Retina Changes May Predict Parkinson's Course
Changes in the retina might predict disease progress in patients with Parkinson's disease, according to a new study presented here at the North American Neuro-Ophthalmology Society 2015 Annual Meeting. Previous research has established links between Parkinson's disease and changes in the human retina. Neurons that produce dopamine are present in the human retina and dopamine is affected in Parkinson's.
@bipasha People with Parkinson's disease often have visual deficits, and previous studies have revealed thinning of the peripapillary retinal nerve fiber layer and decreased electrical activity at the fovea in these patients. There was no significant difference in macular thickness or volume, and color vision, intraocular pressure, anterior segment, and fundus were all normal in the two groups.
