To define the anterior chamber depth (ACD) measurements in a Hispanic population.
A retrospective study evaluating 124 Hispanic patients scheduled for refractive surgery at the Cornea and Refractive service from July 2012 to November 2013. For each patient, the following information was obtained for both eyes using Orbscan: ACD, white-to-white corneal diameter, central corneal thickness and pupil diameter. Descriptive statistics and correlations were performed for all the variables.
A total of 124 subjects, 58 males and 66 females, were evaluated, with a mean age of 35 (±15.1) years. The mean ACD was 2.92 (±0.44) mm for general population; 2.99 (±0.4) mm in males and 2.88 (±0.46) mm in females. The mean white-to-white corneal diameter was of 11.7 (±0.38) mm, central corneal thickness 534.35 (±36.2) µm and a pupil diameter of 4.2 (±1.01) mm, all for males and females. A weak positive significant correlation was found between ACD and pupil diameter, r= 0.393 (p<0.001).
The mean anterior chamber depth in Hispanic population of 2.92 mm differs slightly from the mean ACD of 3.05 mm found in the Caucasian population, 3.00 found in Chinese and 2.96 found in Eskimos. The difference observed between males and females is of importance when evaluating patients, as females have a shallower anterior chamber. The ACD is important when evaluating glaucoma and cataract patients. The importance of this study lies in the lack of literature describing this information in Hispanic population.
