上皮组织侵入前房一般见于角膜穿孔伤或眼前部手术后,发病率不很高,一旦发生能严重危害眼球。文献上最早的报导多与角膜穿孔伤有关,后来有报导提及白内障手术后亦可发生。上皮组织侵入前房内生长有3种表现形式,即上皮囊肿,前房内上皮膜及虹膜珍珠瘤。现将收集到的37例上皮囊肿及1例虹膜珍珠瘤作一分析。 Epithelial tissue invading the anterior chamber usually seen in corneal perforation injury or anterior eye surgery, the incidence is not high, in the event of serious harm to the eye. The earliest reports in the literature were related to corneal perforation injuries, and later it was reported that cataract surgery could also occur. Epithelial tissue invasion in the anterior chamber growth has three manifestations, namely, epithelial cysts, anterior chamber epithelial membrane and iris pearl tumor. Now collected 37 cases of epithelial cysts and 1 case of iris pearl tumor for an analysis.
