Topcon Healthcare will acquire Toku, Inc. and announces investment from Sanro Health

Topcon Healthcare will acquire Toku, Inc., according to a press release issued by the company. Topcon Healthcare has global headquarters in Tokyo, Japan and a health innovation centre in La Jolla, California. Toku, also based in California, is a healthcare artificial intelligence (AI) company that uses color fundus photographs to deliver assessments of health. The press release notes that Toku’s planforms “are powered by one of the world’s largest retinal-image datasets.”¹ Toku reports that, as of the press release, the company has analysed over 4.3 million de-identified retinal images linked to clinical data.¹

The acquisition and integration of these platforms into Topcon’s current suite of offerings have the potential to leverage “oculomics to empower both primary care and eyecare providers with predictive, preventive health insights.”¹

The financial aspects of the deal were not disclosed in the press release.

In the week following the announcement of this acquisition, Sanro Health, Inc. is reported to have made an investment in Topcon Healthcare. According to the joint release issued by Sanro Health (based in Australia) and Topcon, the goal of this investment is to allow the two companies to work together to align ophthalmic data to be useable and actionable.²

Notably, the Sanro Optimizer is a programme that “integrates electronic health record and imaging data to create intelligent patient profiles and ranked cohorts, identifying eligible participants for clinical trials in real time during routine patient care across eyecare providers. This capability establishes a foundation for real-world AI, leveraging Sanro’s proprietary AI and interoperability framework to enable personalised research and care.”²

Together the acquisition of Toku and the investment from Sanro Health points to the continued efforts of Topcon Healthcare to advance its “Healthcare for the Eye” strategy. This strategy has been described by the company as, “a connected care ecosystem that leverages AI-powered disease detection and management applied to noninvasive retinal imaging.”

As AI tools and platforms continue to evolve in healthcare, and specifically within the ophthalmology field, Ophthalmology Times Europe is committed to covering the latest advancements to empower providers to stay up to date and aware of the changing landscape.
