方法：回顾性分析2015-01/2016-01我院眼科因复杂视网膜脱离接受重硅油充填术的患者30例30眼。观察分析术前及术后的最佳矫正视力(BCVA)、眼压、视网膜复位情况及术后并发症等。

结果：术前与硅油充填术后BCVA的差异，术前与取硅油术后3mo BCVA的差异均有统计学意义(z=-2.198，P=0.028； z=-2.682，P=0.007)。平均术前眼压为16.067±4.025mmHg，硅油充填术后为20.233±8.007mmHg，差异有统计学意义(t=-2.913，P=0.005)； 而硅油取出术后眼压14.933±3.423mmHg，与术前眼压比较差异无统计学意义(t=2.635，P=0.430)。重硅油取出术后视网膜复位率90%，常见并发症为硅油乳化、并发性白内障。

结论：重硅油Densiron 68作为眼内充填物治疗复杂性玻璃体视网膜疾病有效及安全，但由于重硅油乳化率较高、术后易并发白内障，因此临床使用时应严格掌握适应证。

METHODS: A retrospective study of 30 patients(30 eyes)who underwent vitrectomy and HSO tamponade for complex retinal detachment between January 2015 and January 2016. The best corrected visual acuity(BCVA), intraocular pressure(IOP), retinal reattachment and complications after surgery were observed.

RESULTS: There were statistical significances in both the BCVA difference between pre-operation and HSO tamponade, and the BCVA difference between pre-operation and the removal of HSO for 3mo(z=-2.198, P=0.028; z=-2.682, P=0.007). The average intraocular pressure of HSO tamponade group was 20.233±8.007mmHg, and the average intraocular pressure of pre-operation group was 16.067±4.025mmHg, showing significant difference(t=-2.913, P=0.005). Between the pre-operation group and the HSO removed group 14.933±3.423mmHg, there was no significant statistical difference in the analysis of IOP(t=2.635, P=0.430). Anatomical success was achieved in 90% of cases after the removal of HSO. Most common complications were cataract formation and oil emulsification.

CONCLUSION: Densiron-68 is a safe and effective tamponade material for the treatment of complex vitreoretinopathy. However, most common complications are cataract formation and oil emulsification. So clinicians should strictly handle indications and usage during the clinical applications.
