OBJECTIVE The purpose of this study was to evaluate three-dimensional optical coherence tomographic findings at the leakage point on fluorescein angiography in central serous chorioretinopathy (CSC) with OCT-ophthalmoscope. METHODS Twenty-seven eyes of 26 patients (23 men, three women; mean age, 50 years; range, 30-72) diagnosed with CSC were examined with OCT-ophthalmoscope, and transverse and longitudinal images were compared with fundus and fluorescein angiography findings. RESULTS Transverse images (C-scan) clearly showed serous retinal detachment in all eyes and irregular lesions in retinal pigment epithelium (RPE) in 26 of 27 eyes (96%). These results agreed with the location of lesions in areas of fluorescein dye leakage on fluorescein angiography. Longitudinal images (B-scan) of irregular RPE lesions in transverse images showed RPE detachment (PED) in 17 eyes (63%), small protrusion of the RPE layer in five eyes (19%), and rough RPE layer in four eyes (15%). CONCLUSIONS OCT-ophthalmoscope detects morphologic changes easily and noninvasively at the point of dye leakage in eyes with CSC.
