Background and Objectives: Glaucoma drainage devices have been widely used in management of complicated glaucoma. More incidence of complications of the devices have been reported. The aim of this study was to report a case with extrusion of glaucoma drainage device tube from anterior chamber and to present the surgical correction by excision of the tube.
Methods: Report a case of extrusion of glaucoma drainage device tube from the anterior chamber and review literatures.
Results: A 58-year-old male diagnosed with advanced glaucoma underwent glaucoma drainage device in the right eye 2 years ago. The extrusion of glaucoma drainage device tube from anterior chamber had been noted and no sign of infection was detected. The patient underwent tube excision and was followed for further exposure at 2 and 6 weeks. There was no tube exposure and sign of infection at 2 weeks. Unfortunately, there was minimal tube exposure at 6 weeks follow-up, but no sign of infection was detected but tube was further exposure at 12 weeks post-operation so the patient underwent second operation for tube excision with more lengthening than the first operation to made tube contraction under scleral patch graft covering. Scleral patch graft was suture fixed to patient’s sclera for prevention of re-exposure. The result of second operation at 1, 2 and 4 weeks follow-up was no re-exposure and sign of infection.
Conclusions: Exposed glaucoma drainage device tube with no sign of infection can be immediately treatment not only medications but also surgical revision to prevent infection. This report shows alternative management of exposed tube by excision of exposed tube and surgical technique to solve the cause of re-extrusion. However, additional studies are required to determine the proper management.
