dimness of vision or the partial loss of sight, especially detectable disease of the eye.
ametropia
any error of refraction in which images do not focus properly on the retina.
anisocoria
a condition in which the pupils are unequal in size
astigmatism
condition in which the eye does not fouc properly because of an uneven curvatures of the cornea.
audiometry
use of an audiometer to measure hearing acuity.
cataract
loss of transparency of the lens that causes a progressive loss of visual clarity.
cerumen
earwax, secreted by ceruminous glands that line the auditory canal.
chalazion
nodule or cyst, usually on the upper eyelid, caused by obstruction in a sebaceous gland.
cochlear implant
electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve.
conjunctivitis
pinkeye, inflammation of the conjunctiva that is usually caused by an infection or allergy.
dacryoadentitis
inflammation of the lacrimal gland caused by a bacterial, viral, or fungal infection.
diplopia
double vision, perception of two images of a single object
ectropion
eversion of the edge of an eyelid.
emmetropia
normal relationship between the refractive power of the eye and the shape that enables light rays to focus correctly on retina.
entropion
inversion of the edge of an eyelid.
esotropia
cross-eyes, strabismus characterized by an inward deviation of one or both eyes.
eustachian tubes
auditory tubes, narrow tubes that lead from the middle ear to the nasal cavity and the throat.
exotropia
walleye, strabismus characterized by outward deviation of one eye relative to the other.
fluorescein angiography
radiographic study of blood vessels in the retina of eye following the intravenous injection of fluorescein dye as a contrast medium.
glaucoma
group of diseases characterized by increased intraocular pressure that causes damage to retinal nerve fibers and optic nerve.
hemianopia
blindness in one-half of visual field.
hordeolum
puss-filled and often painful lesion on eyelid resulting from an acute infection in sebaceous gland (stye).
hyperopia
farsightedness, defect in which light rays focus beyond retina.
infectious myringitis
contagious inflammation that causes painful blisters on eardrum.
iridectomy
surgical removal of portion of tissue of the iris.
iritis
Inflammation of the uvea affecting primarily structures in the front of the eye.
keratitis
inflammation of the cornea
labyrinthectomy
surgical removal of all or portion of the labyrinth.
laser trabeculoplasty
used to treat open-angle glaucoma by creating opening in the trabecular meshwork to allow the fluid to drain properly.
mastoidectomy
surgical removal of mastoid cells.
mydriasis
dilation of the pupil
myopia
nearsighteness, defect in which light rays focus in front of the retina.
myringotomy
small surgical incision in the eardrum to relieve pressure from excess pus or fluid to create an opening for the placement of ear tubes.
nyctalopia
night blindness, a condition in which an individual with normal daytime vision has difficultly seeing at night.
nystagmus
involuntary, constant, rhythmic movement of the eyeball that can be congenital or caused by a neurological injury or drug use.
ophthalmoscopy
use of an ophthalmoscope to visually examine the fundus (back part) of the eye.
optometrist
doctor with optometry degree and provides primary eye care, including diagnosing eye diseases and conditions and measuring the accuracy of vision to determine whether corrective lenses are needed.
otitis media
inflammation of the middle ear.
otomycosis
fungal infection of the external auditory canal.
otopyorrhea
flow of pus from the ear
otorrhea
any discharge from the ear
otosclerosis
ankylosis of the bones of the middle ear, resulting in a conducting hearing loss.
papilledema
choked disk, swelling and inflammation of the optic nerve at the point of entrance into the eye through the optic disk.
periorbital edema
swelling of the tissues surrounding the eye or eyes.
photophobia
excessive sensitivity to light and can be the result of migraines, excessive wearing of contact lenses, drug use, or inflammation.
presbycusis
gradual loss of sensorineural hearing that occurs as the body ages.
prebyopia
condition of common changes in the eyes that occur with aging.
ptosis
drooping of the upper eyelid that usually due to paralysis.
radial keratotomy
surgical procedure to treat myopia.
retinopexy
used to reattach the detached area in a retinal detachment
scleritis
inflammation of the sclera
sensorineural hearing loss
nerve deafness, develops when the auditory nerve or hair cells in the inner ear are damaged.
stapedectomy
surgical removal of the top portion of the stapes bone and the insertion of a small prosthetic device (piston) conducts sound vibrations to inner ear.
strabismus
disorder in which eyes point in different directions or not aligned correctly, because the eye muscles are unable to focus together.
tarsorrphaphy
partial or complete suturing together of the upper and lower eyelids to protect eye when the lids are paralyzed and unable to close normally.
tinnitus
condition of ringing, buzzing, or roaring sound in one or both ears.
tonometry
measurement of intraocular pressure
tympanometry
use of air pressure in the ear canal to test for disorders of the middle ear.
vertigo
sense of whirling, dizziness, and loss of balance that is often combined with nausea and vomiting.
vitrectomy
removal of the vitreous humor and its replacement with a clear solution.
xerophthalmia
dry eye, drying of eye surfaces, including the conjunctiva, because the tear glands do not produce enough tears.
