Vitrectomy combined with different gas tamponade in treatment of idiopathic macular hole

Objective To evaluate the clinical effect of vitrectomy on idiopathic macular hole with noble gas or not. Methods A total of 70 eyes of 66 patients diagnosed with idiopathic macular hole were divided into 2 groups. Patients were treated with vitrectomy surgery combined with ERM peeling, A/F exchange and gass tamponade. Surgery of A group was tamponaded with noble gas and B group was tamponaded with air. ALL of the operations were treated by the same surgeons. After the treatments,we contrasted the vision,macular hole occlusion,and OCT images of the two patient groups for 1-6 months. Results After operation, vision of the two groups was both improved but T test results between the two groups statistically significant difference at 6 months(t=2.1290, P 0.05). 100% anatomical closure was observed in A group. In B group, 90% anatomical closure was observed on stage 2,85% on stage 3,and 60% on stage 4. Conclusion Observed by this study, vitrectomy combined with noble gass tamponade is an better and ideal method to treat idiopathic macular hole contrasted with air tamponade.
