scler/o
Hard
Dimness of vision or the partial loss of sight, especially in one eye, without detectable disease of the eye.
Amblyopia
A condition in which the eye does not focus properly because of uneven curvatures of the cornea.
Astigmatism
The use of an audiometer to measure hearing acuity.
Audiometry
occurs as the eardrum vibrates and causes the auditory ossicles of the middle ear to vibrate.
Bone conduction
The loss of transparency of the lens of the eye that causes a progressive loss of visual clarity.
Cataract
also known as earwax, is secreted by ceruminous glands that line the auditory canal. This sticky yellow-brown substance has protective functions because it traps small insects, dust, debris, and some bacteria to prevent them from entering the middle ear.
Cerumen-
is a set of muscles and suspensory ligaments that adjust the thickness of the lens to refine the focus of light rays on the retina.
Choroid
Inflammation of the conjunctiva, usually caused by an infection or allergy; also known as pinkeye.
Conjunctivitis
is the simultaneous inward movement of the eyes toward each other. This occurs in an effort to maintain single binocular vision as an object comes nearer.
Convergence
The perception of two images of a single object; also known as double vision.
Diplopia
The eversion (turning outward) of the edge of an eyelid.
Ectropion
The normal relationship between the refractive power of the eye and the shape of the eye that that enables light rays to focus correctly on the retina.
Emmetropia
is the removal of the eyeball, leaving the eye muscles intact.
Enucleation
The inversion (turning inward) of the edge of an eyelid.
Entropion
Strabismus characterized by an inward deviation of one eye or both eyes; also known as cross-eyes.
Esotropia
also known as the auditory tubes, are narrow tubes that lead from the middle ear to the nasal cavity and the throat.
Eustachian tubes
means outside the eyeball
Extraocular
is a pit in the middle of the macula. Color vision is best in this area because it contains a high concentration of cones and no rods.
Fovea centralis
is the application of fluorescent dye to the surface of the eye via eye drops or a strip applicator. This dye causes a corneal abrasion to temporarily appear bright green.
fluorescein staining
A group of eye diseases characterized by increased intraocular pressure (IOP) that causes damage to the optic nerve and retinal nerve fibers.
Glaucoma
A vision defect in which light rays focus beyond the retina; also known as farsightedness.
Hyperopia
The surgical removal of a portion of the iris tissue.
Iridectomy-
inflammation of the uvea affecting primarily structures in the front of the eye.
Iritis-
consists of a duct at the inner corner of each eye. These ducts collect tears and empty them into the lacrimal sacs. Crying is the overflowing of tears.
Lacrimal canal
uses a focused beam of light to create a hole in the iris of the eye.
laser iridotomy
is a gradually progressive condition in which the macula at the center of the retina is damaged, resulting in the loss of central vision but not in total blindness.
Macular degeneration
The surgical removal of mastoid cells.
Mastoidectomy
a rare inner ear condition that can affect your balance and hearing.
Ménière’s disease-
tests involving one ear
monaural testing
A vision defect in which light rays focus in front of the retina; also known as nearsightedness.
Myopia
Involuntary, constant, rhythmic movement of the eyeball.
Nystagmus
The visual examination of the fundus (back part) of the eye with an ophthalmoscope; also known as funduscopy.
Ophthalmoscopy
A specialist who 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 if corrective lenses are needed.
Optometrist-
Inflammation of the middle ear.
Otitis media
A fungal infection of the external auditory canal; also known as swimmer’s ear.
Otomycosis
The flow of pus from the ear.
Otopyorrhea
Any discharge from the ear.
Otorrhea
Ankylosis of the bones of the middle ear, resulting in a conductive hearing loss.
Otosclerosis
Swelling and inflammation of the optic nerve at the point of entrance into the eye through the optic disk; also known as choked disk.
Papilledema
Swelling of the tissues surrounding the eye or eyes.
Periorbital edema
Excessive sensitivity to light.
Photophobia
the back two-thirds of the eye that includes the anterior hyaloid membrane and all structures behind it: the vitreous humor, retina, choroid, and optic nerve.
posterior segment-
A gradual sensorineural hearing loss that occurs as the body ages.
Presbycusis
is a progressive degeneration of the retina that affects night and peripheral vision.
Retinitis pigmentosa
also known as blind spot, is an abnormal area of diminished vision surrounded by an area of normal vision.
Scotoma-
Deafness that develops when the auditory nerve or hair cells in the inner ear are damaged.
Sensorineural hearing loss-
A disorder in which the eyes point in different directions or are not aligned correctly because the eye muscles are unable to focus.
Strabismus
is bleeding between the conjunctiva and the sclera. This condition, which is usually caused by an injury, creates a red area over the white of the eye.
subconjunctival hemorrhage
A ringing, buzzing, or roaring sound in one or both ears.
Tinnitus
is the surgical correction of a damaged middle ear, either to cure chronic inflammation or to restore function.
Tympanoplasty
A sense of whirling, dizziness, and the loss of balance, often combined with nausea and vomiting.
Vertigo
