Objective:

The purpose of this research was to characterize the anterior chamber of 1140 topography exams with Pentacam HR, classifying the angle, depth and volume.

Method:

Retrospective descriptive observational study. Inclusion criteria: male, female and exams with replicable and proper quality specifications.

Results:

Anterior chamber depth median (2.98 mm in females and 3.07 mm in males); anterior chamber angle median (37.4° in females and 39.7° in males); anterior chamber volume median (160 mm3 in females and 171 mm3 in males). All three variables with statistically significant differences by gender.

Conclusion:

The population studied shows low frequency of narrow anterior chamber (13.8%), angle-closure (16.7%) and reduced volume of anterior chamber (15.9%); but specifically, patients over 44 and women have less depth, a more acute angle and lower volume of anterior chamber.
