What is the technical term for constricted pupils?

The technical term for constricted pupils is miosis. This term is derived from the Greek word "myein," which means "to close." Miosis typically occurs in response to certain stimuli, such as exposure to bright light, the effects of specific drugs, or certain medical conditions. In the context of drug recognition and examination, recognizing miosis can be crucial for identifying the potential influence of opioids and some other substances that can cause constriction of the pupils.

Mydriasis, on the other hand, refers to the dilation of pupils, while anisocoria describes a condition where the size of the pupils is unequal. Presbyopia is an age-related condition affecting the eye’s ability to focus on nearby objects and does not relate to pupil size. Understanding these terms is key for drug recognition experts when assessing a subject’s condition.
