Prevalence of Intermediate-Stage Age-Related Macular Degeneration in Patients With Acquired Immunodeficiency Syndrome

AGE-RELATED MACULAR DEGENERATION (AMD) IS the leading cause of late-onset visual impairment and blindness in persons over 65 years of age.1,2 Age-related macular degeneration is staged as early, intermediate, or late. Small drusen are the hallmark of earlystage AMD; intermediate-stage AMD consists of extensive medium-size drusen or any large drusen, with or without pigment changes. Late-stage AMD is defined by either choroidal neovascularization or geographic atrophy.3–6 In the United States, it is estimated that ~1.2 million persons have neovascular AMD; 970,000 have geographic atrophy; and 8 million have intermediate-stage AMD.1

Antiretroviral-treated, immune-restored, human immunodeficiency virus (HIV)-infected persons have a marked reduction in opportunistic infections and a substantially increased lifespan compared to those from the era before modern combination antiretroviral therapy.7–10 However, despite the improved immune function and increased lifespan, antiretroviral therapy does not fully restore health. Compared to similarly-aged, non-HIV-infected peers, antiretroviral-treated, immune-restored, HIV-infected persons have a substantially shortened lifespan, largely owing to an increased risk of non–acquired immunodeficiency syndrome (AIDS) diseases associated with aging.11–14 These diseases include cardiovascular disease, non-AIDS cancers, metabolic diseases, and neurocognitive decline, and collectively suggest that antiretroviral-treated, immune-restored HIV infection is associated with an “accelerated/accentuated aging” phenotype.11 Therefore, we undertook to evaluate whether persons with AIDS had an increased prevalence of AMD, using retinal photographs taken at enrollment in the Longitudinal Study of the Ocular Complications of AIDS (LSOCA) cohort.
