Vertical Heterophoria Clinical Trial
Official title:
Utility of a Survey Instrument to Predict Benefit From a Novel Treatment for Vertical Heterophoria
Patients with acute exacerbation of chronic headache disorder present frequently to the
Emergency Department (ED) for pain management. A novel etiology of headaches is Vertical
Heterophoria (VH), a poorly understood and little recognized binocular vision malady that
when treated with realigning prismatic spectacle lenses results in marked reduction in
headache and other associated VH symptoms.
This study aims to determine the accuracy of the Vertical Heterophoria Symptom Questionnaire
(VHSQ) in identifying a ED headache patients who will experience significant reduction in VH
symptoms with use of realigning prismatic spectacle lenses. This study's secondary purpose is
to determine if VH is a common cause of chronic headache disorders in ED headache patients.
To achieve these goals, a prospective observational study will be performed on ED headache
patients > 18 years old. All will be given the VHSQ, and all will be assessed for a diagnosis
of VH by an optometrist who will utilize a novel VH testing method. High and low score groups
on the VHSQ will then be compared to each other to determine the prevalence of VH in each.
