Researchers from NUS Computing, the Singapore National Eye Centre (SNEC) and the Singapore Eye Research Institute (SERI) have developed an artificial intelligence (AI) screening technology capable of identifying retinal images showing signs of diabetic retinopathy with high accuracy.
Diabetic retinopathy is a diabetes-related complication that affects one in three diabetic people. It is currently diagnosed using manual assessments of retinal photographs involving large teams of trained professionals.
The screening technology employs a deep learning system that uses representation-learning methods (in machine learning, representation learning is a set of techniques that allows a system to automatically discover the representations needed for feature detection or classification from raw data) to process large amounts of data, and recognise intricate structures and meaningful patterns that may not be visible to the human eye.
The researchers developed and trained the system to recognise and classify retinal images, and tested its performance against close to 500,000 images from multi-ethnic populations across the US, Australia, China, Hong Kong, Mexico and Singapore.According to the press release, this is by far the world’s largest dataset for evaluating the use of a deep learning system to screen for an eye condition.
(Researchers in different parts of the world have been trying to use AI for the diagnosis of diabetic retinopathy. In 2016, Google Brain collaborated with doctors both in India and the US, and created a development dataset of 128,000 images which were each evaluated by 3-7 ophthalmologists from a panel of 54 ophthalmologists. This dataset was used to train a deep neural network to detect referable diabetic retinopathy. In September 2017, researchers at the Commonwealth Scientific and Industrial Research Institute (CSIRO) announced the development of an AI-driven eye-screening technology for diabetic retinopathy.)
The same technology can also be employed to diagnose two other eye conditions – glaucoma suspect and age-related macular degeneration.
NUS Computing Professor Lee Mong Li Janice, who is part of the cross-institutional research team said, that the technology has sensitivity greater than 90 per cent and specificity greater than 85 per cent for the three eye conditions. (Sensitivity measures the proportion of positives that are correctly identified as such, while specificity refers to the proportion of negatives, that is people do not have the disease, who are correctly identified as such.)
There is a growing prevalence of diabetes in Singapore, with the disease affecting 400,000 Singapore residents, and one in three Singaporeans is at risk of developing it over his/her lifetime and the number of those with diabetes is projected to reach one million by 2050.
The researchers believe that their screening technology will provide a more efficient and sustainable way of screening patients for diabetic retinopathy.
Professor Wong Tien Yin, Medical Director of SNEC and Chairman of SERI, said that the technology will help increase efficiency and reduce cost. In countries with existing screening programmes, such as Singapore and the UK, it could replace a large proportion of the manual assessment required.
“In communities and countries without existing programmes and without sufficient ophthalmologists — such as developing countries, parts of China, India, South America — it can be used as a first line screening tool to accurately screen for cases that require referral to an ophthalmologist for treatment,” added Prof Wong, who is also Vice Dean (Clinical Sciences) at Duke-NUS Medical School.
The research team is now beta testing their AI screening technology in the Singapore Diabetic Retinopathy Screening Programme. They aim to increase their datasets to five million images from around the world over the next five years.
“We are also developing more complex algorithms for different severity levels of diabetic retinopathy, predictive algorithms for the incidence and progression of the eye condition and diabetes-related systematic complications such as stroke, coronary diseases and chronic kidney diseases,” added NUS Computing Professor Wynne Hsu.

This groundbreaking research endeavours to strengthen international collaborations, partnering with institutions such as the Singapore Nuclear Research and Safety Initiative (SNRSI) and the Singapore Synchrotron Light Source (SSLS).
The Ministry of Information and Communications (MIC) unveiled a draft decree earlier this year concerning the management, provision, and use of internet services, slated to replace the existing Decree 72. Under the proposed regulations, social networks will be required to remove content that violates the rules, with corresponding measures taken against offending accounts, community pages, and content channels. According to MIC, these heavy sanctions are expected to help clean up cyberspace.
The new draft decree includes more stringent requirements and more severe penalties for offenders. Organisations and individuals offering services, whether within Vietnam or internationally, are mandated to prevent and delete content that breaches the law immediately, once this is required by MIC. In cases where unreasonable content is not removed as instructed, MIC will employ technical measures to block websites, applications, and platforms that offer these services.
