Purpose.
To determine how different grades of cataract affect sensitivity threshold and saccadic reaction time (SRT) in eye movement perimetry (EMP).
Methods.
In EMP, the visual field is tested by assessing the saccades that a subject makes towards peripheral stimuli using an eye tracker.
Forty-eight cataract patients underwent pre- and postoperative EMP examination in both eyes.
The subjects had to fix a central stimulus presented on the eye tracker monitor and to look at any detected peripheral stimulus upon its appearance.
A multilevel mixed model was used to determine the factors that affected the sensitivity threshold and the SRT as a function of cataract grade.
Results.
We found no effect of cataract severity (LOCS III grades I through IV) on SRT and the sensitivity thresholds.
In cataract of LOCS III grade V, however, we found an increase by 27% and 21% ( p < 0.001 ), respectively, compared to the SRT and the sensitivity threshold in LOCS III grade I.
Eyes that underwent cataract surgery showed no change in mean SRTs and sensitivity thresholds after surgery in LOCS III grade IV and lower.
Conclusion.
The present study shows that EMP can be readily used in patients with cataract with LOCS III grade IV and below.
