Flashcards in Eye: Diagnostic & Symptomatic Terms Deck (44):
1

eye strain

asthenopia

2

involuntary contraction of the muscles surrounding the eye, causing uncontrolled blinking and lid squeezing

blepharospasm

3

double vision

diplopia

4

abnormal protrusion of one or both eyeballs

exophthalmos

5

secretion of tears

lacrimation

6

involuntary, rapid oscillating movement of the eyeball

nystagmus

7

extreme sensitivity to, and discomfort from, light

photophobia

8

blind spot in vision

scotoma

9

defects in the bending of light as it enters the eye, causing an improper focus in the retina

refractive errors

10

distorted vision caused by an oblong or cylindrical curvature of the lens or cornea that prevents light rays from coming to a single focus on the retina

astigmatism

11

farsightedness; difficulty seeing close objects when light rays extend beyond the proper focus on the retina

hyperopia

12

nearsightedness; difficult seeing distant objects when light rays fall short of the proper focus on the retina

myopia

13

impaired vision owing to old age loss of accommodation

presbyopia

14

ability of the eye to adjust focus on near objects

accommodation

15

decreased vision in early life due to a functional defect that can occur as a result of strabismus, refractive errors or trauma; usually occurs in one eye, also know as lazy eye

ambylopia

16

absence of the lens, usually after cataract extraction

aphakia

17

inflammation of the eyelid

blepharitis

18

baggy eyelid; overabundance and loss of elasticity of skin on the upper eyelid, causing a fold of skin to hang down over the edge of the eyelid when the eyes are open

blepharochalasis

19

baggy eyelid; overabundance and loss of elasticity of skin on the upper eyelid, causing a fold of skin to hang down over the edge of the eyelid when the eyes are open

dermatochalasis

20

drooping of the eyelid usually caused by paralysis (aka ptosis)

blepharoptosis

21

chronic modular inflammation of a meibomian gland, usually the result of a blocked duct; commonly presents as a swelling of the upper or lower eyelid

chalazion

22

opaque clouding of the lens causing decreased vision

cataract

23

pinkeye; inflammation of the conjunctiva

conjunctivitis

24

inflammation of the lacrimal gland

dacryoadenitis

25

inflammation of the tear sac

dacryocystitis

26

disease of the retina in diabetics characterized by capillary leakage, bleeding, and new vessel formation, leading to scarring and loss of vision

diabetic retinopathy

27

outward turning of the rim of the eyelid

ectropion

28

inward turning of the rim of the eyelid

entropion

29

abnormal overflow of tears caused by blockage of lacrimal duct

epiphora

30

group of disease of the eye characterized by increased intraocular pressure that results in damage of the optic nerve, producing defects in vision

glaucoma

31

sty; an acute infection of a sebaceous gland of the eyelid

hordeolum

32

inflammation of the iris

iritis

33

inflammation of the cornea

keratitis

34

breakdown or thinning of the tissues in the macula, resulting in partial or complete loss of central vision

macular degeneration

35

eye in which the natural lens is replaced with an artificial lens implant

pseudophakia

36

fibrous growth of conjunctival tissue that extends onto the cornea

pterygium

37

separation of the retina from the underlying epithelium, disrupting vision and resulting in blindness if not repaired

retinal detachment

38

inflammation of the retina

retinitis

39

crossed eyes; a condition of eye misalignment caused by an intraocular muscle imbalance

strabismus

40

when each eye at resting position is not consistent with each other

heterotropia

41

right or left eye deviates inward toward the nose

esotropia

42

right or left eye deviates outward away from the nose

exotropia

43

inflammation of the sclera

scleritis

44

misdirected eyelashes that rub on the conjunctiva or cornea

trichiasis
