PARALYTIC MYDRIASIS Meaning and
Definition
-
Paralytic mydriasis refers to a medical condition characterized by the abnormal dilation of the pupil, resulting from paralysis or dysfunction of the muscles that control pupil constriction. The term "paralytic" suggests that the condition is caused by an impairment or lack of muscle function, while "mydriasis" specifically refers to the excessive dilation of the pupil.
There are various potential causes of paralytic mydriasis, including traumatic injury to the eye or head, certain neurological conditions, medication side effects, or underlying diseases affecting the nerve pathways that control the pupil. The dysfunction could occur in the muscles within the iris, which regulate pupil size, or in the nerves that transmit signals to these muscles.
Symptoms of paralytic mydriasis typically include a significantly widened pupil that does not respond to changes in light intensity. Depending on the underlying cause, other symptoms such as blurry vision, eye pain, double vision, or drooping eyelid may be present. The condition can occur in one or both eyes.
The treatment of paralytic mydriasis depends on addressing the underlying cause. For instance, if the condition is caused by medication, adjusting the dosage or switching to an alternative drug might be necessary. In cases where there is a neurological issue, appropriate neurological treatment may be recommended. In some instances, the effects of paralytic mydriasis may be temporary and resolve once the underlying cause is treated, while in other cases, the dilation may be permanent.

Etymology of PARALYTIC MYDRIASIS
