Closure of Full-thickness Macular Hole after Pars Plana Vitrectomy (23G) with Cataract Phacoemulsification, Artificial Intraocular Lens Implantation, and Silicone Oil Administration Due to Rhegmatogenous Retinal Detachment in the Right Eye in a 67-year-old Patient – a Case Report

Macular holes pose a significant threat to central vision, necessitating precise diagnosis and intervention with an occurrence of 1 per 1000 patients over the age of 55. This manuscript presents a case study of a 66-year-old man with a retinal detachment in the right eye and full-wall macular hole. The patient underwent a multi-step surgical intervention involving pars plana vitrectomy, internal limiting membrane peeling with silicone oil tamponade, retinal endophotocoagulation, and administration and removal of the perfluorocarbon liquid DK-line in the first step. The second stage of treatment comprised silicone oil removal via posterior access vitrectomy, injection of 25% SF6 into the right eye, and treatment of intraoperatively found macular hole with an inverted flap method. The case underscores the association between macular hole and rhegmatogenous retinal detachment, with potential iatrogenic causes during vitrectomy. The inverted internal limiting membrane flap technique emerged as a superior strategy for managing full-thickness macular holes, demonstrating high closure rates and improved visual acuity postoperatively. This case study contributes to the evolving understanding of macular hole pathogenesis and reinforces the significance of tailored surgical approaches for optimal patient outcomes.

Nonsurgical closure of full thickness macular hole under topical therapy in two eyes with pathologic myopia.

Non-surgical closure of a full-thickness macular hole (FTMH) with eye drops has recently been reported, but there are few similar reports in cases with pathologic myopia. (Case 1) The right eye of a 75-year-old female with an axial length of 28.83 mm had undergone anti-vascular endothelial growth factor (VEGF) treatment for choroidal neovascularization presented with FTMH. Topical betamethasone, bromfenac, and blinzolamide treatments were started, and the FTMH was closed with visual improvement (20/32 to 20/20) after 5 weeks. (Case 2) In the right eye of a 55-year-old male with an axial length of 30.81 mm and lacquer cracks, subretinal hyperreflective material and FTMH developed. The above three drugs were started after anti-VEGF drug injection. Sixteen weeks later, the FTMH was closed with visual improvement (20/63 to 20/20). Nonoperative closure of FTMH has already been reported, but few in eyes with pathologic myopia. Our results suggest that nonoperative closure of FTMH associated with pathologic myopia under eye drops may be possible in some cases.

FULL-THICKNESS MACULAR HOLE CLOSURE WITH TOPICAL MEDICAL THERAPY.

To examine the efficacy and clinical characteristics of successful full-thickness macular hole closure with topical therapy. Retrospective case series of full-thickness macular holes managed by a single retinal physician (DS) diagnosed and treated from 2017 to 22. Of 168 patients with full-thickness macular holes, 71 patients were started on steroid, carbonic anhydrase inhibitor, and nonsteroidal antiinflammatory (NSAID) drops. 49 patients (mean 67 years, 59% women) were included in the analysis, and 22 patients were excluded for poor follow-up. In total, 7/49 were secondary post-PPV holes and 42/49 were idiopathic. In addition, 18/49 eyes (36.7%) achieved closure on topical therapy, of which 13 were idiopathic. Hole size was directly correlated with odds of closure: for every 10 μm decrease in size and odds of closure increased by 1.2× ( P = 0.001, CI 1.1-1.4). Average time to closure was 107.2 days (range 20-512 days) and was not correlated with hole size ( P = 0.217, CI -0.478 to +1.938). The presence of VMT was found to be inversely related to successful closure (OR 6.1, P = 0.029, CI 1.2-31.3). There was no significant difference in final best-corrected visual acuity for eyes undergoing primary pars plana vitrectomy versus those trialing drops before undergoing pars plana vitrectomy ( P = 0.318, CI -0.094 to +0.112). In the first study to date to report the overall efficacy and clinical characteristics of successful macular hole closure with topical therapy, drops achieved an overall closure rate of 36.7%, with higher efficacy in smaller holes and those without VMT. Rates of MH narrowing and reduction in central foveal thickness acted as predictors of effectiveness of drop therapy.

