Conjunctival autografting and mitomycin C treatments show the lowest pterygium recurrence rates. Conjunctival autografting offers superior results despite being more complex, making it the recommended pterygium surgery technique.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Ocular Surface Disease

Background:

  • Pterygium is a common ocular surface condition.
  • Various surgical techniques exist for pterygium excision, each with varying recurrence and complication rates.

Purpose of the Study:

  • To compare the efficacy of four pterygium surgery techniques: bare sclera, mitomycin C, conjunctival flap, and conjunctival autograft.
  • To evaluate complication and recurrence rates associated with each surgical method.

Main Methods:

  • A comparative study involving 77 eyes from 60 patients undergoing pterygium excision.
  • Techniques included bare sclera (21 eyes), mitomycin C (20 eyes), conjunctival flap (18 eyes), and conjunctival autograft (18 eyes).
  • Follow-up ranged from 6 months to 2 years to assess outcomes.

Surgical Correction for Pediatric Epiblepharon and Trichiasis

Published on: July 8, 2025

Main Results:

  • Recurrence rates were highest in the bare sclera group (38.09%) and lowest in the conjunctival autografting group (approximately 16.67%).
  • Mitomycin C and conjunctival flap groups showed recurrence rates of 25% and 33.33%, respectively.
  • No major vision-threatening complications were reported across all surgical groups.

Conclusions:

  • Conjunctival autografting demonstrated the lowest recurrence rate and superior cosmetic and surgical outcomes.
  • While more complex, conjunctival autografting is recommended due to high recurrence rates of other methods and potential mitomycin C complications.
  • Mitomycin C also showed favorable recurrence rates but carries potential risks for benign conditions.
