OD

A

Right

2
Q

OS

A

Left

3
Q

OU

A

Both eyes

4
Q

Photopic

A

well lit environment

5
Q

Scotopic

A

Dark environment

6
Q

Retroillunimination

A

Using light shone into the eye to reflect against internal structure and highlight features

7
Q

Retropulsion

A

Applying light pressure to both ass to assess for asymmetry

*space occupying lesions add resistance

8
Q

Corneal ulceration

A

disruption of corneal epithelium and exposure of the corneal stroma

9
Q

Jones test

A

application of fluorescein dye

Positive - appears at the nares = patent nasolacrimal duct

10
Q

Seidel test

A

Application of fluorescein dye appearance of AH leaking through (?)
Positive - AH leaking through - confirm perforation

11
Q

Bony orbit

A

part of adnexa, conical bony continuing eyeball

12
Q

Periorbital cone

A

supportive cone like structure

eyeball, extraoccular m, fat, vessels, n, fascia

13
Q

Orbital ligament

A

forms lateral boundary of cats and dogs

14
Q

Exophthalomas

A

abnormal protrusion - NORMAL size

15
Q

Buphthalmos

A

abnormal enlargement of the eyeball - NORMAL position

ie glaucoma

16
Q

Enophthalmos

A

abnormal recession within orbit

17
Q

Stabismus

A

deviation of one or both eyes

18
Q

Horners syndrome

A

sympathetic denervation of the eye and ocular adnexa

CS: enophthalmos, ptosis, miosis, protrusion of 3rd eyelid

19
Q

Microphthalmos

A

Congential small and malformed globe

20
Q

Phthisis bulbi

A

acquired shrunken globe

ie inflammation

21
Q

Proptosis

A

anterior displacement of the glove - eyelids caught behind equator of globe

22
Q

Tarsus

A

fibrocartilaginous layer of eyelid containing meibomian glands
*** Holding layer for surgiacl eyelid clsoure

23
Q

Meibomian glands

A

within tarsal layer - producing lipid layer (sebum) to tear film

24
Q

Canthus

A

convergence of upper and lower eyelids

25
Q

Palpebral fissue

A

Areas outlined by upper and lower eyelid margins

26
Q

Ptosis

A

drooping eyelid caused by sympathetic denervation (HORNERS)

27
Q

Lagophthalmos

A

Incomplete eyelid closure/coverage of the globe

28
Q

Eyelid margin

A

ID by grey line of meibomian glands

**important for surgical closures

29
Q

Entropion

A

rolling of eyelid margin - inward

Hairs touch ocular surface

30
Q

Ectropion

A

Rolling of eyelid margin - outward

2˚ keratitis, conjunctivitis

31
Q

Blepharospasm

A

Spasm of orbicularis oculi m

Squinting

32
Q

Tarsorrhaphy

A

Sx procedure: suture eyelids closed
Temporary/permanent
Partial/complete

33
Q

Trichiasis

A

Hairs growing from normal skin reach corneal and or conjunctival surface

34
Q

Distichia

A

Cilia which emerge from meibomian glands

35
Q

Ectopic cilia

A

cilli protruding through palpebral conjunctiva
12 o’clock
severe, intermittent pain and corneal ulceration

36
Q

Blepharitis

A

inflammation of the eyelids

37
Q

conjunctival fornix

A

where palpebral and bulbar conjunctiva meet

38
Q

Palpebral and bulbar conjunctiva

A

line inner eyelid and anterior globe

39
Q

Epiphora

A

abnormal overproduction of tears

40
Q

Conjunctival lymphoid follicles

A

response to non-specific Ag stimulation
Presence anywhere but the bulbar surface of the 3rd eyelid is abnormal = conjunctivitis
AKA they are only normal on the 3rd eyelid

41
Q

Goblet cells

A

present in conjunctival epithelium - produce inner most mucus layer of tear film

42
Q

Mucoid discharge

A

common CS w/ conjunctivitis (goblet cell origin)

43
Q

Mucopurulent discharge

A

KCS due to loss of aqueous portion of tear film

Bacterial overgrowth, WBC recruitment

44
Q

Conjunctival hyperemia

A

congestion of superficial vessels in conjunctiva - Superficial disease

45
Q

Episcleral injection

A

Refers to congestion of deep conjunctival vessels (episcleral) = deep disease process