VISUAL OUTCOMES AFTER INTERNAL LIMITING MEMBRANE PEELING VERSUS FLAP IN THE CLOSURE OF FULL-THICKNESS MACULAR HOLES.

To examine postoperative outcomes of internal limiting membrane peeling (ILMP) versus flap (ILMF) in the closure of full-thickness macular holes. Retrospective chart review of patients who underwent pars plana vitrectomy and gas tamponade with ILMP or ILMF to close full-thickness macular hole at the Atrium Health Wake Forest Baptist from January 2012 to October 2022 with at least 3 months follow-up. Main outcome measures were type 1 primary full-thickness macular hole closure and postoperative best-corrected visual acuity in mean logMAR. One hundred thirty and 30 eyes underwent ILMP and ILMF, respectively. There were no significant differences in baseline characteristics between the groups. Ninety-six percent of ILMP eyes and 90% of ILMF eyes achieved primary hole closure ( P = 0.29). Among all eyes with primary hole closure, best-corrected visual acuity at 1 year was not different between the groups, but when stratified by lens status, it was superior in the ILMP versus ILMF group in pseudophakic eyes: the estimated least-squares mean best-corrected visual acuity (Snellen equivalent) (95% confidence interval) was 0.42 (20/50) (0.34, 0.49) in the ILMP group and 0.71 (20/100) (0.50, 0.92) in the ILMF group. Internal limiting membrane peeling and ILMF techniques yielded similarly high full-thickness macular hole closure rates. In pseudophakic eyes with primary hole closure, ILMF eyes had worse best-corrected visual acuity at 1 year.

CORRELATIONS BETWEEN SUSPENDED HYPERREFLECTIVE MATERIAL WITH THE MACULAR MICROSTRUCTURE AND SPONTANEOUS CLOSURE OF FULL-THICKNESS MACULAR HOLES.

To investigate the characteristics of spontaneously closed full-thickness macular holes (FTMHs) and to seek potential predictors for the spontaneous closure of FTMHs. In this retrospective cohort study, the clinical data and optical coherence tomography images were reviewed from 19 eyes with spontaneously closed FTMHs (spontaneous closure group) and 37 control eyes with FTMHs that were delayed for nonmedical reasons, but ultimately required surgery (control group). The term, suspended hyperreflective material, was defined as hyperreflective material suspended within the FTMHs observed via optical coherence tomography; the presence of suspended hyperreflective material was evaluated in these eyes. The median time from diagnosis to spontaneous closure of the FTMHs was 13.7 (range, 2.4-32.4) weeks in the spontaneous closure group. The mean diameter of FTMHs in the spontaneous closure group was significantly smaller than that in the control group (191.68 ± 70.57 vs. 401.68 ± 162.19 µ m, P < 0.0001). The incidence of vitreomacular traction was higher in the spontaneous closure group compared with the control group (9/19 vs. 5/37, P = 0.009, odds ratio [95% confidence interval], 5.76 [1.56-21.21]); in seven of the nine eyes with vitreomacular traction from the spontaneous closure group, spontaneous vitreomacular traction separation and subsequent FTMH closure was observed. Suspended hyperreflective material was observed in nine eyes (47%) from the spontaneous closure group and three eyes (8%) from the control group ( P = 0.001, odds ratio [95% confidence interval], 10.20 [2.31‒45.02]). Smaller diameters, vitreomacular traction, and presence of suspended hyperreflective material may be suggestive of the potential for spontaneous closure of FTMHs.

Surgery for idiopathic full-thickness macular holes within four months of symptom onset yields superior visual outcomes: Results from an Irish patient cohort.

