Ophthalmological Symptoms in Tumors of the Sellar Region
The chiasmatic syndrome is typical of tumors of the sellar region. Visual field defects, impairment of visual acuity, and optic atrophy are the consequences of a conduction defect in the chiasm or the adjacent parts of the optic nerves or tracts. This is why most of these patients are first seen by the ophthalmologist, who determines on the basis of perimetry, examination of the visual acuity, and ophthalmoscopy whether this process is growing mostly in the sella or above it or laterally in the parasellar region.
