Diagnosis and treatment of ocular large cell lymphoma may lessen visual loss and prolong life. Although reports in the literature have described retinal infiltrates in eyes with large cell lymphoma, they have focused on the more prominent vitreous and subretinal pigment epithelial findings. Eyes with retinal infiltrates and hemorrhagic retinal necrosis are usually believed to harbor a microbial infection. The authors describe 5 patients, aged 57 to 85 years, with ocular lymphoma in whom the most prominent initial findings were in the retina.Patients presented with findings suggestive of an infectious retinal necrosis. When the initial therapy failed, investigators performed a vitreous biopsy. Two patients had a concomitant retinal biopsy. Radiation therapy was given to four patients.All five patients had vitreous cells. Three patients had prominent perivascular exudate. Four patients had grayish-white retinal infiltrates, and three patients had associated retinal hemorrhage. Three patients had subretinal small white spots. An edematous thickened retina developed in three patients, and hemorrhagic retinal necrosis developed in three patients. The initial diagnosis was believed to be acute retinal necrosis (ARN) in three patients, toxoplasmosis in one patient, and frosted branch angiitis in one patient. Vitreous biopsy was positive in two patients but negative in three patients. In two of these three patients, the diagnosis was established by retinal biopsy.Ocular lymphoma should be considered in the differential diagnosis of retinal vasculitis or necrotizing retinitis in a middle-aged or older patient. Retinal biopsy may be helpful in establishing the diagnosis.
