Tonometry - measurement of intraocular pressure (pressure inside the eye). The instruments used in tonometry, with a small force, deform the surface of the cornea, which is used to calculate intraocular pressure.
With ultrasound biomicroscopy (UBM) of the anterior segment, high-frequency sensors (50 MHz) are used to obtain high-resolution images (approximately 50 μm), which allow you to see the anterior segment of the eye in vivo (penetrating depth - 5 mm)
Gonioscopy is a very important examination method for diagnosing and monitoring the treatment of patients with glaucoma. The main task of gonioscopy is the visualization of the configuration of the anterior chamber angle.
In a broad sense, psychophysiological testing means a subjective evaluation of visual functions. From a clinical perspective for a patient with glaucoma, this term refers to the perimetry for evaluating the peripheral vision of the eye.
Drops can be instilled in various ways. Method using two hands. The patient should tilt the head back so that his gaze is directed upwards.
It has been established that the goal of the treatment of glaucoma is to prevent the further development of symptomatic vision loss with the maximum reduction of side effects or complications after surgical interventions.
Glaucoma - a common cause of blindness in all countries, can develop in any age group, but especially often after 40 years. Increased intraocular pressure is the most important causative risk factor for glaucoma, but high intraocular pressure is not necessary for the development of glaucomatous lesions.
Dual Frequency Perimetry (WELCH) technology (Welch Allyn, Skaneateles, NY, and Humphrey Systems, Dublin, CA) serves to provide an effective early assessment of the visual fields and the detection of glaucomatous changes in the visual fields.
With short-wave automatic perimetry (SWAP), the sensitivity of glaucoma lesions diagnostics is higher in the early stages than with the standard automatic perimetry.
Electroretinography objectively establishes a dysfunction of the retina. With multifocal electroretinography, focal responses are obtained from a large number of retinal sites and topographic maps of zones with a disturbed function are constructed.
