Plain-language summary
The prevalence of idiopathic epiretinal membranes (ERM) in people over 50 is estimated at 6 to 19%. Even though most cases show very few symptomats, they may induce alterations of the underlying retina and lead to visual impairment likely to greatly diminish quality of life in patients. Thanks to the ever-improving quality of vitreo-retinal surgery, ablation of these membranes is a frequent and safe procedure allowing a functional gain in the majority of cases. Given the increasing prevalence in the population concerned and the accelerated ageing of the lens after vitrectomy, cataract surgery is often associated with removal of the membrane. On the basis of a study in 142 patients, it was possible to identify clinical and morphological prognostic factors and to inclure them in a score to assess the chances of complete functional recovery at one year following the procedure . Age of the patient, the duration of symptoms, initial visual acuity and the quality of the junction between external and internal segments of photoreceptors in optic coherence tomography (OCT) appeared as significantly related to visual results. Using this score in a new prospective cohort would allow the investigators to make it a reliable and easy-to-use tool at the service of ophthalmologist surgeons and their patients and would provide scientific confirmation of the interest of earlier surgery in this disease. It would also allow the investigators to define in a validated and reproducible manner, a threshold for an ndication for ERM surgery, which is currently based on relatively subjective criteria mostly related to visual acuity.

* Patient présentant toute autre maculopathie ou neuropathie optique ;
* Patient presenting severe myopia (spherical equivalent ≥ 6 diopters or axial length ≥ 26 mm) ;
* Patients presenting any other ophthalmological disease independent of the ERM and likely to limit visual acuity
* Patients who have already undergone vitrectomy in the studied eye;
* Non-visible or poorly visible fundus due to a cloudy vitreous (Signal on OCT Cirrus \<5, Quality score on OCT Spectralis \< 20, signal trend index on OCT Optovue \< 30)

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?
