【摘要】： 目的:觀察玻璃體切割手術治療增殖性糖尿病視網(wǎng)膜病變(proliferative diabetic retinopathy,PDR)的療效。 方法:選取2008年3月～2009年12月由本院眼底病一科同一術者完成玻璃體切割手術治療PDR患者102例(117只眼)的臨床資料進行回顧性分析。對術后視力、手術時機、眼內填充物的應用及與手術相關并發(fā)癥進行探討研究。 結果:(1)PDR IV期組36眼(85.71%),PDR V期組27眼(69.23%),PDR VI期組19眼(52.78%)術后視力提高。(2)在PDR IV期組中,玻璃體積血時間小于2個月組術后視力改善率高于2～3個月組(P=0.032);2～3個月組和大于3個月組沒有顯著的統(tǒng)計學差異(P=1.000)。(3)一次手術后總的視網(wǎng)膜解剖在位數(shù)為112眼(95.73%),PDR IV期組41眼(97.62%),PDR V期組38眼(97.44%),PDR VI期組33眼(91.67%)。(4)術后共19眼(16.24%)出現(xiàn)玻璃體再出血,保留灌注液組、C3F8填充組和硅油填充組玻璃體再出血的差異在統(tǒng)計學上無明顯意義(P=0.882)。術前行PRP組與未行PRP組術后玻璃體再出血的發(fā)生率存在統(tǒng)計學差異(P=0.042)。(5)一次術中摘除晶狀體5眼,3眼于隨訪期內行白內障超聲乳化手術并植入人工晶狀體。(6)術后INV發(fā)生率為5.98%(7眼)。 結論:(1)玻璃體切割手術能有效地改善增殖性糖尿病視網(wǎng)膜病變患者的視力。(2)掌握恰當?shù)氖中g時機對預后十分重要。(3)眼內填充物的應用主要根據(jù)術前或術中是否存在視網(wǎng)膜裂孔。(4)術中對明確的缺血區(qū)域和裂孔進行有效的光凝,術后屈光介質清楚即行熒光造影并補充視網(wǎng)膜激光光凝可以達到良好的效果。(5)術前評估每個患者晶狀體混濁的程度,對術中的晶體進行個性化處理。
[Abstract]:Objective: to observe the effect of vitrectomy on proliferative diabetic retinopathy (proliferative diabetic). Methods: the clinical data of 102 cases (117 eyes) of PDR treated by vitrectomy from March 2008 to December 2009 were retrospectively analyzed. The visual acuity, the timing of operation, the application of intraocular fillers and the complications associated with surgery were studied. Results: (1) postoperative visual acuity was improved in 36 eyes (85.71%) of PDR IV group, 27 eyes (69.23%) in PDR V phase group, 19 eyes (52.78%) in PDR VI stage group, (2) in PDR IV stage group, 19 eyes (52.78%) in PDR IV stage group. The visual acuity improvement rate of vitreous hemorrhage less than 2 months group was higher than that of 2 ~ 3 months group (P0. 032) and more than 3 months group (P < 1. 000). (3). The total number of retina anatomical position after one operation was 112 eyes. (95.73%) of 41 eyes (97.62%) in PDRIV group, 38 eyes (97.44%) in PDRV stage group, 33 eyes (91.67%). (4) in PDRVI stage group, 19 eyes (16.24%) had vitreous rebleeding after operation. There was no significant difference in vitreous rebleeding between C _ 3F _ 8 filling group and silicone oil filling group (P < 0. 882). The incidence of vitreous rebleeding in PRP group was significantly different from that in PRP group (P0. 042). (5). Cataract phacoemulsification and intraocular lens implantation were performed in 3 eyes during the follow-up period. (6) the incidence of postoperative intravitreal hemorrhage was 5.98% (7 eyes). Conclusion: (1) vitrectomy can effectively improve the visual acuity of proliferative diabetic retinopathy. (2) it is very important for the prognosis to grasp the appropriate operative timing. (3) the application of intraocular fillings is mainly based on whether or not the intraocular filling exists before or during the operation. (4) effective photocoagulation of definite ischemic areas and holes during the operation. Fluorescence angiography and retinal laser photocoagulation can achieve good results. (5) evaluate the degree of lens opacity in each patient before operation and individualize the intraoperative lens.
