In addition to testing a new drug that effectively stops such runaway vessel growth in mice, the team gave the drug a biodegradable coating to keep it in the eye longer. If proven effective in humans, the engineers say, it could mean only two or three needle sticks to the eye per year instead of the monthly injections that are the current standard of care...
