SPONTANEOUS HEMATOMA OF THE OPTIC CHIASMA Report of a Case

A case of spontaneous hematoma in the right optic nerve and anterior part of the optic chiasm is reported. Contrary to general conception it gave rise to a homonymous hemianopia. It is suggested that surgical exploration of the chiasm be considered also in cases of unexplained acquired homonymous hemianopia. In the present case surgical removal of the hematoma resulted in restoration of full vision in a preoperatively practically blind eye, but still a homonymous hemianopia was present.
