somewhat greater in the expused group in 1964
than in the unexposed comparison popuiation.
These abnormalities consist of polychromatic
sheen, lenticular opacities of all degrees, and cataracts. The polychromatic sheen was noted as the
earliest lens change and varied from a few fine
granules in the earlier cases to large granular
plaques in the more advanced cases. These plaques
were situated on the pusterior lens capsule in the
zene of specular reflection. The ecarltest cases
showed yeilowish granules which tn some cases
appeared slightly darker with a “beaten bras”
color. As the granules coalesce into a plaque,
greenish and bluish hues appear - hence the name
pulychromatic sheen.

Whether the polychromatic shecn seen following irradiation has unique and specific characteristics is still a debatable question. Some inves-
ligators contend that umilar appearing changes
can be detected in patients with retinitis pig-
mentosa and the early stages of cataracts which
might be a complication of endogenous ocular ur
systemic disease ur intoxication, Such polychromatic sheens were seenin 21's of the unirradiated
Roneclap group and 26.5" of the exposed group.

incidence of lenticular opacities was also slightly
greater in the exposed eruup (19%) than in the un
exposed group (12°).
Only one child (an &-year-old female) com-
plained of defective meht viston. This was thought
to be due to vitamin A dehcienes, since there were
no pathological changes in the fundus of either eve.
Several vears ago E2 children were encountered
who had ereat dithculty in seeing at naught. Vhes
childres, responded promptly with vitamin A
treatment and dietam changes.
Only two cases were noted with corneal pigmenlation, previoush seen in three cases (14621) This
pigmentation was characterized by a fine, dark.
