Pupillary Block

Objective To study the imaging characteristics of ultrasound biomicroscopy of secondary pupillary block glaucoma .

目的研究继发性瞳孔阻滞性青光眼超声生物显微镜的影像特征。

Posterior chamber pseudophakic pupillary block glaucoma

后房型人工晶体瞳孔阻滞性青光眼

Methods 11 cases with pupillary block glaucoma diagnosed by ultrasound biomicroscopy were studied which had been suspected as malignant glaucoma at the beginning .

方法对11例临床上疑似睫状环阻滞性青光眼，而经超声生物显微镜检查诊断为瞳孔阻滞性青光眼患者的影像特征进行分析。

Neodymium : YAG laser therapy in aphakic pupillary block glaucoma and aphakic malignant ( ciliovitreal block ) glaucoma

Nd：YAG激光治疗无晶体眼瞳孔和睫状玻璃体阻滞性青光眼

To study the relationship between iris ′ s deformation morphology and pupillary block , a method of extracting iris ′ s deformation morphology according to fracture light image was presented on this paper .

为研究虹膜膨隆形态与瞳孔阻滞的关系，提出了一种根据裂隙图像提取虹膜膨隆形态的方法。

Conclusion For complicated cataract after trabeculectomy , uveitis with pupillary block , and serious diabetic cataract , the intraocular surgery through a corneal incision is effective and safe .

结论经角膜切口治疗青光眼小梁切除术后并发白内障、陈旧性葡萄膜炎瞳孔闭锁并发白内障及严重的糖尿病性白内障等，其疗效安全、可靠。

Results : Shallow anterior chambers were caused by leakage of the incision in 9 cases , by pupillary block in 8 cases , by late suprachoroidal bleeding in 1 case .

结果：18例浅前房中，9例为切口漏水，8例为瞳孔阻滞，1例为迟发性脉络膜上腔出血。

Result It was found that the main are were : The obstruction of angle of anterior chamber , the pupillary block , the surgical trauma and the blood-aqueous harrier break down , etc.

结果发现其主要原因为房角阻塞，瞳孔阻滞，手术创伤及血&房水屏障破坏等。

Of the 74 cases were resulted from traumatic retinal detachment combined with dislocation of lens and vitreous , and the last 2 were resulted from pupillary block , in which the IOP could be controlled with surgical treatment .

外伤性晶体脱位、玻璃体嵌顿、视网膜脱离继发青光眼4例，因眼后段疾患行多次手术引起瞳孔闭锁继发青光眼2例，手术治疗后眼压正常。

Results There were no obviously typical characteristics of pupillary block glaucoma shown in the images of ultrasound biomicroscopy in these cases . However , the existence of posterior chamber in each case strongly supported the diagnosis of pupillary block glaucoma .

结果11例患者的超声生物显微镜检查并不表现为典型瞳孔阻滞性青光眼的影像特点，但是后房均存在，支持瞳孔阻滞性青光眼的诊断。

Aphakic pupillary block glaucoma and malignant glaucoma ( ciliovitreal block ) are severe complications of the intracapsular cataract extraction , presenting clinically as elevated intraocular pressure , persistent shallow anterior chamber and severe vitreal hernia .

无晶体眼瞳孔阻滞性青光眼和睫状玻璃体阻滞性青光眼（恶性青光眼）是白内障囊内摘除术的严重并发症，都有眼压升高、前房变浅、玻璃体疝严重等临床表现。

PNP showed that the relative position of pupil margin was located posteriorly , the angle closure was not caused by the pupillary block , but caused by anterior located ciliary body and / or thick and anterior located peripheral iris .

单纯性非瞳孔阻滞型闭青瞳孔缘相对位置靠后，无瞳孔阻滞因素参与，房角关闭与前位的睫状体及附着靠前的周边虹膜肥厚堆积有关；
