玻璃体膜

Ta group: After retinal vein was occluded by the same method used as above, a venipuncture is performed in the locations away from the occluded site about 2/3 to 1 PD distance, a 20G needle tip was used to puncture the retinal vein and underlying retina and the Bruch s membrane.

2手术方法：局部麻醉，标准三切口扁平部玻璃体切除术，术中作玻璃体后界膜的剥离和切除。在四象限视网膜分枝静脉距视盘2一3PD选定的吻合部位，预做局部视网膜光凝，切开静脉管壁和其下的视网膜和Bruch's膜，气/液交换，12%CZF。

Remained posterior hyaloid membrane is a common complication of PPV surgery, and it usually occurs in patients with PDR, RRD without obvious PVR, and early traumatic vitreous hemorrhage.

玻璃体后界膜残留是PPV手术常见并发症，易发生于PDR、无明显PVR的RRD和早期外伤性玻璃体积血患者；玻璃体后界膜残留是PPV术后产生PVR和视网膜脱离的重要原因之一。

In 68 patients (75 eyes), there were 45 cases whose initial diagnosis was Coats disease while the final diagnosis was not, in whom the final diagnosis was old retinal vein occlusion in 21, retinal vasculitis in 9, diabetic retinopathy in 3, old posterior uveitis in 3, congenital retinoschisis in 3, and proliferative vitreoretinopathy, familial exudative vitreoretinopathy, racemose hemangioma, old rhegmatogenous retinal detachment, macular epiretinal membrane, and idiopathic juxtafoveal telangiectasis in 1, respectively.

68例75只眼中，初诊为Coats病，最后确诊为非Coats病45例。其中，最后诊断为视网膜静脉阻塞21例；视网膜血管炎9例；糖尿病视网膜病变3例；陈旧性后葡萄膜炎3例；先天性视网膜劈裂症3例；增生性玻璃体视网膜病变、家族性渗出性玻璃体视网膜病变、视网膜蔓状血管瘤、陈旧性孔源性视网膜脱离、黄斑前膜、特发性黄斑旁毛细血管扩张症各1例。

OBJECTIVE: To investigate the effects of vitrectomy in vitreo-retinal complications associated with intermediate uveitis.

该项研究目的是探讨玻璃体手术治疗中间葡萄膜炎玻璃体视网膜并发症的临床效果。

In particularly Nd:YAG laser can be employed in cataract (anterior capsulectomy, posterior capsulectomy, secondary membranes, dense cataract), closed angle glaucoma, iris and vitreous microsurgery.

特别是钕YAG激光可应用于白内障(前囊膜切除术、后囊膜切除术、继发障膜和浓密的白内障)、闭角青光眼、虹膜和玻璃体显微手术。

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。

Presence of pseudoexfoliation syndrome, nuclear hardness, pupil size, phaco time, effective phaco time, systemic diseases, perioperative complications capsulorhexis rupture, zonular dialysis, posterior capsule rupture .

假性囊膜剥脱综合症，核硬度，瞳孔大小，超声时间，实际超声时间，系统性疾病，术中并发症(囊膜撕裂，悬韧带断裂，后囊破裂伴玻璃体丢失)，IOL植入位置和术后并发症作为膜形成的危险因素分析。

RESULTS: In Phaco group, 79.2％ of the patients visual acuities at the first day after operation were≥0.3. In this group, the nuclear hardnesses of some patients catract were ≤Ⅲ, and others ≥Ⅳ; complications occurred in the former including capsule rupture and vitreous prolapse(4.3%), corneal edema (22.2%); while the latter were 13.7% and 68.6%, respectively.

结果：Phaco组视力≥0.3者79.2%，核硬度≤Ⅲ者后囊膜破裂玻璃体脱出发生率4.3%，角膜水肿发生率22.2%，核硬度≥Ⅳ者后囊膜破裂玻璃体脱出13.7%，角膜水肿68.6%；MSICS组视力≥0.3者78.1%，核硬度≤Ⅲ者后囊膜破裂玻璃体脱出发生率3.8%，角膜水肿发生率19.0%，核硬度≥Ⅳ度者后囊膜破裂玻璃体脱出发生率5.7%，角膜水肿发生率14.3%。

During surgery, 0.1mL of TA was injected into vitreous body to identify and remove vitreous posterior cortex.

术中切除中轴部玻璃体后注入曲安奈德0.1mL于玻璃体腔，以此识别玻璃体后皮质及黄斑前膜，并有效清除。

in terms of idiopathic macular hole, carry out vitrectomy and inner limiting membrance operation earlier is necessary. Compared with 25G group and 20G group of vitrectomy systems, 25G has the advantages that the sight recovering speed is faster, the operation term is shorter, and there is no conspicuous linger effect after operation, etc.

对于特发性黄斑裂孔，早期施行玻璃体切割加内境界膜手术是十分必要的，25G较20G玻璃体手术系统对比具有视力恢复快，手术时间短，术后无明显后遗症等优点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
