Dry Eye Disease
Dry eye is a multi-factorial disease of the ocular surface that results in symptoms of discomfort, tear film instability, and potential damage. A new gold standard test for osmolarity is an important diagnostic tool not widely available. A treatment plan is individualized to reduce symptoms and improve overall eye health and vision. Clinical studies are ongoing.
Due to its complex nature, dry eye disease is often times under diagnosed. When it is diagnosed, accuracy is difficult since common dry eye symptoms can mimic the same symptoms as those of other ailments, like ocular allergies.
There are two predominant forms of Dry Eye – aqueous and evaporative. Evaporative dry eye, which affects 65% of sufferers, is caused by meibomian gland dysfunction (MGD) or blocked glands that create a deficiency in the oil layer of the tear film. This can be the beginning of other dry eye disease problems including damage to the cornea and sight-related issues.
Tears are made up of three layers
