Alhassan M (2022) Sensory and motor visual functions in Parkinson’s Disease with respect to freezing of gait symptoms. J Ophthalmol & Vis Sci 7(2):1069.
Objective: This review article summarizes the results from previous studies focusing on visual functions in Parkinson’s Disease patients.
Summary: Freezing of gait (FOG) is considered to be a motor disorder symptom that affects some Parkinson Disease (PD) patients; however, it is hypothesized that sensory systems may also be involved in FOG. Visual functions include high contrast visual acuity, low contrast visual acuity, contrast sensitivity, Vernier acuity, mesopic vision, stereopsis, motion perception, and vergence eye movements and are all affected in PD patients with FOG patients having more deficits in some of these functions. FOG patients also had impairments in non-dopaminergic mediated functions which suggests greater impairment in two functions that involve cholinergic neurotransmitters. 192-IgG-SAP (Cat. IT-01) was used to create a PD rat animal model to study the contribution of the cholinergic system to motor functions. It was found that the fall rates were more frequent in rats, that were injected with dual 192 IgG-saporin /6-hydroxydopamine (6-OHDA) than rats with either isolated cholinergic or isolated dopaminergic lesions.
