Review of external ocular disease associated with aids and HIV infection.

External ocular disease associated with human immunodeficiency virus (HIV) infection can often be overlooked by the eye care practitioner. Different types of external ocular disease can be an indication of the patient's overall immune status as well as the stage of HIV infection. The external ocular sequelae of HIV infection can be of visual consequence for the patient. Eye care practitioners need to become familiar with these conditions. The diagnosis and management of the following ocular conditions associated with HIV infection are reviewed: conjunctival microvascular disease, dry eye, allergic conjunctivitis, microsporidial keratoconjunctivitis, herpes zoster ophthalmicus, herpes simplex keratitis, molluscum contagiosum, fungal keratitis, bacterial keratoconjunctivitis, and Kaposi's sarcoma (KS).
