ABSTRACT: Background and purpose
Visual dysfunction is a non-motor symptom of Parkinson disease (PD), but its prevalence is unknown as population-based data on the epidemiology of visual symptoms in PD are lacking. The objective was to determine the prevalence of visual dysfunction in PD.Methods
This was a cross-sectional analysis of data from adults ?50 years old in the Survey of Health, Ageing and Retirement in Europe (SHARE), a multinational population-based health survey of adults living in one of 27 European countries and Israel. PD diagnosis was self-reported. Impairment in overall, distance or near eyesight was defined as a score of 4 or 5 on a 1-5 scale. Adjusted logistic regression was used to determine the association between PD and self-reported vision.Results
There were 115 240 age-eligible participants in the SHARE study (mean age 64.3 years, 54% female), of whom 1438 (1.25%) reported a diagnosis of PD. In adjusted logistic regression models, PD was associated with increased odds of impaired overall [odds ratio (OR) 2.67, 95% confidence interval (CI) 1.91-3.72], distance (OR 2.55, 95% CI 2.04-3.19) and near (OR 2.07, 95% CI 1.69-2.55) eyesight. Individuals with PD were also less likely to report having an eye examination within the previous 2 years (OR 0.59, 95% CI 0.38-0.92), but this did not remain statistically significant after adjusting for confounders (OR 0.76, 95% CI 0.47-1.24).Conclusions
Visual dysfunction is significantly more common in PD than in the general adult population. Visual symptoms are a potentially under-recognized and under-treated source of reduced quality of life in PD patients that require further attention and study.
