"Characterization of Visual Problems in Patients With Parkinson's Disease and Application of an Oculomotor and/or Perceptual Therapy Program"

University of Valencia·observational·Posted Sep 11, 2023·Updated May 4, 2026

In Brief

An observational study evaluating Clinical measurements and Oculomotor or perceptual therapy for Parkinson Disease. Completed, enrolled 160 participants across 1 site.

Detailed Summary

Parkinson's disease (PD) is the second most common neurodegenerative condition worldwide, characterised by motor symptoms, but with other symptoms such as visual impairment. The aim is to compare visual function between PD patients and healthy subjects in order to adequately characterise the visual capabilities of the PD population and perform oculomotor or perceptual therapy to find optometric solutions to slow down the visual impairment they suffer from or minimise their visual symptoms. In the first phase, non-invasive tests will be carried out, such as measuring visual acuity, refraction, pupil diameter in different lighting conditions, sensory dominance, contrast sensitivity, colour vision, stereopsis, reading speed, binocular vision, eye movements and influence on quality of life. In the second, visual oculomotor or perceptual exercises will be performed in a group of PD patients to assess whether there is stabilisation of impairment or improvement of these visual skills. These will be performed in a non-invasive way using simple and easy-to-use instruments or an application on an electronic device could be used. Finally, in the third phase, those visual skills that have been treated will be re-evaluated to assess possible changes, compared with a group of PD patients who have not undergone the visual exercises.
