Abstract

Purpose

To compare corneal tomographic parameters between Hispanic White and non-Hispanic White patients using Pentacam data.

Methods

This retrospective study evaluated preoperative Pentacam data from 641 patients 50 years or older who underwent surgery for senile cataract and self-identified as Hispanic or non-Hispanic White. Patients of non-White race or multiethnic groups, or a history of surgery, trauma, or any abnormality of the cornea or anterior segment were excluded. Cornea and anterior segment parameters, as measured with Pentacam, were then compared between Hispanics and non-Hispanics.

Results

There were 352 Hispanic White and 289 non-Hispanic White patients. These included 231 men and 410 women, with a mean age of 69.5 ± 8.2 years. There were no significant differences between Hispanics and non-Hispanics in front or back keratometry or amount of front astigmatism. However, Hispanics had a greater amount of back astigmatism (0.36 ± 0.19 vs 0.32 ± 0.17 diopter, P = 0.04). Moreover, there was a statistically significant difference in front steep axis of the left eyes between Hispanics and non-Hispanics (97.8 ± 47.9 vs 108.2 ± 48.9 deg, P = 0.01), and a marginally significant difference in front steep axis of the right eyes (81.0 ± 48.2 vs 73.5 ± 49.9 deg, P = 0.06). Hispanics also had a lower vertex pachymetry (548.1 ± 34.5 vs 553.4 ± 37.4 μm, P = 0.04) and a smaller anterior chamber volume (134.7 ± 39.0 vs 146.1 ± 39.9 mm3, P < 0.001).

Conclusions

There are some differences in cornea and anterior segment parameters between Hispanics and non-Hispanics 50 years or older who underwent surgery for senile cataract. However, such differences may not be clinically significant.
