Summary

This study looked at vision problems in people with Parkinson's disease compared to healthy individuals. Researchers tested eye and visual skills, then had some Parkinson's patients do simple eye exercises. The goal was to see if these exercises could slow vision decline or reduce symptoms. The trial involved 160 participants and has already been completed.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Oculomotor or perceptual visual exercises
What this could lead to
If successful, this could lead to simple eye exercises that help stabilize or improve vision in people with Parkinson's disease.
What could go wrong
This is a small, completed study focused on characterization and short-term therapy. The exercises may not provide lasting benefits or work for everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Subjects without neurodegenerative diseases or systemic illnesses or ocular pathologies. * Subjects not taking medication with visual side effects. * Subjects able to perform the tests. * Subjects of similar age and sex as their corresponding Parkinson's patient so that both samples are age and gender matched. * Subjects diagnosed with Parkinson's disease. * Parkinson's patients classified according to the Hoehn \& Yahr Scale. Exclusion Criteria: * Subjects with ocular pathologies (such as Glaucoma, Age-Related Macular Degeneration, Retinopathies, Corneal Opacifications, Senile Cataracts, Severe Palpebral Ptosis) or systemic illnesses that may affect the visual system and alter the results (such as Severe Cardiopathies, Diabetes Mellitus, oncological diseases, systemic tissue disorders, chronic infectious diseases or conditions after organ or tissue transplantation). * Subjects with neurodegenerative or neural diseases other than the study itself, such as Alzheimer's disease, Devic's disease, Huntington's disease, Creutzfeldt-Jakob disease, epilepsy, ataxia, multiple sclerosis or amyotrophic lateral sclerosis. * Subjects taking medication that may alter any visual ability such as anxiolytics, antidepressants, sleeping pills. * Subjects with problems in understanding and following the tests. * Patients who have been previously treated under a vision therapy program.
