Abstract

Purpose of reviewThe aim of this article is to review the current literature concerning immune reconstitution inflammatory syndrome in relation to the eye. The definition, epidemiology, pathophysiology, risk factors, clinical features, diagnosis and treatment are discussed.Recent findingsImmune reconstitution inflammatory syndrome affecting the eye has been documented in association with cytomegalovirus retinitis following the introduction of highly active antiretroviral therapy in a large number of patients. This syndrome is referred to as immune recovery uveitis, which is presumed to be mediated by recovery of immune responses specific to residual cytomegalovirus antigen located in the eye. In addition to improved immunity itself, risk factors include a low CD4+ T count at the time of initiation of highly active antiretroviral therapy and involvement of a larger proportion of retina. Immune recovery uveitis is a major cause of visual loss and morbidity among patients with AIDS who are receiving highly active antiretroviral therapy.SummaryImmune recovery uveitis is the most common form of immune reconstitution inflammatory syndrome in HIV-infected patients with cytomegalovirus retinitis who are receiving highly active antiretroviral therapy. Clear clinical definitions are required for ocular immune reconstitution inflammatory syndromes to avoid misclassification of other inflammatory conditions. A multidisciplinary approach is important in the diagnosis and management of immune recovery uveitis.
