A new kind of eye drop holds out hope for even advanced cases of glaucoma.
It contains a protein called nerve growth factor, which helps
parts of the central nervous system damaged by disease or injury.
When Italian researchers gave it to three patients in their 60s and
70s, they showed improvements in visual sharpness and the ability
to detect contrast. Two of them had improved visual fields, while
the visual field stabilized for the third.
The researchers say the improvements remained even three months
after the treatments were finished. Dr. David Calkins of the Vanderbilt Eye Institute is guardedly optimistic about the new eye drops, but says more testing is needed.
The findings are in Tuesday's edition of Proceedings of the
National Academy of Science.
