Report three different solutions in case of XEN-augmented Baerveldt fails.
Drainage devices have been used for refractory pediatric glaucoma. To avoid early hypotony and corneal damage, Mermoud et al. introduced the augmentation of a XEN implant with a Baerveldt tube. In some cases, this technique fails to lead to a high intraocular pressure (IOP) and surgical revision.
Three cases of children with this combined implant needed surgical revision due to high IOP. Three different approaches were performed: XEN replacement in one case, stretching the Baerveldt's tube into the anterior chamber (AC) in the second case, and explant of the device followed by an implant of a new Baerveldt-250 in the same quadrant in the third case. Successful control of IOP (>18 mm Hg) was achieved in all patients under no topical treatment.
Despite the attractiveness of the XEN-augmented Baerveldt implant in refractory pediatric glaucoma as an alternative to conventional surgery, we have to learn how to deal with failures. Three different approaches are presented with good short-term results. The long-term efficacy is yet to be assessed.
Describe three possible options when faced with a need for surgical revision in XEN-augmented Baerveldt implant.

报告XEN增强型Baerveldt植入物失败时的三种不同解决方案。
引流装置已用于难治性儿童青光眼。为避免早期低眼压和角膜损伤，Mermoud等人引入了用Baerveldt管增强XEN植入物的方法。在某些情况下，该技术未能导致高眼压和手术翻修。
三例使用这种联合植入物的儿童因高眼压需要进行手术翻修。采用了三种不同的方法：一例更换XEN，第二例将Baerveldt管延伸至前房，第三例取出装置并在同一象限植入新的Baerveldt-250。所有患者在未进行局部治疗的情况下眼压均成功控制在>18 mmHg。
尽管XEN增强型Baerveldt植入物作为传统手术的替代方案在难治性儿童青光眼中具有吸引力，但我们必须学会如何应对失败情况。本文介绍了三种不同的方法，短期效果良好。长期疗效尚待评估。
