title: [Necessary pressure in the ophthalmic artery].
abstract: As a result of an acute pathologic event ophthalmic arterial pressure may fall below a level necessary to supply sufficient blood to the eye and optic nerve, and thus to preserve full visual function. A sudden partial or even total loss of visual function. A sudden partial or even total loss of vision may follow. In such cases an early therapeutic elevation of ophthalmic arterial pressure to a value above this critical level may improve or even normalize visual function within a surprisingly short period of time.
