The effect of vitrectomy combined with C_3F_8 tamponade treatment of macular hole

Objective:To evaluate the clinical effect of vitrectomy combined wit h C3F8 gas tamponade treatment of idiopathic macular hole. Methods:37 eyes of 37 patients with idiopathic macular hole underwent vitrectomy combined gas tampo nade.According to the disease,some measures can be taken,including crystal i ntraoperative resection line,value-added membrane peeling,internal limiting m embrane peeling,gas-liquid exchange,C3F8 gas injection,observing postope rati ve hole closure,visual acuity improvement,etc. Results:Followed up for 12 mo nths,anatomical closure was observed in 33 eyes,and the macular hole was comp letely closed.The success rate was 89.2%.Most of the patients achieved a b ette r final visual acuity. Conclusion:Vitrectomy combined with C3F8 gas tampon ade for idiopathic macular hole can effectively promote the hole closed,improve vis ual acuity.
