Summary

Patients with migraine may experience visual hypersensitivity. Individually prescribed colored filters effectively reduced pattern glare and symptoms in a study, suggesting a potential treatment for visual triggers in migraine.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Optometry

Background:

  • Migraine patients often report visual stimuli triggering headaches.
  • Evidence-based research on visual triggers and treatments for migraine is limited.
  • Colored filters are hypothesized to help migraineurs with visual hypersensitivity.

Purpose of the Study:

  • To investigate the optometric characteristics of migraine patients.
  • To identify visual factors contributing to migraine symptoms.
  • To evaluate the efficacy of tinted lenses in managing visual stimuli in migraine.

Main Methods:

  • Compared 21 migraine patients with 11 controls.
  • Assessed refractive error, ocular pathology, color vision, contrast sensitivity, accommodation, and phoria.

  • Investigated the impact of precision tinted and control tinted lenses on pattern glare.

    • Main Results:

    • No significant differences found in most optometric parameters between migraineurs and controls.
    • Migraine group showed increased susceptibility to pattern glare (p = 0.004).
    • Tinted lenses significantly improved pattern glare in the migraine group.

    Conclusions:

    • Migraine patients exhibit normal optometric characteristics but are more prone to pattern glare.
    • Individually prescribed colored filters may alleviate cortical hyperexcitability and pattern glare.
    • Tinted lenses show promise as a treatment for visual stimulus-induced migraine symptoms.
