EXTERNAL SQUINT Meaning and
Definition
-
External squint, also known as exotropia, refers to an ophthalmological condition characterized by the deviation of one or both eyes outward, away from the nose, when focusing on an object. In this eye misalignment disorder, the affected eye(s) appear to turn away or diverge from the center of the face, resulting in a noticeable outward deviation.
External squint is commonly caused by a muscular imbalance or weakness in the muscles responsible for eye movement and coordination. Individuals with this condition often experience difficulties with binocular vision, depth perception, and may have limited ability to fixate on objects. The exact cause of exotropia can vary, including factors such as hereditary factors, nerve damage, or prior eye trauma.
Treatment options for external squint primarily aim at realigning the eyes to restore binocular vision and improve visual acuity. These can include corrective lenses, prism glasses, vision therapy, and, in some cases, surgery. Early intervention is often recommended to prevent further complications and ensure the best possible visual outcomes.
Overall, external squint or exotropia is an eye misalignment condition where one or both eyes deviate outward, away from the center of the face. Understanding the causes, symptoms, and available treatment options is essential for effectively managing this condition and preserving optimal visual function.

Etymology of EXTERNAL SQUINT
The term "external squint" is a medical condition related to the misalignment of the eyes, also known as strabismus. The etymology of the word "external" is from the Latin word "externus", meaning "outer" or "pertaining to the outside". In the context of strabismus, "external" refers to the deviation of the eyes outwardly, away from the midline.
The word "squint" comes from the Old English verb "scīnan", which means "to shine" or "to squint". Over time, "squint" evolved to refer to the act of looking with one eye partially closed or at an angle. In the case of strabismus, it describes the misalignment of the eyes, where one eye focuses on an object while the other eye deviates inward or outward.
