摘要
目的 观察正常人及圆锥角膜中胶原Ⅲ、Ⅵ型胶原的表达,探讨Ⅲ、Ⅵ型胶原在圆锥角膜病变中的变化。方法 采用免疫组织化学-SABC法检测角膜组织中Ⅲ、Ⅵ型胶原的表达。结果 Ⅲ型胶原在正常角膜和圆锥角膜的上皮层、实质层及内皮层均有阳性表达,但圆锥角膜比正常角膜的表达弱,而圆锥角膜基质斑块状瘢痕区可见Ⅲ型胶原呈强阳性表达;正常角膜和圆锥角膜组织中在Bowman's层、Descemet's层和基质层均可检测到Ⅵ型胶原表达,但圆锥角膜中Ⅵ型胶原表达减低,特别在圆锥角膜的疤痕区内,Ⅵ型胶原明显降低。结论 Ⅲ、Ⅵ型胶原的异常表达会导致角膜基质纤维间隙的稳定性降低,改变结缔组织中胶原束的组成,最终影响角膜的正常形态。
