Comparison of anatomical and functional outcomes of different surgical techniques in myopic macular hole without retinal detachment

AIM: To define the anatomic and functional outcomes of pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling, inverted ILM flap and free ILM patch graft technique for the treatment of myopic macular hole (MH) without retinal detachment. METHODS: Sixty-four eyes of 64 patients who underwent PPV for myopic MH were included. Group 1 consists of patients underwent ILM peeling (n=26), and Groups 2 and 3 consists of patient underwent free ILM patch graft (n=20) and inverted ILM flap procedure (n=18) respectively. Outcomes following surgery were MH closure and best corrected visual acuity (BCVA) in logMAR at 6mo. RESULTS: Closure of MH was obtained in 20 eyes (76.9%) of the Group 1, in 16 eyes (80%) of the Group 2 and in 16 eyes (88.9%) of the Group 3. The mean preoperative and postoperative BCVA was 1.60±0.53 logMAR and 1.27±0.58 logMAR, respectively (P<0.05). There was no significant difference in the postoperative BCVA and anatomical closure rates in the three groups. Although the anatomical closure rate did not differ significantly in the groups, closure of MH tended to be better in the inverted ILM flap technique group at 6mo. CONCLUSION: Different surgical techniques may provide favorable visual and anatomical results for myopic MH surgery. ILM flap techniques offer higher closure rates compared to ILM peeling technique. However, in terms of visual outcomes, the study reveals no difference in three surgical techniques.

Vitrectomy with internal limiting membrane peeling versus its flap insertion for macular hole in high myopia: a Meta-analysis

AIM: To compare the anatomic and functional outcomes between vitrectomy with internal limiting membrane(ILM) peeling and internal ILM flap insertion technique for high myopia macular hole(MH).METHODS: Pub Med, Cochrane Library, EMBASE, and CNKI were systematically searched, and all studies involved MH were included. The closure rate of MH and the postoperative best-corrected visual acuity(BCVA) at 6 mo after the initial surgery were the primary measures. All statistical tests were performed in Review Manager 5.3.RESULTS: Five studies that included 151 eyes of 151 patients were finally included, all of which were retrospectively comparative studies. Between the pars plana vitrectomy(PPV) with ILM peeling surgery and the ILM insertion technique, the latter had significantly better efficacy with respect to the closure rate of MH(OR=21.32, 95%CI=7.25-62.67, P<0.001);However, regarding BCVA at 6 mo after the initial surgery in MH, there was no statistical significance between the groups(OR=-0.04, 95%CI=-0.22-0.14, P=0.66). In addition, regarding the rate of retinal reattachment after the initial surgery, the two different methods were not significantly different(OR=2.22, 95%CI=0.34-14.32, P=0.4).CONCLUSION: Both ILM peeling and ILM insertion technique could significantly improve anatomic outcomes of MH in high myopia with or without retinal detachment(RD), and anatomic outcomes are more effective. However, there is no statistical significance in BCVA at 6 mo after the initial surgery in MH, or in the rate of retinal reattachment after the first surgery, between the two methods.

Abstract：

Objective To evaluate the anatomic and visual outcomes of idiopathic macular holes treated with triamcinolone (TA)-assisted posterior vitreous detachment (PVD) and then internal limiting membrane (ILM) peeling without any dye. Methods Twenty-three patients (23 eyes) with stage Ⅱand Ⅲidiopathic macular holes were enrolled. The best-corrected visual acuity (BCVA), the lens, the duration,stage and size of the macular holes were measured before and after the surgery. The preoperative BCVA was 0.04 to 0.40; the logMAR was 0.398 to 1.398 with the mean of 0.846±0.310. All surgery involved TA-assisted PVD and then ILM peeling without any dye.Combined cataract extraction with vitrectomy was performed on 5 eyes.The follow-up ranged from 6 to 16 months with the mean of 9 months. Results Anatomic macular hole closure was achieved in 22 eyes (95.7%) at the first month after surgery and in 23eyes (100.0%) finally. At the 6th months after surgery, the BCVA was 0.12 to 0.90, logMAR was 0.046 to 0.921 with the mean of 0.410±0.209, compared with preoperative BCVA, the difference was statistically significant (t=6.636, P＜0.0001). BCVA increased in 21 eyes (91.3%) and kept unchanged in 2 eyes (8.7%). There are 1-3 spots self-limited bleeding on the retinal surface when the ILM was peeled in 5 eyes. Postoperative complications included progression of cataract in 9 patients and transient intraocular pressure elevation in 6 patients. Conclusions TA-assisted PVD and then ILM peeling without any dye is an effective and safe surgical technique in stage Ⅱ and Ⅲ idiopathic macular hole.

Abstract：

Objective To evaluate quantification of metamorphopsia in eyes with idiopathic macular hole (IMH) before and after surgical treatment, and investigate its relationship between postoperative visual acuity, the macular hole index (MHI), and the macular hole prognostic factor (HPF). Methods Thirty eyes of 30 patients, who underwent successful vitrectomy and internal limiting membrane (ILM) peeling for IMH and were followed up more than 6 months, were included in the study. The uncorrected visual acuity of the fellow eyes was better than 20/25 and there was no metamorphopsia in that eye. The macular hole closure was confirmed by optical coherence tomography (OCT) scans. Metamorphopsia was evaluated by metamorphopsia-charts (M-chart). OCT, best corrected visual acuity (BCVA) and metamorphopsia were obtained before and after surgery. Vertical (MV) and horizontal (MH) metamorphopsia, macular hole index (MHI, the ratio of the height to the diameter of the base) , and macular hole prognostic factor (HPF,the ratio of the height to the minimum diameter) were measured. The metamorphopsia score was the average value of MV and MH. SPSS 16. 0 statistical analysis software was used for data analysis. Results Preoperative MV and MH were (1.82±0.04)° and (1.81±0.04)°, respectively. Six months after surgery,the MV and MH were (0.17±0.03)° and (0.11±0.03)° respectively. There was significant difference between pre- and post-operative metamorphopsia results (Z=-0.788, P＜0.05). The metamorphopsia score at 6 months after surgery were positively correlated with the value of the postoperative BCVA (LogMAR) (r=0.540, P=0.004) and negatively correlated with the values of preoperative MHI and HPF (r=-0.676,-0.518; P＜0.05). Conclusions Successful vitrectomy and ILM peeling can improve metamorphopsia of IMH. Postoperative metamorphopsia was correlated with the postoperative BCVA and the preoperative macular hole contour.
