青光眼

RESULTS: A total of 45 eyes from 45 patients were treated with the Ahmed glaucoma valve implant and its combination surgery. At a mean follow up of 9.7 months (range3～18months), the mean intraocular pressure was reduced from 36.8±12.3mmHg before the implant surgery to 18.0±4.5mmHg at the last follow up after surgery. The success rate was 87%.The best postoperative corrected visual acuity improved 16 eyes(35%).Transient postoperative hypotony and shallow anterior chamber occurred in 20% of cases. The common postoperative complication in later was the formation of encapsulated bleb(13%).

结果：难治性青光眼45例（45眼）实行了Ahmed青光眼阀植入术或联合晶状体摘除、玻璃体切割、人工晶状体植入术等；术后平均观察(3～18)9.7mo；患者术前的平均眼压36.8±12.3mmHg，术后平均眼压18.0±4.5mmHg；手术成功率87%；术后最佳矫正视力提高16眼（35%），视力无变化21眼（47%），视力降低8眼（18%）；术后早期最常见的并发症是一过性浅前房及低眼压，发生率为20%，晚期最常见的并发症是滤过泡包裹，发生率是13%。

METHODS: Ahmed glaucoma valves were implanted in 34 eyes of 34 patients with refractory glaucoma. Density and morphology of corneal endothelial cells were evaluated in the superotemporal, superonasal, infratemporal, infranasal, and central corneal areas to calculate mean value of total cornea before and at 3 and 6 months after surgery. Percentage of hexagonal cells was statistically summarized.

在34例(34眼)疑难青光眼患者眼球颞上象限行Ahmed青光眼阀植入，移植前及移植后3，6个月对角膜中央、颞上、颞下、鼻上及鼻下区内皮摄像后测定分析，得出角膜内皮细胞密度，并取全角膜平均值，同时观察角膜内皮细胞形态变化，统计六角形细胞所占比例。

From Mar. 1987 to Feb. 1990, 19 patients (20 eyes) with chronic angle closure glaucoma underwent argon laser trabeculoplasty 1 month-33 months after laser iridotomy due to uncontrollable lop with maximal tolerable antiglaucoma medication. 15 eyes (75%) were successful within 6 months after ALTP whose IOP remained less than 20 mmHg and no advance in VF defect and optic nerve damage.

从1987年3月到1990年2月3年之间，共有19位慢性隅角闭锁性青光眼病人20只眼睛，在接受雷射虹膜穿孔衍及雷射隅角整形术后，1个月到31个月不等，因眼压以病人本身能忍受之最大剂量抗青光眼药物治疗仍未能得到良好控制，再接受雷射小樑整形术之治疗。

The incidence of primary glaucoma in nonselected population of China is 0.52%. In the population with an age over 40years, the incidence in highly to 1-2%.

在我国非选择性人群中，原发性青光眼的发病率是0.52%，年龄超过40岁的人群中，原发性青光眼的发病率高达1.2%。

1 Ophthalmotonometry is one of the leading methods used during screening examinations and while examining the patient suffered from ophthalmohypertension, glaucoma or with suspicion of glaucoma.

眼压测量是筛选检查和患高眼压、青光眼或怀疑青光眼病人检查中的首要方法之一。

With the development of study in pathogenesy of glaucoma and pharmacology, it have made a great progress in anti-glaucoma drug.

随着人们对青光眼发病机制的研究以及药理学知识和技术的发展，抗青光眼药物也有了很大进展。

However ,when cataracts develop in those patients who already have visual field defects ,it is necessary to differentiate the perimetric attenuation resulting from the cataract from that resulting from glaucomatous field progression.

与人工视野计相比，它能准确地发现青光眼早期的轻微的视野改变[1，2]，而且还能通过分析多次检查结果来评估视野缺损的进展情况[3-9]。然而，有许多青光眼患者同时伴有白内障，这在一定程度上会影响视野检查的结果。

The mfVEPs of patients with glaucoma were statistically lower than those of normal subjects and negatively correlated with interpolated fields. In some cases the RAC of mfVEP between two eyes may be more sensitive to detect the visual dysfunction than the perimetry.

青光眼病人的中心视野转换为插值视野后，发现在青光眼病人的插值视野及mfVEP检查结果之间存在着明显的相关关系，个别病例提示mfVEP双眼间的不对称性改变可能会比中心视野的检测结果更加敏感。

A decrease in phagocytic activity has been proposed in the pathogenesis of glaucoma and glucocorticoid-induced glaucoma.

在青光眼和激素性青光眼的发病机制的研究中已经发现小梁网细胞的吞噬功能有所下降。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
