Petaloid technique and prognostic significance of macular hole shapes by optical coherence tomography for full thickness macular hole.

Surgical advancements for full-thickness macular hole (FTMH) treatment include vitrectomy, membrane peeling, and the inverted flap technique (IFT). IFT, which involves inverting the internal limiting membrane (ILM) flap over the macular hole (MH) or into the MH, improves success rates and visual recovery. However, issues like mis-aspiration during flap handling have been problematic. We introduce the petaloid technique, to position the ILM flap under air during FTMH surgery to evaluate its outcomes. This retrospective study included 28 eyes, with a mean minimum linear diameter (MLD) 472.04 ± 199.7 μm and basal diameter (BD) of 834.95 ± 593.54 μm. Primary closure of MH was achieved in 96.42% of patients, with 3.57% showing persistent MH during the 6-month follow-up. The VA improved significantly from preoperative levels at each postoperative stage, with notable increases at 3 months (0.86 ± 0.49 logMAR; p = 0.0132) and 6 months (0.77 ± 0.41 logMAR; p = 0.000081). The new closure patterns showed Type A in 28.6%, B in 14.3%, C in 28.6%, and D in 25%. Among different types of closure patterns, although VA improved in all types, significant improvement in VA was noted for type A and type C, with notable improvements at the 6-month follow-up for Type A (0.60 ± 0.23 logMAR; p = 0.02) and at the 1-month follow-up for Type C (0.62 ± 0.28 logMAR; p = 0.02). For macular hole retinal detachment in 5 eyes, the average preoperative VA was 1.86 ± 0.19 logMAR, while the final mean postoperative VA showed a significant improvement to 1.1 ± 0.40 logMAR (p = 0.021, paired t-tests). Retinal reattachment was achieved in all cases (5/5) without recurrent detachment post-silicone oil removal. For the prognostic significance of MH shapes identified by OCT, it can be concluded that the shape of macular holes significantly influences visual acuity outcomes at 6 months post-surgery (p = 0.037). The shape of macular holes, particularly Flask-shaped, significantly impacts visual acuity compared to other shape. The modified petaloid technique for treating FTMH proved safe and effective, with no significant complications noted.

Combined retinal massage and autologous blood covering for persistent macular holes after vitrectomy in high myopia.

To evaluate the efficacy of retinal massage combined with autologous blood covering in the treatment of persistent macular holes following vitrectomy in eyes with high myopia. Retrospective, consecutive case series in a tertiary eye center. A total of 12 highly myopic eyes with persistent macular holes after vitrectomy and internal limiting membrane peeling received combined retinal massage, air/fluid exchange, autologous blood covering, and gas/silicone oil tamponade. Best-corrected visual acuity, axial length, and optical coherence tomographic images before and after the treatment were compared. The mean hole diameter before this intervention was 931.58 ± 244.58 Symbolm (range, 508-1270), and the axial length was 30.39 ± 2.13 mm (range, 27.08-34.64). During the 6-month follow-up period, hole closure was achieved in eight eyes (66.67%). The mean best-corrected visual acuity improved significantly from 1.40 ± 0.50 logarithm of the minimum angle of resolution (logMAR) at baseline to 1.10 ± 0.30 logMAR (P < 0.05). No complications were observed. Combined retinal massage and autologous blood covering, which is easy to manipulate, can promote the closure of persistent macular holes after vitrectomy and improve vision in high myopia with an axial length less than 29 mm.

OPTICAL COHERENCE TOMOGRAPHY FEATURES ASSOCIATED WITH VITREOMACULAR TRACTION RELEASE AND MACULAR HOLE SIZE PROGRESSION FOLLOWING TREATMENT WITH OCRIPLASMIN.

