302: Ch. 14

adaptation of the ye for near vision by increasing the curvature of the lens

Unequal pupil size

gray-white arc or circle around the limbus of the iris that is common with aging

pupil does not react to light; does constrict with accommodation

refractive error of vision due to differences in curvature in refractive surfaces of the eye (cornea and lens)

crossing paths of an artery and vein in the ocular fundus

loss of both temporal visual fields

inflammation of the glands and eyelash follicles along the margin of the eyelids

opacity of the lens of the eye that develops slowly with aging and gradually obstructs vision

infection or retention cyst of the meibomian gland, showing as a deady nodule on the eyelid

• infection of the conjunctiva
• "pink eye"

abnormal soft exudates visible as gray-white areas on the ocular fundus

• ratio of the width of the physiologic cup to the width of the optic disc
• normally half or less

unit of strength of the lens settings on the ophthalmoscope that changes focus on the eye structures

double vision

• benign deposits on the ocular fundus that show as round yellow dots
• occur commonly with aging

lower eyelid loose and rolling outward

lower eyelid rolling inward

protruding eyeballs

area of keenest vision at the center of the macula on the ocular fundus

a group of eye diseases characterized by increased intraocular pressure

red, painful pustule that is a localized infection of hair follicle at eyelid margin

round darker area of the ocular fundus that are localized dilations of small vissels

the abnormal white rim of sclera visible between the upper eyelid and the iris when a person moves the eyes downward

abnormal finding of round red dots on the ocular fundus that are localized dilations of small vessels

constricted pupils

dilated pupils

• "nearsighted"
• refractive error in which near vision is better than far vision

involuntary, repid, rhythmic movement of the eyeball

• oculus dexter
• right eye

pallor of the optic disc due to partical or complete death of optic nerve

area of ocular fundus in which blood vessels exit and enter

• oculus sinster
• left eye

• stasis of blood flow out of the ocular fundus
• sign of increased intracranial pressure

decrease in power of accommodation that occurs with aging

triangular opaque tissue on the nasal side of the conjunctiva that grows toward the center of the cornea

drooping of upper eyelid over the iris and possibly covering pupil

red glow that appears ot fill the person's pupil when first visualized through the ophthalmoscope

• squint, crossed eye
• disparity of the eye axes

soft, raised yellow plaques occurring on the skin at the inner corners of the eyes
