A detailed clinical evaluation included hypochromic conjunctiva, peripheral vascular occlusion with non-perfusion areas led us to suspect sickle cell disease retinopathy. The images of fluorescein angiography showed peripheral arteriovenous anastomosis with non-perfusion areas; the optical coherence tomography revealed a thinner neuroepithelium with a thicker choroid; also, hemoglobin electrophoresis and peripheral blood smear documenting sickle cell trait.
