Blown pupil is an informal medical term used by physicians and nurses to refer to sudden pupillary dilation and loss of ability to constrict in response to light. It is an important clinical sign in physical diagnosis, especially in emergency department or intensive care unit patients, where it can signal a stroke, impending brain herniation, or other brain catastrophe.
