眼压测量与眼压计的介绍
眼压测量与眼压计的介绍眼压是诊断与治疗青光眼的一个必不可少的手段。
眼压测量方法有眼压计法、直接检测法（液体压力计）及指压法。
目前临床上常用的眼压计有Goldmann压平眼压计、Perkins手持眼压计、Tono-Pen眼压计、Proview眼压监测计与非接触式眼压计等。
一、Goldmann压平眼压计1.设计原理Goldmann压平眼压计是国际上用以测量眼压的“金标准”眼压计，它是利用测压头压平角膜来进行间接的眼内压测量。
根据Imbert-Fick原理：Pt（眼内压）＝W（压平角膜的外力）/A（压平面积）而推算的。
Goldmann眼压计的直径为3.06mm，当测压头使角膜压平使7.35㎜2的环形面积所需的力即为眼压测量值。
若需1g的力量加在测压头上，达到7.35㎜2环形面积时，眼压为10mmHg（1克重≈1cm3H2o=1000mm3H2o ，Pt=W/A=W/πr2=1000mm3H2o/[3.14×(3.06/2)2]= 1000mm3H2o/7.35mm2=135.98mmH2o=135.98/13.6(mmHg)=10m mHg），依此类推。
2.Goldmann压平眼压计的结构(1)测压头：为一表面平滑的透明塑料柱，前端可直接接触角膜，作压平角膜用，压平面直径为3.06mm。
后端固定于测压杠杆末端的金属环内。
测压头内有两个基底相反的三棱镜，故能使与角膜接触处的环形物象移位成为两个半圆环形。
另在测压头前端侧面上有径线刻度，供测量高度散光时，作轴向定位用。
(2)测压装置：为一能前后移动的杠杆，其移动度受内部安装的弹簧控制，弹簧的张弛力可被一测压螺旋调整。
在测压螺旋表面有以克重量为单位的重力刻度，表示弹簧的张力(克重量)，范围由0至8g(即相当于0至80mmHg)。
Goldmann 眼压计有“悬吊式”(T900型)与“座式”(R900型)两型。
操作时只需捻转测压螺旋，在裂隙灯显微镜观察下，当角膜压平面达3.06mm直径时，所需压力即眼压值。

9 Electromagnetic declaration (9)INDICATIONS FOR USEThe Icare tonometer TA01i is intended to be used for the measurement of intraocular pressure in the human eye.INTRODUCTIONThe Icare tonometer is used in the diagnosis, follow up and screening of glaucoma. It is based on a new, patented, induction-based rebound method, which allows intraocular pressure (IOP) to be measured accurately, rapidly and without an anesthetic.Since single-use probes are used for measurement, there is no risk of microbiological contamination. No part of the tonometer or probes are made with natural rubber latex. Intraocular pressure changes due to the effects of the pulse, breathing, eye movements and body position. Because measurements are taken using a handheld device in fractions of a second, several measurements are needed to obtain an accurate reading and there fore the software is pre-programmed for six measurements.SAFETY INSTRUCTIONSWARNINGThe tonometer must not come into contact with the patient’s eyes, except for the probes, which may do so for a fraction of a second during measurement. Do not bring the tonometer into contact with the eye or push it into the eye (the tip of the probe should be 4-8mm, or 1/6 – 1/3 inch, from the eye).WARNINGThe tonometer should only be opened by qualified service personnel. It contains no userserviceable parts, apart from the batteries and a probe base. The Icare tonometerrequires no routine servicing or calibration other than changing the batteries at least every 12 months or changing or cleaning the probe base. If servicing is necessary, contact qualified service personnel or your local Icare representative.WARNINGNever spray, pour or spill liquid onto the Icare tonometer, its accessories, connectors, switches or openings in the chassis. Dry any liquid on the surface of the tonometer immediately.WARNINGUse of any accessories and cables other than those specif ied in the manufacturer’s documentation, with the exception of cables sold by the manufacturer as replacement parts for internal components, may result in increased emissions or decreased immunity of the Icare TA01i tonometer.WARNINGUse of any accessory or cable with the Icare TA01i tonometer other than those specified may result in increased emissions or decreased immunity of the Icare TA01i tonometer.CAUTIONRead this manual carefully, since it contains important information on using and servicing the tonometer.Retain this manual for future use.When you have opened the package, check for any external damage or faults, particularly for damage to the case. If you suspect that there is something wrong with the tonometer, contact the manufacturer or distributor.Use the tonometer only for measuring intraocular pressure. Any other use is improper and the manufacturer cannot be held liable for any damage arising from improper use, or for the consequences thereof.Never open the casing of the tonometer, except for the battery compartment or to change the probe base.This manual contains instructions for replacing batteries and changing the probe base.Never use the tonometer in wet or damp conditions.The probe base, battery compartment cover, screws, collar and probes are so small that a child could swallow them. Keep the tonometer out of the reach of children.Do not use the device near inflammable substances, including inflammable anesthetic agents.Prior to each measurement, check that a new disposable probe from an intact package is being used.Be sure that the probe contains the small plastic round tip in front.Certain microbiological agents (e.g. bacteria) can be transmitted from the forehead support.To avoid this, the forehead support should be cleaned regularly with a disinfectant, e.g. an alcohol solution.The tonometer conforms to EMC requirements (IEC 60101-1-2: 2001), but interference may occur in it if used near (<1m) a device (such as a cellular phone) causing high-intensity elect romagnetic emissions. Although the tonometer’s own electromagnetic emissions are well below the levels permitted by the relevant standards, they may cause interference in other, nearby devices, e.g. sensitive sensors.If the device is not to be used for a long time, we recommend that you remove its AA batteries, since they may leak. Removing the batteries will not affect the subsequent functioning of the tonometer.Be sure to dispose of the single-use probes properly (e.g. in a container for disposable needles), because they may contain micro-organisms from the patient.Batteries, packaging materials and probe bases must be disposed of according to local regulations.To obtain firm