Abstract

To Know the quantitative relation between the visual field defects and the disc cupping in glaucoma, 14 patients(26 eyes) with primary open angle glaucoma were studied. Visual field defects was measured with semi-automated Autofield-D perimeter. Optic disc was photograped with Canon CF-60Z wide angle camera and neuroretinal rim area was analyzed by using microcomputer (VAX-11/750) digitizer system. The following results were obtained: 1. Neuroretinal rim area on the nasal side was larger than that on the temporal side(p<0.05). There were no significance between superior and inferior side. 2. In the case of visual field defects, nasal side was larger than temporal side.(p<0.05). There was no significance between superior and inferior side. 3. The correlation between neuroretinal rim area and visual field area was significant in the mild visual field defects detected by using 2.9 filter and the moderate and marked field defects detected with either 2.4 or clear filter. 4. The correlation between neuroretinal rim area and visual field area(r=0.696) was higher than that between cup-disc ratio and visual field defects(r=0.568).
