Is dry eye disease common in people with Parkinson’s?
Dry eye disease can involve symptoms such as a lower blinking rate and typically occurs when the eyes are not effectively moistened by tears – leading to discomfort and possible vision loss. Now, a recent study from Japan has investigated the previously underexplored relationship between dry eye disease and Parkinson’s. As part of their research, the team analysed 13 studies published between 2004 and 2022, which involved more than 1,500 people with Parkinson’s. Five of the reports highlighted the prevalence of dry eye disease in people with the condition – with 61% experiencing symptoms. “Our findings emphasize the need for clinicians to be vigilant of the presence of dry eye disease when managing [people with Parkinson’s],” the researchers wrote. However, they noted that more research is needed – especially “future large-scale studies” – to help understand the relationship between dry eye disease and the condition.Read more
