Glaucoma parameters are measured by evaluating the excavation of the optic nerve disk, the defects of the SNV and, possibly, the ratio of their thickness in the macula. These parameters are reliable signs of glaucoma and its progression.
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.
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.
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.
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)
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.
