瞳孔

RESULTS: Of the 74 patients, 23 (31%) had ocular manifestations accompanied by other symptoms, including 3 (4.1%) with ocular syndrome accompanied with headache as the first symptoms of Moyamoya disease. Digital subtract angiography examination revealed 24 patients (32.4%) had unilateral or double stenosis of internal carotid artery, among which 3 patients had ocular syndrome. All positive eye findings included amaurosis fugax (13%), hemianopia (17%), decline or loss of the visual ability and lesions of visual fields (44%), papillary size dysfunction (13%), pupil direct/indirect light reflex (13%), ptosis (9%), nystagmus (4%), ocular dyscinesia (13%), and fossa orbitalis tenderness (9%).

结果：74例Moyamoya病患者中眼部症状与其它症状同时发生者23例（31%），其中仅以眼部症状伴头痛表现为首发症状就诊者3例（4%）；DSA检查显示单侧或双侧颈内动脉狭窄者24例（32%），其中3例患者双侧颈内动脉完全闭塞，而无任何眼部症状；23例患者所伴眼症表现主要为一过性黑朦13%，偏盲17%，视力下降甚至丧失44%，瞳孔大小异常13%，瞳孔直接/间接对光反射消失13%，上睑下垂9%，眼球震颤4%，眼球运动障碍13%，眼眶压痛9%。

In most applications, ASL operates with a bright pupil image, which provides many advantages over a dark pupil image.

在大多数应用中，ASL公司使用的明亮环境下优质的瞳孔图像，远远超过了黑暗环境中的瞳孔图像。

Objective To investigate an effective method for pupil dilation to facilitate phacoemulcification surgery in cataractous eyes with pupillary membrane secondary to old iridocyclitis, post anti-glaucoma surgery, ocular injury, and so on.

目的探讨一种简单有效的方法使陈旧性虹膜睫状体炎、抗青光眼术後、眼外伤及因虹膜炎症、纤维素膜覆盖致瞳孔无法散大的白内障患者瞳孔扩大，使白内障超声乳化手术得以顺利进行。

Its sclerocorneal muscle and ciliary muscle are flourishing,which cause its ability of double-regulating developed.The iritis sphincter and pupil enlarging muscle can regulate the size of the pupil quickly.There are rods and cones cells in Long-eared owl's retina.The dominant part of the visual cell is the rode cell and the neuromere cell being less that make its eyes high photosensistive.

巩膜角膜肌、睫状肌发达，使其具有很强的双重调节能力；虹膜括约肌、瞳孔放大肌能迅速调节瞳孔大小；视网膜中视细胞由视杆细胞和视锥细胞组成，以视杆细胞占据绝对优势，而神经节细胞较少，从而使其光敏度提高。

Results Forty three cases were died from cerebral hernia before operation 1 week, in which 30 cases with bilateralis mydriasis, and the other 13 cases with half mydriasis. Twenty seven cases died from various complication during 2～3 weeks, in which 11 cases with pulmonary infection, 6 cases with upper gastrointestinal hemorrhage, 5 cases with acute renal failure, 3 cases with multiple organ failure, 1 case with heart failure, 1 case with metabolic disorder of body fluid.

结果术 脑疝形成使中枢衰竭在1周内死亡者43例，其中双侧瞳孔散 30例，单侧瞳孔散大13例；各并发症在2~3周内死亡者27例：肺部感染11例，上消化道出血6例，急性肾功能衰竭5例，脏器功能衰竭3例，心功能衰竭1例，体液代谢紊乱1例。

A new method was given for determining the eye movement in a video-oculography system, where the centroid method was used to get the initial position of eye center, a edge filter was used to obtain all the boundary of the pupil, then a ellipse fatting was used to determine the accurate position of the eye center.

本文提出了一种全自动确定眼动平动的新方法。首先用形心法确定瞳孔的初始位置，再用亚像素边界算子提取瞳孔边界，并用带自动优化功能的椭圆拟合最终确定瞳孔的精确位置。

Methods Forty volunteers with best corrected visual acuity better than 5.0 in the right eye were enrolled in the study. Their ages ranged from 21 years to 32 years; they were all emmetropes or myopes.

对年龄为21~32岁的40例最佳矫正视力≥5.0的近视和正视志愿者分别采用照相机拍摄法、Pupillometer瞳孔测量仪和Rosebaum瞳孔尺三种方法测量瞳孔大小。

High-order RMS showed a lower increase during accommodation when the pupil accommodative miosis was taken into account than when a fixed 4-mm pupil was used.

当调节性瞳孔缩小被考虑时，自然瞳孔状态下高阶像差均方根值在调节中的增加比4毫米固定瞳孔下的相应增加要低。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
