Show Answers:

  1. Distance Visual Acuity
    • measure of the ability to see the details & shape of identifiable objects from a specified distance (usually 20 feet)
    • - typically uses a Snellen Chart
  2. Fluorescein Angiography
    visualization & photography of retinal & choroidal vessels made as fluorescein dye, which is injected into a vein, circulates through the eye
  3. Opthalmoscopy
    use of an opthalmoscope to visualize the interior of the eye
  4. Refraction
    measurement of refractive errors using a phoropter to determine best corrected vision prescription for eyeglasses or contact lenses
  5. Phoropter
    instrument that holds corrective lenses in front of the eye to determine optical correction
  6. Slit-Lamp Biomicroscopy
    use of a tabletop microscope to examine the eye, especially the cornea, lens, fluids, & membranes
  7. Sonography
    use of high-frequency sound waves to detect pathology within the eye such as foreign bodies or a detached retina
  8. Tonometry
    use of a tonometer to measure intraocular pressure, which is elevated in glaucoma
  9. Blepharoplasty
    • operative term
    • - surgical repair of an eyelid
  10. Cataract Extraction
    • operative term
    • - excision of a cloudy lens from the eye
  11. Cryoretinopexy, Cryopexy
    • operative term
    • - use of an intense cold to seal a hole or tear in the retina
    • - used to treat retinal detachment
  12. Dacrocystectomy
    • operative term
    • - excision of a lacrimal sac
  13. Enucleation
    • operative term
    • - excision of an eyeball
  14. Iridectomy
    • operative term
    • - excision of a portion of iris tissue
  15. Iridotomy
    • operative term
    • - incision into the iris (usually with a laser) to allow for drainage of aqueous humor from the posterior to anterior chamber
    • - used to treat a type of glaucoma
  16. Keratoplasty
    • operative term
    • - corneal transplant
    • - replacement of a diseased or scarred cornea with a healthy one from a matched donor
  17. Laser Surgery
    • operative term
    • - use of a laser to make incisions or destroy tissues
    • - uses: to create fluid passages, to obliterate tumors or aneurysms
  18. Laser-Assisted in Situ Keratomileusis (LASIK)
    • operative term
    • - technique using the excimer laser to reshape the surface of the cornea to correct refractive errors such as myopia, hyperopia, & astigmatism
    • - (smileusis- carving)
  19. Intraocular Lens Implant (IOL)
    • operative term
    • - implantation of an artificial lens to replace a defective natural lens
  20. Phacoemulsification
    • operative term
    • - use of ultrasound to shatter & break up a cataract with aspiration & removal
  21. Scleral Buckling
    • operative term
    • - surgery to treat retinal detachment by placing a band of silicone around the sclera to cinch it toward the middle of the eye & relieve pull on the retina
    • - often combined with other techniques to seal retinal tears such as cryoretinopexy
  22. Trabeculectomy
    • operative term
    • - removal of a portion of the trabecular meshwork to increase the flow of aqueous humor from the eye
    • - used to treat: acute glaucoma or glaucoma not treatable with medication
  23. Contact Lens
    • therapeutic term
    • - small plastic curved disk with optical correction that fits over the cornea
    • - used to correct refractive errors
  24. Eye Instillation
    • therapeutic term
    • - introduction of a medicated solution in the eye
  25. Eye Irrigation
    • therapeutic term
    • - washing of the eye with water or other fluid
  26. Antibiotic Opthalmic Solition
    • drug classification
    • - antimicrobial agent in solution
    • - use: to treat bacterial infections (ie, conjunctivitis, corneal ulcers)
  27. Cycloplegic
    • drug classification
    • - agent that paralyzes the ciliary muscle & powers of accommodation
    • - use: pediatric eye exams
  28. Mydriatic (dilation of pupil)
    • drug calssification
    • - agent that causes dilation of the pupil (for certain eye exams)
  29. Miotic

    • - (mio= less)
  30. IOL
    intraocular lens
  31. LASIK
    laser-assisted in situ keratomileusis
