    PURPOSE: To classify hypotony maculopathy (HM) using optical coherence tomography (OCT) findings and to investigate the associations among morphological types, clinical factors, and visual outcomes. METHODS: We retrospectively reviewed 60 eyes that developed HM after trabeculectomy. HM was classified according to the distribution and configuration of chorioretinal undulations on OCT B-scans. Between-group comparisons were performed, and factors associated with the morphological classification and logMAR best-corrected visual acuity (BCVA) at 3 months after HM onset (3-month BCVA) were determined. RESULTS: HM was classified into three OCT-based types by categorizing chorioretinal undulations as folds (U-shaped troughs) or spikes (V-shaped troughs): Type 1, folds only on vertical scans; Type 2, folds on both vertical and horizontal scans; Type 3, folds on both scans, with spikes. Axial length in Type 3 was significantly longer than that in Type 2 (P = 0.034). Subfoveal choroidal thickness was significantly thinner in Type 3 than in Types 1 and 2 (both P < 0.001). Minimum intraocular pressure (IOP) was significantly higher in Type 1 than in Types 2 and 3 (P < 0.001 and P = 0.003, respectively), with no difference between Types 2 and 3. In multivariable analysis using Type 1 as the reference group, minimum IOP was significantly associated with Type 2 (P = 0.001). For Type 3, both minimum IOP (P = 0.03) and subfoveal choroidal thickness (P = 0.02) showed significant associations. The 3-month BCVA was significantly worse in Type 3 than in Types 1 and 2 (P < 0.001 and P = 0.007, respectively). Chorioretinal spikes and preoperative BCVA were significantly associated with 3-month BCVA (both P < 0.001). Exploratory receiver operating characteristic analysis assessed the discriminative ability of subfoveal choroidal thickness for the presence of chorioretinal spikes (AUC = 0.876). A thickness of 195.0 μm was identified as a candidate cutoff value (sensitivity 92.3% and specificity 72.3%). CONCLUSIONS: In HM following TLE, chorioretinal spikes and preoperative BCVA are significantly associated with the 3-month BCVA. In HM, a thin subfoveal choroid (< 195.0 μm), may be associated with chorioretinal spikes, suggesting the need for careful postoperative IOP and OCT monitoring.

    PURPOSE: To investigate 6-month outcomes in eyes with neovascular age-related macular degeneration (nAMD) switched from intravitreal aflibercept 2 mg to intravitreal aflibercept 8 mg. STUDY DESIGN: Retrospective observational study. METHODS: We reviewed records of consecutive nAMD eyes switched from aflibercept 2 mg to 8 mg. In eyes continuing aflibercept 8 mg, best-corrected visual acuity (BCVA), treatment intervals, and anatomical/exudative parameters were evaluated at 6 months. In eyes that could not continue, reasons for discontinuation were examined. RESULTS: Forty-four eyes from 44 patients were included. At 6 months, 35 eyes (79.5%) continued and 9 (20.5%) discontinued aflibercept 8 mg. Discontinuing eyes had significantly shorter pre-switch treatment intervals and more frequent prior therapies than continuing eyes. In the continuation group, BCVA remained stable (median 0.05 to 0.00 logMAR, P = 0.351), while the treatment interval was significantly extended (median 7.0 to 9.0 weeks, P < 0.001). Central retinal thickness and pigment epithelial detachment height decreased significantly (P = 0.035 and P = 0.021, respectively). The proportion of eyes with subretinal fluid significantly decreased from 74.3 to 37.1% (P = 0.003). Of the discontinuations, 4 were due to worsening exudation and 5 to inability to extend to ≥8 weeks as required by labeling. No intraocular inflammation or serious adverse events occurred. CONCLUSIONS: Switching to aflibercept 8 mg achieved anatomical improvements and longer treatment intervals in ~80% of nAMD cases, suggesting it may be a useful alternative to aflibercept 2 mg. However, continuation may be difficult in refractory cases requiring frequent injections before switching.

