Abstract
Purpose :
To investigate qAF changes in central serous chorioretinopathy (CSCR).
Methods :
Fundus AF images (488-nm excitation) were acquired from 22 eyes of 15 patients with CSCR (Mean age: 51.27±10.71; 7 bilateral). qAF8 values were calculated as the mean of 8 concentric segments (qAF8) located at an eccentricity of 7-9 degree. Change in qAF were correlated with anatomical changes observed on horizontal SD-OCT scans.
Results :
In 9/22 eyes, serous detachment was involving the parapapillary area. qAF8 values were higher in eyes involving the parapapillary area compared to CSCR confined to fovea (7.88±4.38 vs. 6.72±2.37; p<0.05). Involvement of parapapillary area also resulted an increase in qAF compared to fellow eyes (436.07±203.1 versus 392.36±249.91; p=0.7). Color-coded qAF images revealed the extension of qAF alterations beyond the clinically visible borders of CSCR.
Conclusions :
qAF reveals two different presentations of CSCR and displays the extend of the RPE pathology beyond visible borders of the clinical picture.
