A case of postcataract epithelial ingrowth that occurred when a chronic fistula was produced after a discussion of a secondary membrane is reported. The ingrowth was examined preoperatively with the specular microscope, and the excised anterior segment was examined with correlative microscopy. The patient recovered 6/18 (20/60) visual acuity after a subsequent penetrating keratoplasty. The characteristics of the epithelial ingrowth consisted of nonkeratinized squamous epithelium with surface microvilli, wide intercellular borders with occasional desmosomes, multiple tonofilaments more prominent in the leading edge of the ingrowth, hemidesmosomes attached to a subepithelial connective tissue layer, and uneven sizes and shapes of epithelial cells. These findings suggested that the source of the ingrowth was from the conjunctival epithelium. We found the leading edge of the ingrowth as well as the type of damage inflicted to the underlying endothelium.
报道了1例在讨论继发性膜后形成慢性瘘管时发生的白内障后上皮内生病例。术前用镜面显微镜检查内生情况，对切除的前段进行相关显微镜检查。患者在随后的穿透性角膜移植术后视力恢复到6/18（20/60）。上皮内生的特征包括：具有表面微绒毛的非角化鳞状上皮、细胞间边界宽且偶尔有桥粒、多个张力丝在生长前沿更突出、半桥粒附着于上皮下结缔组织层以及上皮细胞大小和形状不均。这些发现提示内生来源为结膜上皮。我们发现了内生的前沿以及对下方内皮造成的损伤类型。
