Microneedles Deliver Medications to the Eye

Microneedles Deliver Medications to the Eye
Nov-16-14
A microneedle method of delivering medication directly to the eye could offer a more efficient way to treat two of the world's leading eye diseases.

Delivering medication directly to the eye is a powerful way to treat eye diseases, but many people are understandably reluctant to have a needle come close to their eyes. And while eye drops are an option, their delivery is less than ideal and patient compliance is spotty.

The new drug delivery method, created by a team from Georgia Tech and Emory University, uses microneedles that will penetrate only to a certain depth and can target specific areas of the eye. The microneedle array would inject the medication into the area of the eye that produces the aqueous humor, and the specially-designed viscosity of the drug would ensure it remains in place near the injection site. The microneedle array could also be implanted in the eye to deliver a constant flow of medication, eliminating the need to apply daily eyedrops.
