Implantation of an Alternative, Novel Glaucoma Drainage Device in the Treatment of Congenital Glaucoma Following Two Failed Filtration Surgeries

Abstract

Objective: To describe a novel glaucoma drainage device fashioned from a scleral buckle and nasolacrimal silicone tube. Method: This is a case report and a description of a surgical technique. Results: A 6-year-old boy with congenital glaucoma who underwent 2 failed filter surgeries had medically uncontrolled intraocular pressures (IOP). Due to limited funds for a second glaucoma drainage device, the author utilized a portion of a scleral buckle and nasolacrimal silicone tube – the same raw materials used in the Schocket implant – to fashion a novel, non-valved glaucoma shunt that was implanted in the patient’s eye. Postoperatively, IOP was 8-10mmHg. This was sustained for 12 months without the need for supplemental antiglaucoma medications. Postoperative complications included tube migration resulting in localized corneal decompensation and cataract formation. Conclusion: The alternative GDD made from a portion of a scleral buckle and silicone tube may be an effective and economical alternative to the GDDs available in the market.
