| Open
angle glaucoma can occur secondary to any process which leads to invasion
of the angle structures by abnormal cells.
One entity that can do this is a malignant melanoma at the base of
the iris or at the ciliary body. The
melanoma cells may then invade the trabecular meshwork tissue leading to
secondary glaucoma. Histopathologically,
this is characterized by variably pigmented melanoma cells which are seen
to directly invade the trabecular meshwork and other structures of the
anterior chamber angle (#21981).
