Neuro-ophthalmic emergencies are rare. Although their incidence is much lower than other ophthalmic emergencies, such as retinal detachment or ruptured globe, their outcomes carry a much higher morbidity and even mortality. The ocular manifestations of neuroophthalmic emergencies may be predictors of more dangerous central nervous system or systemic pathology. The vision threatening and potentially life-threatening nature of these disorders requires prompt recognition and diagnosis on the physician's part. A delay of even a few hours could result in a dire outcome. Therefore, the clinician must be familiar with the manifestations of these disease entities and initiate appropriate testing and treatment without delay 1.
