SPASTIC MIOSIS Meaning and
Definition
-
Spastic miosis refers to a medical condition characterized by abnormal constriction or narrowing of the pupil of the eye due to muscle spasms in the iris. The pupil is the small black hole in the center of the eye responsible for controlling the amount of light entering the eye. Normally, the pupil adjusts its size accordingly to regulate the flow of light, but in cases of spastic miosis, the muscles in the iris involuntarily contract, causing the pupil to excessively shrink in size.
Spastic miosis can be caused by various factors such as neurological disorders, medications, or trauma to the eye. Neurological conditions that can lead to spastic miosis include conditions affecting the brain or spinal cord, such as multiple sclerosis or cerebral palsy. Certain medications, like opioids or other drugs that affect the nervous system, can also cause abnormal constriction of the pupil.
Symptoms of spastic miosis may include reduced vision in bright light, eye strain, difficulty focusing, and increased sensitivity to light (photophobia). Diagnosis is typically made through a comprehensive eye examination conducted by an ophthalmologist or optometrist.
Treatment for spastic miosis depends on the underlying cause. Managing the underlying condition or discontinuing medication responsible for the symptoms may alleviate the problem. In some cases, eye drops such as dilating agents may be prescribed to alleviate the pupil constriction and improve vision. It is important to seek prompt medical attention if experiencing symptoms of spastic miosis, as it may indicate an underlying health issue that needs to be addressed.

Etymology of SPASTIC MIOSIS
The term "spastic miosis" refers to a condition characterized by excessive constriction of the pupil due to increased muscle tone in the iris sphincter muscle. However, it is important to note that "spastic miosis" is not a commonly used medical term. The correct medical term for this condition is "spasticity of the iris", and it is often associated with neurological disorders or damage to the nerves controlling the pupil's size.
As for the etymology of the words involved:
1. Spastic: The word "spastic" originated from the Greek word "spastikos", meaning "drawing, pulling". It was first used in English in the late 18th century to describe involuntary muscular spasms or rigidity.
2. Miosis: The word "miosis" comes from the Greek word "meiosis", meaning "a lessening or reduction".
