Secondary study design	Randomised controlled trial
Study type	Participant information sheet
Scientific title	Evaluation of efficacy and safety of viscogonioplasty in narrow angle glaucoma: a randomised single blind single centre controlled trial
Study objectives	Viscogonioplasty combined with cataract surgery in patients with narrow angle glaucoma will have a greater effect on intraocular pressure than cataract surgery alone.
Ethics approval(s)	Sunderland local research ethics committee (LREC) approved on the 21st February 2006 (ref: 05/Q0904/111)
Health condition(s) or problem(s) studied	Narrow angle glaucoma
Intervention	Cataract surgery combined with viscogonioplasty or cataract surgery alone. Follow-up of the patients intraocular pressure was for 12 months post-operation with a clinic visit at 3, 6 and 12 months.
Intervention type	Other
Primary outcome measure(s)	Intraocular pressure lowering following cataract surgery and viscogonioplasty versus catarct surgery alone, measured at 12 months
Key secondary outcome measure(s)	1. Opening of drainage angle when examined on gonioscopy, measured at 12 months 2. Complications following viscogonioplasty, measured immediately following surgery
