In sickle cell retinopathy, peripheral ischemia occurs due to the occlusion of small retinal blood vessels by sickle-shaped red blood cells, which have decreased flexibility and increased adhesion to vascular endothelium. These blockages cause oxygen deprivation in the peripheral retina, leading to tissue hypoxia, neovascularization (e.g., sea fan formations), and potential complications like vitreous hemorrhage and retinal detachment if left untreated.

In proliferative sickle cell retinopathy, fluorescein angiography (FA) is crucial for identifying areas of peripheral ischemia and neovascularization, particularly the characteristic “sea fan” neovascular formations. FA highlights areas of non-perfusion and leakage, helping to map the extent of ischemia and guide interventions such as laser photocoagulation to prevent complications like vitreous hemorrhage or retinal detachment.

Sickle cell retinopathy is a manifestation of sickle cell disease, an inherited hemoglobinopathy. It presents with various ocular symptoms resulting from chronic hypoxia and ischemia. These conditions trigger the overexpression of vascular growth factors, leading to retinal neovascularization, pre-retinal or vitreous hemorrhage, and tractional retinal detachment.
