This 4-page educational supplement (PDF) confirms the frequency of oculomotor and opthalmic complaints in PD. Referral to a neuro-ophthalmologist, either a neurologist or ophthalmologist with additional training in problems of the eye and nervous system, is recommended. There is an explanation of eye movements, external eye disease, and sensory deficits common in PD, as well as a discussion on management of these issues.

This 2-page fact sheet (PDF) explains that bradykinesia may result in several vision changes, as can impaired electrical signals and feedback in the brain. It discusses each visual change and what can be done to help, as well as a brief discussion of glaucoma and PD. Changes to vision may impair mobility and increase risk of falls. Not all vision problems are related to PD.

This webpage explains the visual problems that are due to Parkinson’s disease, the medications used to treat it, or to unrelated conditions of the eye or eyelid. If you have visual problems, don’t assume it is due to either aging or Parkinson’s. Address it with your doctor to maintain your ability to read, drive, and walk steadily to reduce your risk of falling.

This single page resource defines neuro-ophthalmologist and common ophthalmic complaints in Parkinson’s disease. It explains how Parkinson’s disease affects three fundamental types of eye movements, and contributes to external eye disease and sensory deficits. Finally there is a brief discussion of managing these ophthalmic issues.

Only two paragraphs about the loss of smell in Parkinson’s precede nearly a dozen eye problems and vision difficulties for people with Parkinson’s and useful tips for coping with them. Of note is a paragraph suggesting that those with glaucoma may have problems with anticholinergic medication and levodopa.

Retired neurologist and young onset Parkinson’s patient, Dr. Maria De León reminds us that vision is integral to our quality of life and safety, especially with respect to driving. She lists 11 common eye problems with PD, and a few uncommon ones. They may be helped by adjusting medications, with special lenses, or artificial tears. See your doctor to find out.

This webpage identifies six common difficulties with the eyes associated with PD and aging. The webpage offers tips for managing these issues. The uncommon condition of blepharospasm (involuntary closure of the eyes) is addressed along with several potential causes (not related to Parkinson's) and a bit about the botulinum toxin (Botox) injections that treat it.

In this 68-minute webinar, neuro-ophthalmologist Dan Gold discusses common eye movement disorders in Parkinson’s disease and provides practical advice for coping with vision issues at home and with your health care team.

This 6-minute video alternates between an interview with a man and and doctors. The man shares his vision changes due to Parkinson's disease. The doctors explain that the muscles of the eyes develop a tremor in those with Parkinson's disease, causing blurry vision. Parkinson's medication reduces eye tremors by 75-90%, but eye exercises and reading are also beneficial.

In this 1-hour webinar, neuro-ophthalmologist Dan Gold discusses the most common vision conditions in PD, which negatively impact daily function and quality of life, why they occur, and how to address or treat them.

This literature search covering 50 years reviews the range of ocular and visual disorders in patients with PD and classifies these according to anatomical structures of the visual pathway. It discusses six common disorders in more detail, reviews the effects of PD-related pharmacological and surgical treatments on visual function, and offers practical recommendations for clinical management.

The purpose of this paper is to evaluate the effect of dopaminergic medication and deep brain stimulation on ocular function in Parkinson Disease (PD) and to measure vision-elated quality of life in subjects with PD. The conclusion is that convergence ability is significantly poorer in PD subjects in both “on” and “off” states compared with controls, but significantly improves with systemic dopaminergic treatment. Ocular motor function in PD subjects fluctuates in response to treatment, which complicates ophthalmic management. PD subjects have a significant reduction in vision-related quality of life, especially near activities, that it not associated with visual acuity.

This paper is a systematic evaluation of the ocular complaints and ocular finding of 30 PD patients with early untreated PD, and 31 control subjects without neurologic or known ocular diseases. The ocular abnormalities found more commonly encountered by PD patients frequently respond to treatment. Abstract and access to the full article.

This article reviews several papers that have been published describing ophthalmological abnormalities, including problems with visual function, ocular movements, and visual hallucinations, as well as complications of drug therapy or neurosurgical interventions.

An overview of visual problems likely to be encountered in PD. If visual problems are present, they can have an important effect on the quality of life of the patient, which can be improved by accurate diagnosis and where possible, correction of such defects.
