摘要

背景:圆锥角膜(KC)患者的眼科评估经常显示高度近视和不规则散光屈光矫正。KC患者的不规则角膜散光和中央角膜瘢痕常导致最佳矫正视力的丧失。病例报告:本文讨论了两例临床表现为KC，但单眼Snellen视力异常良好(20/25+或更好)的患者。结论:良好的独立视力与KC的诊断不一定不一致。

Keratoconus with good unaided visual acuities: two case reports.

Background: Ophthalmic evaluation of patients with keratoconus (KC) often reveals highly myopic and irregular astigmatic refractive corrections. Irregular corneal astigmatism and central corneal scarring in patients with KC often result in a loss of best-corrected spectacle acuity. Rigid gaspermeable contact lenses generally optimize visual acuities for patients with KC.

Case reports: Two cases are discussed of patients who manifested clinically diagnosed KC but unusually good unaided Snellen visual acuities (20/25+ or better) in both eyes.

Conclusion: Good unaided visual acuities are not necessarily inconsistent with the diagnosis of KC.
