摘 要:显微镜下对54例62只手术眼进行活体角巩膜缘宽度测量,以结膜返折线为前界,角巩膜缘与不透明巩膜的交界线为后界,测得成人眼12点钟位角巩膜缘宽度为1.36mm(0.92~1.82mm)。同时对16只眼的小梁切除标本行组织学观察发现,9眼见Schwalbe线和小梁结构,3眼见Schwalbe线和前部小梁,1眼见Schwalbe线,1眼见少许睫状肌,2眼未见房角结构。提示:小梁切除术选择以角巩膜缘后界之前、后各0.5mm处垂直于眼球壁的切口较为合理。he width of corneoscleral limbus of 62 living eyes of 54 cases were measured to be 136mm(092~182mm)microscopically at 12 oclock in dults.Meanwhile trabeculetomy was done in 16 eyes.The histology of them shawed that,both Schwalbes line and trabecular meshwork were found in 9 eyes,the line and anterior part of trabecular meshwork is 3 eyes,and the line.ciliary muscles or sclera in others.It is suggested that the incision of trabeculetomy should be plaeed at 05mm anterior and posterior to posterior margin of the limbus and perpendicular to the surface in most eyes.
