Tears are necessary for overall eye health: they moisten the eye, keep away harmful debris, help ocular wounds heal, and protect against infection. Up to 30% of Canadians are affected by DES, of which there are two main types:

Frequently Asked Questions

DES can be caused by a multitude of factors, including some of the following:

  • Increased age
  • Female gender
  • Hormonal changes such as menopause
  • Contact lens wear
  • Exposure to dry or dusty environments
  • Presence of autoimmune or connective tissue disorders
  • Long-term use of certain drugs such as antihistamines, nasal decongestants, anti-depressants, retinoids and tranquilizers
  • Inflammation of the conjunctiva
  • Skin conditions that affect the eyelids such as acne rosacea
  • High or low dosage of vitamins
  • Inadequate blinking frequency or magnitude

Since tears are an integral part of a number of ocular processes, DES can present with a wide range of symptoms. Some common symptoms include:

  • Scratchy, sandy sensation
  • Foreign body sensation (or the feeling that something is inside your eye)
  • Excessive tearing
  • Blurry vision
  • Swollen eyelids
  • Red eyes
  • Itching or burning of the eyes
  • Soreness
  • Light sensitivity

DES is a chronic and often progressive condition, and may not be completely curable. However, DES can be managed successfully, resulting in improved comfort and sometimes clearer vision as well. Because DES has a number of causes, treatment options vary from patient to patient, and may include:

  • Artificial tears
  • Lubricating ointments
  • Anti-inflammatory drops
  • Restasis
  • Meibomian gland expression
  • Warm compresses
  • Cliradex cleansing wipes
  • Punctal plugs
  • Nutritional supplements
  • BlephEx