To evaluate OCT features for vitreomacular traction (VMT) release and change in macular hole (MH) size after treatment with ocriplasmin. Patients who had undergone treatment with ocriplasmin for VMT with or without MH ≤400 µm were included. The main outcomes were VMT release and changes in minimum linear diameter MH size at 4 weeks in MHs that persisted. OCT features evaluated were central retinal thickness, vitreomacular adhesion length, posterior vitreous cortex (PVC) insertion angles 500 µm from the insertion points, and minimum linear diameter size. Sixty patients were included: 37 had isolated VMT and 23 VMT with a MH. Four weeks after ocriplasmin injection, the overall VMT release rate was 66.7% (40/60); 64.9% (24/37) in eyes with isolated VMT and 69.6% (16/23) in eyes with MH. VMT release was associated with younger age (P = 0.02). Macular hole closure was achieved in 26.1% (6/23) and was associated with a smaller ratio of the temporal to the nasal PVC angle (P < 0.01). Of the 17 persistent MHs, 76.5% (13/17) increased in minimum linear diameter size from baseline 186 (±78) to 358 (±133) µm (P < 0.001). Progression in minimum linear diameter size showed a negative linear association with the size of the nasal PVC angle (R2 = 0.39, P = 0.002) and a positive linear association with the ratio of the temporal to nasal PVC angle (R2 = 0.39, P = 0.002). In patients with VMT-associated MHs, the risk of MH enlargement following ocriplasmin is negatively correlated with the nasal PVC angle size and is increased if the ratio of the temporal to nasal angle is >1.

Combined Amniotic Membrane Graft and Autologous Retinal Transplant for Repair of Refractory Chronic Myopic Macular Holes

Purpose: To report a technique for reconstruction of large, persistent, chronic, myopic macular holes using a combined human amniotic membrane graft and autologous retinal transplant (AMN-ART). Methods: Three patients with large, myopic macular holes that failed prior surgical attempts and underwent subretinal amniotic membrane graft with overlying autologous retinal transplant and short-term perfluorocarbon tamponade. Pre- and postoperative visual acuity (VA) and images were analyzed at 3, 6, and 9 months. Results: All 3 myopic macular holes remained closed at 9 months with resolution of central scotoma. The first case, a 69-year-old female, presented with a persistent macular hole whose minimum linear diameter was 1085 μm. Her pre-op VA of 20/200 improved by 9 months to 20/100. Secondly, a 72-year-old male with history of recurrent retinal detachment repair with silicone oil and persistent macular hole of 1134 μm presented with pre-op VA of 20/200, which was unchanged at 9 months. Lastly, a 76-year-old female with a persistent macular hole of 935 μm with preop VA of 20/80 improved by 9 months post-op to 20/50. No complications were encountered related to the grafts. Conclusion: Combined AMN-ART may provide a surgical option for repair of refractory, large, chronic myopic macular holes with underlying atrophy.

Dexamethasone Intravitreal Implant to Treat Persistent Full-Thickness Macular Hole.

Purpose: To describe a new technique for the secondary repair of persistent full-thickness macular holes (FTMHs). Methods: This series evaluated 3 cases of a persistent FTMH after pars plana vitrectomy, internal limiting membrane peeling, and 20% sulfur hexafluoride gas tamponade. After at least 4 weeks (mean, 36.3; range, 32-40) of unsuccessful topical treatment with nonsteroidal anti-inflammatory drugs, an intravitreal dexamethasone implant was injected. Results: The intravitreal dexamethasone implant led to anatomic closure and visual improvement in all 3 cases over a 3-month follow-up. Conclusions: An intravitreal dexamethasone implant could be considered in the management of selected cases of persistent FTMH. Further studies and a consistent number of cases are needed to fully understand the role of intravitreal dexamethasone implants in persistent FTMHs.

Hydromassage of macular hole edges for large and persistent full-thickness macular holes.

To introduce the macular hole (MH) hydromassage technique as a potentially beneficial approach for the treatment of large or persistent MH. This retrospective observational case series comprised 16 consecutive patients (17 eyes) diagnosed with MH. Inclusion criteria involved a hole aperture diameter larger than 600 µm or the presence of an unclosed MH larger than 600 µm following the previous vitrectomy. Standard MH repair procedures were administered in all cases, involving the manipulation and aspiration of the hole margin through the application of water flow with a soft-tip flute needle. A comprehensive assessment was conducted for each case before and after surgery, and optical coherence tomography (OCT) images were captured at every follow-up point. The mean preoperative aperture diameter was 747±156 µm (range 611-1180 µm), with a mean base diameter of 1390±435 µm (range 578-2220 µm). Following surgery, all cases achieved complete anatomical closure of MH, with 13 cases (76.5%) exhibiting type 1 closure and 4 cases (23.5%) demonstrating type 2 closure. No significant differences were observed in the preoperative OCT variables between the two closure types. Eyes with type 1 closure showed a significantly improved visual acuity (0.70±0.10, range 0.50-0.80) compared to those with type 2 closure (0.90±0.12, range 0.80-1.00, P=0.014). The MH hydromassage technique demonstrates promising results, achieving acceptable closure rates in cases of large or persistent MH. This technique may serve as an effective adjunctive maneuver during challenging MH surgery.

