概括

角膜明显影响眼内压力 (IOP) 的测量. 反弹性度计受角膜的影响小于平面化度计,使其在 edematous 眼睛中更可靠地评估 IOP.

科学领域:

眼科医生眼科眼科
兽医医学兽医医学兽医医学
生物医学工程生物医学工程

背景情况:

眼内压力 (IOP) 是诊断和治疗青光眼的关键指标.
精确的IOP测量对于有效的治疗至关重要,但角膜疾病可能会影响读数.
手持式度仪在兽医实践中常用,但它们在角膜病理方面的性能尚未完全理解.

研究的目的:

评估角膜瘤对手持反弹和平面化声度计获得的IOP测量的准确性和精度的影响.
为了比较反弹声计 (TONOVET Plus和TONOVET) 与平声计 (Tono-Pen Vet) 在有或没有角膜的猫眼中的性能.

主要方法:

在活体和外生体研究中,对猫眼进行了诱导或自然发生的角膜.
用TONOVET Plus (TVP),TONOVET (TV01) 反弹计和Tono-Pen Vet (TP) 平计获得眼内压 (IOP) 的读数.
来自 edematous 角膜的读数与同一眼中的透明角膜的读数进行了比较,并与 manometric IOP 测量进行了验证.

主要成果:

反弹度测量 (TVP,TV01) 显示,与透明角膜相比, edematous 区域的 IOP 读数较低 (4.0 ± 5.5 mmHg 差异).
平度计 (TP) 在 edematous 区域显示较高的 IOP 读数 (13.0 ± 5.9 mmHg 差异) 和明显低估了高 IOP 相对于 manometry.
无论是反弹计还是平面计,在出现角膜时,准确度和精度都降低了,而平面计则受到更严重的影响.

结论:

角膜胀会对手持度计的准确性和精度产生负面影响.
反弹度测量对角膜的影响小于平面化度测量,在这种情况下提供更可靠的IOP测量.
如果可能的话,在角膜的患者中,应在透明的角膜区域进行IOP测量,以确保更高的准确性.

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Assessment of blood pressure in brachial artery(two-step method)

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
