Guarded filtration surgery, is commonly used to control the intraocular pressure (IOP) in glaucomatous patients. Filtration surgery lowers the IOP by creating a fistula between the inner compartments of the eye and the subconjunctival space (i.e., filtering bleb). There are several options to improve the function of filtering blebs and to prevent their failure. However, improvement of IOP control after guarded filtration procedures is associated with a higher frequency of bleb-related complications. Early (e.g., bleb leak, excessive filtration, flat anterior chamber, filtration failure) and late (e.g., bleb leak, excessive filtration and hypotony, symptomatic blebs, bleb encapsulation, filtration failure, bleb infection) complications associated with filtering procedures should be managed adequately to prevent further problems. Techniques to improve the function of filtering blebs and to treat postoperative complications have progressed over the past decade.
青光眼患者通常采用小梁切除术来控制眼压。小梁切除术通过在眼内腔与结膜下间隙（即滤过泡）之间形成瘘管来降低眼压。有多种方法可改善滤过泡的功能并防止其失败。然而，小梁切除术后眼压控制的改善与滤过泡相关并发症的发生率较高有关。与滤过手术相关的早期（如滤过泡渗漏、过度滤过、无前房、滤过失败）和晚期（如滤过泡渗漏、过度滤过和低眼压、有症状的滤过泡、滤过泡包裹、滤过失败、滤过泡感染）并发症应得到充分处理，以防止出现进一步问题。在过去十年中，改善滤过泡功能和治疗术后并发症的技术取得了进展。
