AI-Integrated retinal-imaging device from India shows promising results in screening for Diabetic Retinopathy

Bengaluru (Karnataka) [India] Sept 12(ANI/BusinessWire India): Diabetic Retinopathy (DR), is asymptomatic and affects nearly 20per cent of the 70 million diabetic patients in India.

Timely and accessible DR screening can enable early detection, preventing needless blindness. Nearly 70per cent of the population, especially those in rural areas lack access to specialists, given the very low specialist to population ratio of 1:100000 in some areas. A landmark study published in the August issue of JAMA Ophthalmology (Journal of the American Medical Association), reports the feasibility of using a smartphone-based retinal camera with the world’s first, in-built automated, offline Artificial Intelligence (AI) algorithm, the MEDIOS-AI, designed by Bangalore-based Remidio Innovative Solutions, to implement sensitive and scalable screening models for DR.

A team from Aditya Jyot Foundation for Twinkling Little Eyes, Mumbai, led by Dr Natarajan, President of the All India Ophthalmology Society, has till date screened more than 1300 patients with diabetes mellitus in civic dispensaries in Mumbai for DR and validated the diagnostic accuracy of MEDIOS-AI to detect Referable DR, a condition requiring immediate specialist consult. The AI instantly provides a report in less than 10 seconds, on the smartphone.

Florian Savoy (VP, Data Sciences and AI) and Bhargav Sosale (VP, Software Design), the architects of Remidio’s smartphone-based AI solution, suggest that the novel, offline AI platform is ‘extendable to Glaucoma, AMD and other sight-threatening chronic diseases’.

The images were captured on Remidio’s smartphone-based, non-mydriatic, portable camera, the NM-FOP 10 and subjected to automated analysis by MEDIOS-AI, with simultaneous grading by vitreoretinal specialists. MEDIOS-AI relied on 2 convolutional neural networks, based on the MobileNet architecture – one assessing the image quality, and the other separating healthy images from images with referable DR (RDR). The clinical sensitivity and specificity of the MEDIOS-AI algorithm were found to be 100per cent and 88.4per cent for RDR, 85.2per cent and 92.0per cent for any DR respectively, exceeding US FDA’s superiority endpoints of an RDR sensitivity of 85per cent and specificity of 82.5per cent.

Dr TY Alvin Liu, MD, Assistant Professor of Ophthalmology at Johns Hopkins Bloomberg School of Public Health, in an invited commentary, calls the study ‘paradigm-shifting’.

“The study paves the way in implementing large scale models for screening for DR, even in locations with no internet infrastructure. This is a step ahead of the approach taken by Google and other AI companies that need their AI models to run on external servers, necessitating internet access,” said Dr Natarajan, MD.

“Technologies like Remidio NMFOP and Medios Offline AI, are necessary to move screening closer to the nearly 400 million patients at risk of blindness globally, due to chronic, asymptomatic conditions like Diabetic Retinopathy,” said Dr Anand Sivaraman, CEO, Remidio.

Indian astronaut Group Captain Shubhanshu Shukla, the first Indian to visit the International Space Station (ISS), will meet Prime Minister Narendra Modi this evening at his official residence in New Delhi.

PM Modi to host meeting with astronaut

According to officials, the meeting at 7 Lok Kalyan Marg is expected to take place between 5 pm and 5:30 pm. Shukla, who arrived in India on Sunday, will also be part of the National Space Day celebrations scheduled for August 23.

Warm welcome in India

The astronaut was greeted at the airport by his family, Science and Technology Minister Jitendra Singh, Delhi Chief Minister Rekha Gupta, and hundreds of citizens waving the national flag. Shukla had been in the United States for a year, preparing for the Axiom-4 mission, which launched from Florida on June 25 and docked at the ISS the next day. He served as the mission’s pilot.

Emotional note from Shukla

Before his return, Shukla shared an emotional post on Instagram, expressing mixed feelings of leaving his space colleagues while being eager to meet his loved ones and people of India. He also quoted a song from the film Swades, which he had chosen as his anthem on the launch day.

Parliament session on India’s space journey

In honour of Shukla’s mission, the Lok Sabha is holding a special session today to discuss “India’s first astronaut aboard the ISS – critical role of space programme for Viksit Bharat by 2047.” Union minister Kiren Rijiju said the discussion would highlight the importance of India’s space achievements and future goals.

Indian astronaut Group Captain Shubhanshu Shukla has shared an emotional Instagram post as he heads back home after completing his 18-day mission aboard the International Space Station (ISS).

Astronaut reflects on mixed emotions

In his heartfelt message, written from the aircraft, Shukla expressed the whirlwind of emotions he felt while leaving behind his fellow astronauts, who had been his family during the mission. “As I sit on the plane to come back to India, I have a mix of emotions running through my heart. I feel sad leaving a fantastic group of people behind who were my friends and family for the past year during this mission. I am also excited about meeting all my friends, family and everyone in the country for the first time post mission. I guess this is what life is — everything all at once,” he wrote.

Acknowledges support and inspiration

The astronaut thanked everyone for the love and support he received throughout his journey. He also recalled the words of his commander Peggy Whitson, saying, “Goodbyes are hard, but we need to keep moving in life. As my commander Peggy Whitson fondly says, ‘The only constant in spaceflight is change’. I believe that applies to life as well.”

Shukla ended his note with a line from the song Yun Hi Chala Chal from the film Swades, reflecting his spirit of resilience.

Link to India’s space ambitions

Shukla’s return comes at a crucial time as India advances its space programme. Prime Minister Narendra Modi had earlier mentioned that the astronaut would soon return and that he was tasked with documenting his training and ISS stay. This record will serve as a valuable reference for Gaganyaan, India’s first human spaceflight mission.

Over the past year, Shukla trained extensively at NASA, Axiom, and SpaceX facilities. His flight to the ISS as part of the Axiom 4 mission marked a milestone in India’s preparations for future human space exploration.

The Gaganyaan project aims to send Indian astronauts into orbit aboard an indigenous rocket. The government has also outlined plans for a Bharatiya Antariksh Station by 2035 and a crewed mission to the moon by 2040.
