Flashcards in Chap 17, The Eye, Pathology Deck (27)
1

cataract

Clouding or loss of transparency of the lens of the eye, a type of degenerative eye disease.

2

chalazion

Small, hard mass (granuloma) on the eyelid.

3

diabetic retinopathy

Disease of the retina due to long-term effects of diabetes.

4

glaucoma

Fluid accumulation in the anterior and posterior chambers of the eye causing increased pressure and damage to the retina and optic nerve with loss of peripheral vision (world gets smaller and smaller).

5

trabeculoplasty

Laser surgery that creates perforations in the trabeculum, to drain built up aqueous humor and relieve pressure.

6

tonometry

Measurement of tension and pressure within the eye; glaucoma test.

7

hordeolum (stye or sty)

Inflammation of an oil-secreting gland in the eyelid; stye.

8

macular degeneration

Deterioration of the macula of the retina and producing a loss of central vision.

9

nystagmus

Repetitive, rhythmic movements of one or both eyes.

10

retinal detachment

Separation of the two layers of the retina from each other.

11

photopsia

Bright flashes of light

12

floaters

black spots or filmy shapes

13

scleral buckle

Procedure to suture a band of silicone on the sclera directly over a detached portion of the retina.

14

pneumatic retinopexy

A gas bubble is injected into the vitreous cavity to put pressure on the area of retinal tear until the retina is reattached.

15

strabismus

Abnormal deviation of the pupils; esotropia or exotropia are examples.

16

esotropia

One eye turns inward; cross-eyed.

17

exotropia

One eye turns outward; wall-eyed.

18

hypertropia

Upward deviation of one eye.

19

hypotropia

Downward deviation of one eye.

20

amblyopia

Partial loss of vision or lazy eye.

21

diplopia

Double vision.

22

dacryocystitis

Dacryocystitis is an inflammation of the tear sac (lacrimal sac) at the inner corner of the eye.

23

ectropion

Outward sagging and eversion of the eyelid, leading to improper lacrimation and corneal drying and ulceration.

24

entropion

Inversion of the eyelid, causing the lashes to rub against the eye; corneal abrasion may result.

25

hordeolum (stye)

Infection of a sebaceous gland producing a small, superficial white nodule along lid margin.

26

ptosis

Drooping of upper lid margin as a result of neuromuscular problems or trauma.

27

xanthelasma

Raised yellowish plaque on eyelid caused by lipid disorder.
