PURPOSE
Pellucid marginal degeneration is a noninflammatory thinning disorder typically involving the inferior cornea. We describe a patient with superior corneal thinning similar to classic pellucid marginal degeneration.
METHODS
An 80-year-old man was evaluated for high astigmatism.
RESULTS
The right superior cornea had a prominent band of thinning with ectasia. Both inferior corneas had characteristic zones of thinning without inflammation.
CONCLUSIONS
Superior pellucid marginal corneal degeneration should be considered in the differential diagnosis of superior corneal ectatic disorders.
目的
透明边缘变性是一种非炎症性变薄疾病，通常累及角膜下部。我们描述了一名患有类似于经典透明边缘变性的角膜上部变薄的患者。
方法
对一名80岁男性进行了高度散光评估。
结果
右眼上角膜有一条明显的变薄带并伴有扩张。两只眼角膜下部均有特征性变薄区域且无炎症。
结论
在角膜上部扩张性疾病的鉴别诊断中应考虑上部透明边缘角膜变性。
