Restoring eye vision is one of the few things that the scientists and researchers have been studying since a long time. Recently few researchers through a surgery have managed to restore normal 20/20 vision in patients who have lost their vision due to a traumatic brain injury.
The CDC has estimated that around 2.5 million emergency room visits or deaths were caused due to the traumatic brain injury in the United States in 2010 alone. This kind of brain injury causes severe damage to patient’s vision and might even lead to blindness. Such being the intensity of this issue, the recent discovery made by the researcher is best that can be done.
The study was performed by researchers from Washington University School of Medicine in St. Louis, the Kresge Eye Institute at Wayne State University in Detroit, and the L.V. Prasad Eye Institute in India. The study is published in the journal, Ophthalmology.
The research included 20 patients who have undergone the surgery for Terson syndrome. The syndrome is a particular type of hemorrhage mainly caused due to traumatic injury, like vehicular collisions. The study was performed on 28 eyes as few of them had both their eyes affected due to the injury.
The process of restoring the vision to such patients is referred to as vitrectomy. The surgery mainly removed jelly like structure behind the lens of the eye and replaced it with saline solution.
Patients were divided into two groups so as to analyse the outcome of the study in an accurate way. The patients who received the surgery within three months of the hemorrhage were differentiated from those who have who received it after the three-month mark.
One month after the surgery has been performed, Patient’s vision has improved to an average of 20/40 from an average of 20/1290. All patients regained normal 20/20 vision as months followed.
Researchers have concluded that duration of time between the injury and surgery time did not factor into the recovery of patient’s vision. Moreover, the researchers were able to restore vision to those patients who were blind before the injury.
Rajendra S. Apte, MD, Ph.D., the Paul A. Cibis Distinguished Professor of Ophthalmology and Visual Sciences at Washington University School of Medicine stated, “It was important to learn how long we could wait to operate without having a negative effect on vision.”
