Abstract

Purpose: To investigate intraocular pressure (IOP) lowering effect of modified 360-degree suture trabeculotomy (S-LOT).

Methods: All eyes for which we intended to operate S-LOT at Keio university hospital from February 2010 through January 2012 were included to the present retrospective study. Main outcome measures were rate of threading through 360-dgree of Schlemm canal, IOP, medications and complications. The ends of 5-0 nylon suture were rounded like a matchstick head by cautery. In cases unable to thread through 360-degree, we cut as much trabecular meshwork as possible by the same 5-0 nylon suture.

Results: Thirty six glaucomatous eyes of 33 patients were included to the study. All eyes were followed at least 6 months. Mean age was 59.4+/- 19.6, and 9 eyes were of female. 360-degree threading was possible in 26 eyes (72.2%). The mean IOP dropped from 33.2 +/- 9.0mmHg preoperatively to 16.5 +/- 5.9mmHg at one month (p<0.01), 14.4+/- 4.2mmHg at 6 months (p<0.01) and 13.3+/- 5.1mmHg at 12 months (p<0.01). Medications were 3.9 +/- 1.3 preoperatively, 0.66 +/- 1.2 at one month, 0.45 +/- 0.9 at 6 months and 0.46 +/- 1.0 at 12 months. There was no severe complication.

Conclusions: Modified 360-degree suture trabeculotomy was safe and effective surgery.
