[Clinical aspects of hypophyseal diseases from the viewpoint of the ophthalmologist].

The anatomy of the chiasmal region and the visual symptoms due to pituitary tumors will be presented from the viewpoint of an ophthalmologist. The importance of perimetry in every patient with otherwise unexplained loss of vision is stressed. Other tests (swinging flash light test, colour vision, screening ophthalmoscopy) are mentioned as well. An ophthalmologist should participate in the diagnosis as well as in the follow-up after treatment of any case with pituitary tumors.
