Senses Procedures
Question | Answer |
---|---|
Audiometry | The graphic record drawn from the results of hearing tests with the audiometer; charts the threshold of hearing at various frequencies against sound intensity in decibels |
Electrocochleography | A measurement of the electrical potentials generated in the inner ear as a result of sound stimulation |
Electronystagmography | electrooculography; skin electrodes are placed at outer canthi to register horizontal nystagmus, or above and below each eye for vertical nystagmus |
Electroretinography | A record of the retinal action currents produced in the retina by an adequate light stimulus |
Fluorescein | an orange-red crystalline powder that yields a bright green fluorescence in solution; a nontoxic,water-soluble indicator used diagnostically to trace water flow and to visualize corneal abrasions or ulcers |
Gonioscope | A lens designed to study the angle of the anterior chamber of the eye |
Ophthalmoscope | An instrument for examining the inner eye chambers and the retina |
Optometer | An instrument for determining the refraction of the eye |
Optomyometer | An instrument for determining the relative power of the extrinsic muscles of the eye |
Otoscope | An instrument for examining the drum membrane or auscultating the ear |
Slit lamp | an instrument consisting of a microscope combined with a rectangular light source that can be narrowed into a narrow beam for examination of anterior segments of the eye |
Tonometry | Measurement of ocular tension |
Tympanogram | A visual depiction (e.g., a printout) of the relative compliance and impedance of the structures of the middle ear in response to pressure changes in the external ear canal |
Iridotomy | Creating a hole in the iris to prevent or treat angle closure glaucoma |
Laser photocoagulation | A method by which a beam of electromagnetic energy is directed to a desired tissue under visual control localized coagulation results from absorption of light energy |
Mastoidectomy | Hollowing out of the mastoid process by curretting, gouging, drilling, or otherwise removing the bony partitions forming the mastoid cells |
Myringotomy | Paracentesis of the tympanic membrane |
Optic keratoplasty | Transplantation of transparent corneal tissue to replace a leukoma or scar that impairs vision |
Phacoemulsification | A method of emulsifying and aspirating a cataract with a low-frequency ultrasonic needle |
Radial keratotomy | A radial incision operation making a partial thickness incision into the cornea to flatten it and reduce its refractive power in that meridian. |
Refractive surgery | Surgical procedure to detect an error of refraction and to correct it by means of lenses |
Scleroplasty | Surgical molding or reshaping of the sclera |
Stapedectomy | Operation to remove the stapes footplate in whole or part with replacement of the stapes superstructure (crura) by metal or plastic prosthesis; used for otosclerosis with stapes fixation to overcome a conductive hearing loss |
Tympanoplasty | Operative correction of a damaged middle ear |
Vitrectomy | Removal of the vitreous by means of an instrument that simultaneously removes vitreous by suction and cutting and replaces it with saline or some other fluid |
