Spectacle Tints and Thin-Films for Migraine

Stopped: Too difficult to enroll according to inclusion/exclusion criteria

United States10 participantsStarted 2016-08

Plain-language summary

Nearly all migraine sufferers report sensitivity to light during a headache and a significant proportion of sufferers report light sensitivity between attacks. Light is also a common trigger for migraine headaches. Spectacle lenses that have been treated with tints and spectacle lenses that have been treated with thin-films have both been shown to reduce light sensitivity and headache in patients with migraine. At this time, it is not clear which spectacle lens treatment is superior. The purpose of this trial is to determine if there's a significant, therapeutic advantage to either spectacle lens treatment. Both treatments could be a novel, non-invasive adjuvant in the treatment of migraine.

Inclusion Criteria: * Subjects must meet the International Headache Society criteria for chronic migraine (International Classification of Headache Disorders, 3rd edition (Headache Classification Committee of the International Headache Society, 2013). All subjects must be between the ages of 18 and 60 years-old. To be included in the study, in the best judgment of the investigator, subjects must be stable on their current migraine treatment regimen. Stability is defined as no major changes in therapy contemplated within the next 4 months. Exclusion Criteria: * Subjects with other light sensitive conditions, such as iritis and blepharospasm, will be excluded. Subjects with best-corrected visual acuity less than 20/40 will be excluded. Subjects with diseases of the retina, such as diabetic retinopathy and macular degeneration will be excluded. Subjects using medications known to affect the eye will be excluded (e.g. chloroquine, hydroxychloroquine, ethambutol, amiodarone). Due to constraints on the manufacture and mounting of study lenses into study frames, the study must exclude subjects who are very nearsighted (more than 4 diopters), subjects who are very farsighted (more than 2 diopters), and subjects who have more than 2.5 diopters of astigmatism. Because of the cyclical effects of botulinum toxin injections and other nerve blocks, patients undergoing these treatments will be excluded. Subjects must not have had any injections or blocks within 4 months of enrollment a…

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.
