Causes Of Eye Miosis

Age Or Genetics

Age or genetics are perhaps the most common causes of vision-related problems. As the body ages, nerve signaling weakens and slows down, and individuals lose a lot of their muscle control. However, this can also occur prematurely as a result of genetic inheritance. Some individuals who suffer from eye miosis were born without the proper muscles to control the pupils; these muscles may also be present but improperly formed. This condition is called congenital miosis, or 'microcoria,' and is directly passed down from parent to child. It can happen in one or both of the eyes, causing pressure on the eyeballs and negatively impacting the pupils' ability to react to light appropriately.

Side Effect Of Medication

Prescription medication side effects are vast and varied. However, pinpointed pupils are one of, if not the, most common side effect of many of these drugs. Apart from narcotics, prescription medications that treat anxiety, seizures, and muscle spasms are known to shrink pupil sizes and make the eyes more sensitive to light. Diazepam, a common relaxant, is one such example. Even over-the-counter, everyday antihistamines can produce this effect. For a patient whose vision is suffering due to miosis, doctors will first examine the list of medications they take regularly and look for effective alternatives.
