New eye camera could spot hidden signs of blindness
NCT ID NCT07530783
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new, non-invasive eye imaging method called hyperspectral imaging. It takes pictures of the back of the eye using many different colors of light to find details not visible with standard cameras. About 679 adults with healthy eyes or eye diseases like diabetic retinopathy, glaucoma, and age-related macular degeneration took part. The goal was to see if this technique can detect unique light patterns linked to disease and help doctors diagnose eye problems earlier.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 years and older * Able to provide informed consent * Willing and able to attend study imaging sessions * Participants with healthy eyes or diagnosed retinal/optic nerve disease (including but not limited to diabetic retinopathy, glaucoma, and age-related macular degeneration) * Adequate media clarity to permit retinal imaging as determined by investigator Exclusion Criteria: * Inability to provide informed consent * Known history of narrow anterior chamber angles or risk of acute angle closure where pupil dilation is contraindicated * Ocular media opacities preventing adequate retinal imaging (e.g., dense cataract, severe corneal opacity, vitreous hemorrhage) * Any condition that, in the opinion of the investigator, would make participation unsafe or compromise study data quality * Allergy or contraindication to pharmacologic mydriatic agents used for pupil dilation
