Mydriasis
When an individual’s pupils enlarge in an unusual way, it is called mydriasis. Mydriasis might be caused by an injury, psychological factors, or when an individual takes particular drugs or medications.
Mydriasis may affect one or both pupils at a time. When mydriasis affects only one eye then it is known as anisocoria.
Studies estimated that 1 out of 5 people are born with somewhat different sizes of pupils, and their eyes react differently when there are any changes in the light. This condition is known as physiologic, simple, or essential anisocoria.
The major problem of mydriasis is dilated pupils that do not respond when light gets changed and the size of pupils do not get bigger or smaller.
When the pupils get enlarged, the eyes become more sensitive to light. This can cause blurry vision, as well as, in some cases, a general feeling of deflation around the forehead and eyes.
Sometimes people may also experience headaches, dizziness, eye irritation, and feel trouble in sleeping along with mydriasis.
