Abstract:
Objective:To observe the effect of 25G pars plana vitrectomy (PPV) combined with or without internal limiting membrane (ILM) flap and sterile air or perfluoropropane (C3F8) tamponade in the treatment of idiopathic macular hole (IMH).
Methods:A retrospective case analysis. From December 2015 to December 2016 in Tianjin Eye Hospital, 101 eyes of 98 consecutive IMH patients who underwent 25G PPV combined with or without ILM flap and sterile air or C3F8 tamponade, were included in this study. All patients underwent BCVA and OCT examination. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. The patients were divided into three groups according to preoperative minimum liner diameter of Hole (MLD) and surgical methods: MLD<400 μm for the group A, 41 eyes of 39 patients, MLD more than 400 μm without ILM flap surgery as the group B, 39 eyes of 38 patients, including 16 eyes tamponaded with air and 23 eyes tamponaded with C3F8, MLD more than 400 μm with ILM flap as the group C, a total of 21 patients of 21 eyes, including 7 eyes tamponaded with air and 14 eyes tamponaded with C3F8. The logMAR BCVA of group A, B and C were 0.82±0.39, 1.11±0.42, 1.25±0.50, respectively. The follow-up times were 1 week, 1 month, 3 month, 6 month and 1 year post operation, BCVA and OCT were performed at each follow-up time. The hole closure rate and BCVA improvement were observed.
Results:The postoperative BCVA of group A, B and C was improved obviously,the differences were statistically significant (t=−11.66, −7.52, −4.99; P<0.01). There was no significant difference in improvement of visual acuity between the three groups (A and B, A and C, B and C group: t=0.77, −0.41, 0.28; P=0.44, 0.72, 0.76). 96.94% macular hole closure occurred in 7 days post operation. The postoperative visual acuity improved significantly in 3 mouth after operation,
Conclusions:The macular hole closure occurred mainly in 1 week after operation, postoperative visual acuity increased mostly in the 3rd month post operation. There is no advantage of ILM flap in improve postoperative visual acuity of IMH patients with MLD more than 400 μm.
