| Rupture
of the lens capsule, either traumatically or iatrogenically, may lead to
loss of the lens nucleus and much of the anterior and posterior cortex.
Remnant peripheral or equatorial lens cortex, as well as
proliferating lens epithelial cells in tahe periphery, form a Soemmering's
ring. This is characterized
by a peripheral donut or ring-shaped configuration when viewd
grossly(#22204). When viewed
grossly in cross-section, the Soemmering's ring appears to have a dumbbell
configuration (#22205). Histopathologically,
a Soemmering's ring cataract is characterized by proliferating lens
epithelial cells in the periphery or equatorial region of the lens, as
well as remnant, trapped degenerated lens cortex (#22207).
(#22161) is
another view of a Soemmering's Ring cataract.
