Ch. 14 - Eyes

adaption of the eye for near vision by increasing the curvature of the lens

unequal pupil size

gray-white arc 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 a meibomian gland, showing as a beady nodule on the eyelid
• a small bump in the eyelid caused by a blockage of a tiny oil gland.

• "pinkeye"
• infection of the conjunctiva

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

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

• oculus sinister
• LEFT eye

• oculus dexter
• RIGHT eye

• decrease in power of accommodation that occurs with aging
• farsighted

drooping of upper eyelid over the iris and possibly covering pupil

red glow that appears to fill the person's pupil when first visualized thru the opthalmoscope

• squint, crossed eye
• disparity of eye axes
