Ophthalmoplethysmograph

**Ophthalmoplethysmography and computer study of perimetry.** Many of you have heard about studies that are carried out using an ophthalmoplethysmograph, a device that allows you to study the tone of the vessels of the eye by compressing them from the sides and thus causing changes in blood flow and an ophthalmoplegic reaction - increased heart rate, increased blood pressure pressure. Having studied the hemodynamics of the vessels of the eyeball, one could assume that the studies would be useful for assessing the blood supply to the retina. However, in fact, they are only interesting in connection with the general human vascular pathology. The space in the anterior segment of the eye is divided into three regions, the so-called ciliary veins (Q1), the pinguecula region, the region of the iris and ciliary muscle (Q3) and the choroid (Q2). Each region consists of at least three vascular regions and can be examined separately. Usually only the main sections corresponding to most areas of the human eye are examined. Each individual zone is examined, regardless of location. Currently, everyone who is in contact with this problem has information about studies that can be carried out to assess the condition of the optic nerve, such as “electrical sensitivity threshold study” (EST), “visual
