Topcon Healthcare seeks to advance company through acquisition and new investment

Topcon Healthcare will acquire Toku, Inc, according to a news release issued by Topcon. Toku is a health care artificial intelligence (AI) company that uses color fundus photographs to deliver assessments of health. The release notes that Toku’s platforms “are powered by one of the world’s largest retinal-image data sets.”¹ Toku reports that, as of the news release, the company has analyzed over 4.3 million deidentified 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 eye care providers with predictive, preventive health insights.”¹ The financial aspects of this deal were not disclosed in the news 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 Topcon and Sanro Health, the goal of this investment is to allow the 2 companies to work together to align ophthalmic data to be usable and actionable.²

Notably, the Sanro Optimizer is a program 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 eye care providers. This capability establishes a foundation for real-world AI, leveraging Sanro’s proprietary AI and interoperability framework to enable personalized research and care.”²

Together, the acquisition of Toku and the investment from Sanro Health point to the continued efforts of Topcon Healthcare to advance its “health care for the eye” strategy. The company has described this strategy 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 the health care field, and specifically in ophthalmology, Ophthalmology Times is committed to covering the latest advancements to empower providers to stay up-to-date and aware of the changing landscape.
