How Do You Spell CROSSED HEMIANOPSIA?

1. Crossed hemianopsia, also known as crossed visual field defect or bitemporal hemianopsia, is a medical term that describes a visual field defect where there is loss of vision in half of the field of view of both eyes, but on opposite sides. "Crossed" refers to the fact that the loss of vision occurs on the opposite side of each eye.

   In individuals with crossed hemianopsia, the loss of vision usually occurs in the outer, or temporal, half of the visual field of each eye. This means that the individual experiences loss of vision on the outer side of the right eye and the outer side of the left eye. The central vision is usually preserved.

   This condition is typically caused by lesions or damage to the optic chiasm, which is a structure located at the base of the brain where the optic nerves cross over. These lesions may be the result of various conditions, such as brain tumors, aneurysms, or strokes.

   The symptoms of crossed hemianopsia may include difficulty with peripheral vision, reduced depth perception, and problems with navigation and coordination. However, the severity and specific symptoms can vary depending on the underlying cause and the extent of the visual field loss.

   A thorough medical evaluation, including imaging tests, is usually required to diagnose crossed hemianopsia and identify the underlying cause. Treatment options primarily focus on addressing the underlying condition, such as tumor removal, medication to reduce swelling or manage other symptoms, or rehabilitation therapy to improve compensatory visual strategies and enhance quality of life.

2. Heteronymous h., loss of sight in the inner (binasal h.) or the outer (bitemporal h.) half of the visual field of each eye.

Common Misspellings for CROSSED HEMIANOPSIA

The word "crossed hemianopsia" has its etymology rooted in Greek and Latin.

1. "Crossed": The term "crossed" in this context indicates a crossing or intersection of nerve fibers in the brain. It comes from the Latin word "crux" meaning "cross".

2. "Hemi-" : It is a prefix derived from the Greek word "hēmi-", meaning "half".

3. "Anopsia": This word is taken from the Greek word "an-" (without) and "opsis" (vision), denoting a condition or disorder related to a loss or impairment of vision.

Thus, the word "crossed hemianopsia" refers to a visual impairment or loss of vision in the half of the visual field on the opposite side of the brain lesion or damage, leading to a crossed pathway of nerve fibers.
