Abstract Details

Purpose:

To review two case studies where ab-interno canaloplasty was performed to lower intraocular pressure, reduce topical medications, as well as symptomatic ocular surface disease in patients who had previously undergone microtrabecular bypass surgery.

Setting:

Private group practice, Chicago, Illinois, US

Methods:

Four eyes in two patients with POAG had previously undergone MIGS with implantation of a single stent combined with cataract surgery. 16 to 30 months postoperatively, the 4 eyes required 2 to 3 topical glaucoma medications to maintain control of IOP. The patients also had symptomatic ocular surface disease that did not respond to preservative-free glaucoma medications or any other standard treatment regimen. Ab-interno canaloplasty was performed to lower IOP, along with the number of topical medications. Visual acuity, slit lamp findings, IOP and gonioscopic findings were noted preoperatively, and postoperatively to 1 year.

Results:

The mean IOP was 17.5 mm/Hg with 2 to 3 topical medications needed to maintain control. Patients also reported decreased vision and irritation and were found to have ≥ 2+ conjunctival injection, and ≥ 2+ corneal epitheliopathy. Following ABiC, mean IOP was 16.8 mm/Hg, with 1 eye requiring 1 topical glaucoma medication. Both patients reported improved vision and elimination of symptoms. Slit lamp findings showed ≤ 1+ injection and epitheliopathy.

Conclusions:

Ab-interno canaloplasty can be used effectively to reduce intraocular pressure, as well as the need for topical medications in ocular surface disease patients who have previously undergone microtrabecular bypass surgery.
