Flashcards in Special senses terms Deck (46):
1

Aqueous flare

An increase in protein content within the aqueous humor --> inc. light scatter

2

Cataract

opacification of the lens

3

Corneal edema

Injury to the corneal epithelium/endothelium/inflammation of the cornea -
"Blue eye" - Cloudy

4

Dyscoria

Abnormality in shape of the pupil

5

Keratic precipitates

Small clusters of macrophages/neutrophils adherent to corneal
endothelium - "speckles"

6

Keratoconjunctivitis Sica

Dry eye

7

Keratitis

Inflammation of the cornea

8

Keratomalacia

Melting ulcer

9

Neovascularization

small blood vessels forming a ring to injured area of cornea

10

Conjunctivitis

Inflammation of the conjunctiva

11

Chemosis

Severe conjunctival edema

12

Staphyloma

Iris ruptured through descmet's membrane and healed into the cornea (causing
a corneal pigmentation)

13

Hypopyon

Accumulation of neutrophils and fibrin (exudate) that settles centrally within the
anterior chamber

14

Gondiodsygenesis

Malformation of filtration angle

15

Rubeosis Iridis

Reddening of the Iris

16

Posterior Synechia

Fibrous adhesions between Iris & lens

17

Anterior Synechia:

Fibrous adhesions between Iris & cornea

18

Bupthalmus

Enlargement of the eye

19

Blepharitis

Inflammation of the eyelid

20

Blepharospasm

Involuntary tight closure of eyelids

21

Phacolytic

Leakage of lens proteins from hyper mature cataract

22

Phacoclastic

Rupture of lens

23

Chalazion

Granulomatous inflammation directed against Meibomean gland

24

Stye

Common name for bacterial infection of hair follicle/Meibomean gland (S. Aureus
usually)

25

Phthisis bulbi

End stage eye --> Shrunken/atrophied/fibrotic eye

26

Miosis

excessive constriction of the pupil

27

Anterior uveitis

Inflammation of Iris & ciliary body (Iridis/cyclitis)

28

Posterior uveitis

Inflammation of Choroid (choroiditis)

29

Chorioretinitis

Inflammation of Choroid & retina

30

Endophthalmitis

Inflammation of Uvea, Retina, and Vitreous (all interior structures)

31

Panophthalmitis

Endophthalmitis + Cornea + Sclera (interior & outer covering)

32

Hyphema

Blood in anterior chamber

33

Cyclopia/Synopthalmos

Incomplete separation of the orbits during embryogenesis

34

Anophthalmia

RARE, No detectable development even of primary optic vehicle

35

Microphthalmia:

Miniature, disorganized globe in an orbit of relatively normal size

36

Ankyloblepharon:

normal fusion of eyelids

37

Distichia:

Ectopic row of cilia originating from the ducts of the Meibomean glands (usually
bilateral)

38

Ectropion

Outward gaping of eyelid margin, created by undue laxity of excessively long
eyelids

39

Entropion:

Inward rolling of eyelid margin because of inadequate overall length

40

Trichiasis

Misdirection of normal cilia so that they contact the cornea

41

Dermoid

portion of the cornea remains as skin with hair (failure of the fetal ectoderm to undergo complete "metaplasia")

42

Coloboma

Notch like defects of optic disk, retina, and/or uvea --> defective closure of embryonic fissure (collie eye anomaly)

43

Scleral Ectasia

Prevention of proper local formation of choroid & sclera/ bulging of sclera

44

Ectopic cilia:

Abnormally placed cilia within laminar proprietary of conjunctiva

45

Aniridia

Rare, anomaly of extreme Iris Hypoplasia

46

Iris Bombe

Anterior bowing of the Iris - diffusely adhered to the lens
