Morgagnian Cataract

Up

A long-standing or very mature cataract may undergo liquefaction of the lens cortex.  The dark brown, mature nucleus then sinks inferiorly in the fluid filled capsular sac due to the forces of gravity.  This may be noted clinically with the brown nucleus seen to lie inferiorly withing the capsular sac (#22201).  Examination of a Morgagnian cataract grossly reveals a very hard, brunescent appearing nucleus with a markedly liquified cortex and loosely wrinkled capsular bag(#22202).

 

(#22227, #22245) are other views of Morgagnian type cataracts.
