The outcome of transscleral cyclophotocoagulation for the management of acute angle closure

Abstract

Purpose

To investigate the outcome of transscleral cyclophotocoagulation (TCP) in the treatment of acute angle closure (AAC) refractory to medical treatment.

Methods

This is a retrospective interventional case series. The inclusion criteria include patients diagnosed with AAC who had TCP. Pre-TCP and post-TCP intraocular pressure (IOP), visual acuity, and AAC treatment were analyzed. The complications and the results of subsequent treatments including lens extraction if performed were also assessed.

Results

Thirteen eyes (13 patients) met the study criteria. The median time to TCP from presentation was 5 days (range 3-30 days). The mean presenting IOP was 56 ± 6 mm Hg (range 48-70 mm Hg) and the medically treated mean IOP before TCP was 40 ± 5 mm Hg (range 34-52 mm Hg). All patients (100%) responded to TCP. The mean post-TCP IOP at day 1 and months 1, 3, 6, 12, and 24 were 19, 23, 19, 19, 18, and 17 mm Hg. There was 1 case of hyphema post-TCP. Lens extraction ± goniosynechialysis was performed in 10 patients (77%) from 1 month post-TCP onwards. The mean IOP prior to lens extraction was 26 mm Hg (range 19-32 mm Hg). The mean IOP 3 months after lens extraction was 15 mm Hg (range 8-19 mm Hg). The mean number of topical IOP-lowering medications 12 months post-TCP was 1.1.

Conclusions

Transscleral cyclophotocoagulation is effective and safe in reducing IOP in patients with AAC refractory to medical and laser peripheral iridotomy treatments. We advocate that TCP should be considered early in the management of AAC refractory to medical treatment to avoid irreversible optic neuropathy.
