SERI researchers develop AI tools for screening kidney disease, predicting age using eye photos | NEWSRUX

Researchers from the Singapore Eye Analysis Institute have developed two novel AI-powered instruments for screening persistent kidney illness and predicting an individual’s organic age from retina pictures.

Each instruments use AI deep studying algorithms to scan pictures of a person’s retina to evaluate their well being situation.


The kidney illness screening instrument referred to as RetiKid was developed by SERI and the Nationwide College of Singapore’s College of Computing in 2019. The instrument was skilled with over 23,000 retinal photos from practically 12,000 contributors in Singapore and China. 

In a research, it was proven to have an accuracy of 91% in an inner take a look at and 73% and 83% accuracy in two exterior take a look at units. The screening instrument has been licensed to well being tech startup EyRIS for manufacturing and commercialisation. 

Each retina and kidneys share a “shut organic relationship,” in line with Charumathi Sabanayagam, deputy head of SERI’s Ocular Epidemiology Analysis Group. ”Thus, issues with blood vessels within the retina may present clues to modifications in kidney blood vessels”.

RetiKid could also be used as a preliminary screening take a look at for detecting CKD on the whole populations and high-risk teams, resembling these with diabetes. As soon as carried out, sufferers might be counselled to proceed with routine confirmatory blood and urine checks.

The opposite AI instrument, RetiAge, was later developed in 2021 by SERI and Medi Whale, a healthcare startup in South Korea. It was examined in additional than 129,000 retinal photos from over 40,000 South Korean people. The instrument was additionally evaluated for its capacity to foretell the 10-year threat of illness and dying amongst 56,000 individuals within the UK Biobank database. 

The blood vessels in an individual’s retina can also present their ageing course of and the general well being of their blood and mind, stated Cheng Ching-Yu, head of SERI’s Ocular Epidemiology Analysis Group and Knowledge Science Analysis Platform. “The retina is a non-invasive window into one’s organic age and systemic well being standing, and may inform us many issues about an individual’s morbidity and mortality dangers”.

An individual’s organic age, as in comparison with their chronological age, can higher seize the physiological modifications related to ageing. Subsequently, it may be used to evaluate their basic well being standing. Cheng additionally claims that organic age is of higher curiosity to researchers, particularly given the worldwide ageing inhabitants and rising incidences of persistent illnesses.


Each RetiKid and RetiAge supply a non-invasive strategy to screening well being circumstances in clinics. Sufferers might discover them extra bearable, presumably resulting in extra uptakes of and compliance with preliminary well being screening.

Each instruments can be built-in with the Singapore Eye Lesion Analyser Plus, a retinal image-based system developed by SERI, which is at the moment being utilized by polyclinics throughout Singapore to display screen for diabetic eye illnesses, glaucoma and age-related macular degeneration.

For RetiKid, the screening course of is automated, which permits for efficient mass screening of at-risk sufferers. “Instruments like RetiKid have [the] potential to be broadly utilized in major care to enhance the present fee of CKD screening,” stated Dr Cynthia Lim, a key investigator of the RetiKid challenge. 

Moreover, RetiKid has the potential to be related with smartphones, enabling point-of-care prognosis. “Well timed detection of CKD permits clinicians and sufferers the chance to intervene early and decelerate [its] development,” Dr Lim stated.

Presently in its validation section, RetiKid goes for use in a group outreach programme by SERI in partnership with the Nationwide Kidney Basis. The programme, which runs from February 2022 to January 2024, will contain about 1,200 contributors with a excessive threat of creating CKD.

In the meantime, researchers are at the moment engaged on refining the algorithms in RetiAge to optimise its prediction efficiency within the native inhabitants. They’re additionally trying if it can be used to foretell different age-related illnesses.


The Singapore Nationwide Eye Centre claims that the Singaporean inhabitants is “uniquely susceptible” to eye illnesses and issues at each life stage. Myopia or nearsightedness impacts one in two kids by age 12. Amongst working adults, diabetic retinopathy is a significant reason for imaginative and prescient loss. Furthermore, the danger of blindness will increase 15 instances for Singaporeans aged 50 and above. 

Amongst latest improvements in eye well being in Singapore is an AI-based glaucoma screening technique developed by a crew of scientists and clinicians from the Nanyang Technological College and the Tan Tock Seng Hospital.

To assist broaden the entry to eye care within the nation, Johnson & Johnson Imaginative and prescient has crafted a three-year roadmap to develop an built-in eye well being ecosystem, specializing in knowledge and digitisation initiatives. Some key initiatives it plans to implement embody a group eye well being e-referral community, an AI-powered eye care service, and telehealth.
