To determine whether there is inherent corneal astigmatism in patients with Fuchs' heterochromic iridocyclitis (FHI).
A case-controlled study of 48 patients with unilateral FHI was conducted. These patients had no history of previous surgery or previous diagnosis of glaucoma or cataract. The controls were the fellow eyes of the patients, and the cases were the FHI eyes. All eyes were refracted, and the results were analyzed with descriptive and parametric statistics.
Twenty-one women and 27 men were studied. The mean age was 39.5 years. The mean keratometric value for the astigmatism in the FHI eye was 2.2 diopters (D) (standard deviation +/-1.19) and 0.96 D (+/- 0.64) in the controls (p= 0.000). Refractive astigmatism was 1.44 D (+/-1.45) in FHI eyes and 0.38 D (+/-0.62) in the controls (p= 0.000).
Patients with unilateral FHI have inherent corneal astigmatism in the disease eye.
确定富克斯异色性虹膜睫状体炎（FHI）患者是否存在固有角膜散光。
对48例单侧FHI患者进行病例对照研究。这些患者既往无手术史，也未曾诊断为青光眼或白内障。对照组为患者的对侧眼，病例组为患FHI的眼。对所有眼睛进行验光，并采用描述性和参数统计方法分析结果。
共研究了21名女性和27名男性。平均年龄为39.5岁。FHI患眼角膜散光的平均角膜曲率值为2.2屈光度（D）（标准差±1.19），对照组为0.96 D（±0.64）（p = 0.000）。FHI患眼的屈光性散光为1.44 D（±1.45），对照组为0.38 D（±0.62）（p = 0.000）。
单侧FHI患者患眼存在固有角膜散光。
