To evaluate the efficacy of circumferential viscodilation and tensioning of Schlemm’s canal (canaloplasty) in lowering intraocular pressure in our patient population.
Medical records of each patient undergoing canaloplasty in our institution to date were retrospectively reviewed. Main outcome measures included intraocular pressure (IOP) pre-operatively and at 1, 3, and 6 months post-operatively, number of IOP lowering medications required at each visit, and the need for further surgery.
Our cohort consists of the first 46 patients undergoing canaloplasty in our institution. The mean baseline IOP was 22.9 +/- 7.6 (SD) mmHg on a mean of 2.8 +/- 0.8 (SD) medications per patient. The mean IOP at 1 month (N=46) was 16.8 +/- 6.3 mmHg; at 3 months (N=41) 14.9 +/- 5.5 mmHg; and at 6 months (N=31) 14.9 +/- 4.8 mmHg. This represents a 26.6% reduction of IOP at 1 month, and a 34.9% reduction in IOP at 3 and 6 months. The number of medications decreased to a mean of 1.0 +/- 1.2 per patient at 6 months, a 64.3% reduction. Few patients required repeat surgery for IOP control, with 4 patients (8.7%) receiving a Baerveldt implant and 2 patients (4.3%) receiving an Ahmed implant.
Canaloplasty is an effective surgical procedure for the lowering of intraocular pressure in our patient population at 6 months. Further follow-up is needed to assess the long-term efficacy of this procedure.
