Surgeons in Britain are pioneering a new technique that uses radiation beams as wide as a pinpoint to kill off abnormal blood vessels found at the back of eyes of those with blindness caused by macular degeneration. This technique will come as good new to patients who currently have to monthly injections which cost £800 a time. The new procedure is estimated to cost £6000, and should be cost effective after 7 months. Early signs are that the radiation does not harm other healthy cells in the eye as the radiation probe would point specifically to the area of damage.
