Purpose : To examine central corneal thickness (CCT) and its associated factors in a general population in Russia

Methods : The Ufa Eye and Medical Study (UEMS) included inhabitants with an age of 40+ years and living in an urban region in the province capital city of Ufa/Bashkortostan and in an rural region in the vicinity of Ufa. The particpants underwent an interview and a detailed ophthalmological examination including refractometry and biometry.

Results : The study included 1087 individuals with a mean age of 61.7 ± 10.4 years (range: 40 to 91 years) and a mean axial length of 23.1 ± 1.29mm (range:19.0-29.3mm). Thicker CCT (mean: 538±38µm; median:538µm;range:344-657µm) was associated (multivariate analysis) with younger age (P<0.001; regression corefficient r= -0.12) and lower keratometric readings (P=0.04;r=-0.07). It was not significantly associated with gender (P=0.94), level of education (P=0.06), axial length (P=0.36), and anterior chamber dpeth (P=0.89). Intraocular pressure readings (Goldmann applanation tonometry) were correlated (P<0.001;r=0.34) with CCT: IOP(mmHg)=0.04xCCT(µm)-6.75.

Conclusions : CCT was slightly thinner in the South Russian UEMS study population than in Western European populations and thicker than in Indians or Afro-Americans. As in other populations, CCT was not associated with axial length, while intraocular pressure readings depends on CCT.
