Can a phone app ease the emotional toll of glaucoma?
NCT ID NCT06053307
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a mobile app that teaches Acceptance and Commitment Therapy (ACT) to help people with glaucoma cope with anxiety, depression, and emotional distress. Researchers worked with 28 patients to see if the app was acceptable and easy to use. The goal was to lay the groundwork for a larger future study on whether this approach can improve emotional well-being and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Acceptance and Commitment Therapy (ACT) delivered via a mobile app
- What this could lead to
- If it works, this could offer a practical way to help glaucoma patients cope with emotional distress and improve their quality of life.
- What could go wrong
- This is a very small pilot study with only 28 participants and no control group, so results may not apply broadly. The intervention is behavioral and may not work for everyone.
