[Computer-assisted calculation of the neuroretinal rim area. Early diagnosis and surveillance of primary open-angle glaucoma].

The neuroretinal rim area computation is the choice complementary overhaul in early diagnosis and watching of primitive open angle glaucoma. The interest of this overhaul are objectivity, swiftness and plainess of production. The author devised a system who measure precisely, safely and swiftly this area. For a best watching of your patients with glaucoma or suspected of having glaucoma, it's possible, with this process, to know the neuroretinal rim area of your patients. It's necessary to take a color slide of the optic nerve head (Kodachrome 64 asa, angle 45 degrees) and measure parameters on the patient (length in mm of the flashed slit on the optic nerve head with the slotted light and Goldmann lens, the measurement in dioptries of the ametropia and the radius in mm of the anterior surface of the cornea).