A notable addition in the draft decree compels social networks to temporarily or permanently suspend the accounts, community pages, community groups, and content channels that frequently breach regulations or engage in severe violations that impact national security. The regulations designed by MIC aim to address the sources of violations and reduce the time and resources expended by agencies in blocking and removing content in violation.
An industry expert has noted that that information is spreading rapidly across both domestic and international social networks. Failure to promptly address harmful information could lead to significant consequences for individuals and businesses. Moreover, inaccurate information concerning government policies circulating on social networks could severely undermine the reputation and functioning of state agencies.
The call for the immediate removal of violating content and the decision to suspend offending accounts can effectively resolve multiple issues simultaneously. In such a scenario, platforms will bear the responsibility of monitoring user posts, while users will need to be accountable for the content they generate.
It is essential to establish clear guidelines regarding the types of violations that need to be addressed and how much time platforms are allowed to do this. If the violations have relations with national security, they must be handled immediately. In this case, platforms must remove information in violation as soon as the watchdog agency sends links containing the violating information, with no need to send written requests. For other types of violations, it may be more practical to provide platforms with a reasonable amount of time to conduct thorough investigations into the cases before taking action.
With the ongoing digital transformation, the volume of sensitive data stored on digital platforms has surged, underscoring the importance of securing data as a critical priority. The National Cyber Security Centre (NCSC) has issued a warning regarding an increasingly serious scam involving the utilisation of deepfake technology to capture the movements and voices of unsuspecting victims for fraudulent purposes. This manipulation has resulted in financial losses for numerous individuals. It is anticipated that this artificial intelligence (AI)-based deception will evolve further in the future, becoming even more sophisticated and deceptive.
Personal data serves as the foundational building blocks for government and business databases. As a result, these data are regarded as invaluable resources for organisations and individuals to gather and use. The legitimate and lawful use of this data yields significant value. However, illegal activities that compromise personal data, leading to infringements on national security, social order, and security, can have severe consequences.
The University of Sydney has acquired an advanced 360-degree rotating cockpit simulator, enabling students and researchers to replicate the experience of piloting various aircraft, including A380s and spacecraft. Located within the School of Aerospace, Mechanical, and Mechatronic Engineering, this New Zealand-manufactured simulator, called the Eight360 NOVA Simulator, is the sole one of its kind in Australian universities.
This cutting-edge simulator uses virtual reality technology, providing students and researchers with a comprehensive understanding of how theoretical concepts and design choices impact aircraft behaviour. It enhances the learning and research process by providing a hands-on experience and immersing students in flight operations environments.
What sets this simulator apart from traditional flight simulators is its unlimited rotational axes, allowing for complex manoeuvres like spins and inverted flight. This capability empowers researchers to gain insights into how both aircraft and humans perform in challenging conditions, as well as to test and pilot vehicles they’ve designed.
The simulator operates “untethered” thanks to a freely movable ball resting on rollers that are powered by electric motors, enabling precise control over the ball’s positioning at varying speeds. As pilots manipulate the controls, the ball adjusts its position to mimic the orientation and acceleration of a real-flight vehicle.
Associate Professor Nicholas Lawson, who heads the Aircraft Performance and Operations department and joined the university in 2021, emphasized the importance of the simulator in bridging the gap between theoretical study and practical experience in aerospace and aeronautics.
One of the benefits highlighted by a Bachelor of Aerospace Engineering student is the simulator’s immersive experience, significantly enhancing her understanding of aerospace and space engineering. The student, who is also representing the university at an international space conference, praised the simulator as an excellent hands-on complement to theoretical learning.
Furthermore, the simulator holds potential for simulating space environments, including the control of crewed vehicles on planetary surfaces, a development area led by Visiting Professor Gregory Chamitoff, a former NASA Astronaut.
The acquisition of the advanced 360-degree rotating cockpit simulator by the University of Sydney reflects the Australian government’s interests in promoting STEM education, fostering innovation, and developing the aerospace industry. This cutting-edge technology not only attracts students to STEM disciplines but also contributes to the growth of the country’s aerospace sector.
Additionally, the simulator’s potential for international collaboration in space-related research and its capacity to develop a highly skilled workforce aligns with the government’s goals for innovation, technology transfer, and workforce development. While primarily an academic asset, this initiative indirectly supports broader national objectives in education, industry, and international engagement.
