ANN ARBOR, Mich., June 7 (UPI) — Four U.S. physicians found prismatic eyeglasses reduced brain injury headache symptoms by 79 percent.
The doctors suggested headache, dizziness and anxiety in some patients with traumatic brain injury could be alleviated or even eliminated with the use of specialized eyeglass lenses containing prisms.
The prisms correct visual image misalignment that causes double vision. This condition — known as vertical heterophoria — causes eye muscles to become strained and overworked and has been linked to headaches, dizziness, anxiety and neck pain.
Study co-authors Dr. Jennifer Doble, a rehabilitation specialist at Ann Arbor’s St. Joseph Mercy Hospital, and Dr. Debby Feinberg, a Birmingham, Mich., optometrist, first recognized a patient with traumatic brain injury having vertical heterophoria in 2005.
The study, published in Physical Medicine and Rehabilitation, involved 43 patients with traumatic brain injury having post-concussive symptoms for more than three years despite treatment who were diagnosed with vertical heterophoria.
“Treatment of the vertical heterophoria with prismatic eyeglass lenses was found to be effective in reducing symptoms associated with both traumatic brain injury and vertical heterophoria,” study co-author Dr. Arthur J. Rosner, an otolaryngologist at William Beaumont Hospital in Troy, Mich., said in a statement.
