| Abstract |
|
To evaluate the quantitative relation between the changes of visual field and optic disc in glaucoma, thirty-six patients(58 eyes) with primary glaucoma(P.O.A.G: 29 cases, P.A.C.G.; 7 cases) were enrolled in this study. Visual field defects including the central(25 degrees) and peripheral fields were examined with three different illuminations(2-9, 2-4 and clear filters) by using an automated perimeter(Autofield D, Cavitron, CA, USA) and horizontal and vertical cup/disc(C/D) ratios were traced and 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 Autofield 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 exponential correlation was noted between the summation of the central or the peripheral visual field defect and either horizontal or vertical C/D ratio. |
