Both eyes were myopic, but no other cause could be assigned.

Another similar case is cited by Hirshberg, and the authors have seen similar cases.
Thornton of Margate records the case of a lady in whom the hair of the left eyebrow and eyelashes began to turn white after a fortnight of sudden grief, and within a week all the hair of these regions was quite white and remained so.

No other part was affected nor was there any other symptom.

After a traumatic ophthalmitis of the left and sympathetic inflammation of the right eye in a boy of nine, Schenck observed that a group of cilia of the right upper lid and nearly all the lashes of the upper lid of the left eye, which had been enucleated, turned silvery-white in a short time.

Ludwig has known the eyelashes to become white after small-pox.
