摘要
圆锥角膜是一种以角膜扩张为特征,致角膜中央部向前凸出呈圆锥形及产生高度不规则近视散光和不同视力损害的原发性角膜变性疾病。疾病一般开始于青春期,人群中的发病率为1∶2000,与性别和种族等多种因素相关。其发病原因目前尚不明确,可以从遗传易感性以及生物力学方面去考虑。本文分析了圆锥角膜的临床特点、发病机制、诊断与治疗等方面的研究,指出角膜表面曲率的测量是目前诊断圆锥角膜的最佳方法,在患者有一定视力的情况下,可以通过佩戴眼镜、佩戴硬性角膜接触镜和用角膜交联及板层移植的方法来改善视力,同时阻止圆锥角膜的进展。
Keratoconus characterized with keratectasia is a corneal degeneration primary disease, which leds to central cornea anterior bulging in the form of cone, myopia, astigmatism and even various impairment of vision. This disease always begins in the patients′ puberty, and the morbidity of it is 1/2000 relating to their sex, race or other reasons respectively. The direct reason causing the disease hasn′t been found, and the researchers study the reasons in the angles of hereditary susceptibility and biomechanics. Therefore this paper gives an analysis of the studies of the clinical features, pathogenesis, diagnosis and treatment of keratoconus, and find that corneal surface curvature measurement is the best way to diagnose keratoconus. Moreover paients who have the required vision could improve their vision and stop the progress of keratoconus in the way of wearing glasses or rigid gas-permeable, or accepting corneal crosslinking lamellar keratoplasty.
