Pattern Evoked Potential Latency and Contrast Sensitivity in Glaucoma and Ocular Hypertension

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