[Multimodal topographically oriented approach to the study of full-thickness macular holes]. / Mul'timodal'nyi topograficheski orientirovannyi podkhod k izucheniyu skvoznykh makulyarnykh razryvov.

PURPOSE: This article studies the relationship between structural changes according to the findings of optical coherence tomography (OCT) and OCT angiography (OCTA), microperimetry (MP), multifocal electroretinography (mfERG) parameters in topographically corresponding areas of the macular region in idiopathic full-thickness macular holes (FTMH). MATERIAL AND METHODS: OCT, OCTA, MP and mfERG were performed in 14 eyes with FTMH stages I-IV according to Gass. In 13 points at a distance of 0-2.5°, 2.5-5.0°, and 5.0-10.0° from the fixation point, the light sensitivity (LS), amplitude and latency of the P1 component were compared with the size of the hole, the area of cystic changes (CC) at the level of the inner nuclear layer (INL) and the outer plexiform layer and Henle fiber layer complex (OPL+HFL), vessel density in the superficial and deep capillary plexus (SCP and DCP). RESULTS: LS and P1 component amplitude were significantly reduced at a distance of up to 5.0° from the fixation point. LS correlates with the apical and basal diameter of the hole (R> -0.53), the area of CC in the INL (R> -0.62) and the OPL+HFL complex (R> -0.55), the density of vessels in the SCP at a distance of up to 2.5° from the fixation point (R>0.51) and in the DCP at a distance of up to 5° from the fixation point (R>0.49). The P1 amplitude correlates with the basal diameter of the hole (R= -0.38), the area of CC in the INL and the OPL+HFL complex (R> -0.33) and vessel density in the SCP (R=0.37) at a distance of up to 2.5° from the fixation point, as well as vessel density in the DCP at a distance of up to 5° from the fixation point (R=0.47). Vessel density in the DCP is significantly lower in the presence of CC in the retina (p<0.001). CONCLUSION: In FTMH, there is a relationship between bioelectrical activity and LS, and structural disorders, capillary perfusion in different layers of the retina. A multimodal topographically oriented approach allows studying the relationship between structural and functional parameters in individual points of the retina and can be used in monitoring of FTMH after surgical treatment.

Long-term Follow-Up and Regeneration of Retinal Pigment Epithelium (RPE) after Tears of the Epithelium in Exudative Age-Related Macular Degeneration (AMD).

BACKGROUND: The goals of this study are to evaluate potential long-term visual deterioration associated with retinal pigment epithelial (RPE) tears in patients with neovascular age-related macular degeneration (nAMD) and to find treatment-related and morphological factors that might influence the outcomes. PATIENTS AND METHODS: This retrospective study enrolled 21 eyes of 21 patients from the database of Vista Eye Clinic Binningen, Switzerland, diagnosed with RPE tears, as confirmed by spectral domain optical coherence tomography (SD-OCT), with a minimum follow-up period of 12 months. Treatment history before and after RPE rupture with anti-VEGF therapy, visual acuity, and imaging (SD-OCT) were analyzed and statistically evaluated for possible correlations. RESULTS: Mean patient age was 80.5 ± 6.2 years. The mean length of total follow-up was 39.7 ± 13.9 months. The mean pigment epithelial detachment (PED) height increased by 363.8 ± 355.5 µm from the first consultation to 562.8 ± 251.5 µm at the last consultation prior to rupture. Therefore, a higher risk of RPE rupture is implied as a result of an increase in PED height (p = 0.004, n = 14). The mean visual acuity before rupture was 66.2 ± 16.0 letters. Mean visual acuity deteriorated to 60.8 ± 18.6 letters at the first consultation after rupture (p = 0.052, n = 21). A statistically nonsignificant decrease in vision was noted in the follow-up period. After 2 years, the mean BCVA decreased by 10.5 ± 23.7 ETDRS letters (p = 0.23, n = 19). PED characteristics before rupture and amount of anti-VEGF injections after rupture did not affect the visual outcome. None of the 21 patients included in our study showed a visual improvement in the long-term follow-up. RPE atrophy increased significantly from 3.35 ± 2.94 mm2 (baseline) to 6.81 ± 6.25 mm2 over the course of 2 years (p = 0.000 013, n = 20). CONCLUSIONS: The overall mean vision decrease after rupture was without statistical significance. There was no significant change in BCVA at the 2-year follow-up, independent of the amount of anti-VEGF injections provided. In this study, there was a significant increase in RPE defect over a follow-up of 2 years, implying progression of contraction of RPE and/or macular atrophy.

