Management of a recurrent encapsulated bleb with a cost-effective non-valved glaucoma drainage device.

Despite the advancements in the surgical management of glaucoma, childhood glaucoma remains a challenging surgical disease worldwide. An early adolescent boy with primary congenital glaucoma, status after glaucoma drainage device (GDD) implantation, on maximum medical therapy, was presented with a swelling in the superotemporal orbital region. The patient had undergone an uneventful GDD implantation 2 years prior to presentation. A similar swelling, which was diagnosed to be a Tenon's cyst, had been excised on three earlier occasions. Given that the repeat capsular excision would also have the same likelihood of failure, and poor intraocular pressure control, a non-valved, cost-effective Aurolab aqueous drainage implant (AADI, Aurolab, Madurai, India) implantation was done inferonasally. In this patient, AADI proved to be a safe and effective alternative for the known GDDs.
