[A new method of drug administration into the posterior section of the sub-Tenon's space]

A new method for instillation and deposition of drugs in the sub-Tenon's space has been developed, that permits the maintenance of a high concentration of the drug directly in contact with the posterior segment sclera and membranes of the optic nerve anterior segment. It consists in the following: a collagen hemostatic sponge, connected to a silicone tube, is implanted into the sub-Tenon's space; the drugs are administered via this tube. Analysis of the results of 115 surgeries has demonstrated considerable advantages of this method over the traditional methods of drug instillation.
