Results In 950 patients with successful cataractous operations,187 eyes(18.4%)had the vision of super-1.0,395 eyes(39.5%)had the Vision of 1.0-0.5,292 eyes(29.2%)had the vision of 0.5-0.3,106 eyes(10.4%)had the vision of 0.1-0.3,25 eyes(2.5)had the vislon of below-0.1.In 950 patients,242 eyes(24.2%)had diabetic retinopathy,15l eyes(15.1%)had aged-related macular degeneration,27 eyes(2.7%)had ischemic optic neuropathy,7 eyes(0.07%)had choroiditis,15 eyes(1.5%)had retinal vein occlusion,12 eyes(1.2%)had cystoid macular edema,5 eyes(0.2%)had traumatic retinopathy.

结果 950例患者的l 005只眼中，187只眼(18.4%)视力达1.0以上，395只眼(39.5%)视力在1.0-0.5，292只眼(29.2%)视力在0.5-0.3，106只眼(10.4%)视力在0.3-0.1，25只眼(2.5%)视力低于0.1.950例患者的1005只眼中，242只眼(24.2%)息有糖尿病视网膜病变，151只眼(15.1%)息有老年性黄班变性，27只眼(2.7%)息有缺血性视神经病变，7只眼(0.07%)息有陈旧性脉络膜炎，15只眼(1.5%)患有视网膜静脉闭塞，12只眼患有黄斑囊样水肿(1.2%)，5只眼(0.05%)患有外伤性视网膜病变。

Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。

Geometric simplification is thus hard to apply when the visual appearance of an object depends on resolving the ordering and mutual occlusion of even very close-by surfaces, potentially with different shading properties.

几何简化因此是难以用于当一个对象的视觉效果取决于解决的顺序与十分靠近表面的相互遮挡，以及不同的着色属性的简化。
