Abstract

Purpose: : To compare the pupil size with the NeurOptics pupillometer & the Wavescan wavefront system at the scotopic level of illumination (0.05 lux).

Methods: : The pupil diameter was measured in 60 eyes of 30 patients using the following devices: NeurOptics Pupillometer (BD ophthalmic systems) and Wavescan Wavefront system (VISX). 21 females and 9 males were enrolled with an age range of 20 to 65 years.A single observer obtained the pupil measurement with the NeurOptics pupillometer after allowing the patient to be dark-adapted for 1 minute. The same observer recorded pupil size measurements obtained when corneal topographic analysis was performed with the VISX wavescan. 3 measurements were obtained with both the pupillometer and the wavescan on each eye and an average of the 3 measurements were obtained. Statistical evaluation was performed using the paired 2 sample of means T- test.

Results: : The mean pupil diameter in the right eye is 6.87 mm and 6.70 mm respectively with the VISX wavescan & pupillometer respectively. The mean pupil diameter in the left eye is 6.94 mm and 6.77 mm respectively with the VISX wavescan & pupillometer respectively. There was no statistically significant difference in the pupil size with the NeurOptic pupillometer & the VISX wavescan wavefront system. Mean pupil diameter with the wavescan was higher in each of the groups.
