圆锥角膜(Keratoconus)是非炎症性,角膜中轴的膨胀。起病于青少年期、双侧性、女性多见。早期角膜表面有特殊的反光,随后角膜中部出现白色线状混浊,同时向前膨出,呈圆锥形,病程发展缓慢,可在5～6年后停止发展,亦可因台氏膜破裂,发生急性膨胀。角膜中部出现水肿和混浊。我科近年来收治两例圆锥角膜患者,施行部分穿透性角膜移植术,将取下之角膜组织,作电镜及光镜检查,现将结果报道如下:病例1 王××男性11岁因双眼角膜突出、混浊、视力下降3年,于1984年12月20日入院。患者自幼视力较差,81年加重,并发现角膜向前突出,半年前开始
Keratoconus is a non-inflammatory, corneal central axis of expansion. Sick in adolescence, bilateral, more common in women. Early corneal surface has a special reflective, followed by corneal white linear opacities appeared at the same time, bulging forward, was conical, slow course of development may be stopped in 5 to 6 years of development, but also because of Taiwanese rupture occurred Acute swelling. Edema and opacity appear in the middle of the cornea. In recent years, our department treated two patients with keratoconus, the implementation of some penetrating keratoplasty, corneal tissue removed for electron microscopy and light microscopy, the results are reported as follows: Case 1 Wang × × male 11-year-old due to both eyes Corneal prominent, cloudy, decreased visual acuity 3 years, on December 20, 1984 admission. Patients with poor visual acuity since childhood, 81 years increased, and found the cornea protruding forward, six months ago
