Conjunctiva

 

the connective membrane of the eye.

The conjunctiva is the transparent mucous membrane that covers the posterior surface of the lids and the anterior surface of the eyeball as far as the cornea; therefore it is distinguished, respectively, as palpebral conjunctiva or ocular (scleral) conjunctiva. The tunica conjunctiva consists of an epithelial layer and a connective-tissue base. It contains glands that perform the function of supplementary lacrimal glands. The conjunctiva is rich in blood and lymph vessels and sensory nerves.

Hemangiosarcomas are tumors originated from vascular endothelium, and in the eye, they are generally manifested by the bulbar conjunctiva. A few case series of these neoplasms are reported in cats and dogs (MULTARI et al., 2002; LIAPIS & GENOVESE, 2004; HARTLEY et al., 2006).
