Chapter 17a Procedures Flashcards
fluorescein angiography
intravenous injection of fluorescein (a dye) followed by serial photographs of the retina through dilated pupils
opthalmoscopy
visual examination of the interior of the eye
optical coherence tomography (OCT)
non-invasive imaging technique using light waves to take cross-sectional pictures of the retina
slit lamp microscopy
examination of anterior ocular structures under microscopic magnification
visual acuity test
clarity of vision is assessed
visual field test
measurement of entire scope of vision (peripheral and central)
enucleation
removal of the entire eyeball
keratoplasty
surgical repair of the cornea
laser photocoagulation
intense, precisely focused light beam (argon laser) creates an inflammatory reaction that seals retinal tears and leaky retinal blood vessels
LASIK
use of an excimer laser to correct errors of refraction (myopia, hyperopia, and astigmatism)
phacoemulsification
cataract removal surgery in which ultrasonic vibrations break up the lens–pieces are then aspirated through the ultrasonic probe
scleral buckle
suture of a silicone band to the sclera over a detached portion of the retina
vitrectomy
removal of the vitreus humor
