Thin Film Spectacle Coatings to Reduce Light Sensitivity and Headaches in Child and Adolescent Patients With Migraine

This study is currently recruiting participants. (see Contacts and Locations)

The purpose of this study is to determine if a special coating, applied to the surface of glasses can reduce the frequency and severity of migraine headaches in children and adolescents. This study is being conducted by researchers at Primary Children's Medical Center, The John Moran Eye Center, and the University of Utah Department of Electrical Engineering. The investigators have determined that a specific frequency of light is particularly bothersome to migraine patients. The coating they've developed is designed to block this frequency of light. Very few treatments are approved for the treatment of childhood migraine. The investigators hope that these glasses will provide a safe way to improve headaches in children.

Primary Outcome Measures:
  • HIT-6 Score [ Time Frame: 12 weeks ]
    The HIT-6 (Headache Impact Test) is a validated measure of the impact of headache on activities of daily living, functional health and well-being.

Secondary Outcome Measures:
  • Headache Frequency as Measured Using a Self-Reporting Daily Diary [ Time Frame: 12 weeks ]
    Headache frequency will be assessed using daily headache diary entries provided by subjects

Other Outcome Measures:
  • Headache Severity as Measured Using a Visual Analog Scale and a Self-Reported Daily Diary [ Time Frame: 12 weeks ]
    Subjects will rate the severity of their headaches throughout the study using a visual analog scale as part of a daily headache diary.

Estimated Enrollment: 50
Study Start Date: January 2014
Estimated Study Completion Date: April 2017
Estimated Primary Completion Date: April 2017 (Final data collection date for primary outcome measure)
