The most effective surgical technique for trachiasis involves a full-thickness tarsal plate incision and 180-degree rotation of the lid margin. Community-based delivery and double-sided sticking plaster for temporary relief are also recommended.

Area of Science:

  • Ophthalmology
  • Public Health
  • Infectious Diseases

Background:

  • Trachoma is a significant cause of preventable blindness globally.
  • The World Health Organization (WHO) advocates the SAFE strategy (Surgery, Antibiotics, Facial cleanliness, Environmental hygiene) to combat trachoma blindness.

Purpose of the Study:

  • To review the evidence on the effectiveness of various interventions for treating trachoma trichiasis.

Main Methods:

  • Systematic review of randomized controlled trials (RCTs) identified through extensive database searches (CENTRAL, MEDLINE, PubMed, EMBASE, LILACS) and manual searches.
  • Independent assessment of trials by two reviewers, with data verification through author contact.

Main Results:

  • Seven studies met inclusion criteria, evaluating surgical techniques, temporary measures, and delivery methods.

  • Full-thickness tarsal plate incision with 180-degree rotation of the lid margin appears most effective for trichiasis.
  • Double-sided sticking plaster is more effective than epilation for immediate management, though requiring frequent changes.
  • Community-based surgery is as safe and convenient as health center-based surgery.
  • No difference in outcomes was found between surgery performed by ophthalmologists versus integrated eye workers, or with concurrent azithromycin administration.

    • Conclusions:

    • No reviewed interventions definitively prevent blindness from trichiasis.
    • The preferred surgical technique for trachiasis is full-thickness tarsal plate incision and 180-degree lid margin rotation, ideally performed in the community.
    • Double-sided sticking plaster offers a more effective temporary solution than epilation.
    • Trachiasis surgery can be effectively performed by ophthalmologists or trained ophthalmic assistants.
    • Adding azithromycin during surgery does not enhance success rates.
