OBJECTIVE: To analyze trends in the surgical management of @entity726 in Ontario over the past 2 decades. DESIGN: Retrospective analysis of health records. METHODS: Ontario Health Insurance Plan billing service claims between 1992 and 2012 were analyzed for the yearly number of @entity726 laser and incisional surgical procedures. The yearly number of Ontarians with @entity725 ( @entity725 ) was estimated by applying composite prevalence curves to published population data and the yearly number of procedures per 1000 Ontarians with @entity725 was calculated. RESULTS: Per 1000 @entity1 with @entity725 , laser trabeculoplasty (LT) rates increased nearly 2-fold (185%) from 1992 to 2012, with the rates stabilizing between 2008 and 2012, and total @entity726 filtration procedure (GFP) rates (trabeculectomy, aqueous shunts, and combined GFP and @entity231 extraction) in 2012 were similar to those in 1992, with a peak rate noted in 1996. Shunts represented 0.9% of GFP in 1992 and 33% in 2012. Data for combination codes billed on the same day for the same @entity1 were available from 2000. From 2000 to 2012 the rates of trabeculectomy alone remained unchanged, the number of aqueous shunts alone increased more than 5-fold, combined trabeculectomy and @entity231 extraction decreased 81%, whereas combined shunts and @entity231 extraction increased from 6 in 2000 to 420 in 2012. Combined aqueous shunts and @entity231 extraction represented 0.4% of combined @entity231 extractions in 2000 and 26.3% in 2012. CONCLUSIONS: Over the past 2 decades there was an overall increase in the rate of LT, no change in the rate of trabeculectomies, and a significant increase in aqueous shunt surgery.