To describe the anatomical, visual, and safety results of full-thickness macular hole (FTMH) repair surgery and determine factors influencing outcomes. A retrospective chart review was performed on all patients who underwent primary FTMH repair surgery by a single surgeon over a 3-year period. For comparisons, Snellen visual acuity (VA) was converted to logMAR equivalent. Anatomical hole closure, visual improvement, and final VA of ≤ 0.30 logMAR were the primary outcome measures. Twenty eyes of 19 patients were included. Mean patient age was 69years (range 55 to 80years) and 74% were female. Mean minimum linear diameter (MLD) was 440μm (range 170μm to 1200μm). Mean duration of symptoms before surgery was 16weeks (range 3 to 39weeks). 100% of eyes achieved successful anatomical FTMH closure. Mean VA improved from 1.03 ± 0.43 logMAR (Snellen 6/60) preoperatively to 0.35 ± 0.22 logMAR (Snellen 6/15) postoperatively (p = 0.0001). Patients with worse preoperative VA gained more vision than those with better preoperative VA (p = 0.01). Eyes operated on within 4months of symptom onset were more than twice as likely to achieve a postoperative VA of ≤ 0.30 logMAR (Snellen 6/12 or better) compared to eyes with a longer duration of symptoms (p = 0.03). FTMH repair surgery was safe and effective, with outcomes comparing favourably with published international studies. All patients benefited from surgery regardless of symptom duration, presenting VA or FTMH size. However, surgery performed within 4months of symptom-onset was particularly beneficial, highlighting the need for prompt referral and surgery.

Novel surgical technique for macular holes with basal diameter &gt;1000 μ

Abstract: Closure rate of full-thickness macular holes (FTMHs) with basal diameter &gt;1000 μ is known to be poor. Patients presenting with FTMH having a minimum basal diameter of &gt;1000 μ without any coexistent retinal morbidity were offered vitrectomy, internal limiting membrane peeling, retinal massage, and aspiration of subretinal fluid from the MH. Visual acuity (VA) and spectral-domain optical coherence tomography (SD OCT) assessments were performed at baseline, week 1 after surgery and at postoperative months 1, 3, 6, and 12. VA, type of hole closure, presence of ellipsoid zone, and external limiting membrane defect were monitored. The primary endpoint was type 1 anatomical hole closure. Secondary outcome measure was a change in VA from baseline to 6-month follow-up and persistent hole closure at the final follow-up of 12 months. The mean age was 67.1 ± 9.1 years. Seven eyes were pseudophakic, and two underwent combined phacoemulsification with MH surgery. The mean minimum basal diameter of FTMH was 1162.4 ± 161 μ. The mean duration of visual loss was 11.3 ± 1.93 months. Type 1 closure of FTMH was seen in all patients on SD OCT, on the 7th postoperative day. The mean presenting VA was 1.06 ± 0.1 Logarithm of the minimum angle of resolution (logMAR). Best-corrected visual acuity improved to 0.91 ± 0.09 logMAR at 1-month follow-up (P = 0.005) (95% confidence interval [CI]: 0.061–0.251), 0.63 ± 0.1 logMAR (P &lt; 0.001) (95% CI 0.339–0.527) at 3 months, and 0.55 ± 0.05 logMAR (P &lt; 0.001) (95% CI 0.414–0.609) at 6 months. All holes were found closed at the final follow-up of 12 months. This novel technique can help achieve better outcomes and raise the primary anatomical success rate of FTMH with basal diameter &gt;1000 μ.

NONSURGICAL RESOLUTION OF FULL-THICKNESS MACULAR HOLES WITHOUT VITREOMACULAR TRACTION.

