15

double vision

diplopia

16

inflammation of internal tissues of the eye

loss of vision resulting from increased intraocular pressure, damaging the optic nerve

glaucoma

18

infection of a meibomian gland, causing local swelling of the eyelid AKA sty

hordeolum

19

reduced vision of nearby objects AKA farsightedness

hyperopia

20

paralysis of the iris

iridoplegia

21

inflammation of the iris

iritis

22

inflammation of the cornea

keratitis

23

ARMD: progressive deterioration of an area of the retina know as the macula lutea, leading to loss of central vision; most common cause is age

macular degeneration

24

reduced vision of distant objects AKA nearsightedness

myopia

25

poor vision at night or in dim light

nyctalopia

26

involuntary, rhythmic movements of the eye

nystagmus

27

fungal infection of the eye

oculomycosis

28

general term for a disease of the eye

ophthalmopathy

29

paralysis of the eye that affects the muscles moving the eyeball

ophthalmoplegia

30

abnormal fear of light, often caused by abnormal sensitivity to light

photophobia

31

inflammation of the retina caused by extreme light intensity

photoretinitis

32

impaired vision due to aging

presbyopia

33

abnormal fold of fibrous tissue that extends between the conjunctiva & cornea

pterygium

34

inherited disease characterized by night blindness, progressive atrophy, & retinal pigment changes

retinitis pigmentosa

35

malignant tumor that originates from a developing retinal cell

retinoblastoma

36

disease of the retina

retinopathy

37

inflammation of the sclera & cornea

sclerokeratitis

38

softening of the sclera

scleromalacia

39

abnormal blind spot in vision

scotoma

40

condition of crossed eyes caused by the visual axes failing to meet at the same point; causes a noticeable squint & can be characterized as esotropia (one or both eyes deviate inward) or exotropia (one or both eyes deviate outward)

strabismus

41

surgical repair of an eyelid

blepharoplasty

42

surgical excision of a lens that has lost its clarity

cataract extraction

43

VA: test of ability to see details & shape of objects from recorded distances

distance visual acuity

44

excision of an eyeball from the socket

enucleation

45

visual recording of blood vessels in the retina & choroid using fluorescein dye, which is injected into a vein & circulates thru the eye

fluorescein angiography

46

surgical implantation of an artificial lens to replace a defective natural lens

intraocular lens transplant

47

surgical excision of a portion of the iris

iridectomy

48

incision into the iris to allow the aqueous humor to drain from the anterior chamber; usually performed w/ a laser to treat glaucoma

iridotomy

49

procedure using a handheld device called a keratometer, which measures the curvature of the cornea; usually used for fitting contact lenses

keratometry

50

corneal transplant

keratoplasty

51

laser-assisted in situ keratomileusis: use of a laser to reshape the corneal tissue beneath the surface of the cornea to correct vision abnormalities

LASIK

52

variety of procedures using specialized instruments to assist in the diagnosis of eye disorders

ophthalmic evaluation

53

physician who specializes in the treatment of eyes

ophthalmologist

54

field of medicine that focuses on the study of disease related to the eyes

ophthalmology

55

use of handheld instrument w/ a light, called an ophthalmoscope, to view the interior of the eye

ophthalmoscopy

56

technician trained in filling prescriptions for corrective lenses

optician

57

professional trained to examine eyes to correct vision problems & eye disorders

optometrist

58

measurement of vision, usually to test acuity for prescribing corrective lenses; the process includes the use of an optometer, which measures the range & sharpness of vision

optometry

59

use of ultrasound frequencies to break up a cataract, which is then aspirated & removed

phacoemulsification

60

PRK: use of a laser to reshape the cornea in an effort to correct myopia

61

RK: incisions into the cornea to produce a spoke-like effect, which serves to flatten the cornea & correct for myopia

radial keratotomy

62

repair of a detached retina, in which a portion of the sclera is resected & an implant inserted; the suturing of the implant causes the sclera to buckle slightly