    A 77-year-old man undergoing treatment for hepatocellular carcinoma (HCC) presented with blurred vision in his right eye, persisting for 2 months. Slit-lamp microscopy and fundus examination revealed inflammatory cells in the anterior chamber, severe vitreous opacities, and retinal vasculitis in the right eye. The patient underwent vitreous surgery with biopsy, and vitreous cytology confirmed a metastatic intraocular tumor originating from the HCC. Radiotherapy was administered to the right eye, with no recurrence of intraocular inflammation observed at 10 months post-irradiation.

    We investigated the treatment outcomes of patients aged ≥85 years with neovascular age-related macular degeneration (nAMD) who received anti-vascular endothelial growth factor (anti-VEGF) therapy using either treat-and-extend (TAE) or pro re nata (PRN) regimens for 1 year in real-world clinical practice. Eighty-five eyes from 85 patients were included. Among them, types 1, 2, and 3 macular neovascularization and polypoidal choroidal vasculopathy were present in 27.1%, 17.6%, 18.8%, and 36.5%, respectively. TAE and PRN regimens were used in 43.5% and 56.5% of patients, respectively. At baseline, the PRN group was older and had worse best-corrected visual acuity (BCVA), greater central retinal thickness, and more intraretinal fluid than the TAE group. In the TAE group, the mean number of injections was 7.6, BCVA improved significantly, and all retinal fluid rates decreased. In the PRN group, the mean number of injections was 3.9, BCVA remained unchanged, and the rates of macular fibrosis and atrophy increased. No serious adverse events were observed in either group. Anti-VEGF therapy was safe for patients aged ≥ 85 years with nAMD, and the TAE regimen effectively improved BCVA in this population. BCVA remained unchanged in the PRN-treated patients, with baseline disease severity and/or undertreatment potentially influencing the outcomes.

    A 76-year-old man presented with right eyelid swelling and deteriorated vision. Examination revealed anterior uveitis with hypopyon and a visual acuity of 20/2,000 in the right eye, with no abnormalities in the left. Computed tomography revealed enlargement of the right maxillary sinus and internal fluid accumulation, suggesting a postoperative maxillary cyst (POMC). Nasal endoscopic surgery drained the pus by opening the lower wall of the maxillary cyst. Following the procedure, intraocular inflammation resolved, and visual acuity in the right eye improved to 24/20. This is the first reported case of uveitis secondary to POMC.

    PURPOSE: To investigate the effect of Henle fiber layer hemorrhage (HFLh) on retinal sensitivity (RS) before and after displacement of the submacular hemorrhage (SMH) caused by retinal arterial macroaneurysm rupture. METHODS: This retrospective study included 31 eyes undergoing vitrectomy for SMH. Eyes were grouped based on the presence or absence of HFLh (HFLh [+/-] group). Retinal sensitivity was assessed in the fovea and in the area of the HFLh present preoperatively. RESULTS: The HFLh (+) and HFLh (-) groups had 21 and 10 eyes, respectively. Both groups showed improved postoperative foveal RS (both P < 0.05), which was significantly higher in the HFLh (-) group ( P = 0.02). In the HFLh (+) group, RS was significantly lower in the affected eye when compared with the fellow eye ( P < 0.01), whereas in the HFLh (-) group, no significant difference was noted between both eyes ( P = 0.58). Despite the significant improvement in the postoperative RS in areas with preoperative HFLh ( P < 0.001), it remained lower than the RS of the fellow eye ( P < 0.05). CONCLUSION: SMH displacement improved RS regardless of HFLh presence, although the degree of improvement was limited in the presence of HFLh.

    A 78-year-old woman presented with sudden vision loss and central scotoma. Visual acuity in the right eye was 20/222, with submacular hemorrhage (SMH) and Henle fiber layer hemorrhage (HFLh) due to retinal arterial macroaneurysm (RAM) rupture. She underwent SMH displacement, including cataract surgery, vitrectomy, intravitreal injection of tissue-plasminogen activator, and air tamponade. Three months postoperatively the SMH and HFLh had disappeared and visual acuity had improved to 20/200. Six months postoperatively, a macular hole had developed. We performed an inverted internal limiting membrane flap and gas tamponade. Ten months later, the hole had closed and visual acuity had improved to 20/100.

