Abstract

This paper documents a rare nonprogressive developmental disorder-bilateral circumscribed posterior keratoconus-in a 60-year-old man referred for a cataract surgery. For the first time ultrasound biomicroscopy was used to visualise the local anterior bulging of the posterior corneal surface with concomitant thinning of the stroma. The amount of localized posterior depression, corneal thickness and the refractive power of both the posterior and anterior corneal curvature were measured using slit-scanning topography analysis (Orbscan).

摘要

本文记录了一名因白内障手术前来就诊的60岁男性所患的一种罕见的非进行性发育障碍——双侧局限性后圆锥角膜。首次使用超声生物显微镜观察到角膜后表面局部向前膨隆并伴有基质变薄。使用裂隙扫描地形图分析（Orbscan）测量了局部后凹陷的程度、角膜厚度以及角膜后表面和前表面曲率的屈光力。
