A small study conducted by researchers at 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 was published in the journal Ophthalmology. The research included 20 patients who had surgery for Terson syndrome, a specific type of hemorrhage caused mostly by traumatic injury, such as vehicular collisions. Some of the patients experienced this hemorrhaging in both eyes, thus allowing for the study of 28 eyes.
The procedure used to restore sight in these patients is known as a vitrectomy. The surgery removes the jellylike tissue behind the lens of the eye and replaces it with a saline solution. The patients were split into groups who had the surgery within three months of the hemorrhage and those who received it after the three month mark.
