Neurorehabilitation of Oculomotor Dysfunction in Patients with Parkinson’s Disease

Oculomotor dysfunction is an eye movement disorder frequently experienced in patients with Parkinson’s disease. While this neurodegenerative disorder is often characterised by tremors, rigidity and slow movement, many patients tend to experience visual symptoms during its early stages and this can exacerbate cognitive symptoms when visual tasks become more demanding. This review provides an update on the recent advances in the neurorehabilitation of oculomotor dysfunction, and it uses a sensory-motor integration framework for understanding the vision-related symptoms and the functional challenges imposed on the patient’s activities of daily living. This is categorized in terms of visual sensory, visual motor, visual perceptual, cognitive processing, and psychosocial challenges, and this understanding is vital for accurate diagnosis, monitoring, and implementing effective strategies to improve their visual function and overall quality-of-life. By fostering interdisciplinary collaboration, healthcare professionals can take proactive steps to address the vision-related challenges faced by patients with Parkinson’s disease and effectively manage the challenges faced by patients with Parkinson’s disease.
