title: Central corneal thickness in a Puerto Rican population.
abstract: OBJECTIVE
  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.
  
  
  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<0.002) and Hispanic populations (P<0.03), but thicker than the published values for African Americans (P<0.05). Among ethnic subgroups in Puerto Rico, no significant differences in the mean CCT were observed.
  
  
  CONCLUSIONS
  In this Puerto Rican population, the mean observed CCT was thicker than that published for African Americans, but thinner than those for white and other Hispanic populations within the United States.
