Fundus autofluorescence findings in central serous chorioretinopathy using two different confocal scanning laser...

To compare autofluorescence (AF) findings using wide-field (Optomap) and conventional (HRA-AF) confocal scanning laser ophthalmoscopy (cSLO) systems in patients with central serous chorioretinopathy (CSC), and to investigate the correlations between AF findings and functional and anatomical status.

Optical coherence tomography (OCT) and AF images were compared in 73 eyes with serous retinal detachment (SRD) (group A) and 30 eyes without SRD (group B). We evaluated AF findings from the SRD region, atrophic area, and foveola. Correlations between AF findings and outer retinal abnormalities in OCT and visual acuity (VA) were analyzed.

Optomap-AF was more effective than HRA-AF in identifying the margins of a detached area (P = 0.001) in group A, and for monitoring mild outer retinal damage (P = 0.041) in group B. The foveolar AF grades in both instruments were significantly correlated with VA and central foveal thickness (CFT) in both group A (Optomap, VA r s = 0.33, P = 0.012; CFT r s = -0.38, P = 0.002; HRA, VA r s = 0.62, P < 0.001; CFT r s = -0.70, P < 0.001) and group B (Optomap, VA r s = 0.71, P < 0.001, CFT r s = -0.78, P < 0.001; HRA, VA r s = 0.40, P = 0.026, CFT r s = -0.40, P = 0.030).

Optomap-AF was found to be advantageous for monitoring subretinal status in eyes with SRD, and more accurately reflected mild outer retinal changes in eyes without SRD. Foveolar AF grades of both imaging modalities were significantly correlated with functional and anatomical status.
