Persistent Miosis is a medical condition characterized by the persistent constriction of the pupil of the eye, which can lead to a variety of symptoms such as blurry vision, sensitivity to light, and headaches. Antonyms for Persistent Miosis include dilated pupils, which refers to the widening of the pupil, and Mydriasis, which is a medical term used to describe excessive dilation of the pupil. Dilated pupils can cause sensitivity to light, but they allow more light to enter the eye, resulting in improved vision in dimly lit environments. Mydriasis, on the other hand, can be caused by the use of certain medications or drugs and may lead to blurred vision and light sensitivity.