Closure Grading and Visual Outcome in Patients with Large Idiopathic Macular Holes: A Spectral-Domain Optical Coherence Tomography Observation.

INTRODUCTION: So far, there has been no closure grade system synthesizing morphological and microstructural features for large idiopathic macular holes (IMHs) treated by vitrectomy and internal limiting membrane (ILM) peeling. This study aimed to propose a concise one and explore its relevance with visual acuity and the related preoperative factors. METHODS: Consecutive patients with large IMHs (minimum diameter >400 µm), undergoing vitrectomy and ILM peeling, obtaining primary closure and regularly followed-up were enrolled. Preoperative clinical charts and spectral-domain optical coherence tomography (SD-OCT) parameters were reviewed. SD-OCT images and best corrected visual acuity (BCVA) were assessed at 1, 4, and 10 months postoperatively. SD-OCT features at last visit were categorized by BCVA significance, and preoperative risk factors were analyzed. RESULTS: Sixty-eight eyes from 64 patients were enrolled. The 10-month postoperative SD-OCT images were categorized into closure grade 1, 2, and 3 with successively decreased BCVA (p < 0.001). During early follow-up, part of grades 2 and 3 could evolve into the upper grade, respectively, but grade 3 could never evolve into grade 1 and exhibited the least satisfactory long-term BCVA. Binary logistic regression showed that large minimum linear diameter (MLD) was a risk factor for grade 3 occurrence (p < 0.001), with a cutoff value of 625.5 µm from the receiver operating characteristic curve for MLD predicting grade 3 occurrence (p = 0.001). CONCLUSION: Long-term closure status of large IMHs could be categorized into three grades with BCVA significance. Large horizontal MLD is a risk factor for occurrence of grade 3 closure with unsatisfactory visual recovery.

LENS CAPSULAR FLAP TRANSPLANTATION AS PRIMARY TREATMENT FOR CLOSURE OF LARGE MACULAR HOLES.

PURPOSE: To report the long-term outcomes of lens capsular flap transplantation (LCFT) as initial treatment for large macular holes (MHs). METHODS: Thirteen consecutive eyes with large MHs who received LCFT as primary treatment were reviewed retrospectively. All enrolled eyes underwent standard 23-gauge vitrectomy, internal limiting membrane peeling, LCFT, and 15% perfluoropropane tamponade. Autologous whole blood was applied in selected eyes to make the LCT intact. A face-down position maintained for 2 weeks postoperatively. Data including demographic information, medical history, anatomical and functional outcomes, and complications were recorded. RESULTS: The mean preoperative MHs diameter was 979.42 ± 388.28 µm. Eight eyes received autologous LCFT, and the other five eyes received allogenic LCFT. Whole blood was applied in seven eyes. The mean follow-up duration was 19.57 ± 6.24 months (range: 12.0-32.2 months). The macular hole was successfully closed in all cases (13/13). The median best-corrected visual acuity improved from 1.76 (interquartile range, 1.23-1.91) logarithm of the minimum angle of resolution (median Snellen acuity: 20/1,150) preoperatively to 1.16 ± 0.47 logarithm of the minimum angle of resolution (mean Snellen acuity: 20/290) (P < 0.01) at the last visit. No severe complications were noted. CONCLUSION: Lens capsular flap transplantation may help to improve the closure rate and visual outcomes in large MHs, which could be an alternative method as primary treatment for large MHs.

Effect of inverted internal limiting membrane flap technique on small-medium size macular holes.

Inverted internal limiting membrane (ILM) flap technique was developed to achieve macular hole (MH) closure in large MH and refractory cases. In this study, we evaluate the effect of the technique for small-medium size MH. We recruited patients who underwent vitrectomy for small-medium size (< 400 µm) MH with either inverted ILM flap technique (flap group) or with conventional ILM peeling (peeling group). Using propensity score, 21 eyes of 21 patients in the peeling group were matched against 21 eyes of 21 patients in the flap group. We compared MH closure rate, postoperative visual acuity, and recovery of the external limiting membrane (ELM) and ellipsoid zone (EZ). The MH closure rate was not different between the two groups (flap vs peeling: 90% vs 100%, P = 0.49). Whereas there was no significant difference in visual acuity improvement between the two groups, the flap group showed more disruption of the ELM 3 months after surgery and of the EZ at 3 and 6 months after surgery (P = 0.02, P = 0.03, and P = 0.04, respectively). The result suggested that inverted ILM flap technique does not have additional benefits for small-medium size MHs and may delay recovery of retinal integrity.

