What is Dry Eye?


Dry eye, or dry eye syndrome (DES), is a condition that affects millions of people. It is often a normal part of the aging process, and is more common in older people. Other causes include exposure to environmental irritants, injuries to the eye or certain health conditions, such as diabetes, thyroid deficiencies, autoimmune disorders (i.e., Sjogren’s Syndrome, Rheumatoid Arthritis, Lupus or HIV), Bell’s Palsy and Myasthenia Gravis.

Dry eye syndrome is literally the eye’s inability to lubricate and tear correctly. Strangely enough, some people who have dry eye syndrome actually tear excessively because the pH of their tears is altered so that their eyes feel dry and itchy.

The use of certain medications can also alter the eye’s ability to remain well lubricated. Some of the most common medications are:

  • Antihistamines
  • Decongestants
  • Blood pressure medications
  • Antidepressants
  • Anti-anxiety medications

  • Redness
  • Itching
  • Burning
  • Blurry vision
  • Excessive watering
  • Grittiness
  • Eye fatigue

Dry Eye Treatment

Your doctor may prescribe one or more of the following treatments for dry eye syndrome:
  • Artificial tears
  • Long-lasting lubricating gels
  • Ointments
  • Temporary or permanent plugging of the tear ducts, in addition to replacing the tears with drops or ointments
  • Change in medications that can cause dry eye
  • Prescription medication for chronic, moderate to severe dry eye (e.g., Restasis)
If you have tried these treatments for dry eye and not gotten relief, you may have a chronic condition known as Evaporative Dry Eye. This is caused by a condition known as Meibomian Gland Dysfunction (MGD). Click here to learn more about MGD and how the physicians at Woolfson Eye Institute can help treat your dry eyes.
