Abstract
|
|
|
To evaluate the quantitative relation between the changes of visual field and optic disc in glaucoma, thirty-five patients(56 eyes) with primary glaucoma (P.O.A.G: 29 case, P.A.C.G: 7 case) were enrolled in this study.
Visual field defects including the central(25 degrees) and peripheral fields were examined with three different illumination(2~9, 2~4 and clear filters) by using an automated perimenter (Autofield D, Cavitron, CA, USA) and horizontal and vertical
cup/disc(C/D) ratios were traced calculated with the disc photographs taken with a fundus camera(CF-60Z, Canon Inc, Tokyo, Japan).
Each defect by using 2.9, 2.4 and clear filter of autof8ield D in either the central or the peripheral visual field has the relationship of arc tangent with either the horizontal or the vertical C/D ratio. The exponetial correlation was noted
between
the summation of the central or the peripheral visual field defect and either horizontal or vertical C/D ration.
