Compendium taken from Cephalagia © International Headache Society 2003.

Visual field defects depend on the location of the disturbances in the visual pathway. Field defects in retinal migraine correspond to the one shown in (A) but not in (B-D).

Visual disturbances are typical (though not necessary) symptoms in two thirds of any migraine subform. However, the set of diagnostic criteria that must be fulfilled does not differentiate between the various visual symptoms, except for two subforms including 1.4 retinal migraine (the other subform being 1.2.6 basilar-type migraine). In the classification it is commented that "[s]ome patients who complain of monocular visual disturbance in fact have hemianopia" pointing at the complexity of a verbal description. The development of computer-assisted procedures may establish easier diagnostic criteria. [more]
