Abstract
Purpose :
To analyze the clinical efficacy and safety of sutureless 27G+ axial vitrectomy for the treatment of macular epiretinal membrane.
Methods :
Retrospective study. 21 patients with 21 eyes diagnosed as macular anterior membrane and 27G+ axial vitrectomy were included in the study. Recorded surgery time and complications. Follow-up for 3 months after surgery. The difference of visual acuity , intraocular pressure, central macular thickness (CMT) were observed. Statistical between preoperative with postoperative analysis using paired T test.
Results :
The average best corrected logMAR visual acuity of 1 week after operation was not statistically significant compared with the average logMAR before sugery（p＞0.05，t=-1.26）. The average best corrected logMAR visual acuity of 1 day and 3 months after operation were statistically significant compared with the average logMAR before sugery（p＜0.05，t=-5.31，5.0）.The average IOP at 1 day, 1 week, and 3 months after operation were statistically significant differences compared with the preoperation（p＞0.05，t=2.18，0.84，0.69）.The central macular thickness(CMT) of 3 months was statistically significant compared with preoperative (p<0.05, t=6.36). The average vitrectomy time is (20.86±3.15) min. Among them, low intraocular pressure on the 1 day after operation in 1 patient(4.5%); corneal edema on the 1 day after operation in 10 patients(48%); vitreous hemorrhage at 1 week after surgery in 1 patient(5%); filoin keratitis at 1 month postoperatively in 1 patient(5%). In this study, no other complications occurred.
Conclusions :
Sutureless 27G+ axial vitrectomy has good safety and effectiveness for the treatment of macular anterior membrane.
