proliferative sickle cell retinopathy

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.

Proliferative sickle cell retinopathy (PSCR) is characterized by several distinct retinal features. Sea-fan neovascularization represents abnormal new blood vessel growth in the peripheral retina. Peripheral ischemia, caused by occluded blood vessels, leads to areas of retinal non-perfusion. Black-sunburst lesions are hyperpigmented areas resulting from previous hemorrhages and pigment migration. These findings are crucial for diagnosing and managing PSCR, often requiring interventions like laser photocoagulation to prevent further complications.

Sickle cell retinopathy is characterized by several distinct features: sea fan neovascularization, black sunburst lesions, and capillary occlusion. Sea fan neovascularization appears as peripheral neovascular tufts, while black sunbursts are areas of retinal pigment migration due to previous hemorrhages. Capillary occlusion leads to ischemic areas. Laser photocoagulation treatment is used to manage neovascularization and prevent further complications.
