ametropia
any error of refraction in which images do not focus properly on the retina
anisocoria
a condition in which the pupils are unequal size
astigmatism
condition in which the eye does not focus properly because of uneven curvatures of the cornea
audiometry
The use of an audiometer to measure hearing acuity
cataract
The loss of transparency of the lens of the eye that causes a progressive loss of visual clarity
chalazion
a nodule or cyst, usually on the upper eyelid, caused by obstruction of a sebaceous gland
cochlear implant
an electronic device that bypasses the damaged portion of the ear and directly stimulates the auditory nerve
conjunctivitis
inflammation of the conjunctiva, usually caused by a viral infection, allergy, or irritants
dacryoadenitis
Inflammation of the lacrimal glands caused by a bacterial, viral, or fungal infection
diplopia
the perception of two images of a single object
ectropion
the eversion of the edge of an eyelid
emmetropia
the normal relationship between the refractive power of the eye and the shape of the eye that enables light rays 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.
flurorescein angiography
a photographic study of the blood vessels in the back of the eye following the intravenous injection of fluorescein dye as a contrast medium
glaucoma
a group of diseases characterized by increased intraocular pressure that causes damage to the optic nerve and retinal nerve fibers
hemianopia
blindness in one half of the visual field
hordeolum
a pus0filled lesion on the eyelid resulting from an infection in a sebaceous gland
hyperopia
a vision defect in which light rays focus behind the retina; aka farsightedness
infectious myringitis
a contagious inflammation that causes painful blisters on the eardrum
Uveitis
inflammation of the uvea primarily affecting the structures in the front of the eye
keratitis
inflammation of the cornea
labyrinthectomy
surgical removal of all or a portion of the labyrinth of the ear
laser iridotomy
a procedure using a focused beam of light to create a hole in the iris of the eye
laser trabeculoplasty
treatment of open-angle glaucoma by creating openings in the trabecular meshwork to allow fluid to drain properly
mastoidectomy
surgical removal of part of the mastoid process
mydriasis
the dilation of the pupil
myopia
a defect in which light rays focus in front of the retina; also known as nearsightedness
myringotomy
a small surgical incision in the eardrum to relieve pressure from the excess pus or fluid or to create an opening for the placement of ear tubes
nyctalopia
a condition in which an individual with normal daytime vision has difficulty seeing at night
nystagmus
an involuntary constant rhythmic movement of eyeball that can be congenital or caused by a neurological injury or drug use
Ophthalmoscopy
the visual examination of the fundus of the eye with ophthalmoscope
Optometrist
holds a doctor of 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
a fungal infection of the external auditory canal
otopyorrhea
the 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
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
photophobia
excessive sensitivity to light and can be the result of migraines, excessive wearing of contact lenses, drug use, or inflammation
pneumatic retinopexy
a 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
a gradual sensorineural hearing loss that occurs as the body ages.
Presbyopia
condition of the common changes in the eyes that occur with aging
ptosis
drooping of the upper eyelid that is usually due to muscle weakness or paralysis
radial keratotomy
a surgical procedure to treat myopia
scleritis
inflammation of the sclera of the eye
sensorineural hearing loss
hearing loss that develops when the auditory nerve or hair cells in the inner ear are damaged
stapedectomy
surgical removal of the stapes bone and the insertion of a prosthetic device that conducts sound vibrations to the inner ear.
strabismus
a disorder in which the eyes point in different directions or are not aligned correctly because the eye muscles are unable to focus together
tarsorrhaphy
a 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, or to help corneal lesions heal
tinnitus
a condition of ringing, buzzing, or roaring sound in one or both ears.
tonometry
the measurement of intraocular pressure
tympanometry
the use of air pressure in the ear canal to test for disorders of the middle ear
vertigo
a sense of whirling, dizziness, and the loss of balance, often combined with nausea and vomiting
vitrectomy
the removal of the vitreous humor in the eye and its replacement with a saline solution
Xerophthalmia
Drying of the eye surfaces, including the conjunctiva.
