Dry Eye

About Dry Eye

Dry eye disease is a disorder of the tears and ocular surface. It is caused by a lack of sufficient lubrication and moisture on the surface of the eye. Often it is when glands near the eye don't produce enough tears, or the glands oil output is disturbed, leading to excessive evaporation of the tears. This is considered to be the primary cause or a contributing factor in most cases of dry eye.

The prevalence of dry eye disease rises with increasing age and it is more likely to affect women. 

Symptoms include:

  • Dryness
  • Irritation
  • Foreign body sensation
  • Itching
  • Red eyes
  • Light sensitivity
  • Pressure behind the eye

Treatment 

Tests can determine both the moisture levels, quantity and the quality of the tears.

A variety of approaches can be taken including treatment of eye inflammation, tear stimulation, increasing tear retention, eyelid cleansing and avoidance of exacerbating factors.

For mild and moderate cases, supplemental lubrication is the most important part of treatment.
