Summary
The average central corneal thickness (CCT) in Puerto Ricans is thinner than in US white and Hispanic populations, but thicker than in African Americans. This finding is important for understanding eye health variations.
Area of Science:
- Ophthalmology
- Corneal Research
- Population Health
Background:
- Central corneal thickness (CCT) is a critical ocular biometric.
- Variations in CCT exist across different ethnic and geographic populations.
- Understanding CCT in diverse populations is essential for accurate ophthalmic assessments.
Purpose of the Study:
- To determine the mean central corneal thickness (CCT) in a Puerto Rican cohort.
- To compare Puerto Rican CCT with published data from US white, Hispanic, and African American populations.
Main Methods:
- A survey and eye examination were conducted on 588 volunteers in San Juan, Puerto Rico.
- Intraocular pressure and central corneal thickness were measured.
- Data were analyzed to compare CCT across different ethnic groups.
Main Results:
- The mean CCT for Puerto Rican participants was 541+/-33 micrometers.
- Puerto Rican CCT was significantly thinner than that of US white (P<0.002) and Hispanic (P<0.03) populations.
- Puerto Rican CCT was significantly thicker than that of US African American populations (P<0.05).
Conclusions:
- The mean central corneal thickness in Puerto Ricans differs from that in various US ethnic groups.
- Puerto Rican CCT is thinner compared to white and Hispanic populations but thicker than African Americans in the US.
- No significant CCT differences were found among ethnic subgroups within Puerto Rico.
