Eyesight is one of life’s most precious and delicate gifts. As per the Center for Disease Control and Prevention, in 2010, 2.5 million emergency room visits or deaths were associated with traumatic brain injury in the United States alone, which leads to severe damage to a patient’s vision, and even blindness in many cases.
Researchers at Washington University School of Medicine in St. Louis and the L.V. Prasad Eye Institute in India have made a big breakthrough in technology which can help reverse blindness caused by a traumatic brain injury even to levels of perfect vision.
Reversing Blindness After Trauma
Researchers studied 20 patients who experienced hemorrhaging in the eyes caused by traumatic injury. Most of the patients who could not even detect a hand waved in front of their faces before surgery had 20/20 vision after surgery.
The special procedure used is known as a vitrectomy. It involves removing the jellylike tissue behind the lens of the eye and replacing it with a saline solution.
Prior to the surgeries, the average vision in patients was 20/1290. Within one month of surgery, the average was 20/40. A few months later, almost all patients had 20/20 vision.
