ABSTRACT
The cause of the anomalous head posture (AHP) has been mainly assigned to ocular, orthopedic, and neurologic causes. The AHP can take the form of head tilt, face turn, chin up, chin down, or combined, depending on the specific etiology. However, there are many variations, and the type of the head posture cannot reliably predict the underlying cause. Ocular AHP is usually an attempt to improve visual acuity or binocularity. Since the etiology is not always obvious, we stress that these patients must be carefully evaluated by ophthalmologists. Our effort here is to offer the neurologist a thorough insight in the specific head posture pattern primarily related to visual disorders.

Two siblings born to a mother with Wilson's disease, who was taking D-penicillamine, developed transient goitrous hypothyroidism. A prospective evaluation of 5 patients with Wilson's disease taking and not taking D-penicillamine for as long as 9.5 years showed subclinical hypothyroidism. D-penicillamine probably inhibited thyroperoxidase activity in utero in healthy infants and during childhood in patients with Wilson's disease.