Autologous internal limiting membrane transplantation achieves anatomic closure and functional improvement in the treatment of large, persistent macular holes

PurposeTo evaluate the clinical outcome of subretinal autologous internal limiting membrane (ILM) transplantation during pars-plana vitrectomy for persistent full-thickness macular hole (FTMH) repair.MethodsRetrospective, consecutive case series of 13 eyes (13 patients) undergoing small-incision vitrectomy with ILM transplantation and air tamponade for large persistent FTMH after prior unsuccessful vitrectomy with posterior hyaloid detachment and ILM peeling.Main outcome measurementsFor all eyes, high-definition spectral domain optical coherence tomography scans (SD-OCT Spectralis, Heidelberg Engineering GmbH, Germany) of the macula were routinely performed before surgery, 1 and 4 weeks after surgery, and at the final follow-up visit. Additionally, age, gender, axial length, macular hole diameter, biomicroscopic fundus evaluation and best‐corrected visual acuity (BCVA) at baseline, 1 and 4 weeks after surgery, and at the final follow-up visit were analyzed.ResultsAnatomic closure was achieved in all 13 cases (100% success rate). Closure pattern was classified in accordance with to Rossi et al. (Graefe’s Arch Clin Exp Ophthalmol 258(12):2629–2638, 2020). Mean baseline BCVA logMAR was 0.93, mean postoperative BCVA logMAR was 0.66 with a mean postoperative follow-up period of 11.4 months. No re-opening occurred during the observation period.ConclusionsPlacing an autologous ILM-transplant in the subretinal space beneath the margin of the FTMH can support anatomic restauration and functional improvement in large, persistent FTMHs.

Long-Term Use of Topical Carbonic Anhydrase Inhibitor Combined with an Initiation of the Two Different Eyedrops for Persistent Macular Hole Following Vitrectomy Combined with Internal Limiting Membrane Peeling: A Case Report

The authors present a long-term course of a woman in her late 50s with persistent full-thickness macular hole (FTMH) after vitrectomy combined with internal limiting membrane peeling subsequently achieved MH closure after receiving topical therapy. Specifically, successful MH closure was observed at eight weeks following an initiation of topical nepafenac, prednisolone acetate, and carbonic anhydrase inhibitor (CAI). Thereafter, the patient was maintained on topical CAI only and achieved 20/32 vision OS with nearly complete restoration of ellipsoidal layers at 18 months postoperative. To conclude, topical therapy may be considered as a non-invasive approach for persistent, cystic, small-apertured MH after vitrectomy procedures. Continuous uses of topical CAI may be of value for sustaining the long-term results.

Relaxing radial retinal incisions for the treatment of persistent macular holes.

Various surgical techniques have been described for managing persistent macular holes after an unsuccessful vitrectomy with internal limiting membrane (ILM) peeling. However, the closure and functional improvement rates after these procedures are limited. Therefore, the aim of this study was to evaluate the usefulness of radial retinal incisions (retinotomies) in eyes with persistent large macula holes despite previous vitrectomy with ILM peeling. In a retrospective case series, closure rate and best-corrected visual acuity (BCVA) were evaluated in eyes with persistent macular holes after an unsuccessful vitrectomy that included posterior vitreous detachment and ILM peeling. 22 eyes of 22 patients (10 men and 12 women) underwent re-vitrectomy with radial retinal incisions. All the patients had undergone an unsuccessful surgery before. Small-incision re-vitrectomy with radial retinal incisions (retinotomies) and air tamponade was performed. For all eyes, high-definition SD-OCT scans (SD-OCT Spectralis, Heidelberg Engineering GmbH, Germany) of the macula were routinely performed before surgery; 1 week and 1 month after surgery; and at final follow-up. Additionally, age, gender, axial length, macular hole diameter, biomicroscopic fundus evaluation and best-corrected visual acuity (BCVA) in logMAR and Snellen at baseline, 1 and 4 months after operation, and at the final follow-up visit were analyzed. The mean baseline macular hole diameter was 668.5 ± 226.8 μm. At the final examination, 16 (72.72%) of the 22 macula holes were closed. Visual acuity increased in 17 eyes, was stable in 3 eyes, and decreased in 2 eyes owing to central retinal atrophy in both. The mean BCVA increased from logMAR 1.04 ± 0.29 at baseline to 0.57 ± 0.31 (Snellen 0.11 ± 0.05 to 0.33 ± 0.18). In all successful cases, macula hole closure was attained after 3 days, and none of the eyes showed macula hole recurrence. The results of this limited case series suggest that radial retinal incisions of the rim in persistent macula holes after initial surgery with ILM peeling increase the success rate of macula hole closure and results in a relevant increase in BCVA. However, as the number of eyes included in this series is limited, the results must be confirmed in a study with a larger sample size.

