Iris shadow: visible in
' Iris Shadow '
Immature Senile cataract.
Logic: When there is any clear cortex between the iris and the opacity (greyish white in immature senile cataract), the shadow of the iris which falls upon the opacity, as light is cast upon the eye is visible through the clear cortex. This is called the 'iris shadow' and is a common sign in immature senile catarct.
