Fritsch and
Valisneri have seen this anomaly and there are modern references
to it. Wordsworth presented to the Medical Society of London six
members of one family, all of whom had congenital displacement of
the crystalline lens outward and upward. The family consisted of
a woman of fifty, two sons, thirty-five and thirty-seven, and
three grandchildren--a girl of ten and boys of five and seven.
The irides were tremulous.
Clark reports a case of congenital dislocation of both
crystalline lenses. The lenses moved freely through the pupil
into the anterior chambers. The condition remained unchanged for
four years, when glaucoma supervened.
Differences in Color of the Two Eyes.--It is not uncommon to see
people with different colored eyes. Anastasius I had one black
eye and the other blue, from whence he derived his name "Dicore,"
by which this Emperor of the Orient was generally known. Two
distinct colors have been seen in an iris. Berry gives a colored
illustration of such a case.
The varieties of strabismus are so common that they will be
passed without mention. Kuhn presents an exhaustive analysis of
73 cases of congenital defects of the movements of the eyes,
considered clinically and didactically.
