上巩膜静脉压力计的临床应用 - 中国实用眼科杂志
本文通过测量正常人及Graves眼病患者的上巩膜静脉压力 (EVP)值,对上巩膜静脉压力计的临床应用作初步的探讨.方法:对74例 (110眼)正常人及35例 (55眼)甲状腺相关性眼病 (Graves眼病)患者分别进行眼科常规检查、眼压测定及EVP检测等.结果:正常眼EVP值与年龄、眼别无关;Graves眼病继发青光眼与EVP升高有关,其眼压 (Pi)与EVP (Pe)的关系符合方程Pi=6.27+0.77Pe.结论:应用上巩膜静脉压力计有助于房水动力学的研究,并且可协助诊断伴有EVP升高的青光眼. 引用本文: 钟毅敏, …

The first practice eye that we had developed in our company was the Laser Eye Model - a practical instrument designed to simulate the interactions of light with ocular tissues present in contemporary surgical and diagnostic ophthalmic procedures.
A practical venomanometer. Measurement of episcleral venous …
Glaucomatous damage develops in certain patients because of elevated episcleral venous pressure (EVP). To measure the EVP in typical clinical settings, a practical and reliable instrument is needed. We have developed such an instrument, the venomanometer, and present tests of …
Episcleral Venomanometer EV-310 - eyetechusa.com
The Episcleral Venomanometer is an instrument that allow clinicians to perform rapid and reliable measurements of the episcleral venous pressure. The instrument is mounted on the slit lamp microscope in the manner similar to the Goldman applanation tonometer .

1983年10月1日 · We measured ICP (using parenchymal pressure monitor), intraocular pressure (using pneumatonometer), episcleral venous pressure (using venomanometer), retinal vein diameter (using OCT images) and...
Glaucomatous damage develops in certain patients because of elevated epi- scleral venous pressure (EVP). To mea- sure the EVP in typical clinical settings, a practical and reliable instrument is needed. We have developed such an instrument, the venomanometer, and present tests of its reproducibility.

Meanwhile, episcleral venous pressure (EVP) is a promising biomarker using a vein in the eye that could be done noninvasively using a venomanometer. Previous research shows that EVP is an excellent biomarker for acute changes in intracranial pressure. Despite having a non-invasive device, current technology for measuring EVP is not portable.