Closure rates and patterns after light silicone oil tamponade for persistent full-thickness macular holes

PurposeTo report outcomes of re-vitrectomy using light silicone oil (SO) tamponade for persistent macular holes (MHs).MethodsWe reviewed cases of patients with full-thickness MHs that underwent pars plana vitrectomy (PPV) with air/gas and were re-vitrectomized using light SO tamponade after primary non-closure (persistent MHs). Outcome measures included anatomic closure rates and patterns confirmed by optical coherence tomography (OCT) and changes in best-corrected visual acuity (BCVA).ResultsA total of 42 eyes of 41 patients with unsuccessful primary PPV with air/gas were included. After re-vitrectomy with light SO (1000-centistoke), 29 (69%) eyes demonstrated type 1 closure without neurosensory defects in OCT scans, whereas 9 eyes (21%) showed type 2 closure with persisting neurosensory defects. Available data (n = 21) showed a significant mean improvement of BCVA from 0.99 logMAR (SD 0.25, range 0.7–1.3) preoperatively to 0.74 logMAR (SD 0.42, range 0.2–1.5) postoperatively (p = 0.035).ConclusionThe treatment of persistent MHs with PPV and light SO tamponade resulted in high closure rates.

A three-step approach to close refractory persistent macular holes: a releasing-closing-tapping approach

PurposeThe aim of this study was to assess the efficacy and safety of a novel releasing-closing-tapping approach in the treatment of persistent macular holes (PMHs) after initial surgery with internal limiting membrane (ILM) peeling.MethodsWe retrospectively analyzed patients with PMHs after initial surgery with ILM peeling who were treated with a novel releasing-closing-tapping approach. After repeated pars plana vitrectomy (PPV), the surgeon effectively released the adhesion between the edges and retinal pigment epithelium (RPE) by gently scraping the retinal neuroepithelium. Then, the hole was converted into a transverse slit, and the edges were gently tapped flat so that they attached to the RPE, and no space was left under the edges. Finally, air tamponade was carried out. The primary outcome measures included MH closure and the change in best-corrected visual acuity (BCVA) from preoperatively to postoperatively.ResultsThe study included 11 PMH patients with a mean age of 63.82 ± 3.31 years. The mean minimum linear diameter of PMHs was 666.3 ± 208.1 μm, and the mean basal diameter was 1547.2 ± 351.8 μm. MH closure was achieved in 90.9% (10/11) of eyes, with significant improvement of visual acuity from 1.19 ± 0.30 logMAR to 0.65 ± 0.29 logMAR postoperatively.ConclusionThe releasing-closing-tapping approach with repeated PPV is a simple, effective, and safe surgical procedure for refractory PMHs after initial surgery with ILM peeling that can significantly improve the visual outcome and achieve a high surgical success rate.

Outcomes of revision surgery for idiopathic macular hole after failed primary vitrectomy.

