Pupillary Reaction Friendly

Friendly pupillary reaction: what is it and why is it important?

Pupillary response is an important indicator of the normal functioning of the visual system. It allows you to assess the functional state of the visual pathways and determine the presence of pathological changes in the eyes. One type of pupillary reaction is the congenial pupillary reaction.

Friendly pupillary reaction is a constriction of the pupil of one eye when a light stimulus is applied to the other eye. This narrowing is a reflex response that occurs due to connections between visual pathways in the brain. When light hits one eye, it stimulates the optic nerve and is transmitted to the brain. The brain then activates special nerve pathways that transmit a signal to the other eye, causing its pupil to constrict.

The friendly pupillary reaction is of great importance in neurology and ophthalmology. It allows you to evaluate the functioning of the visual pathways and identify the presence of pathologies. For example, when visual pathways such as the optic nerve or visual cortex are damaged, the pupillary concomitant response may be impaired. Also, a change in pupillary response may indicate various eye diseases, such as glaucoma or cataracts.

To conduct a study of the pupillary response, special devices are used - pupil meters. They allow you to evaluate pupil size under various conditions and determine the presence of changes in pupillary response. This helps to diagnose diseases of the eyes and visual pathways in the early stages and prescribe effective treatment.

In conclusion, pupillary response is an important indicator of the normal functioning of the visual system. Its change may indicate various diseases of the eyes and visual pathways. Therefore, regular measurement of pupillary response is an important component of the prevention of diseases of the eyes and visual pathways.



Pupillary cooperative response is a physiological mechanism that allows each eye in a pair to work together and synchronize with each other. It occurs due to the interaction between the optic nerves that control the pupils of the eyes.

When a person looks at bright light, the optic nerves begin transmitting signals about the brightness of the light to the brain, which then sends a signal to the eye to cause the pupil to dilate or constrict. This process occurs in both eyes simultaneously. If one eye receives less light than the other, the pupil of that eye contracts faster, which helps equalize the brightness between the eyes and maintain good visibility in both eyes. As a result of pupillary
