A dry eye, referred to as Keratoconjunctivitis Sicca, is one without enough tears.
This deficiency gives rise to chronic irritation, which can cause damage to the cornea and in severe cases corneal scarring. Often there is a burning or gritty feeling and itchy discomfort of the eyes.
There may be episodes of excessive tearing, mucous discharge or blurred vision.
This condition can arise from a number of things, e.g.
- Lack of tear production/poor tear quality
- Natural aging process
- Sun, wind, smoke, air-conditioning
- Rheumatoid arthritis, menopause
Dry Eye Treatment
Once general disease is excluded as a cause, the most common form of treatment for dry eyes are artificial tears; solutions and ointments.
For application of drops: -
- Wash your hands thoroughly before you take the cap off the bottle of drops.
- Tilt your head back up and look up.
- Gently pull your lower lid down to form a 'pocket'.
- Hold the bottle between thumb and forefinger and squeeze the bottle gently to administer one drop at a time into the pocket formed by the lower lid. Only put the prescribed number of drops in your eye(s).
For application of ointment: -
- Wash your hands thoroughly before you take the cap off the tube.
- Tilt your head back.
- Gently pull down your lower lid to form a pocket under your eye - Gently apply a small strip (about l/2cm-lcm) of ointment into the pocket.
