Scleromalacia perforans
is a painless form of necrotizing scleritis that has no
obvious inflammatory signs. It is charaterized by a progressive thinning
of the sclera. The eye develops a bluish color in the
affected regions as uveal pigment begins to show through
the thinned sclera.
Despite its name,
scleromalacia perforans rarely results in perforation.
Gross bulging of the ocular surface or rupture secondary
to trauma can require tectonic repair with a scleral
graft.
