Most often, the patient loses the mobility of the limbs, but it may also require restoration of vision after a stroke. The degree of brain damage affects the prognosis of therapy, careful adherence to the recommendations of the attending physician.
Sight loss with stroke
In fact, partial or complete loss of vision after a stroke is quite common, occurring in approximately one third of patients affected by the disease. With small volumes of damage to areas of the brain, there is a gradual restoration of visual function.
Volumetric necrotic phenomena lead to various eye problems, up to its complete loss. In such cases, a combined course of therapy is required: taking medicine and attending rehabilitation classes.
The effect of stroke on vision
A stroke is an acute damage to the cerebral blood supply as a result of blockage or loss of vascular integrity. The consequence of pathological disorders is the development of irreversible necrotic and atrophic phenomena, and as a result, the loss of certain functions.
If the pathology affects areas of the brain that are responsible for vision, temporary or permanent blindness, strabismus, or other abnormalities develop.
The symptoms can determine which part of the brain is affected, as well as the degree and extent of necrotic phenomena:
- Loss of visual fields indicates a small amount of localized lesion. This disorder is often referred to as a “blind spot.” With relatively clear visibility there is a small area that falls out of sight. In this case, as a rule, the eyes hurt. With a small amount of necrotic phenomena, the vision after a stroke is restored independently, as the patient rehabilitates. You may need to visit exercise therapy and perform exercises for the eyes.
- Lack of peripheral vision – two lobes of the brain, right and left, are responsible for visual functions. Visual information from the left side of the retina of both eyes enters the right-side site. Similarly, information from the left side of the retina is processed by the right lobe of the brain. If the lateral vision disappears, it means that the brain tissue is seriously damaged. It is possible to restore lateral vision due to intensive therapy and the ability of intact brain tissue to take over some of the lost functions.
- The paralysis of the oculomotor nerve occurs due to atrophic events affecting the fibers and muscles that control eye movement. As a result of the disturbances, the patient is not able to look straight. Eyes look in different directions, there is a protrusion of the visual apple, squint.
Why the stroke does not open the eyes
The reason why eyes do not open after a stroke is in the lesion of the optic nerve located in the anatomical proximity with different sections and parts of the brain. Tissue damage due to hemorrhage or coronary artery disease affects the structure of the oculomotor nerve, which passes at the level of the superior collicus of the midbrain, between two large arteries.
As a result of pathological disorders, the following negative manifestations of stroke are observed:
- Split vision – the inability to control the direction leads to a protrusion of the eyeballs and their unfolding to the side, which is manifested in violations of visual perception.
- Atrophy of the optic nerve due to a stroke – the patient’s eyelid spasms, there is a tremor in the eyeballs. Severe violations for the most part are irreversible. The patient is prescribed visual impairment. With relatively small necrotic and atrophic events, it is possible to achieve certain improvements, regarding changes and eliminate the consequences after a stroke.
- Eye bulging is another characteristic symptom of the oculomotor nerve atrophy. After a stroke, paralysis occurs in the eyes, the main functions are disturbed. The constant tension exerted on the eyeball leads to a condition in which the eyes constantly water, which indicates dryness of the cornea. If urgent measures are not taken, the vision may fall and the changes become irreversible.
How to restore vision after a stroke
Poor vision is an unpleasant companion of a stroke or cerebral infarction. The consequence of intracranial hemorrhage or acute lack of blood supply is the atrophy of the ocular and oculomotor nerve.
If you do not resort to a course of drug and restorative therapy, vision after a stroke will not return soon.
Ways to restore the lesion of the oculomotor nerve after a stroke are in three main areas:
- Drug therapy.
- Ophthalmic gymnastics.
To shorten the recovery period of vision, it is also recommended to use non-traditional methods of treatment of the optic nerve.
Preparations for restoring vision
Medicines for restoring vision are prescribed depending on the clinical manifestations of stroke. If disorders are associated with dysfunction of the brain tissue, complex therapy is appointed, aimed at improving the blood supply and metabolism of nerve cells.
Specific ophthalmic preparations are not required, but eye drops may be prescribed to maintain the functionality of the eyeball.
In a situation where the atrophy of the optic nerve is the cause of the defocusing of vision, it is necessary to prescribe a course of drug and restorative therapy aimed at restoring normal blood supply and tissue functions.
Along with traditional medicines, homeopathic medicines are used for visual impairment after a stroke. The principle of homeopathy is based on the activation of the body’s own reserves to combat pathological changes.
In situations where the chosen method of restoring oculomotor disorders does not give a positive result, an operation is scheduled.
How to restore the sight of folk remedies
The restoration of vision after a stroke at home using folk remedies is a fairly common practice. It is impossible to argue against non-traditional methods, especially if they are used after completing a course of traditional therapy.
Unconventional methods of treatment of the optic nerve reduce the recovery time of vision, help reduce the likelihood of deterioration of the patient’s health. Traditional medicine in the first place draws attention to changes in the patient’s diet, as well as the use of herbal tinctures and decoctions that improve blood flow.
The following plants are used in therapy:
- Pine, spruce and cedar cones – help tinctures, decoctions and even jam. Large amounts of biologically active elements in the cones, improve blood flow to the atrophied area and clean the vessels.
- Mountain arnica – it is believed that the plant increases the possibility of restoring peripheral vision as a result of a partial stroke, and also has a good preventive effect during the fight against the disease.
- Lemon with garlic – eliminates double vision during a stroke. Vitamin C (part of all vitamins to restore vision) eliminates the fragility of blood vessels and helps to restore their elasticity.
Gymnastics for the eyes
Exercises for the eyes are simple, so after a few lessons with an instructor, you can start doing them at home on your own. Gymnastics complex is aimed at restoring motor and visual function. Exercise therapy for the eyes will benefit only if the simultaneous intake of vitamins and medicines, as well as regular exercise.
One of the effective exercises is the following:
- Three fingers should lightly press the upper edge of the eye.
- It is necessary to move the fingers towards the temples from the tip of the nose, exerting a slight pressure on the eyeball.
- The exercise is repeated for each eye 3 times.
Over time, with complex therapy, beneficial changes will become apparent. Sight recovery will be slow, so expect quick results are not worth it. But with patience, you can restore the visual function in due measure.
