Trabeculotomy is effective for juvenile primary open-angle glaucoma (JPOAG), achieving good intraocular pressure control and preventing visual field progression. Younger patients under 40 experienced a 100% success rate in this long-term study.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Surgical Interventions

Background:

  • Juvenile primary open-angle glaucoma (JPOAG) presents unique challenges due to early onset.
  • Long-term efficacy data for surgical interventions in JPOAG are crucial for treatment planning.

Purpose of the Study:

  • To evaluate the long-term outcomes of trabeculotomy in patients with JPOAG.
  • To compare the effectiveness of trabeculotomy with filtering surgery in this population.

Main Methods:

  • A follow-up study of 16 eyes in 11 JPOAG patients (diagnosed aged 10-45).
  • Mean follow-up duration of 7 years (range 1-18 years).
  • Assessment of intraocular pressure (IOP) and visual field defects, with and without medical treatment.

Main Results:

  • 88% of eyes achieved an IOP of 21 mm Hg or less post-surgery.
  • 100% success rate observed in patients younger than 40 years.
  • No progression of visual field defects noted after IOP normalization.

Conclusions:

  • Trabeculotomy is a recommended surgical option for JPOAG, potentially superior to filtering surgery due to age-related success rates.
  • Ocular hypertension may be the primary risk factor in JPOAG, as indicated by functional results after IOP normalization.
