Systemic non-Hodgkin's lymphoma masquerading as Vogt-Koyanagi-Harada disease in an HIV-positive patient.

A 29-year-old man presented with decreased visual acuity in both eyes secondary to exudative retinal detachment resembling Vogt-Koyanagi-Harada disease. Although fluorescein angiographic pictures supported the clinical findings, there was no choroidal thickening evident with ultrasonography. In 3 days he developed increased disc oedema with peripapillary haemorrhages in both eyes. Further evaluation revealed HIV-positive status and a systemic non-Hodgkin's lymphoma. The patient responded favourably to the treatment for systemic non-Hodgkin's lymphoma confirming our diagnosis of intraocular metastasis. In bilateral exudative detachment, an absence of choroidal thickening on ultrasonography and the presence of peripapillary haemorrhages should prompt a systemic evaluation for causes other than Vogt-Koyanagi-Harada disease, especially in HIV-positive patients.
