Dry Eye

What is dry eye?

Dry eye is a common condition that occurs when tears can’t provide adequate lubrication for eyes. The eye fails to produce tears properly or the tears are not of the correct consistency and evaporate too quickly. Additionally, inflammation of the surface of the eye may occur. When severe and left untreated, this condition can lead to pain, ulcers, or scars on the cornea, and some loss of vision. Types of dry eye:
 
  • Aqueous tear-deficient dry eye is a disorder in which the lacrimal glands fail to produce enough of the watery component of tears to maintain a healthy eye surface. 
  • Evaporative dry eye may result from inflammation of the meibomian glands, also located in the eyelids. These glands make the lipid that slows evaporation and keeps tears stable.

 

Risk

  • Old age. Tear production tends to diminish as you get older. 
  • Gender. A lack of tears is more common in women, especially if they experience hormonal changes due to pregnancy, using birth control pills or menopause.
  • Eating a diet that is low in vitamin A or low in omega-3 fatty acids
  • Wearing contact lenses
 
 
Diagnosis
 
  • A comprehensive eye exam includes a complete history of your overall health and your eye health.
  • Measuring the volume of your tears. Your doctor may measure your tear production using the Schirmer test
  • Determining the quality of your tears. Other tests use special dyes in eyedrops to determine the surface condition of your eyes. 
 
 
Treatment 
Treatments aim to reverse or manage a condition or factor that is causing dry eyes. Other treatments can improve tear quality or stop tears from quickly draining away from the eyes.
