PURPOSE
To report a case of congenital intrascleral epithelial cyst.
METHOD
Case report.
RESULTS
A 3-year-old boy presented with a limbal cyst noticed at birth. The cyst enlarged over the next 3 1/2 years and dissected into the cornea, compromising the visual axis. Excision of the cyst improved the patient's best-corrected visual acuity in the left eye from 20/80 to 20/30. Upon histopathology, the cyst wall was lined by conjunctival epithelium.
CONCLUSION
This congenital intrascleral epithelial cyst later enlarged and dissected into the cornea. We believe that the cyst developed secondary to congenital sequestration of conjunctival epithelium.
目的
报告一例先天性巩膜内上皮囊肿病例。
方法
病例报告。
结果
一名3岁男孩出生时即被发现有角膜缘囊肿。在接下来的3年半时间里囊肿逐渐增大并侵入角膜，累及视轴。囊肿切除术后，患者左眼的最佳矫正视力从20/80提高到了20/30。组织病理学检查显示，囊肿壁内衬结膜上皮。
结论
这个先天性巩膜内上皮囊肿后来增大并侵入角膜。我们认为该囊肿是由于结膜上皮先天性分离所致。
