ant error of refraction in which the images do not focus properly on the retina
anisocoria
condition where the pupils are equal size
audiometry
use of an audiometer to measure hearing acuity
cataract
loss of transparency of the lens of the eye that causes a progressive loss of visual acuity
chalazion
nodule or cyst, usually on the upper eyelid, caused by obstructed sebaceous gland
dacryoadenitis
inflammation of the lacrimal gland caused by a bacterial, viral or fungal infection
ectropion
eversion of the edge of the eyelid
emmetropia
normal relationship between the refractive power of the eye and the shape of the eye that enables light to focus correctly on the retina
entropion
inversion of the edge of an eyelid
esotropia
strabismus characterized by an inward deviation of one or both eyes
exotropia
strabismus characterized by the outward deviation of one eye relative to the other
fluorescein angiography
photographic study of the blood vessels of the eye following following IV injection of contrast
glaucoma
group of diseases characterized by increased intraocular pressure that causes damage to the optic nerve and retinal nerve
hemianopia
blindness in one half of the visual field
hordeolum
pus filled lesion on the eye lid resulting from an infection in sebaceous glands
hyperopia
vision defect in which light rays focus behind the retina, far sightedness
infectious myringitis
contagious inflammation that causes painful blisters on the eardrum
iritis
inflammation of the uvea primarily affecting structures of the you
keratitis
inflammation if the cornea
labyrinthectomy
surgical removal of all of portion of the labyrinth of the ear
laser iridotomy
uses a focused beam of light to create a hole in the iris of the eye
laser trabeculoplasty
treatment of an open angle glaucoma by creating openings in the trabecular mesh work to allow fluid to drain
mastoidectomy
surgical removal of part of the mastoid process
mydriasis
dilation of the pupil
myopia
defect in which light rays focus in front of the retina, nearsightedness
myringotomy
small surgical incision in the eardrum to relieve pressure from excess pus or fluid or to create an opening for the placement of ear tubes
nyctalopia
condition in which an individual with normal day time vision has difficulty seeing at night

flow of pus from the ear
oterrhea
any discharge from the ear
otosclerosis
ankylosis of the bones of the middle ear resulting in conductive hearing loss
papilledema
swelling and inflammation of the optic nerve at the point of entrance into the eye through the optic duct
periorbital edema
swelling of the tissues surrounding the eye or eyes
pneumatic retinopexy
surgery in which a gas bubble is injected into the vitreous cavity to put pressure on the detached area in a retinal detachment while it heals
presbycusis
gradual sensorineural hearing loss that occurs as the body ages
presbyopia
condition of common changes in the eyes that occur with age
ptosis
dropping of the upper eye lid that is usually due to muscle weakness or paralysis
radial keratotomy
surgical procedure to treat myopia
scleritis
inflammation of the sclera of the eye
stapedectomy
surgical removal of the stapes bone and insertion of a prosthetic device
tarsorrhaphy
partial or complete suturing of the upper and lower eye lids to protect the eye when the lids are paralyzed, and can’t close
tonometry
measurement of intraocular pressure
tympanometry
use of air pressure in the ear canal to test for disorders of the middle ear
vitrectomy
removal of vitreous humor in the eye and it’s replacement with a saline solution
xerophthalmia
drying of eye surfaces, including conjunctiva
