Visual disturbances in Parkinson's patients could occur more frequently

Visual disorders in Parkinson's such as blurred vision, dry eyes, disturbed depth perception and adaptation to poor lighting conditions are widespread among people with this disease. This emerges from a recent study that found that such problems can affect a person's daily activities.

It is particularly important for patients with Parkinson's disease to have the best possible eyesight. This can help to balance the movement problems caused by the disease and reduce the risk of falling. This is what the study author Carlijn Borm from the medical center in Nijmegen, the Netherlands claims.

“Our study not only found that people with Parkinson's disease had eye problems. Most of them go beyond the aging process. However, these problems could also affect your daily life. However, most eye problems are treatable. For this reason, it is important that we examine and treat the people affected as often as possible. ”

848 patients participated in the study. They had symptoms for an average of seven years. The researchers compared the first group to 250 other people without the disease. Both groups had an average age of 70 years. The subjects filled out a questionnaire on vision and eye problems. Participants also answered whether eye problems interfere with their daily activities, such as driving, working on computers, walking, or personal hygiene.

The scientists found that 82% of people with Parkinson's reported one or more eye problems. This was compared to 48% of people without the disease. The average score on the questionnaire was 10 points for people with Parkinson's vision problems compared to two points for people without disease. The researchers also found that eye problems affected daily life in 68% of sick patients, unlike the other 35%.

“Eye problems make it difficult for Parkinson's patients to physically find their way in everyday life. For example, we found that half of the study participants had problems reading and 33% had eye problems that affected driving, ”said Borm. “We should refer people with Parkinson's who express that they have eye problems to a specialist for further evaluation. For those who do not report such problems, the use of a screening questionnaire can be a recognition for timely treatment and thus may improve the quality of life. “

One limitation of the study was that people with vision problems may be more likely to respond when asked if they would like to participate in the study, which may lead to an overestimation of the eye problems.
