  ultrasound biomicroscope
Methods: Thirteen morphometric parameters of the anterior eye segment were measured before and after the application of one drop of pilocarpine in 10 eyes of 5 persons, using a Zeiss-Humphrey Ultrasound Biomicroscope at a frequency of 50 MHz.
      
The first ultrasound biomicroscopy (UBM) was performed between 1 and 3 months following PRK with the 50-80 MHz transducer of a Zeiss-Humphrey Model 840 ultrasound biomicroscope.
      
Methods: Three-dimensional visualisation of the anterior eye section was achieved through extension of the existing ultrasound biomicroscope system (Humphrey Instruments).

Objective To observe the changes of ocular anterior segment and the relation between the intraocular pressure (IOP) and these changes after the topical application of cycloplegia using ultrasound biomicroscope (UBM), especially to observe the changes of ciliary body thickness and ciliary body lens distance. Methods The quantitative measurement of UBM and the measurement of IOP had been done in 48 normal eyes before and after the topical use of 2% homatropine solution. The results were statistically analyzed. Results In the parameter reflecting the change of the anterior chamber angle after using 2% homatropine, the trabecular iris angle decreased, the angle open distance 250 decreased, the iris thickness 1 increased, the anterior chamber became deeper and the iris lens contact distance became shorter, and all these differences were statistically significant ( P <0.05). In the parameter reflecting the changes of ciliary body, the ciliary body thickness and the ciliary process thickness decreased, the scleral ciliary body angle increased, the iris zonule distance decreased and the ciliary body lens distance increased, and all these differences were significant statistically ( P <0.05). The IOP increased from 2.35±0.46 kPa to 2.43±0.47 kPa after the topical use of 2% homatropine, but the differences were not statistically significant ( P >0.05). Conclusions After the topical application of cycloplegia, the anterior chamber becomes deeper, the anterior chamber angle becomes narrower, the ciliary body becomes thinner and moves backward and the ciliary body lens distance increases. By using UBM the structure of ocular anterior segment in its moving state can be observed and these structures can be measured quantitatively. The ultrasound biomicroscopic imaging has its advantages in the morphological study of ocular anterior segment.

目的应用超声生物显微镜观察局部应用睫状肌麻痹剂前、后眼前节形态结构的改变及其与眼压的关系,同时对睫状体厚度、睫状体晶体赤道部距离进行观察。方法以48只正常眼为研究对象,在局部应用2%后马托品前、后分别进行眼前节结构的超声生物显微镜定量测定,并测量眼压。对其结果进行统计学分析。结果用药后在反映房角改变的参数中,小梁虹膜夹角减小,房角开放距离250减小,虹膜厚度1增厚,前房加深,虹膜晶体接触距离缩短,差异均有显著性(P<0.05);在反映睫状体改变的参数中,睫状体和睫状突的厚度减小,巩膜睫状体夹角增大,虹膜悬韧带距离减小,睫状体晶体距离增大,差异有显著性(P<0.05)。应用睫状肌麻痹剂后,眼压由2.35±0.46kPa(1kPa=7.5mmHg)升高至2.43±0.47kPa,但差异无显著性(P>0.05)。结论局部应用睫状肌麻痹剂后,前房加深、房角变窄、睫状体变薄且向后运动、睫状体晶体距离增大。超声生物显微镜能动态观察眼前节结构的改变并行定量测定,在眼前节形态学研究中具有优越性。

Objective To study the mechanism of malignant glaucoma using ultrasound biomicroscope (UBM) combined with general A scan and to observe the conditions of cilio lens block in living eyes at the realtime when malignant glaucoma is occurring. Methods 31 eyes from 27 patients with malignant glaucoma were evaluated and 54 normal eyes and 72 eyes of primary angle closure glaucoma were studied as the controls. Results Of the 31 eyes, close attachments between the ciliary body and the lens were found in 18 eyes (58.1%) and slits between them were found in 13 eyes (41.9%) during the onset of malignant glaucoma. Ciliary body thickness increased significantly ( P <0.05). Fluid in the supraciliary space was found in 11 eyes. Conclusions The mechanism of malignant glaucoma is associated with the abnormal relationship among anterior vitreous, ciliary process and lens periphery. Fluid in the supraciliary space makes the ciliary process closer to the lens periphery. It is one of the factors causing cilio lens block. The ultrasound biomicroscopic image is a new better practicable method to diagnose malignant glaucoma during its onset compared with other methods at present used in the clinical work. It is much more valuable to differentiate the pupillary block glaucoma from malignant glaucoma by using ultrasound biomicroscopy.