The efficacy and safety of ocriplasmin for patients with vitreous macular traction.

PURPOSE: To estimate the efficacy and safety of ocriplasmin for patients with vitreous macular traction (VMT). METHODS: The PubMed, EMBASE and Ovid were searched up to May 2020 to identify related studies. Statistical analysis was conducted by R software version 3.6.3. Results in proportion with 95% confidence interval (CI) were calculated by means of Freeman-Tukey variant of arcsine square transformation. RESULTS: The pooling results indicated the overall complete release rate was 50% (95% CI [45%-54%]). For VMT patients younger than 65 years old, with smaller adhesion size of VMT (<1500 µm), phakic eyes, with macular hole (MH) and subretinal fluid (SRF), while without epiretinal membrane (ERM), ocriplasmin could achieve much higher complete release rates than those under opposite conditions. The general nonsurgical closure rate of MH was 34% (95% CI [30%-37%]), and it was positively correlated with the MH size. The visual improvement rate was 45% (95% CI [32%-59%]), and it was higher for patients with VMT resolution (59%, 95% CI [41%-75%]). The secondary pars plana vitrectomy (PPV) rate for patients without MH closure or VMT resolution was about 31% (95% CI [23%-39%]). The incidence of MH progression was 10% (95% CI [4%-18%]), and other severe adverse events such as endophthalmitis, retinal detachment and retinal tear were relatively rare. CONCLUSION: Ocriplasmin is an effective, reliable and relatively safe intervention for the treatment of VMT. The most suitable candidates were patients younger than 65 years old, with smaller adhesion size (<1500 µm), phakic eyes, with MH and SRF, while without ERM.

RESTORATION PROCESS OF THE OUTER RETINAL LAYERS AFTER SURGICAL MACULAR HOLE CLOSURE.

PURPOSE: To investigate the interrelationship among the outer retinal layers after macular hole surgery and elucidate the restoration process. METHODS: This retrospective observational study included 50 eyes of 47 consecutive patients with closed macular holes in the first vitrectomy. Optical coherence tomography was obtained before surgery; at 1, 3, and 6 months postsurgery; and at the last visit. The complete continuous layer rate and mean defect length were evaluated for the outer nuclear layer (ONL), external limiting membrane (ELM), and ellipsoid zone (EZ). RESULTS: At all postoperative visits, the complete continuous layer rate was in the descending order of ELM, ONL, and EZ and the mean defect length was in the ascending order of ELM, ONL, and EZ. External limiting membrane was necessary for ONL restoration. External limiting membrane and ONL were necessary for EZ restoration. Hyperreflective protrusions were observed from the area lacking ELM into the subretinal space after surgery. Ellipsoid zone was not formed in coexistence with the hyperreflective protrusions. Intermediate reflective protrusions appeared under the ONL plus ELM after surgery and were eventually replaced by EZ. CONCLUSION: Restoration of the outer retinal layers after surgical macular hole closure occurs in the order of ELM, ONL, and EZ.

EN-FACE IMAGING OF ATYPICAL EPIRETINAL TISSUE IN LAMELLAR MACULAR HOLE.

PURPOSE: To elucidate the significance of en-face optical coherence tomography imaging of atypical epiretinal tissue (AET) in the lamellar macular hole (LMH). METHODS: This study involved 29 eyes of 29 patients who underwent surgical treatment for LMH with AET. Best-corrected visual acuity, metamorphopsia assessment (M-score), and optical coherence tomography were evaluated before and 6 months after surgery. The novel en-face optical coherence tomography parameters, such as the area of AET and hyperreflective fringe, were correlated with clinical factors before and after LMH surgery. RESULTS: Preoperatively, hyperreflective fringe was noted in 25 (86.2%) patients. The splitting of the inner retina, disruption of the ellipsoid zone, the extent of foveal cavitation, symptom duration, and change in best-corrected visual acuity were correlated with the area of AET (all P < 0.05). Multivariate regression analysis revealed that a larger area of AET was associated with longer symptom duration and less improvement in postoperative vision (all P < 0.05). CONCLUSION: The area of AET may represent the chronicity of LMH and is significantly associated with visual outcomes after LMH surgery. This novel en-face optical coherence tomography parameter can be used as a predictive factor for surgical outcomes in LMH with AET.

INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE WITHOUT POSTOPERATIVE FACE-DOWN POSITIONING FOR MACULAR HOLE REPAIR.

PURPOSE: To describe the outcomes of the inverted internal limiting membrane flap technique without postoperative face-down positioning for macular hole (MH) closure. METHODS: This retrospective longitudinal study identified patients who had undergone surgical repair for large (>400 µm), idiopathic MHs and did not maintain face-down positioning postoperatively. Outcome measures included anatomical success, defined as confirmation of hole closure by the optical coherence tomography scan and functional success and defined as improved best-corrected visual acuity from baseline at the last follow-up. RESULTS: Of the 63 eyes enrolled in the study, 94% patients (59 of 63) achieved anatomical success and 91% patients (57 of 63) achieved functional success. Fifteen (15) of these patients presented with a MH >600 µm. This subgroup achieved an anatomical success rate of 93% and a functional success rate of 87%. Statistically significant improvement in best-corrected visual acuity was demonstrated for all subgroups of MH size (P < 0.001). CONCLUSION: We report a high success rate of large, idiopathic MH closure with the inverted internal limiting membrane flap technique without postoperative face-down positioning. The results described in this study are favorable. However, larger studies with prospective design are warranted to explore this further.

CLINICAL ASSOCIATIONS AND PROGNOSTIC IMPLICATIONS OF REPAIR TISSUE PROLIFERATION IN EYES WITH RETINAL PIGMENT EPITHELIUM TEARS.

PURPOSE: To investigate demographic and clinical factors influencing the longitudinal changes of retinal pigment epithelium (RPE) dehiscence area after RPE tears, including the presence of RPE tear-associated repair proliferation (TARP), and identify factors associated with TARP development over follow-up. METHODS: Retrospective, single-center, observational cohort study of patients with a history of macular neovascularization and RPE tear. The area of RPE dehiscence was measured on repeated short-wavelength fundus autofluorescence imaging. Associations between covariates and RPE dehiscence areas were tested with multivariable linear mixed models. Associations between TARP development and clinical variables were investigated with Cox regression models. Factors associated with visual acuity changing rates were explored with linear mixed models. RESULTS: Thirty-seven eyes of 36 patients were included in this study and followed for a median time of 18 months. Tear-associated repair proliferation was identified in 27 eyes (73%). The median time for TARP detection was 112 days; none of the investigated factors was significantly associated with TARP occurrence. The presence of TARP (estimate: -0.042 mm2/month; P = 0.001) and female gender (estimate: -0.035 mm2/month; P = 0.006) were associated with slower rates of RPE dehiscence enlargement over time. Faster rates of visual improvement were observed in eyes with TARP compared with those without TARP (estimate = -0.010 logarithm of the minimum angle of resolution/month if TARP was present; P = 0.008). CONCLUSION: Retinal pigment epithelium tear repair with TARP and female gender were associated with slower RPE degeneration after RPE tears. The presence of TARP was associated better visual prognosis. Additional research on factors promoting TARP development may have therapeutic and prognostic implications.

MACULAR HOLE ASSOCIATED WITH AGE-RELATED MACULAR DEGENERATION: Pathogenesis and Surgical Outcomes.

PURPOSE: To ascertain the pathogenesis of macular hole (MH) associated with age-related macular degeneration (AMD) and its surgical outcomes. METHODS: Patients with full-thickness MH associated with AMD (higher grades than intermediate) were enrolled. The mechanism of MH formation and closure rate after vitrectomy (surgical outcome) were determined using optical coherence tomography imaging. RESULTS: The mechanism of MH formation (35 eyes) associated with AMD was classified into four types: vitreomacular traction (42.9%), gradual retinal thinning caused by subretinal drusen or pigment epithelial detachment (22.9%), massive subretinal hemorrhage (20.0%), and combined (14.3%). In the 41 eyes that underwent vitrectomy, the logarithm of the minimum angle of resolution best-corrected visual acuity improved from 0.82 (0.10-2.30) preoperative to 0.69 (0.10-2.30) postoperative (P = 0.001). Successful closure of the MH was achieved in 33 eyes (80.5%) after vitrectomy. No significant association was observed between the closure rate of MH after vitrectomy and mechanism of MH formation (P = 0.083). CONCLUSION: The mechanism of MH formation associated with AMD was classified into four types and was not related to its surgical outcome. Considering visual improvement and surgical outcome after vitrectomy in our study, active surgical treatment can be considered for MH associated with AMD.

