Retinal degeneration Pigmented Peripheral

Retinal periphery degeneration (RPD) is a group of inherited diseases caused by developmental disorders and pathology of the functional photoreceptor cells (rods and cones) in the retina. The pathology has a characteristic distribution and structure.

Peripheral retinal degeneration (PRD) is the most common type of PRD disease. It is often associated with problems that lead to vision loss, namely blindness and amblyopia.

There are 4 types of PZ: - Early PZ or pigment PZ (RPP), - Late PZ - Diabetic PZ (DPP). - PZ of neurobitranamental type. But most patients enter the stage of early PD between the ages of 25 and 35 years.

Early vision loss is characterized by the presence of two types of cells—light and dark—the decrease in functionality of which leads to progressive deterioration of vision. Intraoral examinations reveal a significant number of retinal cells in the retinal plane, which are normally located in the focal zone of light emission, i.e., in the center of the eyeball. These cells belong to the group of photoreceptor cells and are no less sensitive to light than rods and rods. They, unlike sticks, are extremely sensitive to darkness. As a result, in such cells the rate of photochemical reactions increases as much as possible, an avalanche of stick and loset generators occurs, which manifests itself in a drop in visual acuity after a bright day, when loset cells are actively absorbed

Peripheral retinal degeneration is a disease of the retina that occurs as a result of a violation of pigment metabolism in the photoreceptors of the retina and can lead to a significant decrease in vision.

The degeneration may affect only a small part of the retina, but over time it can progress to complete loss of vision. If the disease is not treated, it can cause the development of cataracts and glaucoma.

The main causes of the disease include genetic factors, as well as exposure to radiation, sunlight, chemicals and toxins.

Symptoms of the pathology manifest themselves in the form of distortions and distortions in color perception, which can be noticeable both during eye movement and during static fixation. As a result of these symptoms, a person may experience difficulty with spatial orientation and may experience problems in daily life.
