Refer to the article "The black veil: Caring for patients with retinal detachments", Nursing2019, September, Vol. 49, No.9, p. 35-40 to answer the following questions. Your answers must be TYPED (your answers may not be hand-written). (This article can be accessed via Blackboard - go to Resource folder in the Special Senses tab.)
1. The jelly-like substance in the center of the eye is the:
- vitreous.
- aqueous humor.
- macula.
- choroid.
2. The basic pathophysiology of a detached retina is that:
- fluid accumulates under the retina.
- the retina hypertrophies.
- the retina atrophies.
- all of the above are true.
3. Photopsia in retinal detachment manifests as:
- floaters.
- irregular fine threads.
- flashes of light.
- all of the above.
4. The structure that initiates transmission of impulses to the optic nerve is the:
- choroid.
- uvea.
- iris.
- retina.
5. The vitreous is responsible for all of the following except:
- controlling the amount of light entering the eye.
- aiding in refraction.
- maintaining the shape of the eyeball.
- filling the entire space posterior to the lens.
6. The sensitive structure that allows for perception of fine details is the:
- cornea.
- macula.
- iris.
- peripheral retina.
7. In pars plana vitrectomy, a gas bubble may replace the vitreous gel, which is ultimately:
- absorbed and replaced by the body's own fluid.
- surgically removed and replaced with silicone oil.
- absorbed and then surgically replaced with a silicone scleral buckle.
- none of these are true.
8. Retinal holes are most often treated with:
- photocoagulation.
- vitrectomy.
- cryopexy.
- no treatment is commonly necessary.
