Abstract
Purpose: To compare pupil sizes measured with the Colvard pupillometer, Procyon pupillometer, and NIDEK OPD-Scan.
Methods: Pupil diameter was measured in 90 consecutive eyes from 55 patients under mesopic and scotopic light conditions with all three instruments.
Results: The mean scotopic pupil diameter was 6.3+/-0.98 mm with the Colvard pupillometer and 6.45+/-1.01 mm with the Procyon pupillometer. The mean mesopic pupillometer was 5.58+/-1.01 mm with the Procyon pupillometer and 6.26-0.99 mm with the
Conclusions: The mesopic pupil diameter measured with the NIDEK OPD-Scan is more consistent with the scotopic pupil diameter measured with the Procyon and Colvard pupillometers than the mesopic pupil diameter measured with the Procyon pupillometer.
