Dry Eye Syndrome Symptoms

Dry Eye Syndrome Symptoms

Diabetic patients with dry eye may experience the same symptoms as dry eye patients without diabetes. The symptoms consist of

  • A gritty sensation
  • Soreness
  • Decreased visual acuity
  • Photophobia (discomfort or pain to the eyes due to light exposure)
  • Itching
  • Decreased goblet cell density (a loss of cells that produce mucins which act as a defense against ocular surface damage)
  • Corneal sensitivity
  • Excessive tearing
  • Pain

More severe cases may be complicated by corneal lesions, conjunctivitis, keratopathy, and inflammation. Lack of symptoms may result from a reduction in corneal sensitivity caused by diabetic peripheral corneal neuropathy 4.  Even a minimal decrease in corneal sensitivity is sufficient to cause changes in tear secretion.

Dry eye symptoms are typically severe in patients with diabetes whose glycemic control is poor.
