New study tracks silent eye changes that could lead to vision loss
NCT ID NCT07236671
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 250 adults aged 45 and older who have pachychoroid, a condition where the choroid layer in the eye is abnormally thick. Researchers will track changes in the eye's veins over time to see how the condition develops and what factors might make it worse. The goal is to better understand who is at risk for vision problems and why.
