Malignant melanocytic neoplasm
Feline corneal sequestrum
Increased superficial stromal necrosis compared to normal corneal epithelial injury. Accumulation of brown pigment from tear film into corneal stroma.
Immune mediated
What is the suspected cause of canine pannus keratitis?
Adaptive cutaneous metaplasia
This is a response to persistent mild irritation and causes keratinization, epithelial hyperplasia, and neovascularization.

Single midline globe, no duplication of structures
Benign
Are melanocytic neoplasms on the limbus benign or malignant?
GSD(s)
What breed is the most common in canine pannus keratitis?
Melanocytoma
Benign melanocytic neoplasm
Thelazia
This parasite can inhabit the conjunctival sac and lacrimal duct, and is transmitted by flies
Conjunctival
Adult cats with FHV-1 usually get what ocular form?
True
True or false? SCC tend to be locally invasive, and if they do metastasize it is not until very late in the disease.
Non pigmented
SCC are common in cattle/horses with ___ ___ eyelids/conjunctiva exposed to sunlight.
Veratarum californicum, 15
What plant can ewes ingest that causes cyclopia/synophthalmia? What day during gestation do they have to ingest it?
Face fly
What is the major way that pink eye is transmitted?
Central
Are feline corneal sequestrums usually central or peripheral?
Infectious bovine keratoconjunctivitis
Pink eye in cattle
Allergic, mechanical, dessication
What are the 3 most common general causes for canine conjunctivitis?
Infectious bovine rhinotracheitis
What does IBR stand for?
IBR
What do you need to differentiate pink eye from in cattle?
Merle
What color gene should you never breed a pair of, because they have multiple congenital ocular abnormalities?
Kitten(s)
FHV-1 causes the worse ocular symptoms, like keratitis and corneal ulceration, mostly in what demographic?
Herefords
What breed of cattle commonly gets SCCs?
Location
What is the big factor in melanocytic neoplasm that determine malignancy?
Nodular granulomatous episcleritis
What does NGE stand for involving the eye?
Benign
Are melanocytic neoplasms on the eyelid benign or malignant?
Synophthalmia
A single midline globe with duplication of structures
Infected
Keratomalacia results from an ___ corneal ulcer
Aspergillus
What kind of fungus is most common in equine mycotic keratitis?
Meibomian adenoma
Most common tumor of the eyelid in dogs
NGE
This results in proliferation of histiocytes, fibroblasts, lymphocytes, and plasma cells.
Fungal hyphae
What are the bright pink structures?
Keratitis, conjunctivitis
What 2 things are you likely to see in a kitten with initial infectino of FHV1?
IBR
What does bovine herpes virus 1 cause?
Conjunctiva
What part of the eye do Habronema usually go?
Persians, Himalayans
What cat breeds are predisposed to feline corneal sequestrums?
Section 2
(50 cards)
Systemic disease
Most cases of uveitits reflect involvement of what?
Expansile, glaucoma
Iridociliary adenomas are ___, causing secondary ___.
Meningioma
This optic nerve tumor is most common in dogs, is usually benign, and metastasis is uncommon.
Leptospira, onchocerca
ERU may be due to a hypersensitivity reaction to what 2 organisms?
Cats
What species get diffuse iris melanomas?
Blastomyces
Most common systemic fungus in dogs
Anterior
ERU is repeated bouts of ___ uveitis increasing in severity
Preiridla fibrovascular membrane
What does PIFM stand for?
Phacolytic
This form of uveitis is due to leakage of lens proteins that are highly antigenic and cauase inflammation, and occurs secondary to cataracts
Cataract
Lenticular opacity
PIFM
This results from anterior uveitis, and causes trabecular occlusion and therefore secondary glaucoma
Perivascular lymphocytes
What will you see on histo of ERU?
Phacoclastic
This form of uveitis is due to a ruptured lens capsule and release of its proteins.
Gray
What horses commonly get uveal melanocytomas?
Glaucoma
Anterior lens luxation predisposes to what?
Ischemia
Atrophy of the iris and ciliary body from glaucoma is due to chronic pressure induced ___.
Eosinophilic granuloma(s)
Hallmark lesion of Habronemiasis?
True
True or false? Glaucoma can cause lens luxation, and lens luxation and cause glaucoma.
Glaucoma
What is the most common reason for dog and cat enucleations?
Benign
Iridociliary adenomas are almost always (benign/malignant).
Optic cupping, glaucoma
What is this? What can it be secondary to?
Melanin
VKH is an immune mediate disease targeting ___.
Endophthalmitis
Inflammation of the uvea, retina, and ocular cavities
Speed
Diffuse iris melanomas are totally variable in ___ of progression.
ERU
One of the most common causes of blindness in horses
Primary ocular sarcoma
This ocular neoplasia in cats starts with traumatic lens rupture, and then the lens epithelial cells become mesenchymal, and then neoplastic.
