Abstract:
We describe a technique of sub-Tenon's drug administration involving the use of a strip of collagen sponge connected with a silicone tube. The strip is implanted in the sub-Tenon's space and the free end of the tube is attached to the patient's forehead. Medication is infused through the tube two to four times a day for 7 to 10 days; then the tube is removed. We have used this technique, without serious complications, in the treatment of 230 patients with various diseases of the posterior segment and the anterior part of the optic nerve.
