Which test is used to assess tear secretion in Familial Dysautonomia?

• A. CT scan
• B. Schirmer test
• C. Blood test
• D. Ultrasound

Answer: (B)

The Schirmer test is specifically designed to evaluate tear production and secretion. In the context of Familial Dysautonomia, which is a genetic disorder affecting the autonomic nervous system, patients often experience reduced tear production due to autonomic dysfunction. The Schirmer test involves placing a small strip of filter paper in the lower eyelid and measuring the amount of moisture absorbed over a set period of time. A lower than normal measurement indicates decreased tear secretion, which is a common symptom in individuals with this condition. This targeted approach makes the Schirmer test the most appropriate choice for assessing tear production in patients with Familial Dysautonomia, highlighting the nature of how this condition affects autonomic functions related to tear secretion. The other options, such as imaging studies or blood tests, do not provide relevant information about tear production or autonomic function in this specific context.
