Flashcards in Cornea Anatomy and Disease Recognition Deck (10):

White corneal opacity and is a sign of active inflammation. Signs are pain and usually signifies an ocular emergency.

WBC infiltration


Corneal Scarring, results from stromal collagen contracture and appears as a dull, wispy white results form past keratitis.

Corneal fibrosis


________ often involves lipid and appears glittery/shiny. _________ often involves calcium and appears gritty or chalky. (Both involving the Cornea )

Corneal Dystrophy and Degeneration


devitalized portion of the corneal stroma that pigments amber to black in felines. The cause of the pigment is unknown, though this condition often forms following chronic or recurrent corneal ulceration.

Feline corneal Sequestrum


cellular adhesions to the endothelium and are pathognomic for uveitis. You will see tiny dots from the mid-portion of the cornea that become larger and denser in the ventral cornea.

Keratic Precipitates


loss of corneal stroma with intact overlying epithelium,. Occurs b/c epithelialziation of a corneal ulcer progresses more rapidly than stromal healing.



There are two common sources of this, Epithelial disruption and endothelial disruption. The only 'blue' opacity.

Corneal edema


vessel pattern occurs in response to superficial disease processes. Tree like appearance, seen crossing the limbus, and can coalesce to form raised granulation tissue.

Superficial corneal neovascularization


vessel pattern in response to deep disease processes.(ulcers, uveitis, and glaucoma). Vessels are straight, not seen crossing limbus, and do not extend as fare across the cornea.

Deep Corneal neovascularization


360 degree deep corneal neovascularization.
