| This
is a condition that is characterized clinically by a thinning of the
cornea which leads to ectasia centrally with a cone-like out-pouching of
the cornea. Histologically,
the epithelium and the stroma of the cornea centrally are often
thinned(#21967). There can
also be multiple focal disruptions of epithelial basement membrane and
Bowman's layer anteriorly (#21968). In
addition, Descemet's membrane may rupture in this condition resulting in
acute corneal edema or hydrops.
