Intraocular pressure is formed due to the location of the capsule within the aqueous humor and vitreous humor. They put pressure on the capsule inside and create the overall tone of the eye, or, in other words, human intraocular pressure. Due to the intraocular pressure is provided by the power of his eyes and maintained a spherical shape.
Reduced or elevated intraocular pressure - serious ophthalmological diseases. They lead to a deterioration in visual function. Without proper treatment of intraocular pressure can irreversible changes in the eye tissues.
It causes increased intraocular pressure increased production of intraocular fluid, innate anatomical features of the structure of the eye or malfunctions of the cardiovascular system of the person.
Low intraocular pressure occurs much less frequently. It can cause underdevelopment of the eyeball, trauma or post-operative complications. When reduced intraocular pressure disturbed nutrition eye and may die eye tissue.
Preventive measure intraocular pressure is recommended 1 time in 3 years for people over 40 years old. Modern diagnostics is able to prevent the development of disease complications and reduced elevated intraocular pressure - glaucoma, optic nerve atrophy, etc.
Measurement of intraocular pressure
Intraocular pressure measurement procedure called tonometry. It is performed using a tonometer Maklakov, pneumotonometry or elektrotonografii.
The most common method of measuring intraocular pressure is tonometer Maklakov. During the procedure, the center of the cornea of the patient established special painted weights. Their typos later measured and deciphered. Thanks to local anesthesia tonometry painless, but gives a lot of discomfort.
Normal intraocular pressure is dependent on the type of measuring device. When measured with a tonometer Maklakova rate of intraocular pressure is up to 24 mm. Hg Performance standards intraocular pressure measured by pneumotonometry admit only figures 15 - 16 mm Hg
Using modern methods elektrotonografii above normal intraocular pressure is diagnosed based on a set of enhanced production of intraocular fluid, as well as its rapid outflow.
Symptoms of elevated intraocular pressure
At elevated intraocular pressure symptoms may be absent altogether. Sometimes, increased intraocular pressure is accompanied by pain in the temples or eyes. In more rare cases, the symptoms of intraocular pressure include blurred vision, and eye redness. A slight excess of the rate of intraocular pressure may also exhibit enhanced visual fatigue.
Acute glaucoma attack with a sharp excess of the norms of intraocular pressure manifested intense pain, nausea, vomiting, puffiness of eyelids and corneal opacity.
Treatment Intraocular pressure
The conservative treatment of intraocular pressure applied drops, improve nutrition eyes and drainage function of the body. Dosage and duration of treatment of intraocular pressure are assigned individually.
With the lack of effectiveness of conservative treatment of intraocular pressure of the patient is recommended to perform a laser iridotomy or laser trabekulospazisa.
During laser iridiktomii iris is formed on one or more openings. This method of treatment the intraocular pressure can improve circulation and fluid outflow from the eye, and ultimately normalizes elevated intraocular pressure.
Laser trabekulospazis performed for better drainage of the eye due to the stretching of the venous sinus of the sclera. During this technique, laser treatment of intraocular pressure cauterizing the base of the ciliary body of the eye.
The most radical method of treatment of intraocular pressure - microsurgical techniques: goniotomiya with or without goniopuncture and trabekulotomiya. When dissected goniotomii iridocorneal angle of the anterior chamber of the eye. Trabekulotomiya, in turn, represents a dissection trabkulyarnoy mesh eyes - tissue connecting iris ciliary edge to the rear plane of the cornea.
