Fluid-air exchange with single syringe for the treatment of persistent macular hole after vitrectomy

Objective To evaluate the efficacy of single syringe fluid-air exchange (SSFAE) for the treatment of persistent idiopathic macular hole(IMH) after vitrectomy. Methods The data of 11 eyes of 10 cases with persistent IMH after vitrectomy from Jan.2015 to Aug.2018 at Subei People’s Hospital Affiliated to Yangzhou University were retrospectively analyzed. All cases received SSFAE in outpatient department. The closure rate of macular hole and the changes of visual acuity after SSFAE were evaluated. Results The rate of macular hole closed after the first SSFAE was 63.63% (7/11), 72.72% (8/11) after the second SSFAE and 81.81% (9/11) after the third SSFAE. Conclusion SSFAE is a simple, safe and efficient method for the treatment of persistent IMH after vitrectomy. Key words: Hole, macular; Vitrectomy; Exchange, fluid-air, single syringe
