angle formed by inner or outer jxn of upper and lower eyelids

plural: canthi
medial: canthus on the side near the nose
lateral: canthus on the side away from the nose

Question 7

caruncle

Answer 7

pink, fleshy conjunctival tissue in the nasal corner of each eye over the semilunar fold

Question 8

cataract

Answer 8

opacity or cloudiness of the crystalline lens, which may prevent a clear image from forming on the retina

surgical removal of the lens may be necessary if visual loss becomes significant, with lost optical power replaced by intraocular lens, contact lens, or aphakic specticales

may be congenital or caused by trauma, disease, or age

many different forms of cataracts

Question 9

chalazion

Answer 9

obstruction and inflammation of the meibomian gland with leakage of sebum into surrounding tissue and resultant lipogranuloma

Question 10

conjunctiva

Answer 10

transparent mucous membrane covering outer surface of the eyeball (except the cornea) and inner surface of the eyelids as one continuous membrane

Question 11

cornea

Answer 11

transparent front part of the eye that covers the iris, pupil and anterior chamber and provides most of the eye’s optical power

five layers: epithelium, bowman’s membrane, stroma, decemet’s membrane, endothelium

Question 12

ectropion

Answer 12

lid margin that does not rest normally against the eyeball but falls, or pulled away, as by a scar- eversion of the eylid margin

can create corneal exposure with excessive drying, tearing, and iirritation

Question 13

entropion

Answer 13

inward tunring of upper or lower eyelid so that the margin rests against the eyeball and rubs eyeball - inversion of the eyelid margin

Question 14

gray line

Answer 14

border between outer and inner layers of the eyelid margin that separates eyelid skin from conjunctival mucous membrane. eyelashes are in front of the line, tarsal gland ducts behind

Question 15

hordeolum

Answer 15

acute bacterial infection of the sebaceous eyelid glands - most commonly meibomian glands (internal hordeolum) or glands of zeiss or moll (external hordeolum) - associated with staph. aureus

Question 16

hyperemia

Answer 16

increased blood flow - usually referes to eye redness caused by congestion of conjunctival blood vessels

Question 17

isocoria

Answer 17

pupils of equal size

Question 18

krukenberg’s spindle

Answer 18

vertical pigment deposit on corneal endothelium - found with pigment dispersion glaucoma and following uveitis

Question 19

lagophthalmos

Answer 19

inability to close eyelids completely, leading to corneal and conjunctival drying

Question 20

meibomian glands

Answer 20

oil glands (one of a series) within the eyelid tissue whose duct opens onto the eyelid margin just behind the gray line. secretions supply the outer portion of the tear film, preventing rapid tear evaporation and tear overflow and providing tight eyelid closure

AKA tarsal gland ducts

Question 21

mittendorf dot

Answer 21

small white spot on the posterior lens capsule that represents a remnant of the posterior tunica vasculosa lentis where the former hyaloid artery attached

Question 22

molluscum contagiosum

self-liminted, mildly contagious skin disease caused by a pox virus. typical lesions are small, dome shaped umbilicated, shiny skin-colored papules

Question 23

ocular adnexa

Answer 23

structures surrounding the eyeball; includes eyelids, eyebrows, tear drainage system, orbial wall, and orbital contents

Question 24

papilloma

Answer 24

refers to a begign cutaneous or mucosal tumor that consists of the cluster of finger like projections of proliferating epithelial and fibrovascular tissues

Question 25

pinguecula

Answer 25

benign, yellowish-brown subconjunctival elevation usually located on either side of the cornea - composed of degenerated elastic tissue

Question 26

pterygium

Answer 26

abnormal wedge-shaped growth on bulbar conjunctiva probably related to sun irritation

magradually advance onto cornea, requiring surgical removal

Question 27

ptosis

Answer 27

abnormally low position (drooping) of the upper lid. may be congenital, caused by paralysis or weakness of CN3 or sympathetic nerves or caused by excessive weight of upper lid

Question 28

punctum (lacrimal)

Answer 28

tiny skin opening of the lacrimal canaliculus of each upper and lower eyelid near the nose

entrance to the tear drainage (lacrimal) system. each punctum is surrounded by small papilla (elevation) of skin

plural: puncta

contains collagen and elastic fibers

Question 30

staphyloma

bulging of the eye surface that includes part of the uvea (iris, ciliary body) into area of thin stretched sclera. if no uveal tissue is included in the stretched area, condition is called ectasia

Question 31

synechia

Answer 31

adhesion (s) that bind the iris to any adjacent structures
