角巩膜缘对眼内手术切口是非常重要的部位,不掌握角巩膜缘宽度以及它与前房、房角的关系切口是盲目的。在这很小的部位仅零点几毫米之差就会造成手术失败。我国有关角巩膜缘宽度的报告较少,因此我们统计了109眼角巩膜缘表面宽度,并做了3例(4眼)尸检角巩膜缘内部组织解剖测量,现报导于下,以供临床参考。材料和方法109眼基本为40岁以上的老年白内障及各型青光眼病人,男性42眼,女性67眼。对急性闭角性青光眼角巩膜缘不清者未做测量。当剪开球结膜、分离好结膜辦后露出兰灰色角巩膜缘时,用圆规及钢尺进行测量,以结膜反折缘为前缘,以兰灰角巩膜消失处为后缘测其宽度,然后再测11点、1点处两侧。
The scleral limbus is an important part of incision for intraocular surgery. It is blind to grasp the width of the scleral limbus and its relationship with the anterior chamber and angle of the anterior chamber. In this small area only a few millimeters difference will result in surgery failed. In our country, there are few reports on the width of the limbal sclera, so we counted the surface width of the 109 scleral limbus and made 3 cases (4 eyes) of the autopsy of the internal scleral limbus anatomical measurements reported now under for clinical reference. Materials and Methods 109 eyes were aged 40 years old and older with cataract and various types of glaucoma patients, 42 males and 67 females. Acute angle closure glaucoma of the scleral margin were not measured. When cut the bulb conjunctiva, conjunctiva after the separation of the blue gray scleral limbs exposed, with a compass and steel ruler to measure the conjunctival fold edge as the leading edge to blue gray angle sclera disappeared as the trailing edge edge to measure its width, And then test 11 o’clock, 1 o’clock on both sides.
