Using retinal health to assess brain blood vessel conditions

Official title: Retinal Vasoreactivity is a Marker for Cerebral Small Vessel Disease Progression

Run by Mayo Clinic · NCT04753970 · Data updated 2026-11-12

This study is testing if changes in the eye can help track brain blood vessel problems and whether a medication called cilostazol can slow down these issues in people with certain types of brain diseases.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older diagnosed with CADASIL, sporadic white matter disease, or lobar cerebral microbleeding.

Probably not a fit

Patients under 18, pregnant or breastfeeding women, and those unable to tolerate MRI or follow commands may not benefit from this study.

What this trial studies

This study investigates whether retinal vasoreactivity can serve as a biomarker for the progression of cerebral small vessel disease (SVD) and evaluates the safety and efficacy of cilostazol, an antiplatelet agent, in slowing SVD progression. Participants will include individuals diagnosed with CADASIL, sporadic white matter disease, and lobar cerebral microbleeding, along with age-matched healthy controls. The study will involve retinal scans, brain imaging, cognitive assessments, and blood samples at baseline and after 12 months. Patients with sporadic white matter disease will be randomized to receive cilostazol or no treatment, with follow-up assessments to monitor disease progression and cognitive changes.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for slowing the progression of cerebral small vessel disease.

How similar studies have gone: While the approach of using retinal biomarkers for cerebrovascular health is promising, it remains largely novel and untested in this specific context.
