Homonymous hemianopsia
Homonymous hemianopsia
Homonymous hemianopsia (pronunciation: ho-mo-ny-mous he-mi-a-nop-sia) is a medical condition characterized by the loss of half of the field of view on the same side in both eyes. The condition can occur as a result of stroke, brain tumor, trauma, or neurological disorder.
Etymology
The term "homonymous hemianopsia" is derived from three Greek words: "homos" meaning same, "hemi" meaning half, and "anopsia" meaning blindness. Thus, it literally translates to "same half blindness".
Symptoms
Patients with homonymous hemianopsia typically experience a loss of vision in half of their visual field. This can affect one or both eyes and can lead to difficulties in reading, driving, and recognizing faces. Other symptoms may include difficulty in navigating through unfamiliar environments and bumping into objects on the affected side.
Causes
Homonymous hemianopsia is most commonly caused by stroke, particularly those affecting the occipital lobe of the brain. Other causes can include brain tumor, trauma, or neurological disorders such as multiple sclerosis.
Treatment
Treatment for homonymous hemianopsia is primarily focused on addressing the underlying cause of the condition. This may involve medication, surgery, or rehabilitation therapies such as visual field training and compensatory strategies.
