CLINICAL SERVICES - RETINA CENTRE
INTRODUCTION : WHO WE ARE
The Retina Centre looks after the medical retina and surgical retina services at SNEC ophthalmology services in Balestier, Changi General Hospital and KK Women's and Children's Hospital in addition to the SNEC main centre and the Diabetes and Metabolism Centre. It is also responsible for developing allied health services including ophthalmic imaging service, visual electrodiagnostic service, low vision service and the Singapore Integrated Diabetic Retinopathy Programme.
The steady stream of clinical research conducted at SNEC over the years has been tremendously boosted by Professor Wong Tien Yin, SNEC Medical Director, who has dedicated time and resources to those keen to pursue retinal research.
The Retina Centre is committed to research efforts that will improve patient care and advance translational vision science research in retina, vitreous and macular diseases. It also provides quality undergraduate and residency teaching, as well as subspecialty fellowships. Among other research projects, the team of ophthalmologists in Retina Centre is participating in multi-centre clinical trials of new therapies, and is tracking patients with retinal diseases in Singapore.

The Medical Retina Department plays a critical role in managing a broad spectrum of conditions, from heredofamilial conditions and age-related retina degenerations, to myopic macular disorders and metabolic-related conditions.
Our clinical team of retinal specialists, supported by a team of specialised allied health professionals and nurses including clinical trial coordinators, nurse counsellors as well as ophthalmic imaging professionals, work closely to deliver a range of therapies to treat retinal conditions.
Our treatment capabilities include full suite laser facilities such as high speed multi-spot pascal lasers and photodynamic therapy with visudyne, and intravitreal anti-VEGF injections. Anti-VEGF therapy is currently the most commonly used therapy. Since it became available in Singapore in 2008, our Centre has increased our capacity to provide this sight-saving therapy to our patients. The number of injections performed each year has increased from 1,000 in 2009 to almost 6,500 in 2014.
The electrophysiology unit provides diagnostic tests such as electroretinagraphy (ERG), multifocal ERG, electrooculography (EOG) and visual evoked potential (VEP) which are integral components in managing patients with retinal disorders and neuro-ophthalmological conditions with unexplained visual loss.
The Department strives to provide the most up-to-date, evidence-based treatment for our patients. This is supported by our constant efforts in conducting clinical research. A key area of research is the study of Asian-specific features of age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV).
Our department, in conjunction with the Singapore Eye Research Institute (SERI), has conducted many epidemiological and clinical studies, which have been important in guiding best clinical management. Besides benefiting our patients, our research has propelled SNEC to become an international leader in ophthalmology.
Diagnosis and management of
• Heredofamilial retinal conditions
• Retinovascular eye diseases
• Myopic macular disorders
• Diabetic retinopathy and maculopathy
• Age-related macular degeneration (dry and wet)
• Polypoidal choroidal vasculopathy
• Miscellaneous eye conditions, e.g. central serous retinopathy and floaters
• Ophthalmic imaging
• Low vision
• Intravitreal anti-VEGF injections
• Laser photocoagulation (including photodynamic therapy with visudyne)
• Disease counselling
The retina is the critical nerve tissue in the eye that receives all light signals entering the eye. Severe retinal disease, although infrequent, therefore tends to cause blindness. In SNEC, approximately 1,200 vitreo-retinal surgeries are performed annually for visually important retinal conditions.
Among these important conditions, retinal detachment is the most common blinding condition requiring surgery. The treatment techniques include pneumatic retinopexy, scleral buckle and pars plana vitrectomy.
Diabetes mellitus, currently affecting about 12% of Singaporeans, is increasingly common in many advanced and advancing societies, and diabetic eye disease is the most common complication. Advanced diabetic eye diseases including vitreous haemorrhage, complex tractional retinal detachment and fibro-proliferature diabetic retinopathy are managed by our team of vitreo-retinal surgeons using state-of-the-art vitreo-retinal equipment and techniques including bimanual surgery.
The Surgical Retina Department also manages other complex retinal conditions including proliferative vitreoretinopathy, giant retinal tears, myopic macular hole detachments, myopic macular schisis, endophthalmitis (intraocular infection) etc. The surgical tools include high-speed vitrectomy machines, intraoperative laser, microsurgical wide-field viewing equipment and various intra- and post-operative intraocular tamponade agents including heavy liquids, silicone oil and gases.
Other surgical vitreo-retinal capabilities include no-stitch 23 & 25 gauge vitrectomy macular surgery, peeling of epiretinal membranes and macular hole surgery. In ocular trauma, the Department manages complex posterior segment trauma including perforating eye surgeries with the use of temporary keratoprosthesis and operative endoscope for complex anterior and posterior segment injuries.
The high surgical success rate is due to the intensive training received by our team of highly experienced surgeons, many of whom have done extended fellowships. The team also trains aspiring retinal fellows from the region and further afield. To assure quality, all vitreo-retinal operations performed at SNEC are audited, and the success rates of retinal detachment surgeries are analysed every year. Our surgical results are comparable to, if not better than, those of international tertiary eye centres.
• Treat common conditions such as retinal tears, retinal detachments, macular puckers, macular holes, vitreomacular traction, diabetic vitreous haemorrhage, and less common conditions such as proliferative vitreoretinopathy, chronic retinal detachment, giant retinal tears, myopic macular schisis, trauma
• Perform surgical procedures such as intraocular injections, lasers, pneumoretinopexy, scleral buckling and pars plana vitrectomies
