Term
| Precorneal Film Composition |
|
Definition
external layer-lipid from beibomian gland
central layer-aqueous from lacrimal gland
inner layer-mucous from goblet cells |
|
|
Term
|
Definition
clear, nonkeratinized, nonpigmented epithelium
avascular stroma
enodthelial Na/K pumps out water to prevent edema |
|
|
Term
|
Definition
normal hair on skin growth on the eye
Failure of epidermal differentiation to cornea
Clinical significance depends on amount of irritation |
|
|
Term
|
Definition
just within corneal epithelium
does not go through basal layer or into stroma
will not stain yellow |
|
|
Term
|
Definition
hydrophilic stain
Corneal epithelium is hydrophobic which will repel the dye
Corneal stroma is hydrophilic which will retain the dye
Desmanes membrane is hydrophobic, so if have total loss of stroma which will repel the dye |
|
|
Term
|
Definition
ulceration into corneal stroma
will stain |
|
|
Term
|
Definition
ulceration to desmanes membrane
last layer before perforation of eye
will not stain |
|
|
Term
|
Definition
| a shrunken, non-functional eye that results from severe ocular disease, inflammation, or injury |
|
|
Term
|
Definition
inflammation of the cornea
causes vascularization, scarring, descmetocele, uveitis |
|
|
Term
| Keratoconjunctivitis sicca |
|
Definition
| Abnormality in tear production |
|
|
Term
|
Definition
Isolated fragment of chronic avascular stroma
often due to corneal ulceration healing |
|
|
Term
|
Definition
Chronic Superficial Keratitis
Responsive to immunotherapy
immune mediated often seen in dogs |
|
|
Term
|
Definition
ulceration that tries to heal
basal cells never attack to stroma
epithelium remains disoragnized
florescent dye would leak underneath |
|
|
Term
| Infectious Keratoconjunctivitis |
|
Definition
aka pink eye
caused by moraxella bovis
melting of corneal stroma due to bacterial enzymes |
|
|
Term
|
Definition
increased opacity in the lens
diabetes, insult, post inflammation |
|
|
Term
| Persistent Pupillary Membrane |
|
Definition
| remnants of a fetal membrane that persist as strands of tissue crossing the pupil |
|
|
Term
|
Definition
| swelling and irritation of the uvea, the middle layer of the eye |
|
|
Term
|
Definition
| an inflammation of the middle layer of the eye, which includes the iris (colored part of the eye) and adjacent tissue, known as the ciliary body |
|
|
Term
|
Definition
| an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye |
|
|
Term
|
Definition
| an inflammatory condition of the intraocular cavities (ie, the aqueous and/or vitreous humor) |
|
|
Term
|
Definition
| the inflammation of all coats of the eye including intraocular structures |
|
|
Term
|
Definition
| iris is attached to posterior surface of cornea |
|
|
Term
|
Definition
| iris is attached to the lens |
|
|
Term
|
Definition
corneal edema
glaucoma
synechia
retinal detachment
phthisis bulbi |
|
|
Term
|
Definition
innter retinal atrophy
corneal edema
corneal striae
cataracts
optic nerve atrophy and cupping
