What is Dry Eye?

Houston | LASEK | Dr. Yee | Dry EyeDry eye is a chronic disease in which the body does not make enough normal tears to keep the eye lubricated and comfortable.  While treatable, this condition can cause a great deal of discomfort, pain and hardship for dry-eye sufferers.

Evaporative dry eye accounts for the vast majority of dry eye cases and is caused by blockages in the meibomian glands located in your eyelids. This condition of obstructed glands is known as Meibomian Gland Dysfunction or Meibomian Gland Disease (MGD). These glands are responsible for creating the lipid (oil) layer of tears. When these glands are not working as they should, you do not have enough tear film oil and your tears evaporate too quickly. An inefficient oil layer can cause your tears to evaporate four to 16 times faster than normal. So it is possible for your eye to produce enough water but because of  poor or abnormal oil production, you still have the dry eye causing dry eye complaints and damage to the ocular surface. And with more and more of us using computers regularly, Dr. Yee has studied the effects extensive computer usage has on our eyes and hypothesizes that computer users are at increased risk for developing MGD due to the significant decrease of the blink rate over time — a condition known as Computer Vision Syndrome. If your MGD is severe, you should also have a lipid level checked.  Dr. Yee has published and the first to describe an association of MGD and high blood total cholesterol.
