Streamline procedure with phacoemulsification significantly reduces IOP in OAG

Mean intraocular pressure (IOP) was significantly reduced in patients with mild to severe open angle glaucoma after incisional goniotomies and canaloplasty with the Streamline surgical system when combined with phacoemulsification, according to a study presented at the 2023 American Glaucoma Society Annual Meeting.

In this retrospective case series, 38 eyes from 26 patients with mild to severe open angle glaucoma who underwent the Streamline procedure at the time of phacoemulsification cataract surgery were analyzed. Most patients had primary open angle glaucoma (82%) and mild disease (68%). There was a baseline mean IOP of 16.1 mmHg and a mean baseline of 1.3 medications.

Surgical success was defined as an IOP reduction of ≥20% and/or the reduction of ≥1 topical glaucoma medication.

At 6 months after surgery, the surgical success rate was 66.7%. Baseline mean IOP decreased to 13.7 mmHg at 1 month postoperatively, to 13.7 mmHg at 3 months postoperatively, and to 15.4 mmHg at 6 months postoperatively (P < 0.001 for all).

Medication use also decreased at 1 month postoperatively and was sustained at 3 and 6 months postoperatively.

A single eye experienced an IOP spike, which was treated with topical medications. No other procedure-related complications were reported.
