What does ectropion refer to?

• A. Eversion of the eyelid
• B. Inversion of the eyelid
• C. Radial deviation of the wrist
• D. Ulnar deviation of the wrist

Answer: (A)

Ectropion specifically refers to the condition in which the eyelid is turned outward or everted. This can result in exposure of the inner eyelid and can lead to various symptoms, including dryness and irritation due to the inability of the eyelid to properly cover the eye. The eversion of the eyelid can occur due to aging, scarring, or various medical conditions. Understanding ectropion is critical in ophthalmology and dermatology, as it directly affects the eye's health and the overall comfort of the patient.

The other options, while related to anatomical conditions or movements, do not pertain to ectropion. Inversion of the eyelid would refer to a different condition known as entropion, where the eyelid folds inward. Meanwhile, radial and ulnar deviation of the wrist are terms related to wrist movements rather than eyelid conditions, further emphasizing the specificity of the term ectropion to eversion of the eyelid.
