Here is good news for people who figured in untoward accidents leading to brain injury and subsequent vision problems. Science has made restoration of perfect vision a not-so-remote possibility anymore.
A study, published in the journal Ophthalmology, revealed that a surgical method called vitrectomy can lead to a rapid visual recovery of individuals grappling with traumatic brain injury (such as those caused by vehicular accidents) or were legally blind before an injury. Improvements in instrumentation and technologies have reduced surgical risks and improved visual outcomes.
Surveyed were 20 patients who underwent surgery to treat Terson Syndrome. This condition is known as intraocular hemorrhage associated with intracerebral hemorrhage, severe headache & bleeding resulting from a head injury, or traumatic brain injury.
The Study Details
Because some of the patients had the hemorrhage in both eyes, a total of 28 eyes were studied. Approval for the conduct of the study was obtained from the institutional review board of three participating centers: the L.V. Prasad Eye Institute in Hyderabad, India; Kresge Eye Institute, Wayne State University, Detroit, Michigan; and Washington University Eye Center, St. Louis, Missouri.
What the researchers did with the 20 patients was remove the jellylike tissue behind the lens of the eye. They then replaced it with a saline solution. The visual outcome was quite positive. A month after the surgery, the vision of patients improved at an average of 20/40. After a few months, almost all patients had 20/20 vision.
Vitrectomy was introduced more than 40 years ago, but science has led to greater ease and safety for patients. Improved surgical techniques through the years have lessened vitrectomy-related complications ranging from having no improvement in vision to permanent vision loss.
Given the rising cases of traumatic brain injuries that cause severe damage to, and impair, a person’s vision, scientific breakthroughs and medical procedures can spell great relief. It appears like a cure for blindness is in sight.
