Cranial Nerves: Abnormal Findings

Cranial Nerve 2- Optic nerve

Video: Right homonymous hemianopia (right-sided visual field deficit)

Description: The patient's visual fields are being tested with gross confrontation. A right sided visual field deficit for both eyes is shown. This is a right hemianopia from a lesion behind the optic chiasm involving the left optic tract, radiation or striate cortex.

Note: Visual field testing can be done in different ways by different physicians. This video shows a slightly different method of visual field testing than in the demonstration video clips and in your courses. For the present, you should learn to do the testing as demonstrated by your instructors.