The purpose of this study was to report a case series of full-thickness macular holes without vitreomacular traction that resolved without surgery. This study is a retrospective case series of 11 patients who demonstrated closure of full-thickness macular holes without surgical intervention. All full-thickness macular holes closed, with all patients having improvement in visual acuity. All but one of the cases had visual acuity better than 20/40 at last recorded visit. Most cases presented with associated epiretinal membrane (73%), cystoid changes (64%), defects <150 μ m (80%), and resolved within 2 months (91%). Topical anti-inflammatory drops were used in 7 of 11 cases, and dorzolamide was used in one case. Full-thickness macular holes can develop in eyes without the presence of vitreomacular traction. Topical therapy without vitrectomy may be particularly helpful in closure of full-thickness macular holes with associated cystoid macular edema. Holes with a lamellar hole component may spontaneously resolve as part of a retinal remodeling process.

Swept Source-Optical Coherence Tomography-Guided Facedown Posturing to Minimize Treatment Burden and Maximize Outcome after Macular Hole Surgery.

We evaluated the closure of full-thickness macular holes (MHs) the day after surgery in minimizing the burden and maximizing patient outcomes. Herein, 25-gauge pars plana vitrectomy, internal limiting membrane peeling, and fluid-gas (20% sulfur hexafluoride) were performed for the treatment. Patients were instructed to remain in the facedown position until the confirmation of MH closure, and the position was discontinued in cases where the closure was confirmed. In total, 43 eyes of 43 patients, whose average age was 69.7 ± 8.6 years, were enrolled in this study. We used swept source (SS)-optical coherence tomography (OCT) for the confirmation of MH closure for gas-filled eyes and used spectral domain (SD)-OCT for the reconfirmation of MH closure after the gas volume was reduced to less than half of the vitreous cavity. MH closure was confirmed in 40 eyes (93%, the closure group) on the next day after surgery. The time from surgery to SS-OCT imaging was 24.7 h. Although facedown positioning was terminated in cases where MH closure was confirmed, there were no cases in which the MH was re-opened afterward. The basal and minimum MH size was significantly larger in the non-closure group than that in the closure group (p = 0.027, p = 0.043, respectively). Therefore, checking with SS-OCT the day after surgery and terminating facedown positioning in cases where MH closure was confirmed would be a useful method, removing a great burden for the elderly without sacrificing the MH closure rate.

Spontaneous closure of full-thickness macular hole after pars plana vitrectomy for retinal detachment: evidence of ellipsoid zone restoration.

To describe a case of full-thickness macular hole (FTMH) occurred after pars plana vitrectomy (PPV) for a macula-sparing rhegmatogenous retinal detachment (RRD), which showed a spontaneous closure associated with outer retinal layers restoration. Case report. A pseudophakic 69-year-old man underwent PPV for a macula-sparing superior RRD in the right eye (RE). Best corrected visual acuity (BCVA) was 20/20 before surgery. Three weeks after treatment the patient complained about visual impairment, and a FTMH was detected at fundus examination as well as confirmed by optical coherence tomography (OCT) scan. The patient was scheduled for a repeated surgery, but FTMH spontaneously closed eighteen days after its occurrence as demonstrated at OCT showing only a point break of the ellipsoid zone (EZ) and Verhoeff membrane. The subsequent macular OCT scan showed a point-like irregularity at the Verhoeff membrane and regeneration of EZ, associated with a progressive improvement in BCVA. Forty-days after the FTMH occurrence, all the retinal layers were completely restored with a complete clinical recovery. FTMH formation and closure after macula-sparing RRD repair is a rare event that could be characterized by spontaneous and gradual anatomical restoration of the EZ associated with visual acuity improvement, underlying the retinal physiology recovery.

Medical Therapy for Large Idiopathic Full-Thickness Macular Holes.

