A team of researchers, led by Tara Alvarez, recently published a study in the British Journal of Sports Medicine that showed an effective way to treat some of the most common post-concussion disorders. These disorders, known as convergence insufficiency and accommodation insufficiency, cause double and blurry vision, respectively. These eye problems are one of the biggest issues for most people with post-concussion symptoms, and can impair the ability to do tasks such as reading books, working on computers, or driving.
The data showed that after 12 weeks of vision therapy, almost 90% of patients could see normally, compared with under 10% in the control group over the same period. The team also found that typical exercises to strengthen and coordinate eye muscles were just as effective in patients with head injuries as in non-concussed patients. The results of this study will be used to develop standardized protocols for post-concussion vision therapies. This new data is a promising step toward making treatment for these conditions more attainable for the many affected patients who currently face barriers such as cost, time commitment, and availability.