FULL-THICKNESS MACULAR HOLE IN AGE-RELATED MACULAR DEGENERATION PATIENTS WITH TWO DISTINCT ENTITIES: A Multicenter Study.

PURPOSE: To describe optical coherence tomography characteristics of full-thickness macular holes (FTMHs) in age-related macular degeneration patients. METHODS: A multicenter, retrospective, observational case series of patients diagnosed with age-related macular degeneration and FTMHs seen between January 1, 2009, and January 3, 2020. Clinical charts and spectral-domain optical coherence tomography images were reviewed. Optical coherence tomography findings included FTMH-inverted trapezoid or hourglass appearance, central macular thickness (CMT), complete retinal pigment epithelium and complete retinal outer retinal atrophy, and presence of pigment epithelium detachment and epiretinal membrane. The mean outcome was the morphologic and functional characterization of different subtypes of FTMHs. RESULTS: A total of 86 eyes of 85 consecutive patients, with mean age of 80.31 ± 8.06 and mean best-corrected visual acuity of 1.17 ± 0.58 logarithm of the minimal angle of resolution. Two different subtypes of FTMHs were identified: tractional and degenerative. Fifty (58%) degenerative FTMHs characterized with inverted trapezoid appearance and 36 (42%) tractional FTMHs characterized with hourglass appearance. Degenerative FTMHs presented with 66% of CMT < 240 µm, 14% of CMT > 320, and 70% of complete retinal outer retinal atrophy, in comparison with 41% of CMT < 240 µm, 42.9% of CMT > 320%, and 20% of complete retinal outer retinal atrophy in the tractional FTMH group (P = 0.002, 0.003, <0.001, respectively). The presence of epiretinal membrane and pigment epithelium detachment where significantly higher in tractional FTMHs (P = 0.02, 0.03, respectively). CONCLUSION: Degenerative and tractional FTMHs may be two distinct clinical entities. Discerning degenerative from tractional FTMHs is possible by using optical coherence tomography features including shape of the FTMHs, CMT, internal-external ratio of FTMHs, and presence of complete retinal outer retinal atrophy, pigment epithelium detachment, and epiretinal membrane.

Outcome Of Recurrent Macular Hole Closure With Amniotic Membrane Plug.

BACKGROUND: The surgery of macular hole is a complex and intricate micro-surgery and chances of recurrence of macular hole are always high. Therefore, in order to provide a medium to close this hole, we carried out this research on subjects using amniotic membrane, in light of the studies being conducted around the world. This in turn led to benefitting the patients by improving their vision over time. PURPOSE: To assess the rate of recurrent macular hole closure with amniotic membrane plug. It was a Quasi-experimental study, conducted at Layton Rahmatullah Benevolent Trust (LRBT) Free Eye Hospital Karachi, from January 2019 to January 2020. METHODS: This study was conducted using 13 eyes of 13 patients with recurrent macular hole who underwent amniotic membrane plugging via pars plana approach. Outcomes measured were changes in best corrected visual acuity (BCVA) and change in hole size with the help of optical coherence tomography (OCT). RESULTS: Anatomic closure was attained in 100% of the cases whereas BCVA improved from 1.7±0.33 (6/300) to 0.9±0.15 (6/48). CONCLUSIONS: The use of AM is a functional method for management of large RMH.

Spontaneous Closure of Large Full-Thickness Macular Hole in a Patient with Degenerative Myopia: Case Report

Macular hole is characterized by a full-thickness defect of the retinal layers in the center of the fovea and is an important cause of central vision loss. Spontaneous closure of a macular hole is rare, most often occurring in traumatic and idiopathic macular holes. In this case report, we present a 51-year-old woman with a myopic macular hole that closed spontaneously. The patient had degenerative myopia and a history of clear lens surgery and multiple laser retinopexy procedures due to retinal tear in both eyes. A macular hole was detected in her right eye, but she declined surgery and was followed up. At 66 months after presentation, bridge formation and spontaneous closure of the macular hole were observed. Spontaneous closure is extremely rare in cases of myopic macular hole, but may be seen in patients who are followed for a long time.

Changes in each retinal layer and ellipsoid zone recovery after full-thickness macular hole surgery.

