title: Long-term results of ab externo trabeculotomy for glaucoma secondary to chronic uveitis.
abstract: OBJECTIVE
  To present the long-term results of ab externo trabeculotomy in the management of glaucoma secondary to chronic uveitis.
  
  
  METHODS
  In this retrospective single-centre case series, medical records of patients with glaucoma secondary to chronic uveitis, who underwent ab externo trabeculotomy, were evaluated. Two definitions of success were used: intraocular pressure (IOP) 6 ≤ IOP ≤ 21 mmHg (success 1) or 6 ≤ IOP ≤ 21 mmHg and at least 25 % reduction from baseline (success 2). Success was complete when no additional medication was required or qualified when additional medication or cycloablative procedures were required to achieve the specific IOP definition.
  
  
  RESULTS
  Twenty-two eyes of 18 patients were included. After 3 years, median IOP decreased from 27 mmHg [range 17-43 mmHg, mean 27.5 mmHg, 95 % confidence interval of the mean (CI) 24.5-30.5 mmHg] to 15 mmHg (range 9-19 mmHg, mean 14.5 mmHg, CI 13-16.1 mmHg). Complete and qualified success 1 was 23 and 45 % after 3 years, respectively. For success 2, the rates were 23 and 32 %, respectively. Hyphema was the most common complication, which resolved completely within 1 month after surgery without further intervention.
  
  
  CONCLUSIONS
  Trabeculotomy ab externo was moderately successful in glaucoma secondary to chronic uveitis after 3 years. No sight-threatening complications were observed during the follow-up period.