To describe the characteristics and outcomes of eyes with idiopathic full-thickness macular holes (FTMH) that underwent initial medical management. This retrospective study included eyes with FTMH that were initially managed with one month of topical therapy. Eligible subjects were treated with dorzolamide 2% three times a day, nepafenac 0.1% twice a day, and prednisolone acetate 1% four times a day. The primary endpoints was hole closure at one month and secondary endpoint was change in best-corrected visual acuity (BCVA). Ten subjects (mean age: 62.80 years; female: 50%) with unilateral FTMH were studied. The mean basal diameter of the entire cohort at baseline was 824.1 µm (median 828 µm). Four (40%) of the smaller holes (mean 698 µm; median 698.50 µm) closed after one month of topical therapy, whereas larger holes (mean 908.17µm; median 889.50 µm) did not close. In one eye, the hole reopened 4 months after stopping the medication, but closed again at one month after re-starting the topical treatment. Median BCVA improved from 0.35 logMAR at baseline to 0.05 logMAR in eyes that closed but remained at 0.70 logMAR at one month in eyes that did not close. Topical corticosteroid, non-steroidal anti-inflammatory, and carbonic anhydrase inhibitor therapy may promote closure of small FTMHs, but large holes are less likely to respond. One month of topical therapy might avoid subjecting some patients to complex vitreo-retinal surgery without compromising visual outcomes. Macular hole may re-open after stopping the topical therapy.

A Case of Full-thickness Macular Hole Formation Secondary to Laser Retinopexy

Purpose: To report a case of full-thickness macular hole (FTMH) formation secondary to demarcation laser retinopexy in a retinal break with localized retinal detachment patient.Case summary: A 59-year-old male visited our clinic with ocular discomfort in both eyes. Uncorrected visual acuity (UCVA) was 0.63 in right eye. Large retinal break in 1:30 o/c, localized retinal detachment and laser marking scars all around the right eye were found in fundoscopic exam. Posterior-vitreous detachment or vitreomacular traction was not observed in optical coherence tomography (OCT). Demarcation laser retinopexy was performed around the margin of retinal detachment and peripheral degenerative lesions. Three months after demarcation laser retinopexy, UCVA in right eye of the patient was decreased to 0.16 and full thickness macular hole was observed on OCT examination. Pars planar vitrectomy, internal limiting membrane peeling, and SF6 gas tamponade were performed in the right eye. One month after the surgery, closure of FTMH was observed. Three months after surgery, there were no recurrence of FTMH in the right eye.Conclusions: Demarcation laser photocoagulation of localized retinal detachments may predispose to FTMH formation. Even though it can be occurred rarely, follow-up check-up is necessary in consideration of the possibility of FTMH, which can cause serious visual loss.

Unique Optical Coherence Tomography Imaging in Spontaneous Closure of Full Thickness Macular Hole Post Laser Photocoagulation

Purpose: To study events in spontaneous full thickness macular hole (FTMH) closure following laser photocoagulation (LP). Methods: Retrospective case study of a patient of spontaneous FTMH closure documented by SD-OCT following laser. Results: A 51-year-old lady presented with FTMH and a subclinical retinal detachment (RD) in her right eye. LP for subclinical RD was done and surgery for FTMH was advised. On day of surgery, repeat SD-OCT showed spontaneous closure of FTMH with an outer retinal defect, following which surgery was abandoned. Conclusion: Spontaneous PVD induction relieves antero-posterior traction and Inner limiting membrane (ILM) micro breaks relieves tangential traction, which can result in spontaneous closure of FTMH.

Spontaneous closure of full-thickness macular hole after intravitreal brolucizumab injection for neovascular age-related macular degeneration

Spontaneous closure of full-thickness macular hole after intravitreal brolucizumab injection for neovascular age-related macular degeneration

Using a commercial fibrin sealant (TISSEEL) as an adjuvant for full-thickness macular hole closure surgery: A case series

A retrospective interventional case series was performed to evaluate the anatomical and visual outcomes of macular hole surgery aided with TISEEL commercial fibrin sealant. Seven eyes of seven patients were included: three with a recurrent macular hole, one with a traumatic macular hole, and three with primary macular holes. All eyes underwent vitrectomy, internal limiting membrane peeling, fluid air exchange, instillation of 1–2 drops of the commercial fibrin sealant on the hole, and C3F8 gas injection. The macular hole was closed in all seven patients; they showed significant improvement in visual acuity and no ocular or systemic complications.

