Hertel exophthalmometers take a measurement from the lateral orbital rim to the corneal apex. If a patient presents with an orbital fracture or after lateral orbitotomy, the use of a Hertel exophthalmometer may be complicated because the lateral orbital rim serves as a reference point for this instrument.
After the First World War, Hertel moved to Berlin before leaving for the University of Leipzig in 1920, where he remained until his retirement in 1935. Hertel invented the Hertel exophthalmometer, a method of measuring eye displacement. With his colleague, Jakob Stilling, he developed the Stilling-Hertel test for colour vision deficiency.
The hands and feet of people with ectrodactyly are often described as "claw-like" and may include only the thumb and one finger (usually either the little finger, ring finger, or a syndactyly of the two) with similar abnormalities of the feet. [7] People with oligodactyly often have full use of the remaining digits and adapt well to their ...

Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit.Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor).
The digit or finger is an ancient and obsolete non-SI unit of measurement of length. It was originally based on the breadth of a human finger. [1] It was a fundamental unit of length in the Ancient Egyptian, Mesopotamian, Hebrew, Ancient Greek and Roman systems of measurement. In astronomy a digit is one twelfth of the diameter of the sun or ...
Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi. [ 1 ] [ 2 ] This commonly results from weakness of some of the ulnar nerve innervated intrinsic hand muscles -in particular the palmar interosseous muscle to the little finger ...
One then returns to the little finger knuckle (now August) and continues for the remaining months. One variant of this approach differs after reaching the index finger knuckle (July): instead of wrapping around back to the little finger, some people reverse direction and continue from the index finger knuckle (counting it for both July and ...
