Bilateral retinal hemorrhages and disk edema in migraine.

A 27-year-old patient with severe migraine developed bilateral disk edema and retinal hemorrhages during a prolonged attack of his illness, lasting at least two months. The combination of bilateral disk edema and diffuse superficial retinal hemorrhages was considered to be a manifestation of prolonged valsalva efforts accompanying the migraine attack and of not persistent raised intracranial pressure.
