Abstract：
PURPOSE:To investigate the autofluorescence (AF) characteristics of punctate inner choroidopathy (PIC) and to evaluate the progression rate of retinal pigment epithelium (RPE) atrophy lesions in PIC using confocal scanning laser ophthalmoscopy. METHODS:Twenty-two eyes of 14 PIC cases and 21 eyes of 21 non-proliferative diabetic retinopathy (NPDR) cases which received retinal coagulation as a control group were enrolled in this study. Enhanced depth imaging optical coherence tomography (EDI-OCT) and AF were recorded from all patients at 18 months follow-up. The RPE atrophy areas of PIC and laser scars in NPDR were analyzed using the Region Finder software of the Heidelberg Eye Explorer. This software allows direct export of AF images from the database and semi-automated detection of atrophic areas by shadow correction, vessel detection, and selection of seed points. RESULTS:At baseline, both hyperfluorescence and hypofluorescence were observed in the lesions of PIC eyes with a focal elevation of RPE and corresponding disruption of the ellipsoid region of the inner segment ellipsoid zone (EZ). In contrast, hypo-AF was detected when there was a lack of RPE. The mean progression rate of RPE atrophy in PIC and NPDR were 3.735 mm(2)/year (0.056-0.545) and 0.127 mm(2)/year (0.015-0.466), respectively. Compared with the atrophy area in the last visit, the progression rate in PIC was significantly greater than that in NPDR (Z=5.615, P<0.0001). CONCLUSIONS:The results of AF reflect the status of PIC and the progression rate of RPE atrophy in PIC, which can be used to predict the progress of PIC noninvasively.
