Which of the following is a common symptom of Turner's syndrome?

Turner's syndrome is a genetic condition that affects females and is characterized by the absence of all or part of a second sex chromosome. One of the hallmark physical features associated with Turner's syndrome is the webbing of the neck, referred to clinically as "cystic hygroma," which may appear as a web-like structure at the back of the neck. This physical characteristic arises due to the abnormal development of lymphatic vessels during fetal development.

The presence of webbing is not only a common symptom but serves as an important clinical clue in diagnosing Turner's syndrome. Patients may also exhibit other physical features, such as a low hairline, broad chest, and shorter stature. These elements collectively help healthcare providers recognize the syndrome when evaluating a patient.

The other symptoms listed—heightened vision, glaucoma, and amblyopia—do not specifically correlate with Turner's syndrome. While some individuals with Turner's syndrome may experience visual or eye issues, they are not defining characteristics of the condition, making webbing of the neck the most relevant choice in this context.
