目的：评估亚洲圆锥角膜 (KC) 患者的角膜地形图。设计：前瞻性观察性病例对照研究。方法：背景：机构。研究人群：总共招募了 116 名 KC 患者（包括双眼）。对照组由 70 名近视激光原位角膜磨镶术 (LASIK) 候选人组成。之前接受过眼科手术和外伤的患者被排除在外。观察程序：使用 Tomey KC 筛选系统（地形建模系统，软件版本 2.4.2J，Tomey Corp，名古屋，日本）和 Orbscan 11 角膜地形图系统（Bausch & Lomb Surgical，Orbtek Inc，盐湖城，犹他州，美国）进行角膜地形图检查。主要观察指标：分析视频角膜地形图变量，将眼分为KC组、KC疑似组和对照组。结果：分析196只眼的角膜地形图。 Tomey (TMS-2N) 和 Orbscan 11 显示的地形图案相似。大多数患有 KC（71.2%）和疑似 KC（70%）的眼睛有不对称的蝴蝶结图案。分析了 TMS-2N 的 13 个指标，发现 KC 组眼睛的指标均值显着高于 KC 可疑组（P
PURPOSE: To evaluate the corneal topographic patterns of Asian patients with keratoconus (KC).DESIGN: Prospective observational case-control study.METHODS: SETTING: Institutional. STUDY POPULATION: A total of 116 patients (both eyes included) with KC were recruited. The control group consisted of 70 laser in,situ keratomileusis (LASIK) candidates with myopia. Patients with previous ocular surgery and trauma were excluded. OBSERVATION PROCEDURE: Corneal topography was performed using the Tomey KC screening system (Topographic Modeling System, software version 2.4.2J, Tomey Corp, Nagoya, Japan) and Orbscan 11 corneal topography system (Bausch & Lomb Surgical, Orbtek Inc, Salt Lake City, Utah, USA). MAIN OUTCOME MEASURES: Videokeratographic variables were analyzed and the eyes were grouped into KC, KC suspect, and control groups.RESULTS: The corneal topographic patterns of 196 eyes were analyzed. The topographic patterns displayed by Tomey (TMS-2N) and Orbscan 11 were similar. The majority of eyes with KC (71.2%) and KC suspect (70%) had asymmetric bowtie patterns. Thirteen indices of TMS-2N were analyzed and the means of the indices were found to be significantly higher in eyes in the KC group than the KC suspect group (P