Persistent idiopathic macular hole (PIMH), the occurrence of idiopathic macular holes that have failed to close after standard pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling, has become a global health threat to the aging population. Because postoperative anatomic closure or restoration of visual acuity is more difficult to achieve in PIMH, surgical approaches that would yield the best outcomes remain to be elucidated. On paper, extended ILM peeling combined with silicone oil (SiO) tamponade is believed to be a feasible option for excellent macular hole closure. However, no studies on this combined treatment for PIMH is compared with simple air tamponade have been conducted. Thus, in this retrospective case series, we used spectral-domain optical coherence tomography (SD-OCT) and other technologies to investigate real-world evidence for the anatomical and functional outcomes of revisional PPV with either SiO or air tamponade for failed primary idiopathic macular hole surgery. We included the records of 76 patients with PIMH who had SD-OCT examinations and best-corrected visual acuity (BCVA). Regression analysis was performed to find factors affecting PIMH fracture closure. Seventy-six participants were allocated to a SiO group (n = 21, with an extended ILM peeling and SiO tamponade) or an air group (n = 55, with extended ILM peeling and air tamponade). Anatomical success was achieved in 18 (85.7%) and 40 (72.7%) eyes in the SiO and air groups, respectively (p = 0.37). BCVA was significantly improved in both subgroups of closed PIMH (SiO group: p = 0.041; air group: p < 0.001). Minimum linear diameter (MLD) was closely related to the closure rate (OR, 1.0; 95% CI (0.985-0.999); p = 0.03). MLD = 650 μm seemed like a cut-off point for closure rate (MLD ≤ 650 μm vs. MLD > 650 μm; 88.4% vs. 52%, p = 0.002). In conclusion, we demonstrated that extended ILM peeling combined with SiO or air tamponade is effective in PIMH treatment. Moreover, though not statistically significant herein, the anatomic closure rate was better for silicone-operated eyes than for air-operated eyes. MLD is the best predictor of PIMH closure; MLD ≤ 650 μm could achieve a significantly higher closure rate.

Repeat Surgery following Temporal Inverted ILM Flap Technique: Next Step after Primary Failure.

We aimed to report our surgical experience with repeat surgery as the next step after an unsuccessful hole closure with the primary single-layered temporal inverted flap technique (IFT). We identified cases with persistent macular holes by reviewing the records of eyes that underwent IFT between October 2018 and October 2021. These cases were evaluated for hole features, anatomical closure, and visual improvement before and after the first and second surgeries. In addition, the technique applied in repeat surgery was recorded. Optical coherence tomography (OCT) images at follow-up were used to evaluate the flap position. A persistent hole was identified in 11 (6.4%) of 172patients who underwent IFT. An inferotemporal displacement was observed in seven eyes, while no flap could be identified in the OCT images of the other four eyes. In the second surgery, the old flap was reinverted in one eye, and a new flap was created from the superior region in five eyes and the nasal region in the other five eyes and was stabilized under perfluorocarbon liquid. A gas tamponade (C3F8/SF6) was used in all patients at the end of surgery. The minimum hole diameter was > 400 µm in all eyes and 100% closure was achieved after the second surgery. Visual acuity gain of ≥ 3 lines was observed in 9 of the 11 eyes (81.8%). The mean visual acuity increase at the last follow-up was significant (p = 0.008). With single-layer temporal IFT in the primary surgery of macular holes, unsuccessful results may be observed due to the flap displacement in the early period. In our series, IFT was applied again with the use of the old flap or the creation of a new flap in the second surgery of the persistent holes, and successful results were obtained.

A neoteric approach for treatment of persistent macular hole using human amniotic membrane

Treatment of persistent macular holes is a challenge. Various techniques have been devised to reduce the surgical failure rate. We present a case of persistent macular hole treated with human amniotic membrane (hAM). We performed primary 23 Gauge pars plana vitrectomy surgery with internal limiting membrane peeling and perfluoropropane (C3F8) gas. Two weeks postoperatively, spectral domain optical coherence tomography (SDOCT) showed an open macular hole. A secondary surgery using hAM plug as scaffold and C3F8 gas was performed. Three weeks postoperative follow-up SDOCT showed anatomical closure of the macular hole. This suggests that hAM can be an effective substrate for persistent macular holes.

TREATMENT OF PERSISTENT MACULAR HOLES WITH HEAVY SILICONE OIL.

To determine anatomical success and best-corrected visual acuity after secondary surgery with heavy silicone oil tamponade in patients with persistent full-thickness macular holes. In this retrospective study, 63 eyes with persistent full-thickness macular holes after primary pars plana vitrectomy and internal limiting membrane peeling underwent secondary surgery with heavy silicone oil tamponade. Macular spectral domain optical coherence tomography and best-corrected visual acuity measurements were performed during the follow-up. Fifty of 63 eyes (79.4%) achieved anatomical success. In eyes achieving anatomical success, best-corrected visual acuity before primary vitreoretinal surgery was significantly better (0.77 [∼20/125 Snellen] ± 0.24 [1.3-0.3] logarithm of the minimum angle of resolution) compared with eyes not achieving anatomical success (0.88 [∼20/160 Snellen] ± 0.17 [1.1-0.6] logarithm of the minimum angle of resolution, P = 0.044). Minimum linear diameter of full-thickness macular holes was significantly smaller in eyes achieving anatomical success, both before primary (403.4 ± 128.7 [199.0-707.0] µ m vs. 568.1 ± 209.1 [307.0-953.0] µ m, P = 0.009) and secondary surgery (464.1 ± 215.0 [178.0-1,521.0] µ m vs. 663.3 ± 228.5 [451.0-1,301.0] µ m, P = 0.010). Patients remaining phakic during all three surgeries did not benefit from best-corrected visual acuity improvement, although anatomical success was achieved. Heavy silicone oil tamponade in secondary surgery for persistent full-thickness macular holes is a safe and efficient surgical method. Best-corrected visual acuity and minimum linear diameter before surgery may be indicators for anatomical success.

