title: Long-term Surgical Outcomes of 180-Degree Suture Trabeculotomy in Korean Patients With Primary Congenital Glaucoma.
abstract: To investigate the surgical outcomes of 180-degree suture trabeculotomy in Korean patients with primary congenital glaucoma (PCG).
  
  
  
  This retrospective study included 21 eyes of 17 children with PCG who underwent 180-degree suture trabeculotomy as a first surgical procedure. Surgical success was defined as (1) an intraocular pressure (IOP)<22 mm Hg with or without medication; (2) no additional intraocular surgery; and (3) no evidence of progressive optic disc cupping. The main outcome measure was the success rate of 180-degree suture trabeculotomy. Secondary outcome measures were IOP, number of glaucoma medications, and occurrence of complications.
  
  
  
  Of the 21 eyes included, 18 (85.7%) were classified as having achieved success at the final visit (mean last follow-up or failure time, 54.91±45.68 mo). Median age at surgery was 11.97 months with mean IOP 29.8±9.6 mm Hg, on average of 1.52 medications. The mean IOP at the final visit was 16.9±5.6 mm Hg on an average of 0.38 medications. The surgical success rate of 180-degree suture trabeculotomy at 1, 3, and 5 years was 95.0%, 87.7%, and 78.9%, respectively (Kaplan-Meier analysis). Three eyes underwent second operations and the mean time to failure was 29.39±19.75 months. Hyphema was observed in 10 eyes, but it cleared up within 7.6 days.
  
  
  
  The 180-degree suture trabeculotomy performed for PCG had a significant IOP-lowering effect and caused no remarkable complications.
