People with Parkinson's disease are more likely to suffer from vision problems

Scientists at the University Medical Centre in Redbud, the Netherlands, have found that Parkinson's patients are more likely to have visual disturbances that interfere with normal daily activities and adversely affect their quality of life. The results of the study, published in the journal Neurology, complete information about the development of the neurodegenerative disease.

Parkinson's disease causes motor disorders, tremors, problems with balance, navigation, and others. Scientists from the Netherlands argue that the disease can also cause pathological changes in visual perception.

They interviewed 1098 patients, whose average age was 70 years. The results showed that over 82% of the participants had at least one ophthalmological symptom: e.g. double vision, blurred vision, tearfulness, etc. Moreover, 52% of patients reported that they could not read due to vision problems, 33% said they could not drive a car for this reason, and 28% could not watch TV or work at a computer normally.

The authors of the study note that ophthalmological symptoms are often underestimated or ignored by specialists in the treatment of the disease. However, they argue that vision correction could smooth out other Parkinson's symptoms, for example, improve patients' navigation abilities.

The results add new facts about the course of Parkinson's disease and the effect of its symptoms on patients' daily activities. "Since almost 80% of visual disturbances are treatable or can be prevented at all, timely recognition is essential," the researchers write.
