Complex retinal vasclar disorders

• Central retinal artery occlusion (CRAO) is a common cause of unilateral sudden, painless loss of vision in the elderly.1
• CRAO in a 29-year-old is rare but occasionally encountered in a young adult with some predisposing disorder.
• Sickle cell anemia is one of the most common genetic disorders worldwide and can lead to myriad retinal findings that encompass sickle cell retinopathy.
• Here we present a 29-year-old black male with sickle cell anemia who presents with unilateral, sudden painless loss of vision.
• Ultra-widefield imaging vividly reveals a unilateral CRAO superimposed upon bilateral sickle cell retinopathy.
