GOULDS SIGN Meaning and
Definition
-
Gould's sign refers to a medical symptom or diagnostic finding originally described by American physician, George M. Gould. This sign specifically pertains to the field of ophthalmology and neurology. It is characterized by the observed constriction of the pupil when the patient's eyelids are forcibly closed or squeezed together. This phenomenon is also known as the eyelid closure pupillary reaction.
Normally, when the eyelids are closed or squeezed, the pupil dilates. However, in cases displaying Gould's sign, the opposite occurs, and the pupil constricts or becomes smaller. This abnormal response is believed to be indicative of an underlying neurological condition, usually involving damage to the sympathetic nervous system, which controls pupil dilation among other functions.
The manifestation of Gould's sign can assist healthcare professionals in diagnosing a range of medical conditions, such as Horner's syndrome, Adie's pupil, Argyll Robertson pupil, and certain brainstem lesions. It can also aid in determining the location and extent of the neurological damage. While Gould's sign alone may not provide a definitive diagnosis, it can serve as a valuable clue that prompts further investigation and additional diagnostic tests.
In summary, Gould's sign is a clinical finding characterized by the constriction of the pupil during eyelid closure or compression, contrary to the normal physiological response. It is typically associated with neurological disorders and can assist healthcare practitioners in identifying and localizing these conditions.
