About Dry Eye Disease

Dry Eye Disease (also called dry eye syndrome, dry eye, or dry eyes) is a chronic condition caused by a lack of adequate tear production. To those who have it, Dry Eye Disease is a nagging discomfort that won’t go away.

In the past 10 years significantly more has been learned about this common, yet frequently under-diagnosed, condition. It isn’t life-threatening, but it can be debilitating. It has numerous causes, symptoms, and diagnostic challenges. Dry Eye Disease isn’t the simple irritation it was once thought to be. We now know that it is complex and requires specialized focus.

This has led to tremendous advancements in how Dry Eye Disease is identified, diagnosed, and managed. It is also why Dry Eye Institutes of America™ was founded. We are devoted to making the latest advancements more accessible to patients and proud to be one of the first in the U.S. to offer this level of specialty. We are also focused on making sure that our patients easily understand Dry Eye Disease, starting here.

Tear Film DiagramDry Eye Disease Overview
Dry eye disease occurs when your tear film breaks down (the thin film of tears that coats the surface of your eyes). Tear film is designed to do much more for your eyes than keep them moist and comfortable. It creates a smooth surface for light to pass through the eye. It nourishes the front of your eyes, and protects against injury and infection.

Your tear film is made up of three layers which are critical to how your eye functions:

  1. The top (lipid) layer is made of oil to seal the tear film and prevent evaporation.
  2. The middle (aqueous or water) layer is made of water to clean the ocular surface and prevent it from drying. This layer is also important for providing nutrients, elements and proteins for corneal wound repair and resistance against infection.
  3. The bottom (mucin) layer is made of mucous to help tear film adhere to the eye, as well as provide tear film stability.

Types of Dry Eye Disease
The are two primary types of Dry Eye Disease. Patients most often suffer from one or the other, but it’s not uncommon for both to be present at the same time. At Dry Eye Institutes of America™, we use today’s most sophisticated technology to test, diagnose and treat for either or both of the following types:

Evaporative Dry Eye is an inflammation of the meibomian glands located in the eyelids. Meibomian glands make the lipid, or oily, part of your tears that slow evaporation to keep the tear film stable. Evaporative Dry Eye is now considered the most common type of Dry Eye Disease.

Aqueous Tear-Deficient Dry Eye happens when the lacrimal glands don’t produce enough of the watery (aqueous) layer of tears your eyes require. This is necessary to maintain a healthy eye surface.

Dry Eye Disease Today
We know more about how to diagnose and treat this condition than ever before. We also know that Dry Eye Disease has increased dramatically. In short, Dry Eye Disease today is tied to the way we live and the world in which we live. The environment is changing. Our jobs, the way we communicate and find information has us constantly in front of computers and smartphones. We are taking more medications and our aging population is growing. All of these can contribute to Dry Eyes.

Yet our changing world has also brought forth innovation for more effective ways to prevent and treat Dry Eye symptoms. As Dry Eye treatment evolves, Dry Eye Institutes of America™ is uniquely committed to evolving with it to increase each patient’s quality of life.
