Binocular Vision Function and Migraine: A Review

Migraine is a multifactorial disease characterized by recurrent headaches and has complex neuronal and vascular mechanisms, including a wide range of clinical symptoms and other ocular findings. During migraine attacks in migraine sufferers, the accommodative response increases significantly. Migraine sufferers are predisposed to have a subtle deficit in binocular vision coordination, reduced stereopsis, reduced fixation disparity, slightly higher prevalence of heterophoria, and reduced stereopsis. Convergence insufficiency can be associated with migraine and may be the persistent cause of reduced visual functioning. Binocular vision coordination difficulties are the most common findings among migraine sufferers.
