Hemianopsia Heteronymous

Heteronymous hemianopia is a form of visual impairment in which the patient cannot see one half of the visual field. This form of visual impairment is very common and can be caused by a variety of reasons. Heteronymy is associated with the lack of the ability to perceive an image on one half of a person’s visual field. This is because this part of the visual field is on the opposite side of the brain to the one on which the functionally active laterality is located. The patient perceives information in the field of view only from the healthy half.

If a person develops heteronymous hemianope, his ability to perceive the surrounding world in a certain part of the visual field, located in the half of the visual field distant from the patient, is impaired. He believes that his half of the visual field differs in some way from the visual field of other people, that is, asymmetric errors occur in assessing size, shape and color.
