[The nonfunctional pituitary adenoma, The optic chiasm syndrome].

We present the case of patient D. E., 48 years old, whose diagnosis is nonfunctional pituitary adenoma. The diagnosis was revealed by the presence of bitemporal hemianopia. This observation led us to remember the principal neuro-ophthalmological manifestations and to emphasize the part of the ophthalmologist in the diagnosis of this disease.
