NA-AION Risk Factors: New Perspectives

United States, Australia, Canada179 participantsStarted 2021-08-01

Plain-language summary

The purpose of the study is to use new diagnostic methods (OCT and OCT-A) to shed light on risk factors for the development of NA-AION. The risk factors we are focusing on are comorbidities along with anatomical and vascular characteristics of the optic nerve.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion criteria

. Diagnosis of first episode of NA-AION in study eye with symptom onset within 1 month prior
. Subject age: Age \>10
. NA-AION diagnosis requires:

Exclusion criteria

. Previous episode of NA-AION in the study eye only
. Intraocular pressure of \>21 mm Hg in the study eye
. Clinical or pathological evidence of giant cell arteritis
. Diseases that may affect the optic nerve: glaucoma, multiple sclerosis, Alzheimer disease, and Parkinson disease. Evidence of optic disc drusen and optic nerve hypoplasia are not exclusion criteria given they are important parts of the study. We will not exclude significant retinal diseases, since they may be related to underlying etiologies giving rise to ODD, such as macular degeneration, retinal dystrophies, but eyes with significant retinal diseases will be analyzed separately.

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.
