Eye & ear diagnostic tests/procedures Flashcards
Detailed measurement of hearing with an audiometer
Audiometry:
Surgical insertion into the cochlea of a device that receives sound and transmits signals to electrodes implanted within the cochlea, allowing hearing-impaired persons to perceive sound
Cochlear implant:
Use of multicolored charts to evaluate the patient’s ability to recognize color
color vision tests:
Surgical replacement of a diseased cornea with a healthy one from a donor
Corneal transplant (keratoplasty):
Surgical removal of the entire eyeball
Enucleation:
Procedure in which a laser is used to alter the shape of the deep corneal layer after a top flap in the surface is opened
Laser-assisted in-situ keratomileusis (LASIK):
Destruction of areas of the retina with a laser beam
Laser photocoagulation:
Removal of the lens with an ultrasonic device to treat cataracts
Phacoemulsification:
Incision into the outer portion of the cornea to flatten it and help correct nearsightedness
Radial keratotomy:
Evaluation of the eye’s ability to focus an image
Refractive error test:
Hearing test that compares bone conduction with air conduction, using a tuning fork
Rinne test:
Placement of a band of silicone around the eyeball to stabilize a detaching retina
Scleral buckling:
Examination of the posterior surface of the cornea with a slit lamp
Slit-lamp microscopy:
Measurement of intraocular tension to detect glaucoma
Tonometry:
Procedure for evaluation of the mobility and patency of the eardrum, detection of middle-ear disorders, and evaluation of the patency of the eustachian tube
Tympanometry:
