meibomian glands
deep face of eyelid, lubricate eyes
blepharitis
inflammation of the eyelid
cherry eye
prolapsed third eyelid, bulldogs predisposed with increased laxity of connective tissue anchor
what are the most common eyelid neoplasias in dogs, cattle, and cats
meibomian gland adenoma, SCC in both cattle and cats
conjunctiva
mucous membranes that line the front of the eyes and inside the eyelids
layers of the cornea from superficial to deep
non-pigmented epithelium, stroma, descemet’s membrane, single layer of endothelium
exophthalmos
protrusion of the eye
ciliary body
makes aqueous humor
choroid
between sclera and retina
three possible infectious causes of corneal edema

synechiae
fibrous adhesion of the iris to either the lense
iris bombe
bilateral posterior synechiae
phthisis bulbi
non-functional shrunken disorganized globe
goniodysgenesis
failure of remodeling of the filtration angle, primary glaucoma
iridociliary tumor
arise from neuroectoderm, more common in dogs
most common lens response to injury
cataract
where does the blood supply for the retina come from
retinal AND choroidal vessels
hypertensive retinopathy
secondary to chronic renal disease, endocrine diseases, and cardiovascular disease from systemic hypertension
three morphologic changes associated with glaucoma
corneal stretching, buphthalmos (increase in size), and “cupping atrophy”
coloboma
defect in closure of the optic fissure, prevents formation of choroid and sclera

aspergillus spp.
equine recurrent uveitis
most common cause of glaucoma, phthisis bulbi from lepto
infectious bovine keratoconjunctivitis
moraxella bovis
bovine malignant catarrhal fever
