If a client involved in a motor vehicle crash reports seeing flashes of light, the nurse should be prepared to address the detached retina. A detached retina is caused by vitreous traction on the retina. Glaucoma causes a person to see halos around lights. Scleroderma is a disease of the connective tissue, not the eye. Cerebral concussion does not result in this ocular symptom.
A detached retina occurs when the retina peels away or separates from its underlying layer of supporting tissue at the back of the eye. The retina is a thin layer of light-sensitive nerve cells. People need a healthy retina to be able to see clearly.
