Microneedles for Drug Delivery in Eyes
A researcher demonstrates the procedure
Researchers in the US have demonstrated for the first time that drugs can be successfully delivered to the eye using microneedles, potentially improving the treatment of diseases such as age-related macular degeneration (AMD).
The scientists – from the Georgia Institute of Technology and Emory University – used tiny microneedles less than 1mm in length to inject drugs into the suprachoroidal space of the eye, showing in animal studies that they could travel to the rear of the eye and deliver compounds to the retina and choroid.
