A 51-year-old man with acquired immunodeficiency syndrome and cytomegalovirus retinitis had bilateral endogenous fungal endophthalmitis. Cultures yielded Fusarium species. Histopathologic examination showed a severe necrotizing acute and granulomatous reaction, with numerous fungal elements in the retina and uveal tract. Fungal elements were seen in the lens, sclera, and emissarial vessels. Angiopathic infiltration by fungus and widespread thrombosis produced retinal and choroidal infarction. In some areas, fungal infection coexisted with cytomegalovirus retinitis. The bilateral distribution suggests hematogenous seeding of the eyes. The eye findings were the first clinically apparent manifestations of fungal disease in this patient.
