Central corneal thickness in a Puerto Rican population.

Purpose: To evaluate mean central corneal thickness (CCT) in a Puerto Rican population and to compare our findings with published mean central corneal thicknesses of white, Hispanic, and African American populations in the United States.

Patients And Methods: Volunteers at the Centro Médico, San Juan, Puerto Rico, completed a survey and participated in an eye examination, which included measurement of intraocular pressure and central corneal thickness.

Results: Of 588 Puerto Rican participants, the mean CCT was 541+/-33 microm, which is significantly thinner than the published values for white populations (P<0.
