known as lazy eye

Retinal effects of diabetes mellitus include microaneurysms,
hemorrhages, dilation of retinal veins, and neovascularization (new
blood vessels form in the retina).

38
Q

glaucoma

hordeolum (stye or sty)

A

Localized, purulent, inflammatory staphylococcal infection of a
sebaceous oil-producing gland in the eyelid

40

macular degeneration

A

Progressive damage to the macula of the retina

41
Q

nystagmus

A

Repetitive rhythmic movements of one or both eyes

42
Q

retinal detachment

A

Two layers of the retina separate from each other

43
Q

strabismus

A

Abnormal deviation of the eye.

44
Q

fluorescein angiography

A

Intravenous injection of fluorescein (a dye) followed by serial
photographs of the retina through dilated pupils.

45
Q

slit lamp microscopy

A

Examination of anterior ocular structures under microscopic

magnification.

46
Q

visual acuity test

A

Clarity of vision is assessed

47
Q

visual field test

A

Measurement of the entire scope of vision (peripheral and central).

48
Q

enucleation

A

Removal of the entire eyeball.

49
Q

keratoplasty

A

keratoplasty

50
Q

laser photocoagulation

A

Intense, precisely focused light beam (argon laser) creates an
inflammatory reaction that seals retinal tears and leaky retinal blood
vessel

51
Q

LASIK

A

Use of an excimer laser to correct errors of refraction (myopia,
hyperopia, and astigmatism).

52
Q

phacoemulsification

A

Ultrasonic vibrations break up the lens; the pieces are then aspirated
through the ultrasonic probe

53
Q

scleral buckle

A

Suture of a silicone band to the sclera over a detached portion of the
retina.

54
Q

pinna, or auricle

A

Sound waves enter the ear through the pinna, or auricle [1], which is the projecting part,
or flap, of the ear.

55
Q

cerumen

A

ershi

56
Q

ossicles

A

These bones, in the order of their vibration, are the malleus [4],
the incus [5], and the stapes [6]

57
Q

oval window

A

which separates the middle from the inner ear

58
Q

auditory

or eustachian tube

A

8] is a canal leading from the middle ear to the pharynx. It normally is
closed but opens on swallowing. In an efficient way, this tube can prevent damage to the
eardrum and shock to the middle and inner ears

59
Q

labyrinth

A

The inner ear is also called the labyrinth because of its circular, mazelike structure

60
Q

cochlea

A

The cochlea contains special auditory liquids called

perilymph and endolymph through which the vibrations trave

61
Q

vestibule

A

The vestibule [11] connects the cochlea (for hearing) to three
semicircular canals [12] (for balance). The semicircular canals (containing two membranous
sacs called the saccule and utricle) contain a fluid, endolymph, as well as sensitive hair
cells.

73
Q

cholesteatoma

A

Collection of skin cells and cholesterol in a sac within the middle ear.

74
Q

Meniere disease

A

Disorder of the labyrinth of the inner ear; elevated endolymph pressure
within the cochlea (cochlear hydrops) and semicircular canals
(vestibular hydrops).

A

Sensation of noises (ringing, buzzing, whistling, booming) in the ears.

78
Q

A

Sensation of irregular or whirling motion either of oneself or of external
objects.

A

Testing the sense of hearing

80
