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.
