Epscleritis   Inflammation of the outermost layers of the sclera  
Extraocular   Pertaining to the outside of the eyeball  
Color Blindness (Monochromatism)   An inability to sharply perceive visual colors  
Hemianosia   Loss of vision, or blindness, in one-half of the visual field.  
Keratitis   Corneal inflammation caused by a microorganism, trauma to the eye, a break in the sensory innervatin of the cornea, a hypersensitivity reaction, or a tearing defect.  
Aural   Pertaiing to the ear  
Purulent   Containing pus  
Serous   Pertaining to producing serum  
Keratomycosis   A fungal growth present on the cornea  
Miotic   Anagent that causes the pupil of the eye to constrict  
Mydriatic   An agent that causes the pupil of the eye to dilate  
Mydriasis   Abnormal dilation of the pupil of the eye  
Audiogram   A recording of the faintest sounds an individual is able to hear  
Ectropion   "Turning out" or eversion of the eyelash margins (especially lower lid) from the eyeball, loading to exposure of the eyelid and eyeball surface and lining.  
Entropion   "Turning in" of the eyelash margins (especially lower margins) resulting in the sensation similar to that of a foreign body in the eye (redness, tearing, burning, itching).  
Esotropia   An obvious inward turning of one eye in reaction to the other. AKA: Crosseyes  
Blepharitis   Acute or chronic inflammation of the eyelid margins stemming from seborrheic, allergic, or bacterial origin.  
Blepharoptosis   Occurs when the eyelid partially or entirely covers the eye as a result of a weakened muscle.  
Blepharochalasis   Relaxation of the skin of the eyelid. The skin may droop over the edge of the eyelid.  
Labyrinthitis   Infection/inflammation of the labyrinth or inner ear, specifically the 3 semicircular canals in the inner ear.  
Myringoplasty   Surgical repair of the tympanic membrane with a tissue graft after a spontaneous rupture that results in hearig loss. AKA: Tympanoplasty  
Myringotomy   Surgical incision into the eardrum.This procedure is performed to relieve pressure or release fluid frm the middle ear. AKA: Tympanotomy  
Tinnitus   A ringing or tinkling noise heard in the ears.May be a sign of injury to the ear, some disease process, or toxic leels of some medications from prolonged use.  
Serous Otitis Media   A collection of clear fluid in the middle ear that may follow acute otitis media or be due to an obstructioon of the eustachian tube.  
Audiometry   The process of measring how well an individual hears various frequencies of sound wavesa  
Presbycusis   Loss of hearing due to he natural aging process.  
Chalazion   A cyst or nodule on the eyelid resulting from an obstruction of a meibomian gland, which is responsible for lubricating the margin of the eyelid.  
Corneal Abrasion   A disruption of the cornea's surface epihelium commonly caused by an eyelash,small foreign body, contact lenses, or a scratch from a fingernail.  
Otoscopy   The use of an otoscope to view and examine the tympanic membrane and various parts of the outer ear.  
Meniere's Disease   Chronic inner ear disease in which there is an overaccumulation of endolymph (fluid in the labyrinth characterized by recurring episodes of dizziness (vertigo), hearing loss, feeling of pressure or fullness in the affected ear, and tinnitus).  
Acute Conjunctivitis   Inflammation of the mucous membrane lining theeyelids and covering the front part of the eyeball  
Diabetic Retiopathy   Occurs as a consequence of long term or poorly controlled dabetic mellitus in which the tissues of he retina experience scarring due abnormal dilation & constriction of vessels, hemorrhages, microaneurysm, abnorma formation of new vessels.  
Otosclerosis   A condition in which the footplate of the stapes becomes immobile and secured to the oval window, resulting in haring loss.  
Otoplasty   Removal of a portion of ear crtilage to bring the pinna and auricle nearer the head.