    PURPOSE: To identify a method for comparing preoperative axial length (AL) measurements with postoperative AL in submacular hemorrhage (SMH). STUDY DESIGN: Retrospective. METHODS: This study included 30 patients who underwent vitrectomy for SMH (January 2016-January 2023) with preoperative and postoperative AL data. Preoperative AL was obtained using ultrasonography for the affected eye (aUS-AL) and compared to those measured using optical biometry (OB) for the affected and fellow eyes (aOB-AL and fOB-AL, respectively). Postoperative AL (aPost-AL) was defined as the AL of the affected eye by OB. The absolute differences between the preoperative AL (aUS-AL, aOB-AL, and fOB-AL) and aPost-AL were assessed. RESULTS: aUS-AL, aOB-AL, and fOB-AL values were 23.50 ± 1.41 mm, 23.32 ± 1.40 mm, and 23.66 ± 1.45 mm, respectively, correlating strongly with aPost-AL (23.54 ± 1.37 mm) (all R > 0.95). fOB-AL exceeded aPost-AL significantly (P = 0.02). In all 30 eyes, absolute differences between preoperative AL and aPost-AL were 0.19 ± 0.18 mm, 0.28 ± 0.32 mm, and 0.21 ± 0.22 mm, respectively, which were not significantly different from each other (all P > 0.05). In nine eyes with SMH height > 1000 μm or unmeasurable, the absolute difference between aOB-AL and aPost-AL (0.42 ± 0.33 mm) exceeded that of aUS-AL and aPost-AL (0.10 ± 0.09 mm) (P = 0.003). CONCLUSION: Although aUS-AL, aOB-AL, and fOB-AL correlated well with postoperative AL in patients with SMH, fOB-AL may be measured longer and aOB-AL shorter in some cases. Therefore, aUS-AL may be considered primarily in determining IOL power of cataract surgery performed in combination with SMH displacement.

    PURPOSE: To analyze the pathophysiology of epiretinal membrane foveoschisis (FS) by evaluating the longitudinal changes in visual function and several optical coherence tomography parameters. METHODS: The medical records of 33 consecutive patients (35 eyes) with untreated epiretinal membrane foveoschisis were retrospectively reviewed. Best-corrected visual acuity, M-CHARTS score, and optical coherence tomography parameters including epiretinal membrane area, maximum depth of retinal folds, FS area, and FS circularity were evaluated. RESULTS: A wide range of FS area changes was observed at the final follow-up visit (59.68%-240.45% of the baseline FS area). In the FS enlargement group, best-corrected visual acuity and mean M-CHARTS scores significantly worsened and maximum depth of retinal folds significantly increased over time, whereas in the FS non-enlargement group, no significant change was observed in the best-corrected visual acuity, mean M-CHARTS scores, or maximum depth of retinal folds during the follow-up period. Multivariate logistic regression analyses revealed that maximum depth of retinal folds (odds ratio: 1.05, 95% confidence interval: 1.00-1.10, P = 0.048) and FS circularity (odds ratio: 0.91, 95% confidence interval: 0.83-1.00, P = 0.043) were significantly associated with FS enlargement. CONCLUSION: Epiretinal membrane foveoschisis encompasses diverse pathophysiologies. Since visual functions do not worsen in some cases, monitoring the changes in visual functions and retinal morphology over time is recommended to determine surgical indications.

    PURPOSE: To investigate the characteristics of mixed pathophysiologies in lamellar macular holes (LMHs) and related diseases using multimodal optical coherence tomography. METHODS: Overall, 126 eyes diagnosed with LMH, epiretinal membrane foveoschisis, or macular pseudohole using the horizontal B-scan image according to the definition proposed by Hubschman et al in 2020 were analyzed using multimodal optical coherence tomography imaging including horizontal and vertical 5-line B-scan, radial scan, and macular three-dimensional volume scan images. If at least two diagnostic criteria for LMH, epiretinal membrane foveoschisis, or macular pseudohole were satisfied in these scans, the patient was diagnosed as having a "mixed type." Retinal traction force was quantitatively evaluated by measuring the maximum depth of the retinal folds using en-face images. RESULTS: Mixed types constituted 34.1% of the cases. The LMH-related mixed group demonstrated intermediate characteristics between the epiretinal membrane foveoschisis/macular pseudohole and true LMH groups in terms of retinal traction and LMH-specific features and had a significant positive correlation between the maximum depth of the retinal folds and mean M-CHARTS scores (P = 0.034). CONCLUSION: A thorough optical coherence tomography analysis is necessary to accurately diagnose LMH and related diseases. A significant positive correlation was observed between the maximum depth of the retinal folds and the degree of metamorphopsia in the LMH-related mixed group.

