摘要

背景:后圆锥角膜是一种罕见的角膜疾病,其特征是角膜后表面弥漫性或局域性突出,形成变薄的间质。它被认为是一种先天性的非进行性疾病。病例报告:报告一例双侧后圆锥角膜局限。诊断性眼部征象包括角膜后表面局部突出、角膜前表面正常、间质变薄和内皮改变。然而,在本例中,角膜前轮廓显示渐进性变陡。结论:后圆锥角膜是一种罕见的角膜异常,临床特征微妙。在诊断和管理过程中,识别这些体征是必不可少的。

Bilateral circumscribed posterior keratoconus.

Background: Posterior keratoconus is a rare corneal disorder characterized by a diffuse or localized protrusion of the posterior corneal surface into a thinning stroma. It is believed to be a congenital, nonprogressive condition.

Case report: A case of bilateral circumscribed posterior keratoconus is presented. Diagnostic ocular signs include localized protrusion of the posterior corneal surface, normal anterior corneal surface, stromal thinning, and endothelial changes. However, anterior corneal contour reveals progressive steepening in this case.

Conclusion: Posterior keratoconus is an unusual corneal anomaly with subtle clinical features. Recognition of these signs is essential in the diagnostic and management processes.
