Anomalous optic discs may be associated with relative temporal visual field defects that need to be distinguished from bitemporal field defects of chiasmal compression. Two patients with both anomalous discs and suprasellar tumors were hospitalized with temporal hemianopic scotomatous visual field

OBJECTIVE
In order to evaluate the relationship between the orbital neoplasms and the resulting visual field damage.
METHODS
22 cases of orbital tumors and tumor-like lesions were examined with automated perimetry.
RESULTS
Visual field alterations varied from arcuate, inferior altitudinal,
Junction scotoma and involvement of the optochiasmal junction.

Log In/Sign up
In two patients, ipsilateral central scotoma and contralateral superior temporal hemianopic field defect indicated involvement of the junction of the optic nerve and chiasm, the optochiasmal junction. In both cases, computed tomography and carotid angiography confirmed mass lesions at this location.

Pituicytomas are rare neoplasms of the sellar region. We report a case of vision loss and a junctional scotoma in a 43-year-old woman caused by compression of the optic chiasm by a pituitary tumor. The morphological and immunohistochemical characteristics of the tumor were consistent with the
