Iridoplegia is a medical condition characterized by the paralysis of the sphincter muscles of the iris, leading to pupil dilation and often a lack of responsiveness to light. The spelling of this word is "eye-ree-doh-plee-jee-uh", with the stress on the third syllable. The "i" in the first syllable is pronounced as "eye", while the "o" in the third syllable is pronounced as "oh". The phonetic transcription of this word is /aɪrɪdəʊpliːdʒə/. Iridoplegia can occur due to various neurological or ophthalmological conditions, including strokes, tumors, or injury.
Iridoplegia refers to a medical condition characterized by the paralysis of the muscles of the iris, which is the colored part of the eye that surrounds the pupil. The condition can result in the inability of the iris to constrict or dilate properly, leading to problems with the regulation of the amount of light entering the eye.
Individuals with iridoplegia may experience a range of symptoms, including an abnormal response to changes in light, reduced vision acuity, and a lack of control over the size of the pupil. The condition can affect one or both eyes and may be accompanied by other eye-related issues, such as decreased accommodation or difficulty focusing.
Iridoplegia can be caused by various factors, including nerve damage, trauma to the eye, inflammation of the iris, certain medications, or underlying medical conditions such as diabetes or multiple sclerosis. The condition may also be associated with certain genetic disorders or occur as a result of aging.
Treatment for iridoplegia typically focuses on managing the underlying cause of the condition. This may involve medication, surgery, or other interventions to address any nerve or muscle damage. Additionally, individuals with iridoplegia may need to take measures to protect their eyes from excessive light or wear special lenses to improve visual function and reduce discomfort.
Overall, iridoplegia is a medical condition involving paralysis of the iris muscles, which can result in impaired control of pupil size and light regulation within the eye.
Paralysis of the sphincter of the iris.

The word "iridoplegia" is derived from a combination of two roots: "iris" and "plegia".
1. "Iris" originates from the Greek word "eirēnē", which means "rainbow". The iris is the colored part of the eye that surrounds the pupil and gives it its unique hue.
2. "Plegia" stems from the Greek word "plēgē", meaning "paralysis" or "loss of function".
When combined, "iridoplegia" refers to the paralysis or dysfunction of the iris muscles, resulting in a loss of its ability to control the size of the pupil.
