To examine the prevalence of myopia in a general population in Russia.
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.
The study included 721 individuals with a mean age of 60.8 ± 9.9 years (range: 40 to 91 years) who had not undergone cataract surgery. Mean refractive error was +0.40 ± 1.90 diopters (median: 0.75 diopters; range: -11.0 to +5.50 diopters). Myopia defined as refractive error of <-0.50 diopters, <-1.00 diopters, and <-6 diopters was present in 1116 (16.1%), 99 (13.7%) and 8 (1.1%) of the study population. Longer axial length (mean: 23.1±1.27 mm;median:23.0mm;range:19.0-29.3 mm) was associated (multivariate analysis) with younger age (P=0.03; regression corefficient r= -0.09) and higher level of education (P=0.002;r=13). It was not significantly associated with gender (P=0.95), lens pseudoexfoliation (P=0.95), intraocular pressure (P=0.09), presence of diabetes mellitus (P=0.20), and presence of dry eye symptoms (P=0.31).
Prevalence of myopia was lower in in the South Russian UEMS study population than in populations from East Asia. As in East Asia, longer axial length was correlated with higher educational level and younger age.
