Natures Tears® EyeMist® - Dry Eye Definitions - Denervation


Denervation: Dry eye is often associated with a decrease in nerve stimulation between the cornea and lacrimal glands, possibly resulting from denervation (loss of nerve function). Even though one may feel discomfort and even pain from dry eye, corneal sensitivity actually decreases. Desensitization could negatively impact the reflex to maintain tear flow.
