Answer:
The mallet unit for a foveal suppression test is typically held at a specific distance from the patient's eye. This distance is usually about 33 centimeters (approximately 13 inches) from the patient's eye. Holding the mallet unit at this distance helps assess the suppression of the fovea, the central part of the retina responsible for sharp vision. The test is often used in optometry and ophthalmology to diagnose certain visual disorders.
