项目介绍
Goldmann压平眼压测量在一般公立医院参考费用约¥55-145，三甲医院参考费用约¥80-180，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
Goldmann applanation tonometry is the clinical gold standard for measuring intraocular pressure (IOP); it is primarily used for glaucoma screening, diagnosis, and longitudinal monitoring; essential preoperatively (e.g., before cataract or refractive surgery), postoperatively (e.g., after glaucoma filtration surgery), and in evaluating suspected ocular hypertension or secondary IOP elevation due to trauma, inflammation, or medication use.
正常值范围
Goldmann applanation tonometry (GAT) normal intraocular pressure (IOP) range is 10–21 mmHg in adults; values below 10 mmHg are considered low, and above 21 mmHg are considered elevated. Diurnal variation of ±3 mmHg is typical, with peak IOP often occurring in the early morning (6–8 AM).
偏低可能原因
Hypotony (IOP < 5 mmHg) may result from: 1) Post-surgical complications (e.g., bleb leak after trabeculectomy or wound leak after cataract surgery), 2) Chronic uveitis with ciliary body atrophy or hyposecretion, 3) Retinal detachment causing reduced aqueous production or increased outflow, 4) Ocular trauma with cyclodialysis cleft, 5) Advanced glaucoma surgery failure or overfiltration.
偏高可能原因
Elevated IOP (>21 mmHg) may be caused by: 1) Primary open-angle glaucoma (POAG), 2) Angle-closure glaucoma (acute or chronic), 3) Steroid-induced ocular hypertension, 4) Pseudoexfoliative or pigmentary glaucoma, 5) Secondary causes such as intraocular inflammation (uveitis), hyphema, or vitreous hemorrhage obstructing aqueous outflow.
