Closure Of Myopic Macular Hole Research Articles

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

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. 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. 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. 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.

Intraoperative Perfluorocarbon Liquid Tamponade Technique for Treatment of Extensive Retinal Detachment Secondary to a Myopic Macular Hole.

To report an intraoperative perfluorocarbon liquid (PFCL) tamponade technique in treating extensive retinal detachment secondary to a myopic macular hole (MH) through pars plana vitrectomy. The technique was applied in nine eyes with MH-RD extending two quadrants or more areas. The procedures for pars plana vitrectomy included: 1). thorough drainage of subretinal fluid through the MH with fluid-air exchange; 2). PFCL tamponade on the macular area for more than 10 minutes; and 3). repairing the MH after PFCL was removed. All nine eyes gained intraoperative retinal reattachment after PFCL tamponade for 22.22 ± 8.01 minutes and removal of PFCL. Procedures for MH closure included internal limiting membrane peeling in eight eyes, with internal limiting membrane free flap insertion (four eyes), internal limiting membrane inverted flap insertion (two eyes), or lens capsular flap transplantation (three eyes). All eyes received C3F8 tamponade. During 9.11 ± 3.89 months of follow-up, eight of the nine eyes (89%) achieved retinal reattachment and MH closure; one eye achieved anatomical success after reoperations. All eyes had vision improvement at the last follow-up. This new technique in pars plana vitrectomy may promote anatomical and functional recovery in the treatment of extensive retinal detachment secondary to a myopic MH.

ANATOMICAL AND VISUAL OUTCOMES OF INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE VERSUS INTERNAL LIMITING MEMBRANE PEELING IN MYOPIC MACULAR HOLE WITHOUT RETINAL DETACHMENT: A Preliminary Retrospective Study.

To compare the results of vitrectomy with internal limiting membrane (ILM) peeling and inverted ILM flap for treating myopic macular hole without retinal detachment. Twenty-eight eyes of 28 patients undergoing vitrectomy with either ILM peeling (n = 16) or inverted ILM flap technique (n = 12) were included. Outcomes were myopic macular hole closure by optical coherence tomography and visual acuity at 6 months and at the end of follow-up. Closure of myopic macular hole was achieved in 13 eyes (81.2%) of the ILM peeling group and in 11 eyes (91.7%) of the inverted ILM flap group. The median length of follow-up was 18 months in the peeling group and 10.3 in the inverted group. There were not statistically significant differences between restoration of the external limiting membrane, external limiting membrane and ellipsoid zone, and none of both layers between the two groups. The median best-corrected visual acuity (logarithm of minimal angle of resolution) at the end of follow-up was 0.25 (20/35 Snellen) in the peeling group and 0.4 (20/50) in the inverted group (P = 0.027). Both techniques were associated with high closure rates of myopic macular hole but the small sample size and the retrospective design prevents any claims of superiority of one technique over the other.

Prognostic Factor Analysis of Vitrectomy for Retinal Detachment Associated with Myopic Macular Holes

To describe the anatomic and functional outcomes in a cohort of subjects undergoing vitrectomy for retinal detachment (RD) resulting from myopic macular hole (MH) and to analyze the prognostic and surgical factors predicting retinal reattachment and MH closure. Retrospective case series. All patients who underwent vitrectomy for RD resulting from myopic MH between 2000 and 2009 at our center. Case records were reviewed at 6 months after surgery. Retinal reattachment and complete anatomic success, defined as retinal reattachment with MH closure, were assessed. Multivariate logistic regression models, including age, gender, duration of symptoms, spherical equivalent refraction (SE), internal limiting membrane peeling, tamponade choice, and concurrent scleral buckling, were constructed to assess associations with covariates. Retinal reattachment and complete anatomic success (retinal reattachment with MH closure). In total, 114 subjects were analyzed. Most were women (n= 79 [69.3%]), and the mean age was 57.5±13.3 years. The mean SE was-9.88±6.37 diopters. At 6 months, 98 subjects (86.0%) demonstrated retinal reattachment, of whom 93 subjects required only 1 operation. Complete anatomic success was achieved in 61 subjects (53.5%), of whom 55 needed only 1 operation. Subjects with retinal reattachment had better best-corrected visual acuity (BCVA; mean BCVA, 1.22±0.81 logarithm of the minimum angle of resolution [logMAR] units) than those without (mean BCVA, 1.98±1.26 logMAR units; P < 0.001), and subjects with complete anatomic success had better BCVA (mean BCVA, 1.05±0.87 logMAR units) than those without (mean BCVA, 1.62±0.87 logMAR units; P < 0.001). In multivariate analyses, increasing age and the use of perfluoropropane (C3F8) tamponade were predictive of anatomic success (per 1-year increase: odds ratio [OR], 1.049; 95% confidence interval [CI], 1.002-1.099; P= 0.04; and for tamponade: OR, 10.71; 95% CI, 1.08-106.29; P= 0.04). Vitrectomy is effective in the repair of RD resulting from MH in myopic eyes, with retinal reattachment achieved more frequently than MH closure. Retinal reattachment and MH closure are important for improving visual outcomes. Greater age at presentation and use of C3F8 are associated with a greater likelihood of anatomic success.

TREATMENT OF RETINAL DETACHMENT SECONDARY TO MACULAR HOLE IN HIGH MYOPIA

To evaluate the rates of retinal reattachment and the closure of myopic macular hole because of posterior pole retinal detachment after treatment with pars plana vitrectomy and subsequent dissection of the inner limiting membrane. Prospective noncomparative study of 27 eyes from 27 phakic patients diagnosed with posterior pole retinal detachment as a result of myopic macular hole. All underwent pars plana vitrectomy with dissection of the inner limiting membrane and intravitreal silicone oil tamponade performed by the same surgeon. The main variables assessed were visual acuity, retinal reattachment, and macular hole closure determined by optical coherence tomography. Of the 27 eyes, 16 (59.3%) were right eyes and 11 (40.7%) were left eyes. Mean age was 50.5 years. Myopia ranged from -9 diopters (D) to -27 diopters (mean, -18 diopters), and axial length ranged from 28.5 mm to 35.6 mm (mean, 32.05 mm). After a mean postoperative period of 12 months, retinal reattachment was found in 85.1% of the patients and anatomical closure of the macular hole in 51.9%. This technique offers good rates of retinal reattachment and macular hole closure, although seldom increases the final visual acuity. It showed limited effectiveness in eyes with an axial length >30 mm.