To analyze the changes in each retinal layer and the recovery of the ellipsoid zone (EZ) after full-thickness macular hole (FTMH) surgery. Patients who underwent surgery for FTMH were included. Spectral-domain optical coherence tomography (SD-OCT) was performed preoperatively and postoperatively at 1, 3, 6, 9, and 12 months. A total of 32 eyes were enrolled. Ganglion cell layer, inner plexiform layer, and inner nuclear layer showed significant reductions over time after surgery (P = 0.020, P = 0.001, and P = 0.001, respectively), but were significantly thicker than those of fellow eyes at 12 months postoperatively. The average recovery duration of the external limiting membrane (ELM), outer nuclear layer (ONL), and EZ was 1.5, 2.1, and 6.1 months, respectively. Baseline best-corrected visual acuity (BCVA) (P = 0.003), minimum linear diameter (MLD) (P = 0.025), recovery of EZ (P = 0.008), and IRL thickness (P < 0.001) were significant factors associated with changes in the BCVA. Additionally, axial length (P < 0.001), MLD (P = 0.020), and IRL thickness (P = 0.001) showed significant results associated with EZ recovery. The IRL gradually became thinner after FTMH surgery but was still thicker than that of the fellow eye at 12 months postoperatively. The recovery of ELM and ONL may be a prerequisite for the EZ recovery. The BCVA change was affected by baseline BCVA, MLD, recovery of EZ, and IRL thickness. Additionally, axial length, MLD, and IRL thickness were significantly associated with EZ recovery.

AUTOLOGOUS NEUROSENSORY RETINAL TRANSPLANTATION: Bridging the Gap.

PURPOSE: To review the autologous retinal transplantation surgical technique, indications, rationale, and current outcomes of data published to date. METHODS: Review of surgical technique, preoperative and postoperative best-corrected visual acuity, and macular hole (MH) closure rate in studies with at least five eyes. RESULTS: The weighted average macular hole closure rate is 88%, with a MH closure rate ranging from 66.7% to 100%. The weighted average best-corrected visual acuity improved from mean logarithm of the minimum angle of resolution 1.35 (Snellen equivalent of 20/450) preoperatively to mean logarithm of the minimum angle of resolution 1.02 (Snellen equivalent of 20/210) postoperatively. From the largest autologous retinal transplantation case series, 37% of patients gained 3 or more lines of visual acuity after autologous retinal transplantation for primary or refractory MHs and 74% gained 3 or more lines of visual acuity after autologous retinal transplantation for MH-retinal detachments. Functional improvement including negative Watzke-Allen sign and conversion from positive to negative scotoma was reported in large case series. CONCLUSION: Autologous retinal transplantation is a promising technique for closure of large and refractory MHs otherwise difficult to repair with conventional techniques. This technique may allow for replacement of neural tissue in the macula through cell rehabilitation and regeneration through presumed ectopic synaptogenesis, retinal progenitor cell differentiation and integration, and/or retinal progenitor cell material transfer to host neurons.

LONGITUDINAL ELLIPSOID ZONE DYNAMICS AFTER MACULAR HOLE REPAIR IN THE DISCOVER STUDY: Structure-Function Assessment.

PURPOSE: To evaluate association of the baseline macular hole (MH) geometric features and longitudinal ellipsoid zone integrity with the visual acuity outcome after surgical repair. METHODS: This was a post-hoc analysis of eyes in the DISCOVER study undergoing vitrectomy repair for MH. Anatomical and functional data were collected through one year postoperatively. An automated retinal layer segmentation platform was used for the assessment of outer retinal metrics and volumetric reconstruction of MH. Association of longitudinal ellipsoid zone features and baseline MH height, width, and volume with VA outcomes were investigated. RESULTS: Eighty-four eyes with MH were included. The mean baseline VA was 20 of 114 and increased to 20 of 45 (P < 0.001) at postoperative Month 12 (N = 45). Successful MH closure was achieved in 98.8% of cases. Ellipsoid zone integrity metrics significantly improved from baseline (P = 0.002) and postoperative Month 1 (P < 0.001) to post-operative Month 12. Ellipsoid zone metrics independently correlated with VA at all follow-up visits (P < 0.05). Increased baseline MH width and volume negatively correlated with the VA at postoperative Month 12 (P < 0.001). Preoperative VA and EZ integrity on optical coherence tomography were predictors for postoperative VA. CONCLUSION: Baseline MH volumetric parameters and EZ parameters were associated with VA outcomes after repair.
