[Functional and morphologic changes in the posterior ocular field in relation to primary open-angle glaucoma. II. Relation of perimetry findings and the c/d ratio].

Non-selected group of 53 patients with primary open-angle glaucoma, divided into the 4 groups according to the degree of optic disc atrophy with c/d ratio: I. 0.3-0.45, II. 0.46-0.6, III. 0.61-0.8, and IV. > than 0.81 statistically compared with perimetric results divided also into the 4 groups of relevance: I. negative or relative scotoma, II. spotted or arcuate and also absolute defects without the connection with blind spot, III. arcuate also absolute defects connected with blind spot, IV. larger than upward defects. Mutual relation of these groups evaluated by Friedman's correlative coefficient of nonparametric data (= 0,3317) and graphically by Chi quadrat test. Discussed problem of early changes of visual field and c/d ratio at glaucoma and the use of correlation between the functional changes and structural characteristics of optic disc.
