How vision is affected by Parkinson's disease
Parkinson’s disease affects different bodily functions of the patients. Some symptoms may also be milder in one and worse in others. Patients experience tremors, slowed movement, impaired balance and posture, and speech changes. Many patients who have been diagnosed with Parkinson’s have a range of visual problems too. These problems are worsened as patients grow older and gradually impact their daily routine.
Parkinson disease slows down the visual processing of patients. When visual stimuli are complicated, their visual perception declines. They experience difficulty in contrasting or discriminating colors, motion perception, facial recognition, and visual acuity. At the advanced stage, they may suffer from chronic visual hallucinations. These are also only some of the possibilities as each patient has varying visual symptoms.
