主要用途
Primary clinical use is surgical management of refractory open-angle glaucoma, angle-closure glaucoma unresponsive to laser iridotomy, and select cases of secondary glaucomas (e.g., uveitic, neovascular) when medical and laser therapies fail. It aims to create a controlled aqueous outflow pathway to lower intraocular pressure and prevent optic nerve damage.
正常值范围
Trabeculectomy is a surgical procedure, not a laboratory or diagnostic test with numerical values; therefore, there is no 'normal range' of quantitative measurements. Postoperative success is assessed clinically via intraocular pressure (IOP) targets (typically 6–18 mmHg), absence of progressive optic nerve damage, stable visual fields, and functional bleb morphology — not standardized lab values.
偏低可能原因
N/A — Trabeculectomy is not a measurable test yielding low/high numerical results. However, postoperative IOP <5 mmHg (hypotony) may result from overfiltration, wound leak, choroidal effusion, or excessive antifibrotic use (e.g., mitomycin C).
偏高可能原因
N/A — Trabeculectomy itself has no 'high values', but elevated postoperative IOP (>21 mmHg) may indicate surgical failure due to scarring (fibrosis), bleb encapsulation, inadequate filtration, retained lens material, or pre-existing aggressive glaucoma progression.
