Glaucoma screening study halted after only 26 participants
NCT ID NCT06135727
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study aimed to collect eye scan data from people with and without glaucoma to develop a new screening tool called the Topcon Health Score. The researchers planned to use a special camera to measure the thickness of nerve layers in the eye. However, the study was terminated early after enrolling only 26 participants, so its goals were not fully achieved.
