Abstract Details

Purpose:

To assess if 180 degrees of ABiC can sufficiently reduce IOP and the number of medications in patients with open angle glaucoma (OAG).

Setting:

Surgeries performed at a hospital surgical suite. Post operative visits and analysis performed in an office setting.

Methods:

Retrospective case series of 8 patients who underwent ABiC with treatment of 180-degrees of the canal and distal channels. No other minimally invasive glaucoma procedures were performed during the follow-up period, though 4 patients had previously undergone selective laser trabeculoplasty (SLT).

Results:

Eight patients with a mean follow-up of 6 months. The mean pre-op BCVA was 20/40, a mean IOP of 23.6 mm Hg and an average number of 3.2 medications.  Postoperatively, mean IOP was 15.3 mm Hg, a 35% reduction and the mean number of medications dropped to 1.3. Of the 2 patients with a lower pre-op IOP (13.4 mm Hg),meds dropped from 3.5 to 0.5. IOP post op was 14.2 mm Hg. Of the 3 patients with high IOP (31.3 mm Hg), pre-op meds 3.8 were reduced to 1.5 with IOP down to 18.3 mm Hg. No complications were noted.

Conclusions:

No difference in efficacy was seen between 180 degrees dilation of the inferior versus the superior half. Further, 180-degree ABiC appears to be a safe and effective treatment option in patients with mild to moderate OAG, reducing IOP, as well as the number of medications needed to control their IOP
