MIRAgel (MIRA, Waltham, MA) scleral buckle material was initially developed in the 1980s as an alternative to more traditional silicone buckles. Long-term follow-up has demonstrated complications necessitating removal due to unanticipated hydrolytic degeneration of the exoplant. Material expansion and fragmentation have led to pain, limited extraocular motility, ocular masses, infection, and eventual extrusion. Complications occur later than in other materials; most patients need removal an average of 7 years to 13 years after implantation. This case describes a previously not reported case of MIRAgel scleral buckle extrusion complicated by preseptal cellulitis and complete erosion of the material through the inferior eyelid and extrusion through the skin.

MIRAgel(MIRA,马萨诸塞州沃尔瑟姆)巩膜扣带材料最初于20世纪80年代开发,作为更传统硅酮扣带的替代品。长期随访显示,由于外植体意外的水解变性,出现了需要取出的并发症。材料膨胀和破碎导致疼痛、眼球运动受限、眼部肿物、感染以及最终的挤出。并发症比其他材料出现得晚;大多数患者在植入后平均7年至13年需要取出。本病例描述了一例此前未报道的MIRAgel巩膜扣带挤出病例,该病例并发眶隔前蜂窝织炎,材料完全侵蚀下眼睑并通过皮肤挤出。[《眼科手术、激光与视网膜成像》。2016年;47:1147 - 1150。]
