在小梁切除术后的最初几天眼压通常是低的,这是由于建立了新的房水引流途径及炎症使房水生成减少的结果。一般在手术后2～4周,当房水生成恢复到正常、手术瘘道和滤过泡的早期疤痕部分地增加了房水排出阻力时,眼压上升到正常范围的中等水平。此时少数病例出现高滤过泡和眼压升高。这些泡在文献上被称为包裹性囊状滤过泡或眼球筋膜囊肿的滤过泡。作者认为用高滤过泡/高眼压期命名较为适宜,这样可以更准确地反映其状况。有人建议恰当的处理是按摩和局部大量应用皮质类固醇,也有人认为必须手术治疗,并报道效果极好。
Intraocular pressure is usually low during the first few days after trabeculectomy as a result of the establishment of a new aqueous humor drainage and reduction of aqueous humor caused by inflammation. Generally 2 to 4 weeks after surgery, intraocular pressure rises to a moderate level in the normal range when aqueous humor returns to normal and early scarring of the surgical fistula and bleb partially increases aqueous humor discharge resistance. At this point a few cases of high filtration bleb and intraocular pressure. These bubbles are known in the literature as filtering blebs of encapsulated cystic bleb or orbital fascia. The authors believe that the use of high-filtration blepharoplasty / ocular hypotension naming more appropriate, so you can more accurately reflect the status. It has been suggested that proper treatment is massaging and topical application of corticosteroids in large quantities, while others consider that surgery is necessary and reports excellent results.
