Sickle cell retinopathy
In sickle cell retinopathy, black sunburst lesions are areas of retinal pigment epithelial (RPE) hyperplasia and migration resulting from prior retinal hemorrhages. These lesions appear as dark, pigmented spots with spiculated edges, resembling a sunburst pattern. They are typically located in the mid-periphery of the retina and indicate chronic retinal ischemia and damage. #SickleCellRetinopathy #BlackSunburstLesions #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…
SCR: Oral dye fluorescein angiography
Oral dye fluorescein angiography is a valuable technique for evaluating sickle cell retinopathy in children. This method involves administering fluorescein dye orally, which is safer and better tolerated by pediatric patients than intravenous injection. The angiography helps visualize retinal blood flow, identify ischemic areas, and detect neovascularization, guiding effective treatment strategies. #SickleCellRetinopathy…
