Ocular findings in beta-thalassemia.
Eye examination was performed in a series of 53 patients whose mean age was 19.5 years (range from 11 to 25 years), affected from Cooley's disease, in treatment with transfusions and desferrioxamine in subcutaneous infusion. The most frequent ocular change was fundus mottling appearance like "leopard skin" (15%). We found also lens opacity (11%), drusen (7%), retinal venous tortuosity (5%), without impairment of visual acuity. The pathogenic factors of the ocular change are related to abnormality of iron metabolism. These results suggest that the involvement of desferrioxamine to remove iron from the eyeball is relatively small.
