The black veil: Caring for patients with retinal detachments

GENERAL PURPOSE: To provide information about retinal detachments. LEARNING OBJECTIVES/OUTCOMES: After completing this continuing-education activity, you should be able to: 1. Recall the anatomy of the eye. 2. Explain the pathophysiology of retinal detachment. 3. Describe the management of retinal detachment.

  1. Retinal detachments occur when the inner layer of the retina separates from the
    1. ciliary body.
    2. choroid.
    3. retinal pigment epithelium.
  2. In the US, retinal detachments occur in approximately
    1. 1 in 5,000 individuals.
    2. 1 in 15,000 individuals.
    3. 1 in 35,000 individuals.
  3. The structure that initiates transmission of impulses to the optic nerve is the
    1. choroid.
    2. uvea.
    3. retina.
  4. The jelly-like substance in the center of the eye is the
    1. vitreous.
    2. aqueous humor.
    3. macula.
  5. The two areas composing the retina are the
    1. peripheral and night vision cones.
    2. macula and night vision rods.
    3. peripheral retina and macula.
  6. The sensitive structure that allows for perception of fine details is the
    1. cornea.
    2. macula.
    3. iris.
  7. When a retinal hole develops in one eye, the risk for the development of one in the other eye is
    1. less than 5%.
    2. 5% to 10%.
    3. 15% to 20%.
  8. Retinal tears occur when
    1. vitreous fluid gets under the retina, lifting it away from the underlying tissue.
    2. the vitreous shrinks and pulls on the retina.
    3. aqueous fluid solidifies, causing a bulge.
  9. The basic pathophysiology of a detached retina is that
    1. fluid accumulates under the retina.
    2. the retina hypertrophies.
    3. the retina atrophies.
  10. The vitreous is responsible for all of the following except
    1. controlling the amount of light entering the eye.
    2. aiding in refraction.
    3. maintaining the shape of the eyeball.
  11. Spots, circles, or irregular fine threads in an individual's vision are called
    1. scotomas.
    2. afferent pupillary defects.
    3. floaters.
  12. Risk factors for retinal detachment include all of the following except
    1. myopia.
    2. hypertension.
    3. lattice degeneration.
  13. Photopsia in retinal detachment manifests as
    1. floaters.
    2. irregular fine threads.
    3. flashes of light.
  14. Retinal holes are most often treated with
    1. vitrectomy.
    2. photocoagulation.
    3. cryopexy.
  15. Normal IOP ranges between
    1. 2 mm Hg and 8 mm Hg.
    2. 10 mm Hg and 21 mm Hg.
    3. 22 mm Hg and 30 mm Hg.
  16. The traditional surgical treatment for retinal detachment is
    1. pneumatic retinopexy.
    2. scleral buckle.
    3. photocoagulation.
  17. In pars plana vitrectomy, a gas bubble may replace the vitreous gel, which is ultimately
    1. absorbed and replaced by the body's own fluid.
    2. surgically removed and replaced with silicone oil.
    3. absorbed and then surgically replaced with a silicone scleral buckle.
  18. Postoperative patient discharge instructions should include
    1. no air travel for 1 year.
    2. no elevators over 10 floors for 3 months.
    3. no lifting of anything heavier than 10 lb for at least 1 week.
