Causes

  • Common in the elderly – reduced tear secretion
  • Persistent gritty sensation without red eye
  • Sjörgen’s syndrome: autoimmune condition, dry eyes and mouth which often accompanies connective tissue disorders e.g. rheumatoid arthritis
  • Diuretics and anticholinergic agents may exacerbate dry eye.

Investigations

  • Staining of the cornea with fluorescin
  • Schrimer’s test (strip of filter paper in fornix, measure advancing edge of tears)

Treatment

  • Artificial tear drops or simple ointments
  • Acetylcysteine drops (in filamentary keratitis)
  • Treatment of blepharitis
  • Temporary punctal plugs or permanent punctal occlusion (tear conservation).
