PURPOSE: The objectives of the study were to determine whether different light conditions influence anterior segment parameters of healthy subjects as measured with Pentacam. METHODS: Anterior segment parameters of 50 healthy subjects were measured with Pentacam under dim light condition and room light condition. Paired t test was used to compare measurements under different light conditions.
RESULTS: Mean age in the study group was 31.7±8.5 (range; 22–43) years. Measurements between 2 sessions were signiﬁcantly different for the parameters of anterior chamber depth, anterior chamber volume (ACV), and pupilla diameter (p<0.05).
CONCLUSION: Taking Pentacam Scheimpflug measurements in room light causes a significant increase in anterior chamber angle and decrease in ACV as well as pupilla diameter in healthy subjects. When using Pentacam, the effect of light condition on these parameters should be considered and all measurements should be obtained under standard dim light conditions as suggested by the manufacturer.
