ACCOMMODATION IRIDOPLEGIA Meaning and
Definition
-
Accommodation iridoplegia is a medical term that refers to a condition characterized by the inability to accommodate or adjust the focus of the eyes, as well as a fixed and dilated pupil. Accommodation is the process by which the lens of the eye changes its shape in order to focus on objects at different distances. It is primarily controlled by the ciliary muscle that surrounds the lens. Iridoplegia refers to the paralysis or dysfunction of the muscles that control the constriction and dilation of the pupil, which helps regulate the amount of light that enters the eye.
Accommodation iridoplegia usually occurs as a result of damage or dysfunction of the nerves that control these eye muscles. Conditions that can cause accommodation iridoplegia include certain neurological disorders, such as diabetes, multiple sclerosis, or trauma to the head or eye. The inability to adjust focus combined with a fixed dilation of the pupil can lead to difficulties in seeing objects at various distances and in adapting to changes in lighting conditions.
Common symptoms of accommodation iridoplegia can include blurred vision, sensitivity to light, and impaired depth perception. Treatment options typically focus on managing the underlying cause of the condition, if possible, and may involve the use of corrective lenses to aid with focusing and wearing sunglasses to mitigate light sensitivity. In more severe cases, surgical interventions, such as iris reconstruction or lens replacement, may be required to restore visual function.

Etymology of ACCOMMODATION IRIDOPLEGIA
The term "accommodation iridoplegia" is a combination of three separate components:
1. Accommodation: The word "accommodation" in this context refers to the ability of the eye to adjust its focus in order to see objects at different distances clearly. It comes from the Latin word "accommodare", which means "to fit" or "to adjust".
2. Iridoplegia: "Iridoplegia" is a medical term that refers to paralysis or immobility of the iris, which is the colored part of the eye. It is derived from the Greek words "iris" (meaning "rainbow") and "plegein" (meaning "to strike" or "hit"). The term indicates the inability of the iris to properly respond to changes in light or focus.
