GROS-OTERO, J.; ARRUABARRENA-SANCHEZ, C.  and  TEUS, M.. Central corneal thickness in a healthy Spanish population. Arch Soc Esp Oftalmol [online]. 2011, vol.86, n.3, pp.73-76. ISSN 0365-6691.

Objective: To study the central corneal thickness of a Spanish population group and determine the influence of age, gender, axial length and refractive error on central corneal thickness (CCT) values. Methods: An observational, cross-sectional, double masked study was conducted on 357 eyes of consecutive Caucasian patients without ophthalmic disease. They were distributed according to age, and high refractive defects were excluded. Ultrasonic pachymetry and a complete eye examination were performed on all patients. The relationship between the central corneal thickness values and variables of age, refractive error, axial length and gender was assessed. Results: The mean central corneal thickness was 548.21µm with a standard deviation (SD) of 30.7µm (range 464 to 633µm). The normal central corneal thickness value of the population studied was 486.81 to 609.61µm (95% confidence interval). No statistical association was found between central corneal thickness values and variables of age, refractive error, axial length and gender. Conclusions: Central corneal thickness varies according to race. We have analysed, for the first time, normal central corneal thickness values of a healthy Spanish population.
