Terms

Answer 2

contains aqueous humor, includes anterior & posterior chambers: inside of cornea to lens

Question 3

Blepharitis

Answer 3

inflammation of eyelids

Question 4

Blepharospasm

Answer 4

squinting, blinking, involuntary contraction of eyelids

indicates pain

Question 5

Blepharoedema

Answer 5

swelling of eyelids often seen with adverse vaccine reaction or insect bite

Question 6

Answer 6

enlargement of the globe due to glaucoma (increased intraocular pressure)

Question 7

Chemosis

Answer 7

swelling (edema) of conjunctiva

Question 8

Choroid

Answer 8

posterior part of uvea, vascular layer located between the sclera and retina

Question 9

Ciliary Body

Answer 9

part of uvea behind iris

not normally seen on ocular exam

produces aqueous

Question 10

Answer 10

abnormal location of pupil

Question 11

Dyscoria

Answer 11

abnormal shape to pupil

Question 12

Dacryo

Answer 12

refers to lacrimal system

Question 13

Dacryocystitis

Answer 13

inflammation of Nasolacrimal system

Question 14

Descemet’s Membrane

Answer 14

basement membrane of corneal endothelial cells

innermost layer of cornea

Question 15

Descemetocele

Answer 15

exposure of Descemet’s membrane when corneal epithelium and stroma are lost

if breached, the eye is perforated

Question 16

Enophthalmos

Answer 16

recession of the globe deeper into the orbit due to loss of sympathetic tone, loss of periorbital fat, or mass effect

Question 17

Epiphora

Answer 17

overflow of tears

Question 18

ERG

Answer 18

electroretinogram

measures electrical potential of photoreceptor cells

Question 19

Exophthalmos

Answer 19

anterior displacement of the globe from the normal orbital position, globe remains behind eyelids

Question 20

Flare

Answer 20

protein seen in the aqueous due to vascular leakage in uveitis

Question 21

Fundus

Answer 21

area seen through the lens

optic nerve, retinal vessels, tapetal & non-tapetal areas

Question 22

Glaucoma

Answer 22

loss of ganglion cells and optic nerve atrophy usually due to increased intraocular pressure

Question 23

Gray line

Answer 23

refers to areas along meibomian gland openings, surgical reference point

Question 24

Hyphema

Answer 24

RBC’s in anterior chamber

Question 25

Hypopyon

Answer 25

Neutrophils in anterior chamber

Question 26

Normal IOP

Answer 26

10-20 mmHg in dogs may be slightly higher in cats and horses

Question 27

KP’s

Answer 27

keratic precipitates, aggregates of inflammatory cells-lymphocytes, on corneal endothelium

Question 28

Keratitis

Answer 28

inflammation of cornea

Question 29

Keratoconjunctivitis Sicca

Answer 29

insufficient aqueous tear production Schirmer Tear Test = <15mm/min in dogs with clinical signs

Question 30

Lagophthalmos

Answer 30

lids do not close completely over cornea (prominent eye or neurologic deficit

Question 31

Macroblepharon

Answer 31

too large eyelid opening for size of globe

Question 32

Meibomian gland

Answer 32

lipid secreting glands along lid margins

Question 33

Microphthalmia

Answer 33

congenitally small globe

Question 34

Miosis & Mydriasis

Answer 34

Miosis = constricted pupil Mydriasis = dilated pupil

Question 35

Phacoemulsification

Answer 35

surgical breakdown of lens for removal

Question 36

3 Layers of tear film:

Answer 36

Inner - MUCIN secreted by goblet cells - located in palpebral conjunctiva - keeps corneal surface smooth and allows adhesion of aqueous tears to lipophilic cornea Middle - AQUEOUS layer secreted by orbital lacrimal gland and gland of nictitating membrane Outer - LIPID layer secreted by meibomian glands - located along the eyelid margins - holds aqueous tears against eye, prevents evaporation and ‘spilling of tears’

Question 37

Uvea

Answer 37

MIDDLE vascular layer of the eye, iris, ciliary body and choroid

Question 38

Uveitis

Answer 38

inflammation of uvea

Question 39

Answer 39

inflammation of iris & ciliary body

Question 40

Posterior uveitis

Answer 40

inflammation of choroid

Question 41

Panuveitis

Answer 41

inflammation of anterior and posterior uvea
