![]() Horner’s syndrome that causes asymmetrical facial appearance has been associated with a wide range of medical conditions including brain tumors and multiple sclerosis. The symptoms are usually noticed on one side of the face and manifest in the form of a constricted pupil, droopy eyelid, and enophthalmos (sunken eyeball). This condition is characterized by damage to the nerves of the sympathetic nervous system. Poorly controlled high blood pressure is one of the main risk factors in the development of brain-stem disorders. Experts opine that dysfunction of the brainstem, often due to hemorrhage, can constrict the pupils. In this condition, a blood vessel supplying blood to the brain is ruptured, which can compromise blood flow, and moreover, cause bleeding. Hemorrhagic stroke that cuts off blood supply to a specific part of the brain, particularly the brainstem can lead to constricted pupils. It is observed that the prolonged inflammation of iris exerts excessive pressure on the pupil, which can make it significantly smaller in size. Many times, iris inflammation accompanies medical conditions like rheumatoid arthritis and infectious diseases that include tuberculosis, toxoplasmosis, and syphilis. An inflamed iris can be caused due to an eye injury or a herpes zoster infection. So the nerves of the eyes may also get affected by the regular use of these drugs, which may eventually cause reduction in pupil size.Įye problems that cause inflammation of the iris (colored part of the eye surrounding the pupil) can lead to abnormal constriction of pupils. When a person ingests illicit or prescription drugs, they may experience a range of behavioral, mental, and physical side effects. In some cases, small pupils may indicate a drug overdose or other drug interaction. These drugs essentially depress the central nervous system, which controls the visual system of the body. Pinpoint pupil size may occur with the use of certain drugs such as heroin, morphine, fentanyl and other opioids. Taking these drugs may also cause reduction in pupil size. These drugs may also help relieve symptoms of sleeping problems. BenzodiazepinesĪlso referred to as tranquilizers, benzodiazepines provide a calming effect and are recommended in the management of anxiety and panic attacks. In fact, small or pinpoint pupils, blurred vision, runny nose, headache, and muscle weakness are the most common symptoms of OP poisoning. Upon exposure, the insecticide stimulates the parasympathetic system, which can make the pupils constricted. Oraganophosphates (OP) that are commonly used in agriculture as insecticides can also affect the eyes and cause pinpoint pupils. However, the usage of these miotic drugs can cause the pupil to become small. Miotics that are available in the form of drops help in relieving IOP by promoting the drainage of eye fluids, which works in managing the condition. ![]() This optic nerve damage has often been linked to increased intraocular pressure (IOP)―fluid pressure inside the eye―as the eyes are unable to get rid of excess fluid. These drugs are often recommended to treat glaucoma, a condition that is marked by malfunctioning of the optic nerve. Drugs that make pupils constrict are often referred to as miotics.
