CLINICAL CASE: The case concerns a 78 year-old woman with a history of XEN surgery, in whom a conjunctival perforation was observed at the implant level at 18-months of follow-up, for which surgical intervention was decided. During surgery a short subconjunctival portion was found (0.5mm). An unsuccessful attempt was made to extract it by traction, but the XEN broke easily. Finally, it was decided to cut it to scleral level, and suture the conjunctiva. During the first week there was a decrease in intraocular pressure (6mmHg), to subsequently increase to 25, and deciding to start medical treatment. DISCUSSION: Conjunctival exposure of the XEN stent is a rare but potentially serious complication. To avoid it, a meticulous surgical technique is important when implanting it. If this occurs, it is important to identify the cause. If it is due to a short subconjunctival portion, a therapeutic alternative is to cut the implant at this level to avoid further complications.
