ametropia Any error in refraction where the images do not focus properly on the retina
anisocoria Condition in which the pupils are unequal in size
astigmatism Condition where the eye does not focus properly because of 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
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
dacryoadenitis Inflammation of the lacrimal gland
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 of the eye enabling light to focus on the retina
entropion Inversion of the edge of an eyelid
esotropia Cross-eyes, strabismus characterized by an inward deviation of one or both eyes
exotropia Walleye, strabismus characterized by the outward deviation of one eye relative to the other
fluorescein angiography Radiographic study of the blood vessels in the retina of the eye following the IV injection of a fluorescein dye as a contrast medium
glaucoma Group of diseases characterized by increased intraocular pressure that causes damage to retinal nerve fibers
hemianopia Blindness in one-half of the visual field
hordeolum Pus-filled and often painful lesion on the eyelid resulting from an acute infection in a sebaceous gland
hyperopia Farsightedness, defect in which light rays focus beyond the retina
infectious myringitis Contagious inflammation that causes painful blisters on the ear drum
iridectomy Surgical removal of a portion of the tissue of the iris
iritis Inflammation of the uvea affecting primarily the iris and the structures in front of the eye
keratitis Inflammation of the cornea
labyrinthectomy Surgical removal of all or a portion of the labyrinth
laser trabeculoplasty Used to treat open-angle glaucoma by creating openings in the trabecular meshwork to allow the fluid to drain properly
mastoidectomy Surgical removal of mastoid cells
mydriasis Dilation of the pupil
myopia Nearsightedness, defect in which the light rays focus in front of the retina
myringotomy Small surgical incision in the ear drum to relieve pressure from excess pus or fluid, or to create an opening for the placement of ear tubes
nyctalopia Night blindness, condition in which an individual with normal daytime vision has difficulty seeing at night
nystagmus Involuntary, constant, rhythmic movement of the eyeball
ophthalmoscopy Funduscopy, use of an ophthalmoscope to visually examine the fundus (back part) of the eye
optometrist Holds a doctor of optometry degree and provides primary eye care
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 conductive hearing loss
papilledema Choked disc, swelling/inflammation of the optic nerve at the point of entry into the eye
periorbital edema Swelling of the tissues around 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
presbyopia Condition of common changes in the eyes that occur with aging
ptosis Drooping of the upper eyelid that is usually due to paralysis
radial keratotomy Surgical procedure to treat myopia causing the cornea to bulge outward
retinopexy 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 insertion of a small prosthetic device known as a piston that conducts sound vibrations to the inner ear
strabismus Disorder in which the eyes point in different directions or are not aligned correctly
tarsorrhaphy Partial or complete suturing together of the upper and lower eyelids to protect the 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 are often combined with nausea and vomiting
vitrectomy Removal of the vitreous humor and its replacement with clear solution
xerophthalmia Dry eyes, drying of eye surfaces, including the conjunctiva
