    Author: Imamura Y, Fujiwara T, Spaide RF.
    Journal: Ophthalmology; 2011 Apr; 118(4):700-5. PubMed ID: 21055816.
    Abstract:
    PURPOSE: To investigate the fundus autofluorescence (FAF) abnormalities in central serous chorioretinopathy (CSC) and evaluate potential correlations with visual acuity. DESIGN: Retrospective, observational case series. PARTICIPANTS: Four hundred seventy-five eyes of 238 patients with CSC. METHODS: Consecutive patients with CSC underwent FAF imaging, as well as routine ophthalmologic examinations. Confluent hypoautofluorescence was defined as a region of absent autofluorescence greater than one fourth of a disk diameter. Granular hypoautofluorescence was defined if there was a grainy or coarse region of decreased fluorescence as compared with normal surrounding areas greater than one fourth of a disc diameter in size. A descending tract was a downward leading swathe of decreased autofluorescence originating from the posterior pole to extend below the inferior arcade. MAIN OUTCOME MEASURES: The pattern and frequency of FAF abnormalities and their correlations with corrected visual acuity. RESULTS: The mean age of the subjects was 57.1 years (standard deviation, 13.3), and 181 (76.1%) were male. Confluent and granular hypoautofluorescence was detected in the macula of 54 (11.4%) and 300 (63.2%) of 475 eyes, respectively. Descending tracts from the macula were observed in 43 (9.1%) eyes and from the optic disc in 43 (9.1%) eyes. Multiple regression analysis revealed that confluent hypoautofluorescence of the macula, granular hypoautofluorescence of the macula, and increasing age all were independent predictors of decreased visual acuity. CONCLUSIONS: The FAF abnormalities in CSC show multiple distinct patterns and seem to provide functional information.