MACULAR BUCKLING COMBINED WITH VITRECTOMY AND INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE FOR MACULAR HOLES WITH MACULAR RETINOSCHISIS WITHOUT RETINAL DETACHMENT IN HIGH MYOPIA.

To investigate the outcomes of macular buckling combined with vitrectomy and inverted internal limiting membrane flap technique for highly myopic full-thickness macular hole (FTMH) with macular retinoschisis. Twenty-six eyes of 26 consecutive patients were retrospectively included. Twelve eyes underwent macular buckling alone (buckling group). Fourteen eyes underwent macular buckling and vitrectomy with an inverted internal limiting membrane flap technique (combination group). Patients were followed for at least 9 months. Rates of FTMH closure and macular retinoschisis resolution, best-corrected visual acuity gained at the final visit were evaluated. The mean follow-up time was 13.00 ± 3.16 months. FTMH closed in six eyes (50%) of the buckling group and 13 eyes (92.86%) of the combination group ( P = 0.026) at the final visit. The macular retinoschisis resolution rate was close between two groups (100% vs. 92.86%; P = 1.000). Both groups achieved significant improvement in best-corrected visual acuity (10.42 ± 17.25 and 16.36 ± 10.39 Early Treatment Diabetic Retinopathy Study letters; P = 0.014 and P < 0.001). The combination group achieved slightly more best-corrected visual acuity improvement, but the difference fell short of significance ( P =0.312). Combination of macular buckling and vitrectomy with the inverted internal limiting membrane flap technique could achieve a high FTMH closure rate and significant best-corrected visual acuity improvement in FTMH with macular retinoschisis.

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.

ASSOCIATION BETWEEN EPIRETINAL MEMBRANE, EPIRETINAL PROLIFERATION, AND PROGNOSIS OF FULL-THICKNESS MACULAR HOLE CLOSURE.

To demonstrate the effects of epiretinal membrane (ERM) and epiretinal proliferation on surgical outcomes for full-thickness macular hole. Nested case-control study with propensity score matching. Patients operated on for full-thickness macular hole between January 2011 and March 2020 were enrolled. The primary outcome was failure of the macular hole closure, and the secondary outcome was unfavorable hole closure (V or λ type closure) at 6 months after the surgery. Five hundred and thirty-four eyes of 534 patients met the inclusion criteria. After 1:1 propensity score matching (127 pairs), patients demonstrating ERM were more likely to have a failure of hole closure (adjusted odds ratio, 2.71; 95% confidence interval, 1.19-6.14) and unfavorable hole closure (adjusted odds ratio, 2.07; 95% confidence interval, 1.16-3.71). Epiretinal membrane spanning the hole margin (hole marginal ERM) greatly increased the likelihood of unfavorable hole closure (adjusted odds ratio, 2.13; 95% confidence interval, 1.12-4.07). Patients with hole marginal-ERM + epiretinal proliferation were more likely to have a failure of hole closure (38.4%) compared with those with no ERM (11.8%). Patients with ERM had a higher risk for adverse surgical outcomes for full-thickness macular hole closure. The location of the ERM relative to the macular hole and the presence of epiretinal proliferation might affect the surgical outcomes for full-thickness macular hole closure.

