25
Descemet's Membrane
Basement membrane of corneal endothelial cells; innermost layer of cornea
26
Descemetocele
Exposure of Descemet's membrane when corneal epithelium and stroma are lost If breached, the eye is considered perforated
27
Enophthalmos
Recession of the globe deeper into the orbit due to loss of sympathetic tone, loss of periorbital fat, or mass effect
28
Epiphora
Overflow of tears
29
ERG
Electroretinogram - Measures electrical potential of photoreceptor cells
30
Exophthalmos
Anterior displacement of the globe from the normal orbital position, globe remains behind eyelids
31
Fibrous tunic
-Outer fibrous layer of the eye: sclera andd cornea
32
Flare
Protein seen in the aqueous due to vascular leakage in uveitis
33
Foramina
Openings in bony orbit to allow passage of blood vessels and nerves
34
Fundus
Area seen through the lens: optic nerve, retinal vessels, tapetal & non-tapetal areas
35
Glaucoma
Loss of ganglion cells and optic nerve atrophy usually due to increased intraocular pressure
36
Globe
Eyeball
37
Gray line
Refers to areas along Meibomian gland openings, surgical reference point
38
Hyperemia
Diffuse redness of conjunctiva due to capillary and small vessel congestion
39
Hyphema
RBCs in anterior chamber
40
Hypopyon
Neutrophils in anterior chamber
41
Intraocular pressure
Normally 10-20 mmHg in dogs, may be slightly higher in cats and horses
42
Iris
Part of uvea anterior to lens, central opening = pupil - Allows light to enter eye, regulates amount of light by dilating or constricting sphincter
43
KPs
Keratic precipitates - Aggregates of inflammatory cells like lymphocytes on the corneal endothelium
44
Keratitis
Inflammation of cornea
45
Kerato
Refers to cornea
46
Keratoconjunctivitis sicca
- KCS - "Dry eye" - Insufficient aqueous tear production (STT = Schirmer Tear test) <15 mm/min in dogs with clinical signs
47
Lagophthalmos
Lids do not close completely over the cornea (prominent eye or neurologic defect)
48
Limbus
Junction of cornea and sclera
49
Macroblepharon
Too large eyelid opening for size of globe
50
Meibomian gland
Lipid secreting glands along lid margins
51
Microphthalmia
Congenitally small globe
52
Miosis
Constricted pupil
53
Mydriasis
Dilated pupil
54
Nictitans
3rd eyelid - TEL - Nictitating membrane (NM)
55
Non-tapetum
Area of choroid inferior to tapetal area, often pigmented
56
OU
Both eyes
57

Eyelids
60

Eyelid opening
61

Refers to optic nerve
62
Phace
Refers to lens
63
Pachoemulsification
Surgical breakdown of lens for removal
64
Posterior chamber
From posterior iris to the anterior face of the lens
65
Posterior segment
Area between the posterior lens capsule and the retina; contains vitreous
66
Pre-corneal tear film
Has three layers
67
Inner tear film layer
Mucin - Secreted by goblet cells, located in palpebral conjunctiva, keeps corneal surface smooth and allows adhesion of aqueous tears to lipophilic cornea
68
Middle tear film layer
Aqueous - Secreted by orbital lacrimal gland (superior temporal lid) 70% and gland of nictitating membrane GNM (30%) located posterior to 3rd eyelid
69
Outer tear film layer
Lipid - Secreted by meibomian glands located along eyelid margins with 30-40 openings seen on each lid margin - Holds aqueous tears against the eye - Prevents evaporation and spilling of tears
70
Retina
- INNER nervous layer of the eye - Lines the posterior segment of the eye - Contains 10 layers including the outer photoreceptor cells that convert light energy and the inner nerve fiber layer that converges to form the optic nerve
71

72
Scleritis
Inflammation of sclera
73
Tapetum
Reflective layer of choroid (if present)
74
uvea

75
uveitis
Inflammation of uvea
76
