Tears help in the protection of eyes. Dry eyes may be due to increased evaporation of tears or its decreased production

Decreased tear production

Decreased production of tears also known as Keratoconjunctivitis sicca. Can be due to:

  • Conditions like Thyroid disturbances, diabetes, SLE, Sjogren’s syndrome, thyroid disorders, etc
  • Drugs eg; decongestants, HRT, Antihistamines, antidepressants etc
  • Age
  • Disruption of lacrimal glands due to radiation or inflammation.

Increased tear evaporation

May be due to:

  • Blinking eyes very less
  • Dry, windy or smoky atmosphere

Some complications may occur like:

Diagnosis requires the following:

  • A detailed examination of eye
  • Schirmer test (tear measurement)
  • Composition of tears

For treatment of dry eyes, we first have to treat the underlying cause; any disease or syndrome. For milder cases eye drops can also be used. Some medications used are:

  • Hydroxypropyl cellulose.
  • Corticosteroids
  • Oral Antibiotics
