Neuro-ophthalmological evaluation revealed that the patient had slight bitemporal hemianopsia
Visual field defect is most frequently in the form of bitemporal hemianopsia and superior temporal defect.
Bitemporal hemianopsia and superior temporal visual field defect are found most frequently.
The most common visual field disturbance is bitemporal hemianopsia
, and contiguous spread of the tumor to the adjacent cavernous sinus most commonly produces cranial nerve III and IV dysfunction (1).
1-3) Lesions in these areas cause symptoms and signs by slow enlargement and compression of the hypothalamus and optic apparatus and the intraventricular foramen, leading to headache, visual disturbances such as bitemporal hemianopsia and hydrocephalus.
Formal visual field examination in May 1999 showed a bitemporal hemianopsia, worse on the left (Fig 1).
A 42-year-old man presented with bitemporal hemianopsia
and decreased visual acuity.
A 44-year-old woman presented with dizziness, headache, and progressive bitemporal hemianopsia
for about 1 month.
