A new treatment could offer a solution for people who suffer from glaucoma. The treatment involves inserting a tiny iStent implant at the base of the iris. It works by allowing fluid to escape and thus relieving the pressure. Patient Mary McCall has become the first British patient to undergo the procedure on one eye which appears to have been successful, she will later have the other eye treated. Glaucoma is a progressive illness which is caused when the optic nerve is damaged by a build up of fluid. Although it can often be controlled with drops patients start to lose their peripheral vision and can go blind. The iStent procedure, however, stops the progression of glaucoma and could save the eyesight of many people.
