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. Post-operatively, IOP was 8-10mmHg. This was sustained for 12 months without the need for supplemental anti-glaucoma 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.
