青光眼手术中切除小梁与眼压的关系

Correlation of Whether the Trabecula Was Excised or Not in Glaucoma Surgery to Intraocular Pressure

作者随访了青光眼小梁切除术后30例44只眼的眼压、虹膜周边切孔的大小、结膜滤过泡的形状和切除组织病理学检查的关系.切除组织为小梁功能部者21眼,小梁非功能部者4眼,巩膜19眼.术后随访3月以上,眼压正常者37眼,眼压失控者7眼,其中切除组织为小梁功能部4眼,小梁非功能部1眼,巩膜2眼。经X^2检验,眼压的控制与手术切除部位无显著差异(P>0.05).所以手术是否切除了部分功能部小梁组织不是控制眼压的关键。

The intraocular pressure, size of the foramen of peripheral iridcctomy, and the shape of the conjunctival follicle in 30 cases (44 eyes) of glaucoma after trabeculectomy were followed up and the correlation between them and pathological findings of the excised tissue were also studied. The excised tissue belonged to the functional portion of the trabecula in 21 eyes, nonfunctional portion of the trabecula in 4 eyes and sclcra in 19 eyes. Postoperative follow-up over 3 months revealed the intraocular pressure to be normal in 37 eyes, and out of control in 7 eyes, arnong which the excised tissue was; from the functional portion of the trabccula in 4, nonfunctional portion of the trabecula in 1 and sclera in 2. By x2 test, the intraocular pressure had no significant relation to the site of excision (P>0.05). Therefore, whichever part of the functional portion of the trabccular tissue was excised is not essential for the control of the intraocular pressure.
