目的：观察研究玻璃体腔注射膨胀气体全氟丙烷(C
3F
8)治疗玻璃体黄斑牵引综合征的疗效。
方法：回顾分析12例12眼玻璃体黄斑牵引综合征患者玻璃体腔注射0.3mL C3F8后1mo玻璃体黄斑牵拉情况以及最佳矫正视力、黄斑中心神经上皮厚度的变化情况。
结果：玻璃体黄斑牵拉状态完全解除5眼(42%)。治疗前后患者平均视力分别为0.20 ±0.07，0.25±0.04。黄斑中心神经上皮最大厚度平均减少69μm。
结论：玻璃体腔注射C3F8是一种治疗玻璃体黄斑牵引综合征的有效方法，并且与玻璃体切除手术相比较创伤更小、安全性更高。

AIM: To study the efficacy of a single intravitreal injection of perfluoropropane(C
3F
8)in releasing vitreomacular traction.
METHODS: Twelve eyes of 12 consecutive patients with vitreomacular traction received a single intravitreal injection of 0.3mL 100%(C3F8)were retrospectively analyzed. The best corrected vision acuity and the neural epithelium thickness of central macular were observed.
RESULTS: One month following treatment, vitreomacular traction was released in 5 eyes(42%), mean final visual acuity(VA)improved 0.04 and mean central foveal thickness decreased by 69μm. The vision acuity before and after treatment were 0.20±0.07, 0.25±0.04 respectively.
CONCLUSION: Intravitreal C3F8 injection could offer a minimally invasive alternative to pars plana vitrectomy in patients with vitreomacular traction.
