%) and blockage by mass lesion was seen in 1 eye. The most common pattern on FA was hypofluorescent lesions with a "leopard spot" appearance (75%). OCT revealed hyperreflective sub retinal lesions between retinal pigment epithelium and Bruch's membrane with an undulating shape (seasick sign) in 3 eyes (75%) and epiretinal membrane in one eye. OCTA showed areas of decreased signal on choriocapillaris slab in 2 eyes (50%). MRI of the globes and brain showed no abnormality in all cases. Vitreous cytology revealed atypical mononuclear cells consisting with the diagnosis of PVRL in all cases. The patients were referred to oncology unit. Conclusions: The diagnosis of PVRL is challenging. Multimodal imaging provides novel insights into features of PVRL. [ABSTRACT FROM AUTHOR]

Purpose: To report 2 cases of branch retinal artery occlusion (BRAO) associated with Behççet disease (BD). Design: Small case series. Methods: Review of two patients'' charts, fluorescein angiography, and optical coherence tomography (OCT). Results: The authors report two young patients, diagnosed with BD, who developed decreased vision secondary to BRAO for the first patient and cilioretinal artery occlusion associated with branch retinal vein occlusion for the second patient. In the two cases, artery occlusion was associated with active intraocular inflammation. Conclusions: BRAO, with subsequent transient or permanent visual impairment, is an additional ocular complication of BD. [ABSTRACT FROM AUTHOR]

Background: White dot syndromes (WDS) are a group of idiopathic multifocal inflammatory conditions that can be recognized and distinguished by lesion morphology, other specific clinical features, imaging findings, and disease course. Our purpose is to describe an atypical case of WDS with choriocapillaris ischemia shown by multimodal imaging including swept-source OCT angiography (OCTA) in a 30-year-old woman with latent tuberculosis.Findings: At presentation, visual acuity in the left eye was 20/500. Clinical findings included macular granularity, diffuse outer retinal discoloration with satellite yellow-white dots, and disc margin blurring. Fluorescein angiography showed early confluent areas of choroidal hypofluorescence and late perifoveal punctate hyperfluorescence. There was choroidal hypofluorescence in a geographic configuration throughout the indocyanine green angiography sequence. OCTA showed confluent geographic areas of loss of signal in the choriocapillaris. Work-up revealed latent tuberculosis. The patient received corticosteroids and prophylactic anti-tubercular treatment. Nine months later, visual acuity had improved to 20/20, and there were some residual retinal pigment epithelium changes.Conclusion: Atypical WDS associated with choriocapillaris hypoperfusion may show features of multiple evanescent white dot syndrome and acute posterior multifocal placoid pigment epitheliopathy melting together.