Послеоперационные особенности структуры фовеолярной области после хирургического лечения сквозных макулярных разрывов различными способами

Purpose. Comparative assessment of the retinal macular zone structure after surgical treatment of full-thickness macular hole (FTMH) by various methods. Material and methods. Patients with Gass stage III-IV FTMH were divided into 3 groups. Group 1 patients (20 eyes) underwent a standard operation (subtotal vitrectomy (sVE), aspiration convergence of the FTMH edges, gas-air tamponade of the vitreous cavity). Patients in group 2 (20 eyes), after sVE and ILM peeling, autologous conditioned plasma (ACP) were applied to FTMH area followed by air tamponade. Patients of group 3 (20 eyes) after sVE underwent FTMH closure using an inverted ILM flap with the rupture edges approached, followed by air tamponade. Results. The increase in BCVA after 1 month averaged from 0.23±0.1 to 0.41±0.13, (p&lt;0.05) in patients in group 1, in group 2 from 0.15±0, 07 to 0.75±0.09, (p&lt;0.05), in patients in group 3 from 0.14±0.05 to 0.78±0.08, (p&lt;0.05). Anatomical results: in group 1, 17 patients who received standard surgical treatment, a month after surgery, had a satisfactory anatomical result (complete closure of the FTMH with restoration of the correct retinal architectonics in the foveal zone). In 3 patients, additional endovitreal intervention was required with successful FTMH closure. In all patients in group 2, according to OCT data, 5 days after the operation, hyperreflective tissue was detected in the FTMH area ("platelet plug"). When OCT was performed 1 month later, in all cases, the platelet plug resolved, and in all cases, restoration of the foveal profile architectonics was observed. In group 3, the closure of the FTMH on the 5th day of observation was recorded in all patients. When performing OCT after 1 month, complete closure of the neuroepithelium layer was recorded in all cases: in 13 patients - U-shaped closure and in 7 cases – V-shaped. The functional results in both groups were comparable; there was no statistical difference between them. Conclusion: The data obtained demonstrate the morphological features of the retinal foveolar zone postoperative restoration. There was no significant difference in functional results between study groups. Key words: full-thickness macular hole, vitreoretinal surgery, internal limiting membrane, inverted ILM flap, autologous conditioned plasma, optical coherence tomography.

Combination of Inverted ILM Flap Technique and Subretinal Fluid Application Technique for Treatment of Chronic, Persistent and Large Macular Holes.

IntroductionThe choice of surgical treatment for chronic, persistent and large full-thickness macular holes (FTMH) continues to be undefined and challenging, as some of these cases remain refractory to the treatment. We report the efficacy of combination of inverted internal limiting membrane flap technique (IILMFT) and subretinal application of the fluid (SR fluid application) technique for treatment of refractory FTMHs.MethodsNine patients (nine eyes) were enrolled into this retrospective non-randomized exploratory consecutive case series study. All patients were diagnosed with chronic, persistent or large FTMH and were treated with a combination of IILMFT and SR fluid application technique. The following outcome parameters were analysed during 1- and 6-month follow-up visits: anatomical FTMH closure rate on spectral domain optical coherence tomography (SD-OCT), best-corrected visual acuity (BCVA), degree of postoperative retinal displacement.ResultsThe mean preoperative diameter of FTMH was 542.0 μm (range 154–1930 μm). Final closure of FTMH was achieved in nine of nine cases (100%). In one case a second operation was required because of postoperative rhegmatogenous retinal detachment. The mean BCVA after the FTMH closure increased from 1.0 logMAR (0.7–1.3) to 0.4 logMAR (0.2–0.8 logMAR) (W = 2.67; p = 0.008). A positive correlation was revealed between preoperative BCVA and axial length (ρ = 0.67, p = 0.048), between preoperative BCVA and duration of the symptoms (ρ = 0.818, p = 0.007), as well as between postoperative BCVA at 1-month follow-up and BCVA at 6-month follow-up (ρ = 0.821, p = 0.007).ConclusionCombination of IILMFT with SR fluid application technique for refractory FTMH surgery appears to be effective and safe. Improvement of anatomical and visual outcomes after the single surgery benefits from and is ensured by the advantages of both novel surgical approaches.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40123-021-00361-2.
