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…
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…
Sickle cell retinopathy
Sickle cell retinopathy is characterized by peripheral retinal ischemia, which can be effectively visualized using fluorescein angiography (FA). FA reveals areas of non-perfusion and neovascularization, helping to identify the extent of ischemia and guide treatment strategies such as laser photocoagulation to prevent further retinal complications. #SickleCellRetinopathy #FluoresceinAngiography #PeripheralIschemia #RetinaImaging…
Diabetic macular edema
Diabetic retinopathy is characterized by increased vascular permeability, leading to leakage of blood and fluid into the retina. Fluorescein angiography (FA) is used to assess this permeability, revealing areas of leakage, microaneurysms, and also neovascularization. FA helps in evaluating the extent of retinal damage and guiding treatment decisions. #DiabeticRetinopathy #VascularPermeability #FluoresceinAngiography #FA #RetinaImaging #retina…
