Arteritis
 
Arterial inflammation
Hyperopia
 
Farsightedness
Hypertrophied
 
Enlarged
Myopia
 
Nearsightedness
Amblyopia
 
Reduced vision on an eye - no obvious reason
Anklosis
 
Immobility of a joint
Audiogram
 
Record of hearing test
Diplopia
 
Double vision
Hitoplasmosis
 
Systemic respiratory disease caused by a fungus
Laser Photocoagulation
 
Coagulation of blood vessels in eye by laser
Macula
 
Small spot of colored area
Photophobia
 
Sensitivity to light
Purulent
 
Containing pus
Seborrhea
 
Excessive secretion of sebum from sebaceous glands
Tonometry
 
Measeurement of intraocular pressure
Toxoplasmosis
 
disease from protozoa from mammals and birds
Layers of eye
 
Sclera, choroids, retina
Colorless, transparent portion of eye
 
Cornea
Classifications of hearing loss
 
Conductive and senorineural
Symptoms Otosclerosis
 
Gradual hearing loss of low/soft sounds, tinnitis
Canal that connects middel ear with nasopharynx
 
Eustachian Tube
Shape of eyeball
 
Spherical
Structure that maintains balance
 
Labyrinth
Sensory receptors in retina that detect color and refinement
 
Cones
Earwax
 
Cerumen
Jellylike substance in orb
 
Vitreous Humor
Internal elastic disc that focuses images, near and far
 
Lens
Cause of Cholesteatoma
 
Estauchian tube fails to open blocking tube which fills with stuff from recurring ear infections. Tube develops weak pocket, skin cells collect.
Short eyeball
 
Hyperopia
Long eyeball
 
Myopia
Cause astigmatism
 
Nonshperical cornea
Symptoms refractive errors
 
Blurred vision, fatigue
Most common nystagmus
 
Congenital
Bacteria responsible for styesD
 
Staphylococci
Symptoms Keraitits
 
Decreased vision, irritaion, tearing, photophobia, redness of conjunctiva
Cuase Cataracts
 
Opacification of lens - aging process
Cure for Macular Degeneration
 
No
Retinal blood vessels in a diabetic
 
Diabetic Retinopathy
Causes for ruptured eardrums
 
Sharp objects, explosion, infection, blow to ear.
Portion that regulates light to eyeD
 
Iris, colored portion
Four major refractive errors
 
Hyperopis, Myopia, Astignatism, Presbyopia
Strabismus
 
Failure of the eyes to look in the same direction, weakness in nerve impluse failing to control muscles
Esotropia
 
Inward turning of eyes, crosseyed
Exotropia
 
Outward turing of eyes
Nonulcerative blepharitis
 
Exposure to dust, smoke, chemicals
Symptoms Stye
 
Pain, swelling, redness
Cause Keratitis
 
Herpes Simplex
Blepharitis
 
inflamation of the margins of the eyelids, scondary to seborrhea,
BlepharoptosisD
 
{tpsos. drooping eyelid, age related, familiar and can obstruct vision
Cause Conjunctivitis
 
Bacterial or viral
Corneal Abrasion
 
Painful loss of epithelium or outer layer of cornea
Symptoms of ear disease requiring medical attention
 
Hearing loss, pain, pressure, tinnitus, vomiting
Most common ailment of children
 
Otits Media
Treatment Blepharitis
 
Antibiotic Opthalmic oint.
Treatment Bacterial conjunctivitis
 
Topical Antibiotic
Treatment Glaucoma
 
Betaxolol, timolol, latanoprost
Use of prescribed meds for open angle glaucoma
 
Use on regular basis, don't miss doses
Meds used for Macular degeneration
 
Vitamins A, C, E, Zinc
Treatment Otits Media
 
Ibuprofen, pseudoephedrine, sulfamethoxazole
Treatment Meniere's Disesase
 
Meclizine (antivert)
Otosclerosis
 
Ankylosing of the stapes
Labyrinthitis
 
Inflamation of the semicircular canal
Conductive hearing loss - causes
 
Cerumen impaction, otitis media, otosclerosis
Most common cause of blindness in US
 
Macular degeneration
Process of vision
 
Light through lens, impact retina, rods/cones stimulated, nerve impluses sent to brain by optic nerve.
Nystagmus
 
Repetitve/involuntary movement of one/both eyes from abnormality of retina, congenital defects, pathologic anomalyin brain or drugs
Strabismus
 
Failure of eyes to look in same direction, muscel/nerve failure, other disease processes
Hordeolum
 
Stye
Symptoms Conjunctivitis
 
Redness, swelling, itching, tearing, light sensitivity. Purulent discharge. Highly contacgious.
How do cataracts obstruct sight
 
Cloudy/opaque lens obstructs light
Diabetic Retinopathy
 
Microaneurysm, hemorrhages, dilation of retinal veins, neovascularization.
Treatment Diabetic Retinopathy
 
Laser photocoagulation and vitrectomy
Open Angle Glaucoma
 
Blockage of travecular meshwork that impairs aqueous humor reabsorption, gradual elevation of IOP
Closed Angel Glaucoma
 
Blockage in the drainage system of the eye, acute elevation in IOP
Retinal Detachment
 
Opthalmic exam detects retina tear - partial to total loss of sight.
Causes Exophthalmos
 
Enlarged Intraocular muscles, retrobulbar mass, edema of soft tissue. Hyperthyroid, hypthyroid, euthyroid (normal thyroid) stare, hemorrhage, inflammation
Cancer's effect on eye structures
 
Bone of orbit, soft tissues muscles between globe and bone, optic nerve eyeball itself
Sturctures of ear
 
Outer auditory cannal and auricle, middle ear: tympanic membrane, three ossicles, ET, oval window, inner ear: cochlea, labyrinth, vestibulocochlear nerve
Myringotomy
 
Surgical incision into ear drum to relieve pressure, provide drainage, allow middle ear to fill with air
Meniere's disease
 
Vertigo, tinnitus, progressive hearing loss, sensation of fullness in ears, N/V, loss of balance
Major Symptom of Labyrinthitis
 
Vertigo
