Purpose

To evaluate intraocular pressure (IOP) control and medication reduction in uncontrolled glaucoma eyes

Setting

International Glaucoma Surgery Registry - IGSR

Methods

Eyes which received canaloplasty performed with an ab-interno approach with the iTrack microcatheter (Nova Eye Medical) with a preoperative IOP above 18mmHg (defined as uncontrolled IOP) were collated from theInternational Glaucoma Surgery Registry - IGSR. Primary endpoints were IOP reduction, control of IOP equal or below 18mmHg, and medication reduction.

Results

162 eyes with a mean preoperative IOP (mmHg) of 23.8±5.5 and on 1.8±1.2 medications were recruited. IOP and medications were reduced to 14.7±4.3 and 15.5±4.8 and 1.2±1.4 and 1.0±1.3 at the 6- (n=82) and 12-month (n=54) follow-ups (p<0.001), respectively. 81.5% of the eyes were controlled (IOP equal or below 18 mmHg) at the 12-month follow up. Mean IOP decreased in 94.4% of the eyes, while the number of medications decreased in 59.3% of the eyes, stayed the same in 31.5%, and increased in 9.3% of the eyes. Potentially related adverse events were: cystoid macular edema (2/162); hyphema >10% anterior chamber (3/162), and intraocular inflammation/uveitis (1/162).

Conclusions

Canaloplasty performed via an ab-interno technique resulted in a decrease of IOP in uncontrolled glaucoma eyes. The majority of baseline uncontrolled glaucoma eyes were IOP controlled following the canaloplasty procedure.
