Abstract PURPOSE: To find possible correlations between the morphologic macular changes revealed by fundus autofluorescence (FAF) and the functional parameters such as visual acuity and retinal sensitivity in patients with chronic central serous chorioretinopathy (CSC). DESIGN: Prospective, cross-sectional study. METHODS: Forty-six eyes (39 consecutive patients) with chronic CSC were studied with FAF and microperimetry (MP). Retinal sensitivity value maps were exactly superimposed over FAF images. The following microperimetric parameters were applied: central 10-degree visual field, 4-2-1 strategy, 61 stimulation spots, white monochromatic background, stimulation time 200 ms, stimulation spot size Goldmann III. A possible relationship between MP and FAF was investigated. RESULTS: Mean best-corrected visual acuity (BCVA) was 20/32 (median 20/25, range 20/20-20/200). BCVA was significantly correlated with FAF findings (Mann-Whitney test; P < .0001). A positive concordance between FAF and MP evaluation was also found (total concordance of 0.720 with a kappa of Cohen of 0.456). The hypo-autofluorescent areas showed decreased retinal sensitivity, while adjacent areas of increased FAF could be associated to both normal and decreased retinal sensitivity. Absolute scotoma, defined as 0 dB retinal sensitivity, corresponded with absence of autofluorescence. CONCLUSIONS: Altered FAF in chronic CSC patients has a functional correlation quantified by microperimetry. This study confirms the impact of FAF changes on retinal sensitivity and their value to reflect the functional impairment in chronic CSC.
