To analyze the results of scanning slit topography in both eyes of patients with unilateral Fuchs heterochromic iridocyclitis (FHI).
A noninterventional, case-controlled study was conducted with 30 patients with unilateral FHI. Corneal topographic parameters, obtained with the Orbscan II (Bausch & Lomb), were compared between the two eyes and analyzed statistically. The same number of age-matched normals was enrolled as a control group.
Thirty patients were enrolled in this study. The mean age was 33.3 years ± 10.6 (SD). The mean Sim K astigmatism was 1.65 ± 1.27 diopter in the FHI eyes and 0.88 ± 0.52 diopter in the normal eyes (p = .001).
Corneal astigmatism is a common finding in patients with FHI and disparity of corneal astigmatism between the two eyes can be considered a sign of the unilateral form of this disease.
分析单侧 Fuchs 异色性虹膜睫状体炎（FHI）患者双眼扫描裂隙体层成像的结果。
本研究为非介入性、对照病例研究，纳入 30 例单侧 FHI 患者。使用 Orbscan II（博士伦）获得角膜地形图参数，对双眼进行比较并进行统计学分析。同时纳入相同数量年龄匹配的正常人为对照组。
本研究共纳入 30 例患者。平均年龄为 33.3±10.6（SD）岁。FHI 眼的平均 Sim K 散光为 1.65±1.27 屈光度，正常眼为 0.88±0.52 屈光度（p=0.001）。
角膜散光在 FHI 患者中很常见，双眼角膜散光的差异可视为这种疾病单侧形式的一个标志。
