玻璃体

Ocular asteroids must be distinguished from the more common typical vitreous floaters, which are usually fibrillar or cellular condensates.

眼部星状物需要区分于典型的玻璃体飞蚊症，玻璃体飞蚊症通常是纤维化的或有细胞凝聚。

Methods1. Twenty-four preretinal fibrovascular membranes were obtained from the patients with PDR during vitrectomy, of them 12 received Avastin intravitreally before surgery and the other 12 did not. Ten preretinal membranes were obtained from patients with proliferative vitreoretinopathy served as controls.

方法1。玻璃体切除术中取出的24例PDR患者的视网膜前新生血管膜，其中术前玻璃体内注射Avastin者12例，未使用Avastin治疗者12例；以10例增生性玻璃体视网膜病变的视网膜前增生膜作为对照。

The intraretinal collagen fibrils penetrating the ILL and mixing with the cortical vitreous fibrils appears to underlie the slow adhesion of the vitreoretinal interface with aging.

随年龄增长来自视网膜内的胶原纤维逐渐穿透ILL与玻璃体皮质纤维缠绕结合，使基底部玻璃体视网膜界面粘连延伸。

Direct cycropexy was performed on each case, in addition, 39 cases were underwent combined surgery, including ECCE, ECCE+IOL, vitrectomy+lensectomy, vitrectomy+lensectomy +IOL, repair of partial iridodialysis.

Methods: Vitrectom was performed on49 patients (49 eyes) diagnosed as vitreous hemorrhage. 25 patients(25 eyes) with ocular injury,9 patients (9 eyes) with diabetic retinopathy, 11 patients(11 eyes) with central retinal vein occlusion, 2 patients (2 eyes)with rhegmatogenous retinal detachment, 1 patient (1 eye) with retinal vein periarteritis, 1 patients with senile macular degeneration.

应用玻璃体切割术治疗玻璃体积血49例（49眼），其中眼外伤25例（25眼），糖尿病性视网膜病变9例（9眼），视网膜中央静脉阻塞11例（11眼），孔源性视网膜脱离2例（2眼），视网膜静脉周围炎1例（1眼），老年性黄斑变性1例（1眼），49例患者均行经睫状体平坦部闭合式巩膜三通道玻璃体切割术。

Re-sults As for intraocular foreign body,14cases of foreign body（10metallic and3nonmetallic）were displayed and1case of tiny ferrous foreign bodywas not displayed.There were also other cases diagnosed in this way,including of vitreous opacification or hemorrhage in13cases,traumatic detachment of retina in9cases postocular puncture injury and ophthal-morrhexis in2cases dislocation of lens into vitreous cavity,1case.

结果 球内异物14例（金属异物11例，非金属异物3例），其中13例球内异物显像，1例微小球内铁质异物不显像；玻璃体混浊或出血13例；外伤性视网膜脱离9例；眼球后段穿孔及破裂伤2例；晶体脱入玻璃体1例。

The visual acuity was light sensation, hand move, counting f ingers/10cm and 002 in 1 eye respectively. 12 eyes can not meet visual inspection, the reflection of strong light was not obvious.13 eyes underwent lensectomy and anterior vitrectomy, 1 eye was implanted intraocular lens, 3 eyes with retin al detachment underwent lensectomy, vitrectomy, photocoagulation, gas tamponade and scleral buckling.

手术前视力1只眼为光感，1只眼为眼前手动，1只眼为数指/10 cm，1只眼为0.02，12只眼不能配合视力检查，对强光刺激反应不明显。13只眼行晶状体切除和前段玻璃体切割，1只眼1期植入人工晶状体， 3只合并视网膜脱离眼行晶状体切除、玻璃体切割、眼内激光光凝、注气、巩膜环扎手术。

Vitrectomy allows us to manage otherwise untreatable ocular pathologies, but the substitution of the vitreous by an artificial intraocular irrigation solution would probably disturb the physiology of the retina and choroids.

随着玻璃体切除术的出现和日益发展，眼内灌注液作为术中使用的玻璃体替代物，直接影响视网膜和脉络膜的正常生理功能。

In the paper the main topics are:(1) to analyze the chemistry composition, the X-ray diffraction, the DTA, and the functions of all raw materials;(2) to define the best direction for producing glass and foam glass, and the best burning technical process;(3) to characterize the unit weight and thermal conductivity of foam glass;(4) to analyze the reason of bubbling up, including the influence factor of temperature, time and so on;(5) to discuss the reasons of leading to shortcomings.There is high content quartz (SiO2) in the two gangues from gold mine and potassium feldspar mine respectively. They can be used to prepare glass, because the quartz (SiO2) is the main raw material.

论文的主要内容包括：1、对矿山尾矿的湿化学分析，粒度、X射线衍射和热稳定性的分析，以及硼砂、碳酸钙及制备泡沫玻璃的玻璃粉、磷酸钠实验原料在实验中的作用进行分析；2、确定尾矿烧结成玻璃体和利用玻璃体烧结泡沫玻璃的最佳配方以及两次烧结的最佳烧成工艺条件；3、泡沫玻璃制品的体积密度和导热系数等物理性能的测定；4、泡沫玻璃的发泡机理分析，包括发泡温度、发泡时间、发泡剂的用量、稳定剂的用量及其它因素对发泡作用的影响；5、讨论造成泡沫玻璃成品各种缺陷的原因及其解决方法。

And there was significant differences between their visual improvement after operation(P0.01).Conclusion In the treatment of retinal detachment with vitreous traction and macular hole,the two methods have similar results in repostion of retinae,but vitrectomy with gas injection was better in visual improvement.

治疗牵引性黄斑裂孔视网膜脱离，2种术式的黄斑孔封闭及视网膜解剖复位率接近，但玻璃体切割注气术视功能恢复方面显著优于黄斑部加压术，玻璃体切割注气术将取代黄斑部加压术。
