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 136mm(092~182mm)microscopically at 12 oclock in dults.Meanwhile trabeculetomy was done in 16 eyes.The histology of them shawed that,both Schwalbes 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 05mm anterior and posterior to posterior margin of the limbus and perpendicular to the surface in most eyes.
