Keratopathy 是角膜病變的統稱，指由不同病因引起的角膜異常或損傷，通常與炎症、變性、代謝異常等因素相關。以下是詳細解釋：

1.定義與分類

• 核心含義：Keratopathy 來源于希臘語“kerato”（角膜）和“pathy”（病變），泛指角膜組織的病理改變，可能累及上皮層、基質層或内皮層。
• 常見類型：
  • 大泡性角膜病變（Bullous Keratopathy）：因角膜内皮細胞功能異常導緻水分積聚，上皮層形成水泡，常見于白内障術後或外傷後。
  • 帶狀角膜病變（Band-shaped Keratopathy）：鈣質在前彈力層沉積，形成灰白色帶狀混濁，多繼發于慢性葡萄膜炎、角膜炎症或代謝性疾病。

2.症狀與表現

• 典型症狀：視力下降、畏光、疼痛、異物感等。例如，大泡性病變伴隨角膜水腫和水泡破裂，帶狀病變可見鈣化斑塊。

3.病因與風險因素

• 内源性：如遺傳性角膜内皮營養不良。
• 外源性：感染、外傷、手術（如白内障摘除）、長期紫外線暴露。

4.治療與管理

• 對症治療：使用人工淚液、降眼壓藥物。
• 手術幹預：嚴重病例需角膜移植（如穿透性角膜移植術）或激光治療（如帶狀病變的EDTA螯合術）。

5.補充說明

• 部分角膜病變可通過早期幹預緩解，但嚴重損傷可能遺留永久性視力損害，需定期眼科檢查。
