Most ocular disease whether it be deep disease like uveitis, or superficial disease like allergic conjunctivitis will manifest clinical signs involving the conjunctiva.
“Seeing” how it reacts is vital to understanding how to treat conjunctivitis.
Learn the Anatomy
The conjunctiva is connective tissue divided into bulbar (globe) , palpebral (eyelid) and fornix regions. It separates the periorbital tissue from the Tenon’s capsule. Palpebral conjunctiva is NOT freely moveable, whereas the bulbar conjunctiva is. The superficial layer plays host to adenoid follicles and glandular structures whilst the deeper layer contains branches of the ophthalmic and maxillary nerves and larger blood vessels.
Normal flora and normal cytology.
70-90% of dogs can have bacteria cultured. Staphlococcal, Bacillus and Corynebacteria predominate. 8% gram negative bacteria, anaerobes rarely isolated. Normal cytology sheets of non-keratinised squamous epithelium, with lots of cytoplasm.
