ART.IX.-Ossification of the Choroid | Operating Microscopes

Osseous tissue has often been observed in atrophied eyes. It arises from the disposition of calcareous salts in the cellular tissue of the choroid. Sometimes only a few bone corpuscles are found on the internal surface of the choroid; sometimes there exists a true osseous shell, extending from the optic nerve to the anterior portion of the eyeball, and even to the ciliary body.

This osseous change of the choroid in atrophic eyes may become a source of acute pain, spontaneously or on the eyeball being touched; the risk of a sympathetic inflammation in the other eye then demands the immediate enucleation of the atrophied one.
