The aim of this study was to identify an early sign in glaucoma diagnosis, using automated perimetry and pattern electroretinography. We have selected 54 glaucoma-suspects, underwent threshold perimetry (Humphrey 30-2), high-pass resolution perimetry (HRP) and pattern electroretinography (PERG). The patients were classified as glaucomatous when the results of two of these tests were significantly abnormal. We observed a significant (p<0,01) correlation between an asymmetry in MD value and the results of the other tests. Our results showed 26 (89,65%) of the 29 subjects whose difference in MD value between the two eyes was less than 1,8 dB, had normal responses to the other tests. Among the 25 subjects who showed a difference of more than 1,8 dB, 12 (48%) had a glaucoma diagnosis confirmed by other tests.

Abstract
The aim of this study was to identify an early sign in glaucoma diagnosis, using automated perimetry and pattern electroretinography. We have selected 54 glaucoma-suspects, underwent threshold perimetry (Humphrey 30-2), high-pass resolution perimetry (HRP) and pattern electroretinography (PERG). The patients were classified as glaucomatous when the results of two of these tests were significantly abnormal. We observed a significant (p<0,01) correlation between an asymmetry in MD value and the results of the other tests. Our results showed 26 (89,65%) of the 29 subjects whose difference in MD value between the two eyes was less than 1,8 dB, had normal responses to the other tests. Among the 25 subjects who showed a difference of more than 1,8 dB, 12 (48%) had a glaucoma diagnosis confirmed by other tests.
