Abstract

Background: The aim of this study was to assess the effect of goniosynechialysis on intraocular pressure and medication requirement in patients with angle closure.

Design: A retrospective chart review.

Participants: 51 eyes from 42 patients were included in the study. 17 had documented evidence of acute angle closure while 34 had chronic angle closure.

Methods: Examination of the medical records of patients with synechial primary angle closure who underwent combined phacoemulsification and goniosynechialysis from 2003-2011 at 3 centres.

Main outcome measures: Intraocular pressure and requirement for drops were the main outcome measures.

Results: Mean follow-up was 25.9 months for the acute group and 25.4 months for the chronic group. Mean preoperative intraocular pressure was 23.33 ± 14.41 mmHg on an average of 2.51 ± 1.3 medications. Mean postoperative intraocular pressure was lowered to 13.67 ± 2.41 (p ≤ 0.01) and medication usage was significantly lowered to 0.65 ± 0.87 (p ≤ 0.01). Subjects with documented acute symptomatic angle closure had higher preoperative intraocular pressure and a larger intraocular pressure fall post goniosynechialysis (from 30.41 mmHg ± 23 mmHg to 12.12 mmHg ± 2.32 mmHg) compared to those without such a documented episode (19.79 mmHg ± 4.37 mmHg to 14.44 mmHg ± 2.08 mmHg, p = 0.007). Both groups have similar postoperative need for glaucoma medication, 0.65 ± 0.93 vs 0.65 ± 0.85.

Conclusions: Combined phacoemulsififcation and goniosynechialysis reduces intraocular pressure, medication requirements and need for further surgery in subjects with angle closure. The procedure is more effective in eyes with a previously documented acute symptomatic presentation of angle closure.
