The SNEC Ocular Reading Centre (SORC) provides evaluation and interpretation (grading) services of ocular pathology from fundus photographs, fluorescein angiograms, optical coherence tomography scans or other imaging modalities. SORC serves as a Tele-Ophthalmic Ocular Reading Centre, a hub that ensures effective and prompt service delivery by streamlining and automating the entire process, from image capture on site to the electronic transfer of the image via a dedicated conduit to the reading centre.

What We Do
Provide clinical trial standard reading services for industry partners and collaborators on different eye diseases such as diabetic retinopathy, age-related macular degeneration, glaucoma and cataract with strict quality assurance.

  1. Provide accurate measurement of vascular structure from retinal images using computer-aided programmes such as SIVA (Singapore “I” Vessel Assessment).
  2. Provide certification of equipment and photographers according to industry standards and maintain high quality imaging throughout the duration of trials.
  3. Perform centralized grading for the national diabetic screening programme in Singapore – Singapore Integrated Diabetic Retinopathy Programme (SiDRP)
  4. Conduct training workshops, mentoring sessions and accreditation for a spectrum of ocular imaging techniques.
  5. Our vast ocular imaging database and tele-ophthalmology platform are supported by a robust and well-equipped IT infrastructure.

Our Clients
We read and grade retinal images of 50,000 patients a year.  Our clients include the polyclinics, hospitals, screening centres, GP clinics and optical shops.

At SORC we also provide grading services for clinical trials by pharmaceutical companies and for research projects from overseas universities and institutions. We offer our grading service for the various grading techniques - DR (ETDRS & Simplified), AMD, SIVA and Fractals. 

The Diabetic Retinopathy Screening Programme at SORC

  • Traditional Diabetic Retinopathy Screening

Diabetic Retinopathy (DR) screening is the main method used to identify patients suffering from DR at an early stage. However, current DR screening models in many countries suffer from substantial limitations, including:

  1. Delay in diagnosis and referral of patients with DR
  2. Inconsistencies in the grading outcomes with no standardised protocol
  3. Evidence of high over-referral rate to tertiary eye care (i.e, substantial levels of false positive cases and ensuing high treatment costs at tertiary centres)
  4. Cost-ineffective as primary care doctors are made to assess DR when this can be performed by trained technicians
  5. Large proportion of patients with diabetes who visit private GPs and endocrinologists may be excluded.

Singapore Integrated Diabetic Retinopathy Programme (SiDRP) - National Diabetic Retinopathy Screening Programme in Singapore

Singapore Integrated Diabetic Retinopathy Programme (SiDRP) aims to improve on the traditional DR screening with the establishment of a comprehensive screening programme based on ‘real time’ assessment of DR from photographs by a centralised team of trained and accredited technicians, supported by a national tele-ophthalmology IT infrastructure. Patients’ retinal photographs are graded within an hour, allowing immediate feedback on DR status to be given during the same primary care visit together with, if necessary, and a referral to an ophthalmologist.

Majority of diabetic patients of all 18 polyclinics of the Singapore Health Services and National Healthcare Group are on the SiDRP.