support for the patient’sforehead, in order to obtain an accuratemeasurement at the right distance, you can adjust the forehead support by turning the forehead supportadjusting wheel.Open the probe tube by removing the cap and insert the probe into probe base as shown in the image. After the probe has been inserted, be careful not to point it down before activating the tonometer in order to prevent the probe from falling out. Activate by pressing the easurement button once and the tonometer will be ready for measurement when 00 appears on the display. After activating the probe is magnetized and will not fall out. CAUTIONFederal law (U.S.) restricts this device to sale by or on the order of a physician.PARTS OF THE TONOMETERTURNING THE TONOMETER ON AND LOADING THE PROBEPlace the wrist strap into the wrist strap attachment. Place the wrist strap around your wrist and secure it. The wrist strap protects the tonometer from dropping onto the floor accidentally. Insert batteries into the tonometer (page 9).Press the measurement button to turn the tonometer ON. The tonometer display will display all of the LCD segments (see the figure beside). Check that all of the segments are functional in the four-digit, sevensegment LCD display.Following a brief pause, the displa y will show “LoAd,” reminding the user to load the single use probe into the tonometer prior to measurement.Load the probe in the following way:MEASUREMENTSince local anesthetic may lower the tonometer reading, we recommend that you refrain from using an anesthetic when performing measurements.Ask the patient to relax and look straight ahead at a specific point. Bring the tonometer near the patient’s eye. The central groove should be in a horizontal position, and the distance from the eye to the front part of the collar shouldbe the length of the collar. In other words, the distance from the tip of the probe to the patient’s cornea (see picture) should be 4-8 mm (1/6-1/3 inch). 1. Forehead support2. Forehead support adjusting wheel3. Display4. Collar5. Selector button6. Measurement button7. Probe base8. Central grooveIf necessary, adjust the distance by turning the forehead support adjusting wheel. Press the measurement button lightly to perform the measurement, taking care not to shake the tonometer. The tip of the probe should make contact with the central cornea. Six measurements are made consecutively. After each successful measurement, you will hear a short beep. Once the six measurements have been performed, the IOP will be shown on the display after the ‘P’.If there is an erroneous measurement, the tonometer will beep twice and display an error message. Press the measurement button to clear the error message. If several erroneous measurements appear, see error messages (page 10).To obtain the most accurate reading, six measurements are required, but the result is also displayed after the first measurement, which can usually be considered valid. The measurement values displayed are average values for all previous measurements (1.-5.). Single measurement values are not shown. Should there be variation between the measurements, ‘P’ will flash on the display after the sixth measurement.Following the performance of the entire measurement, a new measurement series can be begun by pressing the measurement button. The tonometer will then be ready for the next measurement series (00 will show on the display, see page 8).If the user doubts the validity of the measurement (for example, if the probe made contact with the eyelid, or missed the central cornea etc.), we recommend that he/she make a new measurement. In addition, when encountering unusual values (for example over 22mmHg or below 8 mmHg) we recommend the performance of a new measurement to verify the result.*Badouin C, Gastaud P. Influence of topical anesthesia on tonometeric values of intraocular pressure. Ophthalmologica 1994;208:309-313 DISPLAY AFTER MEASUREMENTSBefore After the second measurement After the sixth measurement00 2.13 P 13After the sixth measurement, the letter P appears on the display, followed by the IOP (Intraocular pressure) reading.If the P is blinking, it means that the standard deviation of the measurements is greater than normal.P_ (line down) The standard deviation of the different measurements has a slightly greater value than normally, but the effect on the result is unlikely to be relevant.P-(line in the middle) The standard deviation of the different measurements is clearly greater than normal, but the effect on the result is probably irrelevant. A new measurement is recommended if the IOP is over 19 mmHg.P–(line up) The standard deviation of the different measurements is great and a new measurement is recommended.OTHER FUNCTIONSAccessing old measurement valueFrom the starting position, press the right or left selector buttonuntil ‘Old’ appears on the display. Then press the measurementbutton. You can now ‘scroll’ through the old values by pressingthe selector buttons (right=older, left=more recent, from 0-9).To exit the old values search, press the measurement button.The display will now show the word ‘Old’. Press either selector button to access other functions (00=measurement, End=turning OFF).Turning the tonometer OFFPress either selector butto n until the display shows ‘End‘. Pressthe measurement button for two seconds - the display will show‘byE’ and the tonometer will switch off. The used probe will bepartially ejected.

