Reflex Pupillary Cortical

Cortical pupillary reflex, also known as cortical pupillary reflex or PCR (Pupillary Costric Reflex), is a physiological process that occurs in the eye. The mechanism of its action is associated with the process of light absorption by the optic nerve, which transmits information about the level of illumination to the brain. During sleep or in the absence of visual stimulation, the pupil usually contracts in size, which is the result of the body's active response to limited light output. Conversely, when a flash of light or other visual stimulation occurs, the pupil dilates, becoming larger than its normal size. This process is highly sensitive and is used to determine environmental light levels or test other visual functions. However, PKK can be disrupted as a result of pathologies of the central nervous system, such as trauma or infection of the brain. Violation of the RPC is one of the manifestations of a coma and may indicate a serious pathology of the brain.

Assessment of this reflex has diagnostic value in various fields of medicine, especially in neurology, ophthalmology and psychiatry. To assess RPC, various tests and scales are used, such as the Hudson average light sensitivity test of retinal convergence fixations and others. In addition, testing for PKK plays an important role in assessing the patient's mental conditions, which may occur even without any physical symptoms. Assessing this parameter can help determine the cause of changes in behavioral activity in patients with dementia or schizophrenia. PKC assessment can also be used to detect advanced dementia and other types of disease associated with cortical dysfunction, such as Alzheimer's disease. Some studies have shown that RCCR in patients with Alzheimer's disease decreases over time, indicating possible disturbances in neurochemical processes in the cerebral cortex. Overall, this reflex plays an important role not only in diagnosis, but also in the scientific evaluation of various mental and behavioral disorders, as well as other common neuropsychiatric diseases.

To summarize, cortical pupillary response correction is an important test in neurological practice and medical research. It is important to evaluate a number of factors, including age, eye color, and general light levels, to obtain an accurate assessment of this reflex. Klee
