Abstract
We used a digital image processor to make multiple measurements from the fluorescein angiograms of 53 cases of central serous chorioretinopathy (CSC) associated with single leaks. We determined the area of the base of each serous detachment, the location of its geometric center (CM), the area of the RPE leak, the distance from the fovea to the leak, and the distance from the leak to the CM. The distribution of leaks across the base of the detachments was nonrandom (P < 0.005) with leaks clustering near the centers of the detachments. When the leak was found within 1 disc diameter from the fovea, the center of the detachment was located virtually at the foveola, suggesting that the central macula is predisposed to the development of CSC. Detachments associated with “smokestack” leaks were significantly larger than those associated with round pinpoint leaks (P < 0.02).
