29
Q

Strabismus characterized by an inward deviation of one eye or both eyes; also known as cross-eyes.

A

Eustachian tubes

31
Q

means outside the eyeball

A

Extraocular

32
Q

is a pit in the middle of the macula. Color vision is best in this area because it contains a high concentration of cones and no rods.

A

Fovea centralis

33
Q

is the application of fluorescent dye to the surface of the eye via eye drops or a strip applicator. This dye causes a corneal abrasion to temporarily appear bright green.

A

fluorescein staining

34
Q

A group of eye diseases characterized by increased intraocular pressure (IOP) that causes damage to the optic nerve and retinal nerve fibers.

A

Glaucoma

35
Q

A vision defect in which light rays focus beyond the retina; also known as farsightedness.

A

Hyperopia

36
Q

The surgical removal of a portion of the iris tissue.

A

Iridectomy-

37
Q

inflammation of the uvea affecting primarily structures in the front of the eye.

A

Iritis-

38
Q

consists of a duct at the inner corner of each eye. These ducts collect tears and empty them into the lacrimal sacs. Crying is the overflowing of tears.

A

Lacrimal canal

39
Q

uses a focused beam of light to create a hole in the iris of the eye.

A

laser iridotomy

40
Q

is a gradually progressive condition in which the macula at the center of the retina is damaged, resulting in the loss of central vision but not in total blindness.

A

Macular degeneration

41
Q

The surgical removal of mastoid cells.

A

Mastoidectomy

42
Q

a rare inner ear condition that can affect your balance and hearing.

A

Ménière’s disease-

43
Q

tests involving one ear

A

monaural testing

44
Q

A vision defect in which light rays focus in front of the retina; also known as nearsightedness.

A

Myopia

45
Q

Involuntary, constant, rhythmic movement of the eyeball.

A

Nystagmus

46
Q

The visual examination of the fundus (back part) of the eye with an ophthalmoscope; also known as funduscopy.

A

Ophthalmoscopy

47
Q

A specialist who holds a Doctor of Optometry degree and provides primary eye care, including diagnosing eye diseases and conditions and measuring the accuracy of vision to determine if corrective lenses are needed.

A

Optometrist-

48
Q

Inflammation of the middle ear.

A

Otitis media

49
Q

A fungal infection of the external auditory canal; also known as swimmer’s ear.

The flow of pus from the ear.

A

Otopyorrhea

51
Q

Any discharge from the ear.

A

Otorrhea

52
Q

Ankylosis of the bones of the middle ear, resulting in a conductive hearing loss.

A

Otosclerosis

53
Q

Swelling and inflammation of the optic nerve at the point of entrance into the eye through the optic disk; also known as choked disk.

A

Papilledema

54
Q

Swelling of the tissues surrounding the eye or eyes.

A

Periorbital edema

55
Q

Excessive sensitivity to light.

A

Photophobia

56
Q

the back two-thirds of the eye that includes the anterior hyaloid membrane and all structures behind it: the vitreous humor, retina, choroid, and optic nerve.

A

posterior segment-

57
Q

A gradual sensorineural hearing loss that occurs as the body ages.

A

Presbycusis

58
Q

is a progressive degeneration of the retina that affects night and peripheral vision.

A

Retinitis pigmentosa

59
Q

also known as blind spot, is an abnormal area of diminished vision surrounded by an area of normal vision.

A

Scotoma-

60
Q

Deafness that develops when the auditory nerve or hair cells in the inner ear are damaged.

A

Sensorineural hearing loss-

61
Q

A disorder in which the eyes point in different directions or are not aligned correctly because the eye muscles are unable to focus.

A

Strabismus

62
Q

is bleeding between the conjunctiva and the sclera. This condition, which is usually caused by an injury, creates a red area over the white of the eye.

A

subconjunctival hemorrhage
