[Progress in the studies on cytomegalovirus retinitis]

Abstract

Cytomegalovirus retinitis (CMVR) is the commonest opportunistic ocular infection in patients with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS), typically occurs when CD4+ T cell counts fall below 50/mm3. CMVR accounts for the majority of the vision loss associated with HIV-related eye diseases. However progress in the studies on CMVR, including the prevalence, clinical features, differential diagnosis and recent advances in the management of CMVR is reviewed.
