Abstract
Purpose: :
To report surgical outcomes of patients following canaloplasty, trabeculectomy, and Ex-press shunt implantation at 12 month follow up.
Methods: :
A total of 101 eyes of 90 patients who underwent either canaloplasty (C) (n = 35 ) or trabeculectomy (T) (n= 47) or Express shunt (E) (n= 19) surgery at Tulane in 2007 with 12 months follow up were analyzed in this retrospective study. All surgeries were performed by a single surgeon (RA). Outcomes measured included, postoperative intraocular pressure (IOP), visual acuity, postoperative medications, and complications. Postoperative information were gathered at day 1, week 1, months 1, 3,6, 9, and 12.
Results: :
There were no differences in the baseline characteristics among the groups. The average IOP and the postoperative medications at 12 months measured 12.4 + 3 and 0.6 (C), 10.8 + 3 and 0.3 (T), 19.1 + 6 and 0.8 (E) mm Hg respectively. Visual acuity returned to baseline at 3 months in all patients among the canaloplasty and Ex-press shunt groups and in 90% of the patients in the trabeculectomy group. Choroidal effusions was the most common complication in the trabeculectomy group ( 30%) where as hyphema was the most common complication following canaloplasty (20%). The incidence of surgical intervention among the groups was 14% (C), 40% (T) and 20% (E).
Conclusions: :
Canaloplasty is a promising new technology with comparable results to the gold standard trabeculectomy. The incidence of surgical intervention, and postoperative complications was also less with canaloplasty.
