Pupillary Response

Pupillary response is a general name for certain types of pupillary responses that occur in response to various stimuli such as light, accommodation, and convergence. These reactions are part of a complex system that allows us to perceive and respond to the world around us.

Pupillary reaction to light is one of the most studied and known forms of pupillary reaction. When we see bright light, our pupil dilates to allow more light into the eye. This occurs due to the contraction of the muscles that surround the pupil. Dilating the pupil allows more light to pass through, which helps us see better.

The accommodative reaction is a reaction that occurs when it is necessary to focus the gaze on a nearby object. At the same time, our pupil narrows to focus the image on the retina. The constriction of the pupil occurs due to the contraction of the ciliary muscle, which is located at the back of the eye.

Convergence response is another form of pupillary response that occurs when trying to focus on an object at a distance. With convergence, our eyes move closer together to focus better. Convergence also helps us see objects at great distances.

All of these responses are important components of our visual system and help us adapt to different lighting and focusing conditions. Pupillary responses can also be affected by various diseases such as glaucoma or cataracts.

**Pupillary reaction** is a general name for several types of pupillary reflexes that directly characterize the speed or uniformity of the constriction of the pupil when it is exposed to light irritability or mechanical irritation by bringing the eyeballs together. The main types of pupillary reaction, thanks to the ability to assess their functional state of the eye as a whole, due to the variety of manifestations, can become a convenient tool for objective monitoring of the technical functioning of artificial means and optical devices. Most types of pupillary reactions are described as follows: The pupil "responds quickly" to a light stimulus (pulse, flash, etc.) if the reaction time is less than 35 milliseconds or about 0.035 seconds Synonymous reactions are divided into the following categories: Photoreaction Reverse photoreaction, sometimes called solar Hypoconversion Hyperexia Trembling of the eyeball
