To determine if there is a correlation between anterior chamber (AC) depth and central corneal thickness (CCT), average AC angle and average peripheral corneal thickness (PCT), AC angle and PCT at approximately 180 degrees and 0 degrees using the Pentacam (Oculus, Inc., Wetzlar, Germany).
A retrospective review of 80 Pentacam evaluations from 40 patients with topographically normal corneas was performed. Measurements recorded include AC depth, CCT, average AC angle, average PCT, angle and PCT at approximately 180 and 0 degrees. Exclusion criteria were previous ocular surgery, glaucoma, trauma, external eye disease, and contact lens use. The relationships among parameters were analyzed using Pearson's correlation and linear regression analysis.
There was no significant correlation between AC depth and CCT (r=0.03), average AC angle and average PCT (r =-0.04), and AC angle and PCT at approximately 180 (r=-0.03) and 0 degrees (r=-0.05). Also, there was no significant difference in the average nasal versus temporal angle.
Corneal thickness is not related to anterior chamber depth or angle and is an independent factor.