Iatrogenic macular detachment for large macular holes: How to improve this technique

AbstractIatrogenic macular detachment (IMD) with subretinal injection of balance salt solution (BSS) was proposed as an alternative treatment of the large, persistent and chronique macular holes (MH). Subretinal administration of BSS is aimed to detach the edges of the MH decreasing the stiffness and increasing the elasticity of the retina. Hence, the closure of the MH could be improved. Nevertheless, there are still cases that remain refractory to this approach. Preliminary observational studies of the surgery flow with the use of intraoperative optical coherent tomography revealed that in majority of cases after BSS was injected into subretinal space there was strong remaining almost circumferential adhesion between retinal pigment epithelium and photoreceptor outer segments at the edge of MH base. These data differ from the visually percepted MD and showed that in studied cases approximately just 5% to 20% of MH edge circumference were elevated predominantly in temporal area. Subretinal BSS blebs appeared to merge with each other within the macula but outside the MH edges. Additionally, there were no correlation between the size or height of the bleb with the extension of the MD at MH edges. It was noticed that nasally to the MH the adhesion between RPE and OPS was stronger. The causes of this adhesion remain unclear. This hypothesizes that separation of the adhesion could improve the closure rate of the refractory MH using IMD technique. Development of the new surgical approaches together with novel instruments to address the separation of the strong adhesion at the MH edge shall be considered in order to improve the results of iatrogenic macular detachment (IMD) technique in treatment of large, persistent and chronique MH.

What is the best way to treat refractory macular hole?

AbstractBackground: Despite the abundance of surgical approaches proposed for persistent full thickness macular hole (PFTMH) treatment the choice of the optimal technique remains debatable.Purpose: to analyse the anatomical and functional outcome of surgery for persistent macular holes and to determine significant risk factors for failure of primary 25‐g vitrectomy with ILM peeling and gas tamponade for treatment of FTMH.Patients and Methods: Thirty‐eight eyes of thirty‐seven patients with FTMH that underwent primary 25‐gauge PPV, ILM peeling and gas tamponade (GT) were recruited to this retrospective, consecutive, interventional study. Four eyes with persistent holes underwent a re‐operation and outcome‐related factors were discussed.Results: The primary closure rate was 89.5% (34/38). In all failed to close (FTC) cases in this study we used the novel technique recently described by us previously. This manoeuvre included the combination of a subretinal‐fluid application technique with centripetal displacement of the macula and ILM flap technique (inverted pedicle ILM flap technique was used in 3 cases and free ILM flap in 1 case). Four eyes that underwent the repeated surgery obtained final closure. A hole size of &gt;500 μm has a statistically significant effect on the primary macular hole closure (F = 0.048; φ = 0.38; p ˂ 0.05). In the Group 2 with primary unclosed holes, 75% of the eyes (3/4) had an axial length (AL) &gt; 26 mm, while in Group 1 with primary closed holes such eyes were 12.5 times less (2/34) 5.9% (F = 0.004; φ = 0.63; р ˂ 0.01).Conclusion: The combination of a SR‐fluid application technique with centripetal displacement of the macula and ILM flap technique for refractory FTMH provide satisfactory morphologic and functional outcomes. Elongated AL, large diameter of MH and long duration of symptoms are the risk factors for initial closure. Proper second surgery can obtain satisfactory outcomes for persistent holes.

