A 56-year-old woman with a history of trabeculectomy in both eyes sustained blunt trauma to the right eye at home. She initially presented with pain, loss of vision, total hyphema, and hypotony with no evidence of rupture or tissue prolapse. Prompt anterior chamber wash out revealed a partially subluxated crystalline lens behind the pupil, but the globe was intact. At 1 month postoperatively, subconjunctival displacement of the crystalline lens was detected. The patient gave a history of severe bouts of coughing and sneezing a few days earlier. During removal of phacocele, the trabeculectomy wound was intact with no evidence of leakage. A shallow concentric furrow was noticed across the flap approximately 3 mm from the limbus. It is believed that repeat trauma pushed the crystalline lens through the weakened trabeculectomy scleral flap. The wound later self-sealed.
一名56岁女性，双眼曾行小梁切除术，在家中右眼遭受钝挫伤。她最初表现为疼痛、视力丧失、全前房积血和低眼压，无破裂或组织脱垂迹象。及时进行前房冲洗发现瞳孔后有部分半脱位的晶状体，但眼球完整。术后1个月，检测到晶状体结膜下移位。患者几天前有严重咳嗽和打喷嚏发作史。在摘除晶状体膨出物时，小梁切除术伤口完整，无渗漏迹象。在距角膜缘约3毫米处的瓣上发现一条浅同心沟。据信，反复创伤使晶状体穿过薄弱的小梁切除术巩膜瓣。伤口后来自行愈合。
