AN INJECTION may replace the need for daily drops or surgery for those with glaucoma, a leading cause of blindness.
The condition is caused by a blockage in the main drainage channel from the eye, which leads to a build-up of fluid. This results in increased pressure that damages the optic nerve.
Drops or implanted devices can help, but they don’t work for all. The jab contains hydrogel, a water-absorbing chemical compound, which props open another channel in the eye to drain the fluid.
Scientists at the Georgia Research Alliance in the US, writing in the journal Advanced Science, said the jab helped reduce the pressure for four months. They are working on ways to extend the effects.
