Abstract:
Objective: Our aims were to find a new aqueous drainage device-umbilical artery tube (UAT) and to study its effect in decreasing IOP. Methods:UAT is acquired from the newborn infants umbilical cord that has been disposed by 0.5% glutaraldehyde solution. As an device, UAT is required that its inner diameter is 1.0 mm and the outer one varies from l.5 mm to 2.0 mm. There are totally 12 cases, among them, 10 cases underwent aqueous drainage implantation in anterior chamber, 2 cases underwent in vitreous and cooperated with vitreous incise surgery. The mean follow-up period was 2 years and 3 months. Results: The average IOP was 7.8 kPa before operation and was 2.5 kPa during follow-up period. The success rate was 67.9%. Seven cases were no more than 2.8 kPa . One case was 2.7 kPa after using 0.5%Timolol. Complication：one case hemorrhaged in anterior chamber, 2 cases had shallow anterior chamber. There was no severe complication, such as sclera solve or necrosis, UTA exposing or being rejected.Conclusion: UTA implantation is effective in the management of refractory Glaucoma.
