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
We report the case of a 44-year-old woman with breast cancer who experienced visual loss and altered color vision after two cycles of chemotherapy with 5 fluorouracil, epirubicin, and cyclophosphamide. She was referred to our Ophthalmology department with suspicion of toxic optic neuropathy.
To optimize orientation and operative exposure for aggressive resection, the authors approached pineal region tumors transtentorially with the patient in a semisitting position. In the current report, 12 consecutive patients were evaluated to document operative ocular morbidity referable to the
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,
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
A 59-year-old male patient presented with clinical characteristics of a melanocytoma of the optic disc in the right eye. Using functional tests, such as visual acuity, visual fields, visual evoked potentials (VEP) and imaging procedures (e.g., fundus photography and spectral domain optical coherence
