An image analyzer study of central serous chorioretinopathy.

The angiographic characteristics of central serous chorioretinopathy (CSC) were studied by analyzing digitalized angiograms with an IMAGEnet system. We determined the type of leak, its location, and its distance from the fovea and from the center of the detachment. Round leaks were located farther from the detachment center and farther from the fovea than smokestack leaks. Detachments tended to center on the fovea regardless of the leak to fovea distance. These findings suggest that for serous detachment of the sensory retina to develop and be maintained, there must be a diffuse dysfunctional area of retinal pigment epithelium and a focal leak.
