Powerful image-computing platform for increasing access to eye-care

Need Preventive eye care for all

More than 50 million people in India are at risk of developing sight threatening eye diseases, such as glaucoma and diabetic retinopathy. Blindness due to these lifestyle related diseases is preventable, if detected early through regular eye check-up. But, with an ophthalmologist per population ratio of around 1:100,000 there is an acute shortfall of expert capacity in the country.

There is a need for large scale screening to tackle the dual challenge of huge population and limited availability of experts.

Innovation Computer assisted screening

HTIC has developed Eye-PAC™, a computing technology for extracting clinically relevant information from eye images. Eye-PAC™ technology consists of image computing and analytics built upon advanced mathematical and computational techniques. The processing, computing, and analytics modules of Eye-PAC™ can be used to develop a range of applications such as disease screening systems, computational platforms for ophthalmic devices, and tools for clinical research and analytics.

Impact Technology deployed in 10 countries

HTIC partnered with Forus Health, a young Indian med-tech company, to develop image computing solution based on Eye-PAC™ technology for their i n digenous multifunctional ophthalmic prescreening device, 3nethra. The computational intelligence capabilities of Eye-PAC™ have helped 3nethra reach more than 150 locations in 10 different countries. Eye-PAC™ technology empowers healthcare professionals such as technicians and optometrists to perform eye screening at places where a qualified ophthalmologist might not be available. Through customised solutions like 3nethra, Eye-PAC™ platform technology will continue to reach hundreds of thousands of eyes every year

Verification & Validation

Detection of Advanced DR signs

HTIC’s Diametry technology underwent initial clinical pilot study at Center for Sight Hyderabad from March 2014, where the system was deployed and the software was evaluated vis-à-vis expert readings in a clinical setting. The need for recognizing advanced/late stage DR signs was identified as a critical component for increasing screening reliability of Diametry in Indian scenario.

Analysis of advanced/proliferative DR is not well researched in literature. HTIC developed a novel method which hybridizes top-down and bottom-up strategies for localizing patches of image indicating proliferative DR signs, specifically neovascularization elsewhere (NVE). Evaluated on our large dataset, this research work was published in EMBC 2015, and further has been modularized and integrated into Diametry system.

Collaboration with Forus to develop AMD analytics

Continuing the collaboration with Forus Health, HTIC developed a system for screening of age-related macular degeneration (AMD), a leading cause of preventable blindness among elderly population. The system identifies disease signs associated with various stages of AMD, and also includes novel analysis of image-level disease screening and grading according to international standards.
The system developed has been evaluated not only on images from Forus’ 3nethra non-mydriatic camera, but also on challenging publicly available datasets.
