What is the medical term used to describe pupils smaller than 2mm?
Explanation & Rationale
A. Mydriasis refers to dilation of the pupils, where the pupils become larger than normal. This can occur due to low light, sympathetic stimulation, certain medications, or neurological conditions. Since the question describes small pupils, mydriasis is incorrect. B. Accommodation is the process by which the eyes adjust focus for near or distant objects. It involves changes in lens shape and pupil size, but accommodation itself is not a term for abnormally small pupils, so this option is incorrect. C. Miosis is the medical term for constriction of the pupils, typically smaller than 2 mm in diameter. Causes can include opioid use, exposure to bright light, or certain neurological conditions. This directly matches the description in the question, making it the correct answer. D. Conjunctivitis is inflammation of the conjunctiva (the membrane covering the front of the eye and inner eyelids), often caused by infection, allergies, or irritants. It affects the eye’s surface but does not describe pupil size, so this option is incorrect.
