Abstract Details

Purpose:

In the MIGS era, management of glaucoma is experiencing a shift toward surgery in an earlier anatomical and functional damage stage. The OMNI surgical technique is defined as a 360-degree viscodilation of Schlemm’s canal, followed by 360-degree trabeculotomy. This procedure aims to improve the aqueous humor drainage through it’s physiological outflow pathway. Our aim was to provide an initial evaluation of the OMNI procedure in a prospective study of 12 eyes with open angle glaucoma.

Setting:

Universitary and Polytechnic La Fe Hospital

Methods:

A prospective study was conducted on 12 eyes with primary open angle glaucoma. In 8 eyes the OMNI procedure was combined with cataract surgery. Intraocular pressure changes, number of medications and complications were recorded. Anterior Segment Optic Coherence Tomography (AS-OCT) images of angle and particularly trabecular morphology were performed at 6 weeks. Success was defined as intraocular pressure (IOP) lowered at least 20% from a baseline over six months. Follow-up is in progress, with intervals up to 6 months expected by September 2018.

Results:

Mean pre-operative IOP was 24,33mmHg(+-4,72mmHg) and the mean number of preoperative antiglaucoma drugs used by patients was 2,58(+-0.819). During the early postoperative period (6 weeks) the mean IOP decrease was 6,91mmHg with no additional antiglaucoma medication for 75% of patients. The mean number of post-operative medications were reduced to 0.5(+-0.71). AS-OCT at the supero nasal quadrant at 6 weeks revealed an identifiable trabeculotomy that measured 0,236micronsx0,315micronsx0,2 microns (height, depth and aperture to the anterior chamber). Main postoperative complications were transient. There was one case of toxic anterior segment syndrome (TASS) and one case of hyphema

Conclusions:

Early follow-up data in progress with the Omni surgical procedure is showing a reduction of IOP, with medication reduction, in treatment of moderate glaucoma in adults. The upcoming incremental follow-ups will offer further insight.
