摘要:

背景:临床治疗糖尿病视网膜病变的过程中,对切除玻璃体后不同填充物的治疗效果及对视网膜、视神经的影响等,目前尚缺乏全面、详细的报道。
目的:观察环状聚二甲基硅氧烷填充后糖尿病视网膜病变患者视网膜、视神经的变化情况。
方法:纳入147例糖尿病视网膜病变患者,其中男77例,女70例,年龄35-70岁,均切除玻璃体,其中74例以环状聚二甲基硅氧烷进行填充(试验组),术后3个月取出状环状聚二甲基硅氧烷;73例以全氟丙烷进行填充(对照组)。随访观察两组术后视网膜、视神经、眼压的变化,以及玻璃体再出血与白内障发生情况。
结果与结论:术后随访7 d,试验组眼压高于对照组(P < 0.05);术后随访6个月,两组眼压比较差异无显著性意义。术后随访6个月,试验组均顺利取出环状聚二甲基硅氧烷,发生视网膜血管变细白鞘、视神经苍白数量高于对照组(P < 0.05),玻璃体再出血与白内障发生率高于对照组(P < 0.05)。表明切除糖尿病视网膜病变患者玻璃体后,予以环状聚二甲基硅氧烷填充可导致视神经萎缩。

Abstract:

BACKGROUND: In the clinical treatment of diabetic retinopathy, the therapeutic effects of different fillers on the retina and optic nerve after the removal of the vitreous are lack of comprehensive and detailed reports.
OBJECTIVE: To observe the changes of retina and optic nerve in patients with diabetic retinopathy after filling cyclic polydimethylsiloxane.
METHODS: Totally 147 patients with diabetic retinopathy undergoing vitreous removal were enrolled, including 77 males and 70 females, aged 35 to 70 years. The vitreous from 74 patients with diabetic retinopathy was filled with cyclic polydimethylsiloxane (test group). The cyclic polydimethylsiloxane was taken out at 3 months post-operation. The vitreous from another 73 patients with diabetic retinopathy was filled with the whole fluorine propane (control group). The changes of retina, optic nerve, intraocular pressure, and the occurrence of vitreous re-hemorrhage and cataract after operation were observed in these two groups.
RESULTS AND CONCLUSION: After 7 days of follow-up, the intraocular pressure of patients in the test group was higher than that in the control group (P < 0.05). After 6 months of follow-up, there was no significant 
difference in the intraocular pressure between these two groups. After 6 months of follow-up, cyclic polydimethylsiloxane was successfully removed in the test group, retinal blood vessels became thinning with the presence of white sheath, and the number of optic nerves was higher than the control group (P < 0.05). The incidence of vitreous re-hemorrhage and cataract in the test was higher than the control group (P < 0.05). These results demonstrate that after the removal of the vitreous, cyclic polydimethylsiloxane filling can lead to optic atrophy in patients with diabetic retinopathy.