目的应用超声生物显微镜结合A超检查睫状环阻滞性青光眼,以了解急性发作时睫状环阻滞的状况。方法对27例(31只眼)抗青光眼术后发生的睫状环阻滞性青光眼进行实时超声生物显微镜检查,与同一眼术前的超声生物显微镜影像进行对比观察;并以54只正常眼和72只原发性闭角型青光眼作为对照研究。结果睫状环阻滞性青光眼发作时,18只眼(58.1%)睫状体和晶体完全相贴,13只眼(41.9%)睫状体和晶体间有一间隙。睫状体厚度明显增厚(P<0.05)。11只眼(35.5%)可见睫状体上腔液。结论在睫状环阻滞性青光眼的发病中,睫状体、晶体和玻璃体三者关系异常是睫状环阻滞性青光眼发病的原因。睫状体上腔液是造成睫状体、晶体阻滞的原因之一。超声生物显微镜检查在睫状环阻滞性青光眼发作时具有较客观的诊断价值

Objective To investigate the mechanism of primary angle closure glaucoma (PACG) especially the role of the changes of ciliary body using ultrasound biomicroscope (UBM) combined with general A scan. Method 99 eyes with PACG, including 50 eyes with acute and 49 eyes with chronic PACG, were evaluated and 58 normal eyes were in the control group. Results Compared with the normal eyes the PACG eyes had their anatomic features. They had a smaller corneal diameter, shorter axial length, shallower anterior chamber, thicker lens, more relative anterior location of lens, swelling of ciliary process and anterior rotation of ciliary body. All these differences were significant statistically (P<0.05). Compared with the chronic PACG eyes the acute PACG eyes had a shallower anterior chamber and a more anteriorly situated lens position. The differences were significant statistically (P<0.01). Compared with the normal eyes the acute PACG eyes had a shorter ciliary body-lens distance and the difference was significant (P<0.05); the chronic PACG eyes also had a shorter ciliary bodylens distance, but the difference was not significant (P>0.05). Conclusions The PACG eyes have their anatomic features. Among these factors the pupillary block caused by the anterior displacement of lens and the narrow angle induced consequently are the common mechanism. The swelling ciliary process, the positional changes of the ciliary body and agerelated thicker lens are possibly the initial causes causing the forward movement of lens, and the pupillary block plays a more important role in the pathogenesis of acute PACG.

目的探讨原发性闭角型青光眼的发病机制,研究睫状体改变在青光眼发病中的作用。方法应用超声生物显微镜(ultrasoundbiomicroscopy,UBM)结合A超检测99只原发性闭角型青光眼及58只正常眼的活体眼前节结构,并对两组测量参数进行对比研究。其中急性闭角型青光眼(急闭)50只眼,慢性闭角型青光眼(慢闭)49只眼。结果原发性闭角型青光眼与正常眼相比,角膜小、前房浅、眼轴短、晶体厚、相对晶体位置偏前、睫状突肿胀、睫状体前置,以上差异均有显著性(P<005)。急闭与慢闭相比,前者前房更浅,相对晶体位置更偏前,差异有显著性(P<001)。急闭与正常眼相比,前者的睫状体与晶体距离较短,差异有显著性(P<005);而慢闭与正常眼相比,前者的睫状体与晶体距离亦较短,但差异无显著性(P>005)。结论原发性闭角型青光眼的发病与其自身的解剖特点有关。其中晶体位置前移导致的瞳孔阻滞及继发的房角变窄是闭角型青光眼发病的共同机制;而睫状突肿胀、睫状体位置的改变及与年龄相关的晶体厚度增大是导致晶体位置前移的可能原发因素。对于急闭而言,瞳孔阻滞是其发病的更重要因素。
