Comparison of saccadic reaction time between normal and glaucoma using an eye movement perimeter
Indian Journal of Ophthalmology , Volume 62 - Issue 1 p. 55- 59
Aim: To compare the saccadic reaction time (SRT) in both the central and peripheral visual field in normal and glaucomatous eyes using eye movement perimetery (EMP). Materials and Methods: Fifty-four normal and 25 glaucoma subjects underwent EMP and visual field testing on the Humphrey Field Analyser (HFA) 24-2 program. The EMP is based on infrared tracking of the corneal reflex. Fifty-four test locations corresponding to the locations on the 24-2 HFA program were tested. SRTs at different eccentricities and for different severities of glaucoma were compared between normal and glaucoma subjects. Results: Mean SRT was calculated for both normal and glaucoma subjects. Mann-Whitney U test showed statistically significant (P < 0.001) differences in SRT's between normal and glaucoma subjects in all zones. Conclusion: SRT was prolonged in eyes with glaucoma across different eccentricities.
