This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study used a special camera to measure how long natural fluorescent substances in the retina stay lit up after being excited by light. The goal was to see if these measurements can reveal areas of the retina under stress, like from poor blood flow. Nearly 900 healthy volunteers and patients took part, with some having up to four measurements over two years. The research aims to improve understanding of retinal health and disease detection.
