Abstract

Purpose: To acquire a normal central choroidal thickness (CT) database of a local Hispanic healthy population by enhanced depth imaging optic coherence tomography.

Methods: A cross-sectional study performed on 350 Eyes of 175 healthy volunteers who underwent high-definition scanning using SD-OCT (RTVue) with enhanced depth imaging technique (EDI). The sample was matched by gender and age to the local 2012 population distribution. The healthy status was confirmed by a comprehensive ophthalmic examination. Patients with axial length shorter than 21mm or larger than 25mm were excluded. The nasal-temporally oriented line was used to measure the choroid thickness. A total of 5 measurements were taken of each eye.

Results: A total of 190 eyes from 95 women were evaluated (55.23%) and 154 eyes from 77 men (44.76%). The average choroidal thickness for women were: Group 1: 20-29 years: 352,99μ; Group 2: 30-39 years: 348,93μ; Group 3: 40-49 years: 331,53μ, Group 4: 50-59 years: 302,31μ, Group 5: 60-69 years: 292,97μ, and Group 6: 70 years or older: 265,52μ. The average choroidal thickness for men were: Group 1: 20-29 years: 359,7μ; Group 2: 30-39 years: 347,4μ; Group 3: 40-49 years: 284,7μ, Group 4: 50-59 years: 291,8μ, Group 5: 60-69 years: 276,1μ, and Group 6: 70 years or older: 182μ.

Conclusions: To our knowledge this is the first cross-sectional population-based study done in Hispanic patients. We found differences that were statistically significant in CT among different gender and age groups.
