tropo
turn, change
adnexa
aka adnexa oculi, structures outside eyeball: orbit, eye muscles, eyelids, lashes, conjunctiva, lacrimal apparatus
convergence
is the simultaneous inward movement of the eyes toward each other in an effort to maintain single binocular vision as an object comes near
emmetropia
normal relationship between the refractive power of the eye and the shape of the eye that enables light rays to focus correctly on retina
optometrist
specializes in measuring the accuracy of vision to determine whether corrective lenses are needed
blepharoptosis
drooping of upper eyelid that is usually due to paralysis
ectropion
eversion of edge of an eyelid usually affects lower lid thereby exposing the inner surface to irritation and preventing tears from draining
entropion
inversion turning inward of the edge of an eyelid usually affect lower thereby causing the eyelashes to rub against the cornea
hordeolum
aka stye, pus filled lesion on eyelid resulting from infection in a sebaceous gland
chalazion
aka internal stye localized swelling inside eyelid resulting from obstruction of one of the sebaceous glands
conjunctivitis
aka pinkeye, inflammation of conjunctiva caused by infection or allergy
xeropthalmia
aka dry eye dyring of eye surfaces including conjunctiva may be due to disease or lack of vitamin A
scleritis
inflmmation of sclera (white of eye)
keratitis
inflammation of the cornea
pterygium
noncancerous growth that develops on cornea and can grow large enough to distort vision
iritis
inflammation of iris
anisocoria
condition in which the pupils are unequal in size may be congenital or caused by head injury aneurysm or pathology of CNS
cataract
loss of transparency of lens, may be congenital or caused by trauma or disease mostly associated w/ aging
nystagmus
involuntary constant rhythmic movement of eyeball may be congenital or caused by neurological injury or drug use
papilledema
aka choked disk is swelling and inflammation of optic nere at point of entrance into eye thru optic disk, caused by intracranial pressure maybe due to tumor
glaucoma
group of diseases characterized by increased intraocular pressure resulting in damage to retinal nerve fibers and the optic nerve
diplopia
aka double vision, perception of two images of a single object sometimes a symtom of serious undrlying disorder
hemianopia
blindness in one half of visual field
nyctalopia
aka night blindness
presbyopia
describes common changes in eyes that occur w/ aging afgter about age 40 near vision declines
strabismus
aka squint si disorder in which eyes point in different directions or are not alligned correctly b/c eye muscles are unable to focus together
esotropia
aka cross-eyes
exotropia
aka walleye opposite of cross-eye
ametropia
any error of refraction in which images do not focus poperly on retina astigmatism is type of ametropia
astigmatism
condition in which eye does not focus properly b/c of uneven curvature of cornea
hyperopia
aka farsightedness defect in which light rays focus beyond retina, usually after age 40
myopia
MY aka nearsightedness, defect in which light rays focus in front of retina occurs around puberty
amblyopia
dimness of vision or partial loss of sight esp in one eye, w/o detectable disease of the eye
tonometry
measurement of intraocular pressure abnormally hight pressure may be indication of glaucoma
opthalmoscopy
aka funduscopy visual examination of fundus of eye w/ an opthalmoscope
fluorescein angiography
radiographic study of the blood vesels in retina of eye following the intravenous injection of a flouescein dye as a contrast medium
tarsorrhaphy
partial or complete sutruing together of upper and lower eyelids
iridectomy
surgical removal of a portion of the tissue of the iris
radial keratotomy
surgical proc. to correct myopia, incisions are made partially thru cornea that cause it to flatten
vitrectomy
removal of vitreous fluid and its replacement w/ a clear solution
phacoemulsification
use of ultrasonic vibration to shatter and break up a cataract making removal easier
laser trabeculoplasty
used to treat chronic or open-angle glaucoma by creating an opening in the trabecular meshwork to allow fluid to drain properly
retinopexy
used to reattach the detached area in a retinal detachment
otomycosis
aka swimmer's ear, fungal infection of th external auditory canal
otopyorrhea
flow of pus from ear
otorrhagia
bleeding from the ear
barotrauma
pressure-related ear discomfort often caused by changes in pressure when flying, driving in mountains, scuba diving, when eustachian tube is blocked
eustachitis
inflammation of eustachian tube
myringitis
inflammation of tympanic membrane
otosclerosis
the ankylosis (fusing) of the bones of the middle ear resulting in a conductive hearing loss
otitis media
inflammation of middle ear
vertigo
sense of whirling, dizziness, loss of balance, nausea, vomiting
tinnitus
ringing or buzzing or roaring sound in one or both ears associated w/ hearing loss or prolonged exposure to loud noise
presbycusis
gradual loss of sensorineural hearing that occurs as body ages
tympanometry
measurement of acoustical energy absorbed or reflected by middle ear thru use of probe placed in ear canal
mastoidectomy
surgical removal of mastoid cells
myringotomy
surgical incision of eardrum to create and oppening for placement of tympanostomy tubes
tympanostomy tubes
aka pediatric ear tubes, tiny ventilating tubes placed thru eardrum to provide ongoing drainage for fluids and to relieve pressure that can buildup after childhood ear infections
stapedectomy
surgical removal of the top portion of stapes bone and the insertion of a small prosthetic device called a piston that conducts sound vibes to inner ear
