Abstract
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.
