Hemianopsia Relative

Relative hemianopia: features, causes and treatment

Relative hemianopsia (also known as hemihypopsia) is a visual impairment in which a person cannot see half of the visual field in one eye, but can see that half in the other eye. In other words, relative hemianopsia means the presence of weakened vision in half of the visual field, which corresponds to one eye.

This is different from absolute hemianopsia, in which a person completely loses vision in half of the visual field, and this occurs in both eyes.

Relative hemianopia can be caused by several causes, including strokes, brain tumors, head injuries, and some hereditary diseases. It can also occur due to certain eye diseases, such as glaucoma or degenerative retinal diseases.

Symptoms of relative hemianopsia may vary depending on the cause and location of the lesion. Some people may notice that they cannot see objects that are next to them on one side, or that they cannot read entire lines of text that are located on one side.

Treatment for relative hemianopsia depends on the cause of this disease. Surgery, medications, or rehabilitation measures may help improve vision. Rehabilitation interventions may include eye training, the use of certain optical devices, or even teaching the patient how to use visual cues to compensate for the missing portion of the visual field.

In conclusion, relative hemianopia is a visual impairment that can affect the patient's quality of life. If you suspect relative hemianopsia, you should see a doctor for a diagnosis and determine the best treatment plan.



Relative hemianopia (French hémianopsie relative - symptomatic unilateral loss of vision) is a variant based on a topical symptom, a symptom indicating damage to the cerebral hemisphere opposite to the site of eye damage, due to various diseases of the nervous system innervating this eye. It occurs when the pathological focus is unilateral, often supratentorial. Moving objects looking towards the affected eye also cause hypoesthesia in the ipsilateral abduction of the eyeball. Orientation in space is lost, the lateral friendly deviation of the eyes increases. With cerebral hemiparesis, chronic pain sometimes occurs. as a result of damage to the visual cortex and outer parts of the visual pathway. With symmetrical lesions of the optogestural systems, along with relative pain, also symmetrical ipsilaterally, typical one- and two-sided pain occurs, depending on the time of its appearance (at the first stage - ZBH associated with areflexia, at the second - absent with persisting areflexia ). The subsequent death of visual cells in the middle of the third stage also causes hemiopia, but with each glance at the slide, continuing to lose G.), while maintaining visual and plastic reflexes. The focal nature of its origin can be assumed with weak atrophy of the cerebral cortex, indicating the phasoreflex significance of the sections involved in the occurrence of X.
