Dry eye is a common yet often overlooked complication of Parkinson's disease. Understanding its symptoms and management can enhance your quality of life. Find specialized care for Parkinson's dry eye with practices listed with Specialty Vision.
Parkinson’s disease is primarily known for its motor symptoms, but it also affects the eyes, leading to distressing issues such as dry eye. Dry eye in Parkinson’s can be an early sign, often stemming from a reduced blink rate and disturbances in tear production. Understanding the relationship between Parkinson’s and dry eye is essential for improved quality of life and timely intervention.
People with Parkinson’s often experience dry eye because the disease leads to both decreased tear secretion and a significant reduction in blinking. This slower blink rate means that tears evaporate more quickly from the surface of the eye, leaving it unprotected. As a result, many patients notice discomfort, redness, and a gritty or sandy sensation in their eyes.
The link between Parkinson’s and dry eye lies in the neurodegenerative effects on the pathways that control blinking and tear production. In a healthy eye, blinking spreads a protective tear film that nourishes and lubricates the cornea. However, patients with Parkinson’s may blink only three to four times per minute instead of the typical 14 to 15 times, which compromises the tear film.
Other contributing factors include:
Many symptoms of dry eye overlap with other ocular conditions, making it critical to recognize the subtle signs in patients with Parkinson’s. Common symptoms include discomfort, a gritty or foreign body sensation, blurry vision, and light sensitivity. These signs often worsen throughout the day, particularly in environments with low humidity or strong air currents.
These symptoms can be transient or persistent, and the affected patients might not always connect their discomfort to Parkinson’s disease. Often, patients may first visit an eye doctor for what appears to be standard dry eye before underlying neurological implications are considered.

When dry eye is suspected in a patient with Parkinson’s, comprehensive eye examinations are crucial. These evaluations are designed not only to assess the quality of the tear film but also to rule out any additional ocular complications. Our eye doctors employ various tests to gauge both the amount and the quality of tear secretion, as well as the health of the ocular surface.
These diagnostic tests, when considered alongside the patient’s symptoms and Parkinson’s-related history, enable our eye doctors to tailor a treatment plan specifically for each individual.
Understanding the underlying mechanisms of dry eye in Parkinson’s is key to developing effective treatment strategies. The degeneration of the dopamine-producing neurons in Parkinson’s has a direct impact on the neural circuits that regulate tear secretion and blinking. Alongside these changes, there are additional disruptions in the ocular surface’s natural protective layers.
The tear film of a healthy eye is composed of three layers: a superficial oily layer, an aqueous layer, and a mucus layer. Each plays a pivotal role in maintaining ocular surface health. In Parkinson’s, decreased tear production and impaired blinking disturb the balance among these layers. Over time, this results in a thinner tear film, increased evaporation, and persistent dry eye symptoms.
All these factors create a cascade where the stability of the tear film is compromised, and the ocular surface suffers from continuous irritation and inflammation.
