Abstract

Purpose: To compare prospectively, pupil size with the Nidek AR700A auto-refractor and the Colvard pupillometer. Methods: Pupil diameter was measured in 46 eyes at 2 min intervals in a low mesopic and under photopic light conditions. Results: The mean pupil diameter was 4.8 ± 1.0 mm with the Colvard pupillometer and 4.8 ± 0.9 mm with the Nidek auto-refractor in low mesopic light conditions. The mean photopic pupil diameter was 3.3 ± 0.8 mm with the Colvard pupillometer and 3.9 ± 0.8 mm with the Nidek auto-refractor. Conclusion: The pupil sizes are very similar with both instruments.
