On the right side, in front
of the external half of the sclerotic, was observed a semilunar
fold with the concavity inward, and which projected much more
when the lower lid was depressed. When the eyelid rolled inward
the fold rolled with the globe, but never reached so far as the
circumference of the cornea and did not interfere with vision.
Total absence of both irides has been seen in a man of eighteen.
Dixon reports a case of total aniridia with excellent sight in a
woman of thirty-seven. In Guy's Hospital there was seen a case of
complete congenital absence of the iris. Hentzschel speaks of a
man with congenital absence of the iris who had five children,
three of whom exhibited the same anomaly while the others were
normal. Benson, Burnett, Demaux, Lawson, Morison, Reuling,
Samelson, and others also report congenital deficiency of the
irides in both eyes.
Jeaffreson describes a female of thirty, living in India, who was
affected with complete ossification of the iris. It was immovable
and quite beautiful when seen through the transparent cornea; the
sight was only slightly impaired. No cause was traceable.
Multiple Pupils.--More than one pupil in the eye has often been
noticed, and as many as six have been seen.
