Summary

Pterygium excision significantly improves tear function and increases conjunctival goblet cell density in patients. This suggests a strong link between pterygium and dry eye disease, with surgery offering relief.

Area of Science:

  • Ophthalmology
  • Dry Eye Research

Background:

  • Pterygium is a common ocular surface condition.
  • Pterygium may be associated with dry eye symptoms and impaired tear function.

Purpose of the Study:

  • To assess the short-term impact of pterygium excision on tear function.
  • To evaluate changes in conjunctival goblet cell density post-pterygium surgery.

Main Methods:

  • Seventy patients with primary pterygia underwent bare-sclera excision.
  • Tear break-up time, Schirmer test, tear-ferning test, and goblet cell density were measured pre- and post-surgery (1 month).

Main Results:

  • Tear break-up time significantly improved (P=0.002).
  • Tear-ferning test results showed significant improvement (P<0.001).

  • Conjunctival goblet cell density increased significantly post-surgery (P<0.001).

    • Conclusions:

    • Pterygium excision enhances ocular surface tear function.
    • The findings suggest a significant association between pterygium and dry eye.
