Two SONDA Research Projects Co-Funded by the European Union
With support from the EU Just Transition Fund, Reyedar is developing new applications of SONDA with research partners: accessible screening for neuro-visual disorders in primary care, and eye-movement biomarkers for children with dystonia.

Reyedar is developing a range of applications for SONDA in collaboration with research partners, with support from the European Union’s Just Transition Fund. Two projects are under way in the Northern Netherlands, with the University Medical Center Groningen and Royal Dutch Visio.
Eye Tracking and AI for Cost-Effective Screening and Rehabilitation of Eye and Brain Diseases
Project JTFN-00091, July 2024 to June 2027, with the University Medical Center Groningen (UMCG) and Royal Dutch Visio. Total budget EUR 1,780,000, of which EUR 800,000 is granted.
The objective is to develop and implement SONDA, an automated and objective testing method based on eye-movement analysis using eye-tracking technology and AI, to enable accessible screening for neuro-visual disorders such as glaucoma in primary care: general practitioners, opticians and optometrists. We expect this to prevent unnecessary referrals to secondary care, to make better use of scarce healthcare capacity in the Northern Netherlands, and to establish a sustainable blueprint for regional and national neuro-visual care.


It’s in the Eyes: The Search for Biomarkers in Eye Movements in Children with Dystonia
Project JTFN-00174, January 2026 to December 2028, with the University Medical Center Groningen (UMCG). Total budget EUR 1,600,000, of which EUR 575,500 is granted.
To improve care for children with dystonia, we are developing an innovative and user-friendly tool for quantifying eye movements in children with the condition. We hope this will improve diagnosis, identify patterns that may lead to a better understanding of the underlying processes, and lead to a biomarker for disease progression.

About the Fund
The Just Transition Fund supports regions whose economies are most affected by the transition to climate neutrality. In the Northern Netherlands it invests in innovation and skills, which is where these two projects sit: new diagnostic capability built and tested in the region, with the people and partners who work here. The method behind both projects is described on the Digital biomarker page.
