Contact Lens & Anterior Eye. 28(2):53-6, 2005 Jun.
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+/-1.0mm with the Colvard pupillometer and 4.8+/-0.9mm with the Nidek auto-refractor in low mesopic light conditions. The mean photopic pupil diameter was 3.3+/-0.8mm with the Colvard pupillometer and 3.9+/-0.8mm with the Nidek auto-refractor.
CONCLUSION:
The pupil sizes are very similar with both instruments.
