DENVER — Anterior chamber volume and depth are significantly lower in individuals who are Hispanic white as compared with non-Hispanic white, according to a presenter here.

“This should be taken into consideration when treating these patients,” So Yeon Uhm told Healio/OSN at the Association for Research in Vision and Ophthalmology meeting.

Uhm and colleagues conducted a retrospective study of 103 Hispanic white and 97 non-Hispanic white individuals aged 50 years or older who had surgery for senile cataract. Pupil center pachymetry, pachymetry at vertex, thinnest location, corneal volume, anterior chamber volume and anterior chamber depth were compared between the two groups.

A significant difference existed between Hispanic white and non-Hispanic white groups in anterior chamber volume, with measurements of 130 ± 45.6 mm3 and 146.6 ± 38 mm3respectively (P < .001). Anterior chamber depth also differed between the two groups, with measurements of 2.6 ± 0.5 mm and 2.7 ± 0.4 mm (P = .01) among Hispanic white and non-Hispanic white groups, respectively. No statistically significant differences were observed regarding pupil center pachymetry, pachymetry at vertex, thinnest location or corneal volume.

Anatomical differences between Hispanic white individuals and non-Hispanic white individuals should be considered when preparing for intraocular surgeries, the authors wrote.

The researchers are currently collecting more patient data to analyze and correct for measures such as refractive error, Uhm said.
