The cornea is naturally transparent. Anything that interferes with the cornea's stromal architecture, contributes to blood vessel migration, increases corneal pigmentation, or predisposes to corneal edema, disrupts the corneas transparency and indicates corneal disease. The color, location, and shape and pattern of a corneal lesion can help in determining the underlying cause for the disease. Corneal disease is typically divided into congenital or acquired disorders. Congenital disorders, such as corneal dermoids are rare in cats, whereas acquired corneal disease associated with nonulcerative or ulcerative keratitis is common. Primary ocular disease, such as tear film instability, adenexal disease (medial canthal entropion, lagophthalmus, eyelid agenesis), and herpes keratitis are associated with the majority of acquired corneal disease in cats. Proliferative/eosinophilic keratitis, acute bullous keratopathy, and Florida keratopathy are common feline nonulcerative disorders. Nonprogressive ulcerative disease in cats, such as chronic corneal epithelial defects and corneal sequestration are more common than progressive corneal ulcerations.
角膜天生是透明的。任何干扰角膜基质结构、促使血管迁移、增加角膜色素沉着或易引发角膜水肿的因素，都会破坏角膜的透明度并提示角膜疾病。角膜病变的颜色、位置、形状和形态有助于确定该疾病的潜在病因。角膜疾病通常分为先天性或后天性疾病。先天性疾病，如角膜皮样瘤在猫中很少见，而后天性角膜疾病与非溃疡性或溃疡性角膜炎相关则很常见。原发性眼病，如泪膜不稳定、附属器疾病（内眦睑内翻、兔眼、眼睑发育不全）和疱疹性角膜炎与猫的大多数后天性角膜疾病有关。增殖性/嗜酸性角膜炎、急性大疱性角膜病变和佛罗里达角膜病变是常见的猫非溃疡性疾病。猫的非进行性溃疡性疾病，如慢性角膜上皮缺损和角膜分离比进行性角膜溃疡更常见。
