Researchers in Georgia, United States have pioneered a new technique that effectively delivers drugs to the eyes using microscopic needles. It could be a big boost for macular degeneration patients.
These new needles penetrate the eye only as deep as half a millimetre into the eye tissue. This means that they do not penetrate far enough to cause as much damage as traditional needles. As a result, they can be applied to the eye using only local anaesthetic.
Traditional delivery methods such as eye drops have difficulty in efficiently delivering drugs to the back of the eye, and ordinary injections are invasive as the needle penetrates across eye tissues. Repeated injections with regular needles can also result in other serious complications to vision.
