spinal tap
describe SNELLEN CHART (SC)
measure visual acuity as fraction; 1st/top # is standard distance (20 ft) & 2nd/bottom # is deviation from normal

determine eye's refractive error to find best corrective lenses; refers to ability of lens to bend light rays to focus
define DIOPTER
unit of measurement of lens' refractive power
define COVER TEST
examine binocular vision
describe VISUAL FIELD TESTING
indicate whether object/light seen in peripheral to determine loss in peripheral vision; a blank section indicated glaucoma/optic nerve disorder
aka: visual field testing
perimetry
define OPHTHALMOSCOPY
visually examine fundus (retina, optic disk, choroid, & vessels)
aka: ophthalmoscopy
fundoscopy

prep for ophthalmoscope exam using mydriatic drops to artificially enlarge pupils
define MYDRIATIC DROPS
temporary paralysis of pupils
define SLIT-LAMP MICROSCOPY
narrow beam of light focused on parts of eye to examine anterior structure thru magnification
define OPHTHALMOSCOPY
examine @ front of eye (cornea/iris/lens) & interior
define FLUORESCEIN STAINING
detect foreign bodies, infection, & injury using drops/strip applicator
describe FLUORESCEIN ANGIOGRAPHY (FA)
photographic study of blood vessels @ back of eye w/contrast & xrays to determine proper circulation throughout retina & look for disease
describe PUPILS ARE EQUAL, ROUND, REACTIVE TO LIGHT, & ACCOMODATION (PERRLA)
diagnostic observation; abnormality indicates brain damage or head injury
describe TONOMETRY
measurement of IOP; abnormally high indicates glaucoma
define AUDIOMETRY
use audiometer to measure hearing acuity
define AUDIOLOGICAL EVALUATION
measure ability to hear & understand speech based on pitch & volume
aka: audiological evaluation
speech audiometry
define OTOSCOPE
instrument to examine external ear canal
define MONAURAL TESTING
involves 1 ear
define BINAURAL TESTING
involves both ears
describe TYMPANOMETRY
air pressure in ear canal to test for middle ear disorders by testing for middle ear fluid buildup, eustachian tube obstruction, & conducting hearing loss
define ACOUSTIC REFLECTOMETRY
measures how much sound reflected from eardrum by testing amount of fluid in middle ear to diagnose otitis media