简述眼压计的工作原理
简述眼压计的工作原理一、引言眼压计是一种用于测量眼压的仪器，通常用于诊断青光眼等眼部疾病。
本文将详细介绍眼压计的工作原理。
二、眼压计的分类根据测量原理和使用场景，眼压计可以分为以下几种：1.接触式眼压计：需要接触到角膜表面进行测量；2.非接触式眼压计：无需接触角膜表面即可进行测量；3.便携式眼压计：体积小、重量轻，适合在户外或临床移动使用；4.台式眼压计：体积大、重量重，适合在医院或诊所等固定场所使用。
三、接触式眼压计的工作原理1.装置接触式眼压计由一个金属柄和一个圆锥形塑料头组成。
塑料头上覆盖着一个小球，该小球与角膜表面相接触。
2.测量原理当小球与角膜表面相接触时，会产生一个力。
这个力会传递到金属柄上，并通过一个弹簧传递到一个指针上。
指针的位置会随着力的大小而改变，因此可以测量出眼压。
3.注意事项接触式眼压计需要直接接触到角膜表面，因此需要消毒，并且需要由专业人员进行操作。
四、非接触式眼压计的工作原理1.装置非接触式眼压计通常由一个光源和一个探测器组成。
在使用时，光源会发射一束光线，探测器会检测这束光线经过角膜后的弯曲程度。
2.测量原理当光线经过角膜时，会受到折射和反射的影响，从而产生弯曲。

眼压计及其选购
眼压计及其选购王英丽摘要：眼压计是定量测量眼压的专用仪器，未来会向便携性、非接触性、高精度性方面不断创新发展。
本文具体描述了目前几款常用眼压计的分类、测量原理并对比了各自优缺点。
同时，结合目前眼压计市场情况，通过分析其性能指标及参数，对其中应用最普遍的喷气式眼压计的选购方法进行了说明。
关键词：眼压计；分类；工作原理；选购方法眼睛是以光作为适宜刺激的视觉生物器官，是一种复合的光学系统。
在几何外形上，眼球可以近似认为是一个充满房液的密闭球体，眼球内部的压力叫做眼内压（IOP），简称眼压，是指包括房水、玻璃体、晶状体和血液在内的眼球内容物对于眼球壁所产生的压力。
眼球为了完成其正常视觉功能，必须维持内压高于大气压的一定水平才能保持形状的稳定。
现代眼科学已证实，人的眼压如同血压一样，是24小时波动的，掌握眼压的变化规律对于眼科疾病的诊断具有重要价值，是用于诊断眼科疾病、观察病情、估测预后、评价疗效等的重要手段和指标之一。
对于眼压过高或过低的病人，实施眼压监测是非常重要的。
图1 眼压计结构图眼压计（如图1）是定量测量眼压的专用仪器，它的工作原理是通过角膜形状变化或直接测量角膜血流脉动压力变化，换算获得眼内压。
到目前为止，已经有数十种眼压计相继问世，在众多的眼压计中，大致可分为压陷式眼压计、压平式眼压计两类，压平式眼压计又可分为接触式压平眼压计和非接触式压平眼压计两大类。
现常用的是非接触式压平眼压计，具有操作简便、测量迅速等优点。
1 眼压计的分类及对比1.1 压陷式眼压计压陷式眼压计起步于20世纪70年代，是测量人体眼压的一种专用仪器，Schiotz 眼压计（SIT）是压陷式眼压计的典型代表。
其工作原理是用一定重量的眼压测杆使角膜压成凹陷，在眼压计重量不变的条件下，压陷越深，其眼压越低，其测量值受眼球壁硬度的影响，智能型的压陷式眼压计通过光机电技术结合，可实现眼压的自动化测量。
压陷眼压计的优点是其结构简单、价格便宜、操作简便， 所以至今仍是临床上主要使用的眼压计之一。
