Abstract
Retinal occlusion as an advanced complication of sickle cell disease
Highlights
Sickle-cell anaemia is a hereditary condition (SS or seen in HbC (SC) haemoglobin) common in African people
We describe the case of a 31-yearold man with sickle cell anemia who developed this complication
SCD and sickle beta-thalassemia (SThal) are associated with more severe ocular disease; the proliferative sickle cell retinopathy incidence in sickle-cell anemia is less than sickle-cell disease and thalassemia
Summary
Sickle-cell anaemia is a hereditary condition (SS or SC haemoglobin) common in African people. Owing to occlusion of small vessels at the retinal periphery and ischemia, fibro-vascular proliferation occurs. Localized chorio-retinal scars are characteristic of the condition. May be it causes loss of vision from traction retinal detachment or vitreous haemorrhage but it could be prevented with photocoagulation. Para-orbital ptosis it’s showing as a facial infarction. A proliferative retinitis is common in Hb SC disease and may
