Language of Medicine Chapter 17 - Clinical Procedures

Chabner's Language of Medicine, 9th edition. Clinical Procedures for Chapter 17- sense organs.
flourescein angiography
intravenous injection of flourescein (dye) followed by serial photographs of the retina through dilated pupils
visual examination of the interior of the eye
slit lamp microscopy
examination of the anterior oculart structures under microscopic magnification
visual acuity test
clarity of vision is assessed with Snellen chart at 20 ft.
visual field test
Measurement of the area (peripheral and central) within which objects are seen when the eyes are fixed, looking straight ahead without movement of the head
removal of the entire eyeball
surgival repair of the cornea (corneal transplant)
laser photocoagulation
intense, precisely focused light beam (argon laser) creates an inflammatory reaction that seals retinal tears and leaky retinal blood vessels
use of an excimer laser to correct errors of refraction (myopia, hyperopia, amd astigmatism)
ultrasonic vibrations break up the lens, which then is aspirated through the ultrasonic probe
scleral buckle
Suture of a silicone band to the sclera over a detached portion of the retina
removal of the vitreous humor
testing the sense of hearing
cochlear implant procedure
surgical insertion of a device that allows sensorineural hearing-impaired persons to understand speech
ear thermometry
measurement of the temperature of the tympanic membrane by detection of infrared radiation from the eardrum
visual examination of the ear canal with an otoscope
tuning fork test
test of ear conduction using a vibration source (tuning fork)
Means of diagnosing glaucoma; an instrument is applied externally to the eye after administration of local anestheticto measure intraocular pressure
Rinne test
A test of ear conduction in which the base of the vibrating tuning fork is placed against the mastoid bone (bone conduction) and in front of the auditory meatus (air conduction)
Weber test
A test of ear conduction in which the tuning fork is placed on the center of the forehead
