To assess prevalence and associations of pseudoexfoliation in a Russian population.
The population-based Ural Eye and Medical Study was carried out in a rural and an urban area in the region of Ufa / Bashkortostan 1400 km East of Moscow. Out of 7328 eligible individuals aged 40+ years, 5,899 (80.5%) individuals participated and underwent an ocular and general examination. After medical dilation of the pupil, the presence of pseudoexfoliation was determined by slit-lamp based biomicroscopy.
Examination data were available for 5779 (98.0%) individuals, while 39 eyes were pseudophakic or aphakic and 81 eyes could not be examined for pseudoexfoliation. Mean prevalence of pseudoexfoliation was 204/5779 or 3.53% (95% confidence interval (CI): 3.05,4.01). It increased from 0.2% (95%CI:0.00,0.06) in the age group of 40-44 years, to 1.5% (95%CI:0.7,2.3) (age: 50-54 years), 6.1% (95%CI:4.4,7.8) (age: 65-69 years) and to 8.0% (95%CI: 5.3,10.7) in the age group of 75+ years. In multivariate analysis, higher prevalence of pseudoexfoliation was associated with older age (P<0.001; odds ratio (OR): 1.07;95%CI:1.06,1.09), Russian ethnicity (versus Tartars, Bashkirks and others) (P=0.03;OR:1.41;95%CI:1.03,1.92) and higher intraocular pressure (P<0.001;OR:1.09;95%CI:1.06,1.12), while it was not significantly associated with gender (P=0.68), systolic (P=0.58) or diastolic (P=0.39) blood pressure, prevalence of diabetes mellitus (P=0.31), axial length (P=0.11), or lens thickness (P=0.23).
The prevalence of pseudoexfoliation in this population from Russia with an age of 40+ years was 3.5%. It strongly increased with older age and was more common in Russians than non-Russian. It was not significantly associated with axial length, diabetes mellitus and blood pressure.
