In another presentation, Jules Baum, MD, professor, Department of Ophthalmology, Tufts University School of Medicine/New England Medical Center, Boston, described a method of getting medication into the vitreous that he believes is a vast improvement over common intravitreal injection.Baum’s collaborator, David Maurice, PhD, conceived of the idea of using iontophoresis to get antibiotics into the vitreous while he was riding a number-64 bus through the streets of London, in 1965. However, it wasn’t until recently that Maurice, professor of ophthalmology and physiology at Stanford University School of Medicine, working in collaboration with Baum, actually began designing the apparatus and experimenting on rabbits.
Iontophoresis is the use of an electrical current to enhance the penetration of charged solutes into the tissues of the body. The technique is not new to ophthalmology, having been used for some corneal diseases, but it is rarely if ever used today, largely because more potent drugs are available for treating those conditions, Baum says.

But, while getting drugs into the cornea is relatively easy, getting effective levels of drugs into the retina or vitreous of the eye has been difficult. Drops or other topical modalities do not penetrate sufficiently to attain thera-putic levels in the vitreous.
