To report a case of epithelial ingrowth (downgrowth) occurring in a phakic corneal transplant patient after traumatic wound dehiscence with iris prolapse that was successfully eradicated with early surgical intervention.
Interventional case report of a 70-year-old monocular, phakic patient who developed epithelial ingrowth within 1 week of repair of a traumatic penetrating keratoplasty wound dehiscence, with reposition of the iris that had been prolapsed for 36 hours. A gradually expanding membrane developed from the surface of the reposited iris, across the anterior lens capsule. Argon laser photocoagulation applied to the surface of the iris confirmed the diagnosis and outlined the extent of the epithelial tissue on the iris.
Intraoperative peeling of the epithelial membrane from the surface of the lens and excision of the involved iris were performed combined with extracapsular cataract extraction and insertion of a posterior chamber intraocular lens via an open-sky technique through a repeat penetrating keratoplasty opening in the cornea. This resulted in complete resolution of the intraocular epithelialization. Histopathologic examination of the excised tissue confirmed the diagnosis of epithelial ingrowth.
Reposition of traumatically prolapsed iris tissue can result in epithelial ingrowth. Early aggressive surgical intervention can successfully remove all the epithelial tissue from within the anterior segment.
报告一例有晶状体角膜移植患者在创伤性伤口裂开伴虹膜脱出后发生上皮内生(下移生长)的病例,该病例通过早期手术干预成功根除。
对一名70岁单眼、有晶状体患者的介入性病例报告,该患者在创伤性穿透性角膜移植伤口裂开修复后1周内发生上皮内生,虹膜脱出复位36小时。从复位虹膜表面形成一个逐渐扩大的膜,穿过晶状体前囊。氩激光光凝虹膜表面证实了诊断并勾勒出虹膜上皮组织的范围。
术中从晶状体表面剥除上皮膜并切除受累虹膜,同时通过角膜重复穿透性角膜移植切口采用开放式技术进行白内障囊外摘除和后房型人工晶状体植入。这导致眼内上皮化完全消退。切除组织的组织病理学检查证实了上皮内生的诊断。
创伤性脱出的虹膜组织复位可导致上皮内生。早期积极的手术干预可成功从前段清除所有上皮组织。
