Botulinum Toxin A for the Treatment of Photophobia and Dry Eye

Photophobia is a chronic debilitating condition that, in severe cases, causes individuals to become prisoners in their own homes. Despite diminishing quality of life, few studies have evaluated therapies for photophobia. Anecdotally, botulinum toxin A (BoNT-A) was reported effective in the treatment of 3 patients with medication-refractory photophobia.1 In this cross-sectional retrospective study, we evaluate the effect of BoNT-A on photophobia and dry eye symptoms in individuals with chronic migraine (CM) and evaluate factors predictive of a positive treatment response.
