Doctors claim to have carried out a ground-breaking operation to help a patient regain sight in his one eye which was left blind after being hit by a stone nearly 55 years back.
A team at the New York Eye and Ear Infirmary,which carried out the surgery to re-attach the mans retina,said it is the first time that a patient with a long-term detached retina has seen such an improvement after operation.
The 63-year-old unnamed patient was left completely blind in his right eye after an accident in th 1950s when he was just eight years old. Last year,he entered the Infirmary complaining of persistent pain and redness in the eye.
Doctors found he had glaucoma and high eye pressure. After treating the eye pressure and,using a technique called monoclonal antibody therapy,treating the glaucoma,he told them that he could perceive light again.
Encouraged,the doctors performed an operation to re-attach the retina. Subsequently,the man had recovered his sight to such an extent that he could count fingers more than 15 feet,The Daily Telegraph reported.
When a retina has been detached for so long,degenerative changes usually occur that make restoring sight impossible. Dr Olusola Olawoye of the infirmary said: The incident is published in the Journal of Medical Case Reports.
