Symptoms of hyperopia and methods of treatment of pathology
Hyperopia or hypermetropia is the pathology of refraction, when light rays gather behind the retina and at the same time a blurry image is formed on it, and the symptoms of hyperopia depend on the neglect of the disease process.
Causes of
pathology As a rule, hyperopia develops on the assumption that the eyeball is too small and irregular in shape, it is sort of slightly compressed along the horizontal axis, so the image perceived by the eyes is focused behind the retina, not on it. Often the contraction of the eyeball is complemented by insufficient optical power of the lens and cornea. In rare cases, hyperopia occurs due to the weakening of the optical system in the eye in the presence of a normal shape of the eyeball.
With farsightedness, the patient often squints, trying to help the accommodation process. It is harmful to the eyes, as it provokes the development of complications and a constant tension in the ciliary muscle. With prolonged examination of objects near the patients complain of severe eye fatigue, pain, headaches, burning eyes, lacrimation and slight tingling. An unpleasant sensation also appears when looking at a bright light.
Manifestations of the pathology of
If the hyperopia does not undergo correction for a long time, the eye simply ceases to function, and an irreversible deterioration in visual acuity develops in it. Usually only one eye affects this process.
Due to the constant accommodation, eye reduction to the median axis may occur when viewing objects at any distance - this is how the accommodative squint is formed and if there is no treatment, amblyopia occurs.
Accommodation is more evident when the eyes are working at close range, and a prolonged load on the visual organs provokes the appearance of a sensation of sand in the eyes, rapid fatigue and frequent headaches.
Exactly established signs of hyperopia, in the development of which a person should immediately visit a specialist. These include: deterioration of visual acuity at least on one of the eyes, the formation of strabismus, a sense of rapid eye fatigue and pain in the eye. The sooner the doctor delivers an accurate diagnosis, the more effective will be the treatment, which will prevent the development of complications of pathology.
Hyperopia has three degrees of development, namely:
- Farsightedness of a mild degree.
- of medium degree.
- high degree.
With the development of a weak degree of farsightedness, the affected eye realizes its functions due to the accommodation process. And already with an average or high degree of disease it is supposed to carry out correction of vision both at a distant and at a close distance.
Diagnosis of pathology
The diagnosis of a specialist is usually not particularly difficult, as the doctor knows exactly how to determine the farsightedness. For this, the following diagnostic methods are performed:
- Detection of visual acuity with or without correction.
- Examination of refraction with the help of an indirect ophthalmoscope and rulers, depending on the movement of the shadow in the pupil zone.
- Perimetry.
- Refractometry is the establishment of the ability of the eye to refract.
- Examination of the fundus and ophthalmoscopy using the Goldman lens to diagnose concomitant lesions.
- Ultrasound examination of the eye.
Treatment of pathology
Hyperopia requires compulsory treatment. In addition, it is necessary to begin the healing process at the early stages of the disease, until the vision has become very blurred and has almost lost its clarity. Only in 5 to 8% of all cases of development of pathology, hyperopia is considered incurable, usually this is due to hereditary abnormalities in the development of visual organs.
For the treatment of hyperopia, conservative methods and methods of specific therapy are used.
It will not be possible to eliminate hyperopia only in therapeutic ways, since such independent methods simply do not exist. No drops for the eyes will help to normalize and restore vision, and vitamin medications in any form of release can remain only a means of preventing pathology.
Only surgical intervention can be considered a full-fledged method of completely eliminating farsightedness. The most effective and often used methods of surgical operations include the following:
- Replacing the lens of the eye with an artificial optical size.
- Implantation of lenses inside the eye in the interval between the lens and the iris. This process lasts about fifteen minutes and does not require in-patient treatment. This operation is organized at strong deviations of sight from norm.
- Correction of farsightedness using laser techniques. The risks from the operation and the development of side effects are minimized.
Without the correction of hyperopia, getting rid of it will not work. Often at the first stages of pathology formation, it is enough to use ophthalmic instruments to correct the work of visual organs, the most effective of which are:
- Wearing contact lenses.
- Wearing specially selected glasses.
- Wearing special night lenses.
Preventing the emergence and development of the pathology of
There are several rules, under which the risk of farsightedness decreases markedly:
- Performing the work only under condition of sufficient illumination.
- The correct alternation of labor with rest.
- Implementation of special exercises and a complex of gymnastics for the eyes after every forty minutes of intense exercise.
- Periodic visit to the ophthalmologist and eye examination.
