Sickle cell retinopathy
In sickle cell disease, widefield fluorescein angiography (FA) is superior for evaluating peripheral ischemia. This imaging modality captures extensive retinal areas, enabling the detection of non-perfusion zones, neovascularization, and other ischemic changes often missed in standard FA. Widefield FA is critical for guiding management strategies, including laser photocoagulation. #SickleCellDisease #WidefieldFA #PeripheralIschemia…
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…
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 retinopathy: Nonperfusion
In diabetic retinopathy, panretinal photocoagulation (PRP) is a standard treatment for managing peripheral ischemia. Fluorescein angiography (FA) and wide-field OCT Angiography (OCTA) are essential for identifying areas of ischemia. These imaging techniques provide detailed maps of retinal perfusion, guiding effective PRP treatment to prevent further disease progression. #DiabeticRetinopathy #PRP #PeripheralIschemia #FA #OCTA…
