Purpose. To determine whether the reduction of ganglion cell complex (GCC) thickness is uniform in the parafoveal region after vitrectomy with internal limiting membrane (ILM) peeling for idiopathic macular hole (MH).Methods. Thirty-nine consecutive eyes were studied. Vitrectomy was performed with ILM peeling with brilliant blue G (BBG) staining, and room air was used for an intraocular tamponade. The GCC thickness and retinal sensitivity were measured at the superior, inferior, nasal, and temporal quadrants around the fovea using spectral domain-optical coherence tomography (SD-OCT) and microperimetry (MP-1). The measurements were made at baseline, and at 3 and 6 months postoperatively.Results. In 38 of the 39 eyes, the MH was closed after the initial surgery. At three and six months, the percentage of eyes with significantly thinner GCC areas was higher at the temporal quadrant (40.5% at 3 months and 46.0% at 6 months) than that at the other quadrants (P<0.001, P<0.001, resp.). The retinal sensitivity was also significantly lower in the temporal area than in the other areas (15.7 dB at 3 months,P=0.003; 15.4 dB at 6 months,P=0.006).Conclusion. These findings indicate that the inner retina in the temporal area may be more vulnerable to surgical manipulations than the other areas.

Aim. This study aims to evaluate the morphology of ganglion cell complex (GCC) along with functional outcomes in patients undergoing vitrectomy with ILM peeling and macular abrasion with Tano diamond dusted membrane scrapers (DDMS) for three different stages of the idiopathic macular hole (IMH). Methods. This retrospective study was conducted between April 2019 and December 2019. 33 patients with IMH were included and divided into three groups: stage I, stage II, and stage IV. All patients were subjected to vitrectomy with ILM peeling. Gentle and vigorous macular abrasion was additionally performed for stage II and stage IV patients, respectively. The best-corrected visual acuity (BCVA), GCC thickness (measured by spectral domain-optical coherence tomography (SD-OCT)), and photopic contrast sensitivity (Rodenstock CV 900 Chart Panel) were determined before surgery and at 1- and 3-month follow-ups. Results. Closure of MH was achieved in all the patients. The difference between the preoperative and one- and three-month postoperative values of BCVA was statistically significant in the three groups ( P < 0.01 ). Contrast sensitivity progressively improved in all patients and was statistically significant ( P < 0.01 ). The reduction in GCC thickness during follow-up was 34%–42% of the preoperative measurements. On comparing the mean GCC thickness of the operated and healthy eyes, it was not statistically significant in stage I patients. However, the same when done in stage II and IV was statistically significant with P value < 0.05 and P < 0.01 , respectively. Conclusion. Combining ILM peeling with macular abrasion in advanced stages of MH may facilitate its closure without significantly affecting the functional outcome.

AbstractIt has been reported that the macular region of the retina is displaced after vitrectomy with internal limiting membrane (ILM) peeling in eyes with macular hole (MH), but the displacements of the deeper layers of the eye, e.g. RPE and choroid are unclear following the surgery. We used optical coherence tomography (OCT) and OCT angiography (OCTA) to obtain 3 mm × 3 mm en face images before, and 2, 4, and 8 weeks following the vitrectomy with internal limiting membrane (ILM) peeling from 22 eyes of 22 patients with a MH. The OCT and OCTA images showed displacements of the fovea and choroidal intermediate vessels postoperatively. The degree of displacement of the choroid was significantly less than that of the retina (P < 0.001). The displacements of the choroidal bifurcations were significantly correlated to their preoperative distance from the optic disc (r = −0.467, P < 0.001) and they were significantly correlated with the retinal displacements (r = 0.535, P < 0.001). The retina was displaced inferiorly and centripetally, but these localized displacements were not observed in the choroid. In conclusion, clinicians need to be aware of these displacements when evaluating the subfoveal choroid following the surgery because the displacement is different between the retina and the choroid.

AIM: To explore retinal displacement after surgical treatment for idiopathic macular hole (IMH) with different internal limiting membrane (ILM) peeling patterns. METHODS: Totally 22 eyes from 20 patients with IMH were randomly allocated into two groups, N-T group (11 eyes) and T-N group (11 eyes). For patients in N-T group, ILM was peeled off from nasal to temporal retina. For patients in T-N group, ILM was peeled off from temporal to nasal retina. Preoperative, postoperative 1, 3, and 6mo, autofluorescence fundus images were collected for manual measurement of distances of fixed nasal (N), temporal (T), superior (S), and inferior (I) retinal points (bifurcation or crossing of retinal vessels) around the macula to the optic disc (OD). These were respectively defined as N-OD, T-OD, S-OD, and I-OD. The retinal displacement, macular hole closure rate, and best corrected visual acuity (BCVA) were compared between the two groups after surgery. RESULTS: At postoperative 1, 3, and 6mo, the macula slipped toward the OD, manifested by the decreased T-OD, N-OD, S-OD, and I-OD (P<0.05). No significant difference was found in the T-OD, N-OD, S-OD, and I-OD between N-T group and T-N group. IMH closure rate was 100% both in N-T group and T-N group. There was no significant difference in BCVA between two groups (P<0.05). CONCLUSION: The macula slips toward the OD after successful macular hole surgery. The two different ILM peeling pattern show similar visual outcome and retinal displacement, which means ILM peeling directions are not the influencing factor of postoperative retinal displacement.

Purpose. To evaluate the efficacy of internal limiting membrane (ILM) peeling combined with modified flap inverting under air in the treatment of large idiopathic macular hole (MH). Methods. Eyes with a large idiopathic MH (minimum diameter >550 μm) were included in this study. The surgical procedure included standard 23-gauge pars plana vitrectomy (PPV), ILM peeling, complete fluid-gas exchange, and ILM flap inversion under air. The patients underwent follow-up exam including optical coherence tomography (OCT) and best-corrected visual acuity (BCVA) measurement. Results. Sixteen eyes from 16 patients were included. Mean MH diameter was 681.43 ± 112.12 μm. After a mean follow-up time of 6.25 ± 2.65 months, in all cases, the MH was closed, and the ILM flap could be seen at the inner surface of the fovea. U-shaped and V-shaped MH closure was achieved in 11 and 5 cases, respectively. The BCVA improved significantly from 1.49 ± 0.35 logMAR to 0.89 ± 0.35 logMAR ( p < 0.05 ), and visual acuity of 20/100 or better was achieved in 8 eyes. Conclusion. ILM flap inverting under air was helpful in improving the functional and anatomic outcomes of vitrectomy for large idiopathic MH.
