PURPOSE: To describe fundus autofluorescence (FAF) characteristics of adult-onset foveomacular vitelliform dystrophy (AOFVD) and to perform a comparative evaluation of FAF patterns and functional response. METHODS: Fifteen patients with AOFVD and 10 healthy volunteers underwent complete ophthalmic examination, including visual acuity determination (Early Treatment Diabetic Retinopathy Study charts), blue-light autofluorescence (BL-AF) analysis, near-infrared autofluorescence (NIR-AF) analysis, and microperimetry. RESULTS: Three different patterns of BL-AF (normal, focal, and patchy) and two of NIR-AF (focal and patchy) were identified in AOFVD. Abnormal BL-AF and NIR-AF patterns were detectable in 86% and 100% of cases, respectively. Patchy BL-AF and NIR-AF patterns are associated with the worst functional outcomes. CONCLUSIONS: AOFVD can be associated with different FAF patterns. A functional correlate with visual acuity and retinal sensitivity, measured by means of microperimetry, can be found.
