Mydriasis is frequently induced by drugs for certain ophthalmic examinations and procedures, particularly those requiring visual access to the retina. Fixed, unilateral mydriasis could be a symptom of raised intracranial pressure. The opposite, constriction of the pupil, is referred to as miosis. Both mydriasis and miosis can be physiological.
List of medical symptoms. Medical symptoms refer to the manifestations or indications of a disease or condition, perceived and complained about by the patient. [1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals.
Multisystemic smooth muscle dysfunction syndrome (MSMDS) is a genetic disorder caused by R179 missense mutations in the ACTA2 gene. Initially described as a case report in 1999, [2] it was characterized in 2010 [3] as a syndrome of congenital mydriasis, patent ductus arteriosus, and aneurysmal arterial disease—in particular aortic and thoracic aneurysms.
The symptoms of an opiate toxidrome include the classic triad of coma, pinpoint pupils and respiratory depression [3] as well as altered mental states, shock, pulmonary edema and unresponsiveness. Complications include bradycardia , hypotension and hypothermia .

A diagnosis should at a minimum include measurements of blood pressure and heart rate while lying flat and after at least three minutes of standing. The best way to make a diagnosis includes a range of testing, notably an autonomic reflex screen, tilt table test , and testing of the sudomotor response ( ESC , QSART or thermoregulatory sweat test).
As a result of cholinergic crisis, the muscles stop responding to the high synaptic levels of acetylcholine, leading to flaccid paralysis, respiratory failure, and other signs and symptoms reminiscent of organophosphate poisoning. Other symptoms include increased sweating, salivation, bronchial secretions along with miosis (constricted pupils).
Horner's syndrome, also known as oculosympathetic paresis, [1] is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.
