In it we have bone, periosteum, muscular tissue, fat, fibrous and connective tissue, glands and mucous membrane, and in the capsule of Tenon a serous cavity lined with a serous membrane. There is also the optic nerve and a liberal supply of blood vessels. Among the malignant tumors we find carcinoma, sarcoma, myo-sarcoma, and from the internal ocular tunics, melano-sarcoma and glioma.
