Asymptomatic BRVO
A superior nasal branch retinal vein occlusion (BRVO) is usually asymptomatic, as the macula is typically spared. These cases are often identified incidentally during routine examination. Fluorescein angiography (FA) reveals localized capillary nonperfusion in the affected quadrant, indicating retinal ischemia. Despite the absence of symptoms, close follow-up is essential to monitor for neovascular complications. #BRVO #FluoresceinAngiography…
Secondary macular telangiectasia (BRVO)
Secondary macular telangiectasia due to branch retinal vein occlusion (BRVO) is characterized by vascular changes in the macula. Fluorescein angiography (FA) reveals dilated and tortuous macular capillaries, areas of leakage, and capillary telangiectasia. FA helps assess the extent of macular involvement, guiding management decisions such as anti-VEGF therapy to address macular edema. #SecondaryMacTel #BRVO…

BRVO and asteroid hyalosis
Branch Retinal Vein Occlusion (BRVO) and asteroid hyalosis can coexist, posing challenges in retinal imaging. Asteroid hyalosis, characterized by calcium-lipid deposits in the vitreous, can obscure fundus details. #BRVO #AsteroidHyalosis #RetinaImaging #OCT #FA #RetinalVeinOcclusion #retina #oftalmo #ophthalmology #oftalmologia #oftalmología #ophtalmologie #офтальмологія #офтальмология #οφθαλμολογία #retinography2024 #CIRRUS6000 #CLARUS700…
BRVO: Macula sparing
Branch retinal vein occlusion (BRVO) sparing the macula often remains asymptomatic, as central vision is preserved. These cases are typically identified incidentally during routine fundus examination or imaging. Management usually involves observation unless complications like peripheral ischemia or neovascularization develop, requiring interventions such as laser photocoagulation. #BRVO #AsymptomaticBRVO #PeripheralIschemia #RetinaImaging #retina…
Branch Retinal Vein Occlusion
In branch retinal vein occlusion (BRVO), fluorescein angiography (FA) is used to detect areas of retinal non-perfusion, indicating ischemia. Laser photocoagulation is often employed to treat these ischemic areas, preventing neovascularization and further complications. This targeted treatment reduces the risk of vision loss and stabilizes retinal function. #BRVO #FluoresceinAngiography #NonPerfusion #LaserPhotocoagulation #RetinaImaging…
Old BRVO
Old Branch Retinal Vein Occlusion (BRVO) can lead to degenerative cystoid areas visible on OCT. En-face minimum intensity projection imaging helps to identify these cystoid spaces. OCTA reveals areas of non-perfusion and abnormalities in the foveal avascular zone (FAZ), providing detailed insights into the vascular changes and retinal health post-BRVO. #BRVO #OCT #EnFaceImaging #OCTA #NonPerfusion #FAZ #RetinaImaging #retina #oftalmo #ophthalmology…
