Abstract
The latency of the first major positive component (P1) of the pattern reversal visually evoked potential (VEP) and constrast sensitivity, using the Arden grating plates, were measured in 3 groups of age matched subjects. One group consisted of 14 normal subjects (mean age 66 yrs.) with no ocular disease; a second group contained 21 patients (mean age 58 yrs.) with ocular hypertension; and a thrid group contained 20 patients (mean age 66 yrs.) with glaucoma. Analysis of the Arden grating scores revealed no significant differences between the 3 groups. These findings indicate that the Arden gratings have limited usefulness in the detection of glaucoma, at least in older patient populations. On the other hand, the VEP data showed that the mean P1 latency for the glaucomatous eyes was significantly longer than the P1 latency for the normals and ocular hypertensives. Further, there was no significant difference in mean P1 latency between the normals and ocular hypertensives.
