PRONUNCIATION OF HEMIANOPSIA Hemianopsia A vision loss involving half the normal visual field in one or both eyes is called hemianopsia. This visual field defect usually results from a lesion on the optic pathway in the parietal or temporal lobe.

- Hemianopsia is a loss of vision in half of the visual field of one eye or both eyes. Common causes are stroke, brain tumor, and trauma to the brain. Normally, the left half of the brain receives vision from the right eye, and vice versa.Information from the optic nerves crosses to the other half of the brain using an X-shaped structure called the optic chiasm.ommon causes are stroke, brain tumor, and trauma to the brain.

- BACKGROUND: Hemineglect is a difficult neurologic condition to rehabilitate. It arises predominantly from right brain injury, and manifests heterogeneously in clinical deficits such as poor visual exploration to the left, inaccurate assessment of the midpoint of a line, left limb hypokinesis, and anosognosia.

The Effects of an Occipital Lobe Stroke Visual Changes After Occipital Lobe Stroke. Homonomous Hemianopia- Stroke Affecting the Entire Occipital Lobe on One Side; When the stroke affects most of the occipital lobe on one side of the brain, the visual problem that arises is called homonymous hemianopia. This describes loss of half of the vision out of each eye. A stroke survivor who has homonymous hemianopia is not able to see objects that are on the opposite side of the stroke.

Hyphema (Bleeding in Eye) Hyphema (Bleeding in Eye) Overview. Blunt trauma to the eye can cause bleeding in the front (or anterior chamber) of the eye between the cornea and the iris. This bleeding into the anterior chamber of the eye is called a hyphema. The anterior chamber of the eye contains a clear liquid fluid called aqueous humor. The aqueous humor is secreted by the ciliary processes in the posterior chamber of the eye. The aqueous humor passes through the pupil into the anterior chamber.

- This type of side vision loss is called Hemianopsia (hemi field loss). Patients who just have a hemianopsia are aware of the side vision loss and often can be easily taught to scan their eyes in the direction of the hemianopsia, in order to compensate for the field loss.
