[Transient binocular visual loss: a diagnostic approach].

It is rarer for a patient to present with transient binocular visual loss than transient monocular visual loss. This symptom usually results from a cerebral dysfunction. When transient binocular visual loss results from papilledema, ophthalmological examination is critical for an accurate diagnosis. In other cases, examination may be normal and a thorough history is of paramount importance for making a diagnosis and deciding whether or not imaging is necessary. The three main cerebral causes for transient binocular visual loss are migraine with visual aura, partial seizures occurring in the occipital lobe, and vertebrobasilar ischemia.
