As the local and regional referral centre for secondary and tertiary management of glaucoma, the SNEC Glaucoma Service manages over 40,000 glaucoma attendances annually - including over 2,000 attendances from the region. Our glaucoma consultants manage paediatric and adult glaucomas with more than 600 glaucoma surgeries performed every year.
Checking the eye (intraocular) pressure
Our Glaucoma Service manages the following glaucoma conditions:
- Paediatric and Childhood Glaucomas
- Open Angle Glaucomas including Normal Tension Glaucoma
- Angle Closure Glaucoma
- Secondary Glaucomas
Our Glaucoma Service also provides Glaucoma Patient Education and Counselling as well as Glaucoma Patient Support Group.

Our Glaucoma Service expertise includes:
• Glaucoma Diagnostics
Our Glaucoma imaging service utilises the following equipment for early detection and monitoring of glaucoma
▶ Stereoscopic Optic Disc Photography
|
A glaucomatous optic disc
|
Examination of the angle structures
|
▶ Anterior segment imaging technology Anterior Segment Optical Coherence Tomography,
(ASOCT); Ultrasound Biomicroscopy, (UBM)

▶ Optic nerve/nerve fibre layer imaging technology
- Heidelberg Retinal Tomography (HRT),
- Optical Coherence Tomography (OCT) and Spectral Domain Optical Coherence Tomography (SD-OCT)
- GDx Nerve Fiber Analyzer

• Glaucoma Therapeutics
Our Glaucoma Consultants use a comprehensive list of glaucoma medications:
▶ Beta-blockers
▶ Alpha-agonists
▶ Prostaglandin Analogues
▶ Carbonic Anhydrase Inhibitors
▶ Fixed combination drugs in the management of glaucoma
• Laser Glaucoma Management
We use various lasers in the management of glaucoma, including:
▶ Laser Peripheral Iridotomy
▶ Iridoplasty
▶ Argon laser trabeculoplasty (ALT)
▶ Selective laser trabeculoplasty (SLT)
▶ Trans-scleral cyclophotocoagulation (TCP)
We perform more than 1,000 glaucoma laser surgeries every year.
• Surgical Glaucoma Management
Our Glaucoma Consultants perform various glaucoma surgeries for paediatric and adult patients. The glaucoma surgeries performed at our centre include:
▶ Goniotomy
▶ Trabeculectomy
▶ Combined Trabeculectomy and Cataract surgery
▶ The use of Glaucoma Drainage Devices like the Ahmed valve and Baerveldt tube, as well as novel
devices like the Ex-press Shunt.
▶ Needling of blebs with anti-metabolites
Anti-metabolites are used routinely in our glaucoma surgeries

The Service also offers surgery for more complex and refractory glaucoma cases including those requiring reoperations and bleb revision.

We practise independent annual audit. It has calculated our surgical success rate at achieving an intraocular pressure of less than 21mmHg for primary glaucoma at one year. With trabeculectomy this is 97.3% to 99%. For combined cataract and trabeculectomy surgeries for primary glaucoma our success rate is 96.7% to 99.6%. The success rate for tube-shunt surgery for refractory and complex glaucoma cases is 89.3% to 93.3%.
