Longitudinal Study of Retinal Function in Eyes Treated for Diabetic Macular Edema With Anti-VEGF Agents
100 participantsStarted 2026-05-01
Plain-language summary
A considerable hurdle to the development of novel, more effective therapies for diabetic retinal disease is the limited number of primary endpoints available for use in regulatory trials. Current endpoints necessitate long trial durations and a greater number of participants to show efficacy. Thus, a better understanding of the structural and functional changes in the retina occurring in people with diabetes is essential for developing primary endpoints and validating surrogate and clinical endpoints.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Key inclusion criteria:
* Age ≥18 years
* Diagnosed with Type 1 or Type 2 diabetes
* Best corrected visual acuity 20/320 or better (Snellen) (≥24 ETDRS letters)
* At least 1 eye with CI-DME requiring treatment
* Able and willing to provide informed consent.
Key exclusion criteria:
* Ocular or systemic condition, aside from diabetes mellitus (DM), that is likely to affect the assessment of DRSS, DME, or the functioning of the neural retina.
* Previous treatment of any kind for diabetic retinopathy or DME
* Any condition that may preclude adequate imaging of the macula (e.g. dense cataract or other media opacity, ptosis)
* History of rhegmatogenous retinal detachment or macular hole
* History of vitrectomy
* Intraocular surgery (including cataract surgery) within 4 months prior to enrollment or anticipated within the next 6 months
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
