Abstract

Tube retraction after Ahmed glaucoma valve (AGV) implantation is an infrequent but known complication. The management option includes the use of a commercially available AGV tube extender, 22 G angiocatheter, resisting the existing glaucoma drainage device (GDD), or insertion of a new GDD. Each of the methods described in the literature has its limitations. We describe the successful management of this complication by using a cost-effective technique of connecting the silicone tube segment to the existing tube to lengthen the tube, so that it could be inserted in the anterior chamber again. The silicone tubes used for the technique were the extra length of the GDD tube, which was cut short and leftover during other GDD implantation surgeries. Clinical significance: During any GDD implantation, the tube is cut short before entering the anterior chamber. We retrieved the short segments of the tube immediately after the GDD was opened on the table and sterilized them again using plasma technology, available in our operating room. Hence, it provides a cost-effective alternative since the tube is usually trimmed to the desired length in all cases of GDD implantation (valved/non-valved), which can be subsequently sterilized and reused for lengthening the short tube in cases with tube retraction or inadvertently cut tube.
