She hit her head on the headrest and windshield. Initially, Kathy showed no signs of significant injury. The condition was constant and affected Kathy's ability to use her computer at work. Her night vision was also adversely affected. He explained that floaters occur when the liquid center of the eye, known as the vitreous humor, becomes detached from the back of the eye.
Pockets then form at the back of the eye, which trap debris.
The tiny debris then project shadows on the back of the eye which appear as floaters. Washburn testified he saw no floaters in a pre-accident eye examination of Kathy conducted on April 5, 1993. He also noted that Kathy was not complaining about any floaters prior to the accident. Dr. Washburn's opinion, based upon reasonable medical probability, was that the floaters could have been caused by the head trauma from the car accident. However, he also acknowledged that floaters can spontaneously occur as a normal part of the aging process.
