The normal operation of the optical ocular system occurs with a good turgor of the ocular membrane, the correct spherical shape of the eye. These functions provide intraocular pressure. The fluid inside the eye is an important source of nutrition for the organ. By circulating, it provides metabolism. Eye pressure changes periodically. Fluctuations are rhythmic and irregular. Rhythmic associated with pulse, respiration, vascular changes. Manifest themselves seasonally, as well as during the day. Irregular changes in eye tone occur due to excessive contraction of the eyelids, pressure on the eyeball, sudden changes in blood pressure.
Intraocular pressure. Symptoms
An increase in intraocular pressure negatively affects human health. Particular attention should be paid to the following symptoms: blurred vision, severe headaches in the eye, temple, redness of the eyeball, blurred vision. All these factors can indicate the development of a serious disease - glaucoma. Eye pressure must be controlled. Otherwise, destruction of the optic nerve may occur, leading to blindness.
When intraocular pressure rises, symptoms occur due to the accumulation of a large amount of fluid inside the eye. Normally, eye pressure ranges from 9 to 22 mmHg. In this case, the round shape of the eyeball is well preserved. The amount of incoming fluid should be equal to the amount of fluid leaving. Violation of the circulation leads to its accumulation inside the eye, increased intraocular pressure, the symptoms will not take long. The deformation of thin capillaries occurs and the health situation worsens.
Increased intraocular pressure. Symptoms
There are times when the disease does not appear immediately. The patient may not feel intraocular pressure, the symptoms are "sleeping." Therefore, it is necessary to conduct a periodic examination by an ophthalmologist. Especially for older people (from forty years old and above), it is advisable to check vision and pressure at least once a year.
Currently, intraocular pressure is determined using a special device. Considering its light load on the eye and, consequently, the increase in pressure, the interval from 17 to 26 mmHg is considered a normal indicator. If increased pressure is detected, the symptoms indicate this, then we can talk about the danger of developing glaucoma. No methods have yet been found to cure such a disease. However, it can be paused for a long time. In this case, drugs are used.
Examination of the patient reveals a form of glaucoma. It is open-angle and closed-angle. The closed-angle shape is characterized by the overlap of the peripheral iris of the anterior chamber of the eye. Clamping of the fluid exit channels in the drainage system of the eye occurs. With an open-angle shape, the drainage system itself is destroyed. Such glaucoma is the most insidious. It does not immediately appear. Its asymptomatic course leads to the identification of the disease in the later stages. During this period, the onset of severe pain in the eye in the evening. Spasm gives into the temple, vision is fogging. When looking at the light, rainbow circles appear. With such symptoms, you can not delay in any case. It is urgent to go to the doctor.
Intraocular pressure. Treatment
A person with glaucoma should get used to the idea that he will have to live with this disease all the time. It is chronic. Therefore, you need to calm down, put up with it and control eye pressure using medications and following the recommendations of a specialist doctor. Usually prescribed eye drops that need to be instilled throughout life. There are cases when glaucoma stops in old age, the condition of the eyes normalizes and the doctor cancels the use of drops.
With glaucoma, internal preparations can also be prescribed: diuretics; agents that optimize cerebral blood circulation, metabolic processes in the tissues of the eye. Surgical intervention is also indicated for glaucoma. The modern technique is very effective in operations. Therefore, it is necessary to strictly follow the advice of a doctor and not refuse the proposed method of treatment.
