Prevalence and associated factors of osteoarthritis in the Ural Eye and Medical Study and the Ural Very Old Study.

To determine the prevalence of osteoarthritis and its associated factors in populations from Russia. The population-based Ural Eye and Medical Study (UEMS) and the population-based Ural Very Old Study (UVOS) were conducted in a rural and urban region in Bashkortostan/Russia and included participants aged 40+ and 85+ years, respectively.

Purpose: To assess the prevalence of reticular pseudodrusen (RPD) and their determinants.

Methods: The Population-based Ural Eye and Medical Study conducted in Bashkortostan/Russia included 5899 participants aged 40+ years. Presence of RPDs was assessed on conventional colour fundus photographs, red-free fundus images and optical coherence tomographic images.

Ankle-brachial index and ocular diseases in a Russian population.

Background: To assess potential associations between the ankle-brachial blood pressure index (ABI) and ocular disorders.

Methods: In the population-based cross-sectional Russian Ural Eye and Medical Study including 5,899 (80.5%) out of 7328 eligible participants aged 40+ years, the participants underwent a series of ocular and medical examinations including measurement of ABI.

Axial length and its associations in the Ural Very Old Study.

To assess the distribution of axial length as surrogate for myopia and its determinants in an old population, we performed the Ural Very Old Study as a population-based cohort study. Out of 1882 eligible individuals aged 85 + years, the Ural Very Old Study performed in an urban and rural region in Bashkortostan/Russia included 1526 (81.1%) individuals undergoing ophthalmological and medical examinations with sonographic axial length measurement.

Prevalence Factors Associated With Vision Impairment and Blindness Among Individuals 85 Years and Older in Russia.

Importance: Visual performance is important for quality of life. However, vision impairment among adults 85 years and older has not been intensively examined.

Objective: To assess the prevalence of mild vision impairment (VI), moderate to severe vision impairment, and blindness and the factors associated with these conditions among a population 85 years and older.

The prevalence of dry eye in a very old population.
