Adaptation of the eye for near vision by increasing the curvature of the lens
|
Accommodation:
|
|
|
unequal pupil size
|
Anisocoria:
|
|
|
pupil does not react to light; does constrict with accommodation
|
Argyll Robertson pupil:
|
|
|
refractive error of vision due to differences in curvature in refractive surfaces of the eye (cornea and lens)
|
Astigmatism:
|
|
|
crossing paths of an artery and vein in the ocular fundus
|
A-V crossing:
|
|
|
loss of both temporal visual fields
|
Bitemporal hemianopsia:
|
|
|
inflammation of the glands and eyelash follicles along the margin of the eyelids
|
Blepharitis:
|
|
|
opacity of the lens of the eye that develops slowly with aging and gradually obstructs vision
|
Cataract:
|
|
|
infection or retention cyst of a meibomian gland, showing as a beady nodule on the eyelid
|
Chalazion:
|
|
|
infection of the conjunctiva, pink eye
|
Conjunctivitis:
|
|
|
lower eyelid loose and rolling outward
|
Ectropion:
|
|
|
lower eyelid rolling inward
|
Entropion:
|
|
|
protruding eyeballs
|
Exophthalmos:
|
|
|
area of keenest vision at the center of the macula on the ocular fundus
|
Fovea:
|
|
|
Glaucoma: a group of eye diseases characterized by increased intraocular pressure
|
Hordelum: stye; red, painful pustule that is a localized infection of hair follicle at eyelid margin
Lid lag: the abnormal white rim of sclera visible between the upper eyelid and the iris when a person moves the eyes downward Macula: round darker area of the ocular fundus that mediates vision only from the central visual field Microaneurysm: abnormal finding of round red dots on the ocular fundus that are localized dilations of small vessels Miosis: constricted pupils Mydriasis: dilated pupils Myopia: “nearsighted” refractive error in which near vision is better than far vision Nystagmus: involuntary, rapid rhythmic movement of the eyeball OD: oculus dexter; right eye Optic atrophy: pallor of the optic disc due to partial or complete death of optic nerve Optic disc: area of ocular fundus in which blood vessels exit and enter OS: oculus sinister or right eye Papilledema: stasis of blood flow out of the ocular fundus; sign of increased intracranial pressure Presbyopia: decrease in power of accommodation that occurs with aging Pterygium: triangular opaque tissue on the nasal side of the conjunctiva that grows toward the center of the cornea Ptosis: drooping of upper eyelid over the iris and possibly covering pupil Red reflex: red glow that appears to fill the person’s pupil when first visualized through the opthalmoscope Strabismus: squint, crossed eye disparity of the eye axes Xanthelasma: soft, raised yellow plaques occurring on the skin at the inner corners of the eyes |
