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.

Oral fluorescein angiography and fluoroscopy: determination of plasma fluorescein levels and clinical application.

One hundred oral fluorescein angiographic explorations were performed in 85 patients of both sexes, mean age 55.57 years, and range 8 to 77 years. Fluorescein was administered as one 250-mg (15 patients) or 500-mg (70 patients) capsule per 15 kg of body weight. In 15 fasting and 15 postprandial patients administered 500-mg capsules, no significant differences by group were found between fluorescein plasma levels. Fundus fluorescence under slitlamp illumination was poor for patients receiving the lower dosage of fluorescein, whereas at the higher dosage it was visible in all but one patient. The best filters were found to be a Kodak-Wratten 47A for the excitation filter and Kodak-Wratten 8 for the barrier filter. With a conventional fundus camera and fluorescein angiography filters, good photographs were achieved in all cases. The integrity of the blood-retina barriers was explored for various chorioretinal pathologies.
