Measurement of intraocular pressure. Non-contact tonometer of intraocular pressure.
The difference in the rate of addition and dehydration of moisture in the chambers of the eye gives intraocular pressure. The former provides moisture secretion via the ciliary body processes, the latter is controlled by resistance in the outflow system-the trabecular network in the anterior chamber corner3.
Everything humanity's dream is being reduced catastrophically. The number of ophthalmology patients is steadily increasing. The cause of the illness is dysfunction of the endocrine system, excessive drug consumption, genetic predisposition, inadequate diet. In certain situations, regulation of the intraocular pressure is important.
Intraocular pressure is the pressure which exerts the contents of the human eyeball on the cornea and sclera (ocular membrane). Intraocular pressure facilitates the microcirculation of substances in tissues, and is involved in metabolic processes that include the eye's optical system's basic properties. The intraocular pressure is not gender related.
Measurement of intraocular pressure is a critical step in the test if different pathologies are suspected. The work assists in making a preliminary diagnosis, and monitoring progress in recovery. For example, eye hypotension (decreased V.d.) against uveitis of different etiologies or retinal detachment can be the cause of visual impairment. Glaucoma can cause eye hypertension (elevated VD).
Why is intraocular pressure control necessary?
If asked about assessing eye pressure, patients often respond that all is in order with blood pressure. These are two entirely different dimensions in which measures do not necessarily represent signs of the same things. Regularly regulated blood pressure helps prevent numerous chronic illnesses, heart attack, stroke, and intraocular pressure monitoring allows for early diagnosis and treatment of vision disorders and eye conditions that may have permanent effects, like vision loss.
Methods for measuring intraocular pressure
Palpation through the eyelids allows for a preliminary evaluation of the pressure and an appreciation of whether major deviations from the standard actually occur. The effect of the palpation is determined by the degree of hardness of the pupil, depending on the sound.
The instrumental tests are more precise. There are many radically different forms of blood pressure control, including the touch and non-contact approach for intraocular pressure measurement. Every hardware tonometry uses the concept of the relation between the force exerted by pressure to deform the cornea, and V.d. The difference lies in the methods of application of effort and the methods of measuring results.
Methods for measuring intraocular pressure
Non-contact tonometry is a machine calculation whose concept is based on the corneal reaction under the influence of air flow. This considers the degree and rate of corneal transition. The non-contact approach is the most gentle and non-traumatic, there is no direct contact with the patient's eye and adverse results, no chance of infection. The treatment takes a few seconds, the patient doesn't need to be careful, he doesn't feel anxious.
Applanation tonometry is an intraocular pressure calculation dependent upon the Amber-Fick law. Under this rule, internal pressure is defined as the relation of external force to the size of the area of impact.
Impression tonometry-corneal indentation with a rounded end thread. The approach is essentially used with elevated V.d. And for calculating pressure with curved corneal surface when detecting a wide area is difficult.
