Tumors of The Eyeball.

Tumors of The Eyeball.

A variety of tumors attack the eyeball dermoid, papillary, fatty, cystic, and melanotic but perhaps the most frequent in the horse is encephaloid cancer. This may grow in or on the globe, the haw, the eyelid, or the bones of the orbit, and can be remedied, if at all, only by early and thorough excision. It may be distinguished from the less dangerous tumors by its softness, friability, and great vascularity, bleeding on the slightest touch, as well as by its anatomical structure.
