What is Dry Eye Syndrome?
Dry Eye Syndrome is an inflammatory condition of the front of the eyes. When the eyes become dry, they become inflamed and release inflammatory mediators into the tears. These then cause inflammation of the cornea, conjunctiva, and lacrimal gland.
They also desensitize the corneal nerves that send impulses to the brain that tell it to lubricate the eye. This results in an eye that feels scratchy, sandy, burning, teary, achy, as well as tender or as if there is pressure behind the eye. This can also make the vision blurred or fluctuate when reading, using the computer, or driving.
This condition is seen in up to 20% of women and 7% of men. There is thought to be a hormonal link to this condition.
