Q

new blood vessel growth into the cornea. (Classic sign of keratitis)

A

Corneal neovascularization.

17
Q

Protein suspended in the anterior chamber that becomes evident when a narrow, bright and focused light source is directed at the eye.(pathognomonic sign of uveitis, graded on a scale of 0-4+)

A

Aqueous flare

18
Q

Blood in the anterior chamber(supportive of uveitis or bleeding disorder)

A

Hyphema

19
Q

alternating color of the iris of one or between eyes.(normal finding)

A

Heterochromia iridis

20
Q

small constricted pupil

A

Miosis

21
Q

Large dilated pupil

A

Mydriasis

22
Q

360 degree posterior synechia such that the iris bulges forward and contours to a doughnut-like shape.(common sequela of uveitis and is a risk factor for glaucoma)

A

Iris bombe

23
Q

Adhesion between iris and lens

A

posterior synechia

24
Q

calcium and phosphate crystals. Sign of vitreal degeneration

A

astroid hyalosis

25
Q

separation of the inner, 9-layer ‘neruosesory retina’ from outermost layer of the retina, the pigmented epithelium

A

Retinal detachment

26
Q

caused either by pulling or tearing forces, pulling is usually caused by scar tissue contraction. usually caused by trauma.

A

Rhegmatogenous retinal detachement

27
Q

caused by disruption of the blood retinal barrier and hematogenous leakage/infiltration of potential space between neurosensory retina and the retinal pigmentedepithelium.

A

Non-rhegmatogenous retinal detachment

28
Q

A 
CN V (afferent)
CN VII (efferent
29
Q

Menace response

A 
CN II (Afferent)
CN VII (Efferent)
Cortical(learned behavior)
30
Q

Pupillary Light Reflex(PLR)

A 
CN II afferent
CN III(oculomotor) Efferent
31
Q

Dazzle Reflex

A

CN II afferent

CN VII efferent

32
Q

Oculocephalic reflex (tracking the head back an forth)

A

Intact CN II, peripheral central vestibular components, CN III, IV, and VI.

33
Q

Corneal reflex

A 
CN V (opthalmic branch)afferent
CN VII efferent
34
Q

Minimum data base for eye procedures

A

Schirmer tear test I, Fluorecein stain, tonometry.

35
