A total of 153 patients with human immunodeficiency virus (HIV) infection underwent complete ophthalmologic examinations for the presence of any eye pathology. We wanted to show a correlation between such pathology and total CD4+ lymphocyte count, believed to be an indicator of immunologic status. The most frequently encountered lesions were cotton-wool patches, vascular congestion, hemorrhages, chorioretinitis, segmental vasculitis, and pallid papilla. Almost all of the patients with ocular anomalies also had a CD4+ count of less than 200 cells/mm3 suggesting that ocular lesions have a negative prognostic significance even in asymptomatic patients who present with a severe impairment of their immune system
