The aim of this study was to identify a reduction of light sensitivity as an early sign in glaucoma diagnosis. We have selected 54 glaucoma-suspects, with a normal visual field, but with an asymmetry in mean deviation (MD) value between the two eyes more than 1,5 dB. They underwent standard threshold perimetry (Humphrey 30-2), high-pass resolution perimetry (HRP) and optic nerve head computerized analysis (retinal nerve fiber layer height program). The patients were classified as glaucomatous when the results of two of these tests were significantly abnormal. Our results showed that 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.
