What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests two advanced eye imaging techniques—central microperimetry and radial OCT—to see if they can more accurately measure the progression of geographic atrophy, a severe form of age-related macular degeneration that can lead to blindness. Researchers will follow 80 adults aged 55 and older who either have geographic atrophy or are at risk of developing it. The goal is to improve how doctors track the disease's advance toward the center of the retina, which is crucial for sharp vision.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Subjects must be 55+ years of age Subjects in the "Intermediate AMD Observation Arm" must have intermediate age-related macular degeneration in one eye Subjects in the "GA Observation Arm", "GA Continuing Treatment Arm", and "GA Treatment Arm" must have non-central GA (defined as GA has not involved the center point of the fovea) and at least 1% GA in the central 1 mm zone. Exclusion Criteria: * Subjects with central involvement of GA. Central involvement is defined as geographic atrophy involving the foveal center point. Subjects with a baseline size of GA \> 17.5mm2 (7.0 Macular Photocoagulation Study Disc Areas). Subjects who are: pregnant women, adults who cannot consent for themselves, and those who use alcohol in excess. Excess alcohol use is defined by binge drinking (pattern of drinking that brings blood alcohol concentration levels to 0.08 g/dL) on 5 or more days in the past month. Evidence of retinal atrophy due to causes other than atrophic AMD. Subjects who have had anti-VEGF injections or active choroidal neovascularization in the study eye during the last 12 months Current evidence or history of ocular disorders in the study eye that in the opinion of the investigator confounds study outcome measures, including (but not limited to): 1. Non-proliferative diabetic retinopathy involving 10 or more hemorrhages or microaneurysms, or active proliferative diabetic retinopathy 2. Branch or central retinal vein or artery occlusion 3. Macular hole 4. Pathologic myopia 5. Uveitis 6. Pseudovitelliform maculopathy 7. Intraoperative surgery within the last 90 days prior to study eye enrollment
