简要总结
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.
