The long-term success of filtering surgery is not dependent on surgical technique alone. The development of the filtering bleb in the postoperative period, in particular with regard to wound healing and subconjunctival scarring, is equally important. Morphologic changes of the developing filtering bleb after trabeculectomy can predict early failure even if the intraocular pressure is still normal. A basic understanding of wound healing processes and histologic changes of the developing filtering bleb are mandatory to interpret correctly the morphologic appearance of the developing filtering bleb. In clinical practice, follow-up of the filtering bleb according to a standardized morphologic classification may help to predict outcome and provide clues for the necessity and timing of further treatment.
滤过性手术的长期成功并非仅取决于手术技术。术后滤过泡的形成，尤其是在伤口愈合和结膜下瘢痕形成方面，同样重要。小梁切除术后正在形成的滤过泡的形态学变化即使在眼压仍正常时也可预测早期失败。必须对伤口愈合过程以及正在形成的滤过泡的组织学变化有基本的了解，才能正确解读正在形成的滤过泡的形态学表现。在临床实践中，根据标准化的形态学分类对滤过泡进行随访可能有助于预测结果，并为进一步治疗的必要性和时机提供线索。
