项目介绍
青光眼引流阀植入术（Ahmed、Baerveldt等）在一般公立医院参考费用约¥17500-36000，三甲医院参考费用约¥25000-45000，常用于相关诊断评估与就医安排，费用随医院及地区有所差异。
主要用途
Primary clinical use is surgical management of refractory glaucoma uncontrolled by medications, laser therapy, or trabeculectomy — including neovascular, uveitic, congenital, and secondary glaucomas. Specifically indicated when high failure risk exists for trabeculectomy (e.g., prior failed filtration surgery, active inflammation, young age, Afro-Caribbean ancestry). Ahmed valves are often preferred in high-risk, inflamed eyes due to built-in flow restrictor; Baerveldt implants are used where sustained, lower long-term IOP is desired and inflammation is quiescent.
正常值范围
Not applicable — Ahmed and Baerveldt glaucoma drainage device implantation is a surgical procedure, not a diagnostic laboratory test with numerical values or reference ranges. Intraocular pressure (IOP) postoperatively is typically targeted at 6–18 mmHg, but this reflects therapeutic goal, not a 'normal range' of the surgery itself.
偏低可能原因
N/A — The procedure itself does not yield quantitative 'low values'. However, abnormally low postoperative IOP (<5 mmHg) may result from: 1) Early postoperative hypotony due to excessive aqueous outflow, 2) Tube obstruction by vitreous or fibrin, 3) Overfiltration from inadequate scleral patch graft coverage, 4) Choroidal effusion or detachment, 5) Leakage at tube- or plate-site.
偏高可能原因
N/A — The procedure does not produce 'high values', but elevated postoperative IOP (>21 mmHg) may occur due to: 1) Tube obstruction (e.g., by blood, fibrin, or iris), 2) Plate encapsulation/fibrosis (especially with Baerveldt devices), 3) Failure of initial bleb formation or early scarring, 4) Inadequate intraoperative tube positioning or ligation release timing (for ligated Ahmed valves), 5) Concurrent uncontrolled inflammation or neovascular glaucoma.
