title: [Functional and morphologic changes in the posterior ocular field in primary open-angle glaucoma. I. Relation between the fluorescein angiography image of the papilla and the c/d ratio].
abstract: In 53 eyes with the primary open angle glaucoma optic disc perfusion condition was examined fluoroangiographically in different stages of the pathologic process. Findings were divided into the following groups: 1) physiologic angiogram, 2) relative transient defect in filling, 3) relative permanent defect in filling, 4) absolute defect in filling. According to c/d ratio found the group was divided into: 1) c/d from 0.3 to 0.45; 2) from 0.46 to 0.6; 3) c/d from 0.61 to 0.8; 4) c/d more than 0.8. Statistically significant mutual correlation (Friedman's correlation coeficient p = 0.7325) was found in the above mentioned stages of the pathologic process examined fluorangiographically and by means of the c/d ratio. Thus it was clinically confirmed that in all stages of the glaucomatous atrophy of optic disc proportion ratios between capillaries and the other tissues remained constant. Important role of vessels played in the genesis of glaucomatous atrophy of optic disc was shown.
