Ocular symptoms are a common, though transient, initial component of migraine. Although permanent visual loss has been reported in a limited number of patients, detailed evaluations of the visual field using current techniques have not been conducted. This study examined the prevalence of visual field loss in patients with migraine, using an automated static perimeter. All patients had at least a 2-year history of migraine (as diagnosed by a neurologist) and no ocular problems (by history or as determined by a visual screening examination consisting of acuity, intraocular pressure [IOP], and evaluation of the disc). The authors' results for 60 migraine patients showed that 21 (35%) had some form of visual field abnormality (P < 0.05). The prevalence of visual field loss was greater with increasing age and duration of disease. These results suggest that visual field loss from migraine may be more common than previously considered. This information also may be useful in elucidating the relationship between migraine and certain vascular conditions of the eye.
