Oven cleaner offers glaucoma hope

The active ingredient finds it hard to penetrate the eye
A substance found in oven cleaner could be used to treat the eye disease glaucoma, US research suggests.
Cerium oxide nanoparticles, also commonly used in window cleaner, may help in more effectively delivering an active ingredient into the eye.
According to details published in the New Scientist, the substance did not irritate the eye when it was tested on both rats and rabbits.
Experts said proper trials were needed before any real claims could be made.
But they did stress that a more effective way of delivering medicine would be welcomed.