Idiopathic macular hole surgery using inverted temporal internal limiting membrane flap technique

AbstractPurpose: To investigate the anatomic success rate of single‐layered, inverted temporal internal limiting membrane flap (ITF) cover technique for idiopathic macular hole (MH) surgery.Methods: Clinical records of idiopathic MH patients who underwent surgery using ITF technique. Two techniques were used. Group A had circular internal limiting membrane (ILM) peeling and ITF surgery. Group B had hemicircular ILM peeling and ITF surgery. Postop closure of MH was examined by optical coherence tomography.Results: Group A included 18 eyes and Group B included 42 eyes. Immediate postop closure of MH was observed in 83.3% (50 eye); 88.9% (16 eyes) in Group A and 81% (34 eyes) in Group B. Anatomic success rate of large MH was 88.9% (24/27 eyes). Among 10 eyes showing persistent MH after the surgery, 6 eyes had additional intravitreal gas injection treatment and MHs were closed. MHs in other 4 eyes were also closed after the second surgery. In two eyes, ITF flipped back to the original position was observed during the surgery, and reinverting the previous flap induced MH closure.Conclusions: Single‐layered ITF cover technique showed high anatomic success rate in idiopathic MH surgery. However, more attention is needed to prevent the flap flipping.

Comparison of three techniques of harvesting full-thickness retinal tissue for large or persistent macular holes.

To evaluate the success rate of autologous retinal graft (ARG) for the closure of full-thickness macular holes (MHs) and compare the outcomes of three different techniques of harvesting the graft. Clinic files of all patients who had undergone ARG for MH using intraocular scissors, membrane loop, or retinal punch to harvest retinal tissue were retrospectively reviewed. All patients were evaluated for MH closure, retinal reattachment, and visual improvement. Twenty-two eyes of 22 patients were included. ARG was done for 16 eyes (72.7%) with failed, large persistent MH, and six eyes (27.3%) also underwent simultaneous repair of retinal detachment. The basal diameter of MH was 1103.67 ± 310.09 (range 650-1529) μm. Intraocular scissors were used in 10 eyes (45.5%), a membrane loop in five eyes (22.7%), and a retinal punch in seven eyes (31.8%). Silicone oil tamponade was used in seven (31.8%) eyes and gas in 15 (68.1%) eyes. The follow-up ranged from 6 to 18 months. The hole closure rate was 72.7% (16/22). Visual improvement was noted in 18 eyes (81.8%). Retinal reattachment was seen in all eyes. Good graft integration with the surrounding area was seen in 17 eyes (77.3%). Graft retraction was seen in four eyes (18.18%) and graft loss in one eye (4.55%). No significant differences were noted among the three groups. ARG is successful in closing large, failed MH with and without retinal detachment. A membrane loop and retinal punch are equally useful in harvesting the graft, but scissors are preferable in case the retina is detached. With all three techniques, integration of the graft with the surrounding tissue can be achieved.

Intravitreal gas injection for early persistent macular hole after primary pars plana vitrectomy

PurposeTo report the clinical presentations and outcome of early intravitreal injection (IVI) of octafluoropropane (C3F8) for persistent macular holes (MH) after primary pars plana vitrectomy with the internal limiting membrane (ILM) peeling technique.MethodsNineteen eyes of 18 patients with persistent MH after vitrectomy underwent intravitreal injection of C3F8 between 11 and 21 days after the initial surgery (intravitreal gas injection group). Another nine eyes with a persistent MH without additional IVI C3F8 were included (non-intravitreal gas injection group).Best-corrected visual acuity (BCVA), optical coherence tomography (OCT) features including size and configuration of MH, and time duration between the 2 surgeries were compared between the MH closure and open groups. The closure rate of persistent MHs was compared between the intravitreal gas injection group and non-intravitreal gas injection group.ResultsTwelve of 19 eyes (63%) achieved MH closure after 1 to 3 times IVI C3F8. The final BCVA after vitrectomy and IVI gas was significantly better in the MH closure group (P = .005). Nine of 12 patients (75%) in the MH closure group had a visual acuity improvement of more than 2 lines. Original MHs with smaller minimal diameter, higher macular hole index (MHI) and higher tractional hole index (THI); and persistent MHs with smaller minimal diameter, higher THI, and lower diameter hole index (DHI) showed higher MH closure rate. None of the persistent MHs closed in the non-intravitreal gas injection group (0/9 eyes).ConclusionEarly intravitreal injection of C3F8 can be a cost-effective first-line treatment for early persistent MHs after primary surgery, especially in eyes with favorable OCT features.
