Ophthalmic epidemiology·2026

This study found a modified grading scheme for trichiasis of the upper eyelid demonstrated high inter-observer agreement. This reliable system aids ophthalmic professionals in assessing severity and planning surgical interventions for trachomatous trichiasis.

Area of Science:

  • Ophthalmology
  • Public Health

Background:

  • Trachomatous trichiasis is a leading cause of preventable blindness.
  • Accurate grading is essential for effective surgical management and preventing vision loss.

Purpose of the Study:

  • To evaluate the inter-observer agreement of a modified grading scheme for trichiasis of the upper eyelid.
  • To assess the reliability of a new system for classifying trichiasis severity.

Main Methods:

  • A novel grading system was developed, categorizing trichiasis into three severity levels (TT1, TT2, TT3) and four anatomical locations for TT1.
  • Ophthalmic professionals assessed trichiasis patients using this modified grading scheme.

Main Results:

  • High inter-observer agreement was observed for simple trichiasis (TT1) and entropion (TT2) using Cronbach's alpha (0.84).

  • Agreement within sub-grades was also high (0.86).
  • Weighted Kappa values indicated good to very good agreement for main and sub-grades.

    • Conclusions:

    • The modified grading scheme for trichiasis is highly reliable and easily applicable by various ophthalmic professionals.
    • The scheme's progression from simple to severe forms aids in determining surgical correction extent.
    • This reliable grading system can improve surgical outcomes for trachomatous trichiasis.
