球结膜和球筋膜疤痕形成为抗青光眼眼外引流手术失败的最常见原因之一。为了研究球筋膜对滤过区疤痕形成的影响,作者对行小梁窦切除的患眼,分手术区切除或不切除球筋膜两组进行对照。切除组18例,未切除组25例。手术前后作全面检查,内服荧光素试验,在显微镜下对滤过泡进行观察。结果表明,保存球筋膜的小梁窦切除术的患者,内服1％染料液之后,经过5～10分钟,出现荧光现象。荧光区呈界线清楚的光圈,宽1～3.5mm,位于巩膜瓣区。尔后,弥散的荧光现象持续25～30分钟。而切除球筋膜的患者,荧光不是局限呈现。而是弥散性。整个荧光区离巩膜瓣边缘远得多。荧光出现的时间,两组相同。
Bulbar conjunctiva and bulb fascia scar formation is one of the most common causes of glaucoma-induced extracorporeal drainage failure. In order to study the effect of the coronoid fascia on the formation of scar in the filtration area, the authors compared the affected area of the trabeculectomy with or without excision of the cornea. 18 cases of resection group, 25 cases of non-resection group. Before and after surgery for a comprehensive examination, oral administration of fluorescein test, under the microscope to observe the filtration bleb. The results showed that the preservation of the fascia of the trabeculectomy patients, after taking 1% dye solution, after 5 to 10 minutes, the fluorescence phenomenon. Fluorescent zone was clear boundary circle, width 1 ~ 3.5mm, located in the scleral flap area. Later, the diffuse fluorescence phenomenon lasted 25 to 30 minutes. The excision of the fascia in patients with fluorescence is not limited to show. But diffuse. The entire fluorescence zone is much farther from the scleral flap edge. Fluorescence occurs at the same time in both groups.
