Keratopathy 是角膜病变的统称，指由不同病因引起的角膜异常或损伤，通常与炎症、变性、代谢异常等因素相关。以下是详细解释：

1.定义与分类

• 核心含义：Keratopathy 来源于希腊语“kerato”（角膜）和“pathy”（病变），泛指角膜组织的病理改变，可能累及上皮层、基质层或内皮层。
• 常见类型：
  • 大泡性角膜病变（Bullous Keratopathy）：因角膜内皮细胞功能异常导致水分积聚，上皮层形成水泡，常见于白内障术后或外伤后。
  • 带状角膜病变（Band-shaped Keratopathy）：钙质在前弹力层沉积，形成灰白色带状混浊，多继发于慢性葡萄膜炎、角膜炎症或代谢性疾病。

2.症状与表现

• 典型症状：视力下降、畏光、疼痛、异物感等。例如，大泡性病变伴随角膜水肿和水泡破裂，带状病变可见钙化斑块。

3.病因与风险因素

• 内源性：如遗传性角膜内皮营养不良。
• 外源性：感染、外伤、手术（如白内障摘除）、长期紫外线暴露。

4.治疗与管理

• 对症治疗：使用人工泪液、降眼压药物。
• 手术干预：严重病例需角膜移植（如穿透性角膜移植术）或激光治疗（如带状病变的EDTA螯合术）。

5.补充说明

• 部分角膜病变可通过早期干预缓解，但严重损伤可能遗留永久性视力损害，需定期眼科检查。