    PURPOSE: To investigate the influence of submacular hemorrhage (SMH) at baseline on long-term visual outcomes of patients with typical age-related macular degeneration (tAMD) and polypoidal choroidal vasculopathy (PCV) treated with intravitreal aflibercept (IVA). METHODS: In this retrospective study, eyes of treatment-naïve patients with tAMD and PCV who initiated IVA under a treat-and-extend regimen and were followed up for ≥ 5 years were classified into the tAMD-SMH ( +), tAMD-SMH (-), PCV-SMH ( +), and PCV-SMH (-) groups based on the presence of SMH at baseline. Best-corrected visual acuity (BCVA) changes and macular fibrosis and atrophy incidences were assessed. RESULTS: This study included 127 eyes (127 patients), including 51 with tAMD and 76 with PCV; 18 eyes had SMH at baseline. In the tAMD-SMH ( +) group (n = 6), the mean logMAR BCVA significantly deteriorated from 0.59 ± 0.45 at baseline to 0.88 ± 0.47 at the final visit (P = 0.024). No significant BCVA changes were observed in the tAMD-SMH (-) (n = 45), PCV-SMH ( +) (n = 12), or PCV-SMH (-) (n = 64) groups (all P > 0.05). The tAMD-SMH ( +) group showed a significantly higher incidence of macular fibrosis at the final visit than did the tAMD-SMH (-) group (P = 0.042). There was no influence of baseline SMH on the macular fibrosis incidence in eyes with PCV and the macular atrophy incidence in eyes with tAMD and PCV. CONCLUSION: The presence of SMH at baseline resulted in poorer long-term visual acuity in eyes with tAMD, even with aflibercept treatment. However, no such influence was observed in eyes with PCV.

    A Japanese woman in her 70s was referred to our hospital for the evaluation and treatment of high intraocular pressure (IOP) in her right eye. She had undergone bilateral cataract surgeries and the insertion of hydrophilic acrylic intraocular lenses (IOLs). We performed trabeculotomy and trabeculectomy to lower her right IOP; thereafter, a circular opacity was observed on the right eye's IOL surface. We removed the right IOL because that eye's vision had decreased due to IOL opacification. The analysis of the removed IOL revealed that the main opacity component was calcium phosphate. This is the first post-glaucoma-surgery IOL calcification case report.

    PURPOSE: In cases of macular hole (MH) that is difficult to close, including large, chronic, or highly myopic cases, the inverted internal limiting membrane (ILM) flap technique is often preferred and yields favorable surgical outcomes as compared to those yielded by conventional ILM peeling. However, no consensus exists on the optimal location and area for peeling and inverting the ILM, since multiple alternative methods have been reported alongside the original method. Several adverse effects associated with ILM peeling have been documented, including mechanical impairment of the retinal nerve fiber layer and decreased retinal sensitivity. Particularly, when glaucoma is concomitant, the retinal nerve fiber layer is fragile, raising concerns about a decrease in retinal sensitivity. Consequently, in patients with large MH alongside glaucoma, the goal is to select a procedure that maximizes the closure rate of the MH while minimizing any negative impact on glaucomatous visual field impairment. However, a technique for this purpose has not yet been validated. OBSERVATIONS: A woman in her 60s presented with visual impairment (20/50), metamorphopsia, and central scotoma of unknown onset in the right eye. A full-thickness MH accompanied by epiretinal proliferation (EP) was identified, with a minimum diameter of 506 μm. Although a retinal nerve fiber layer defect was not evident on ophthalmoscopy, thinning of the ganglion cell complex (GCC), extending from the superotemporal aspect of the optic disc, was observed on optical coherence tomography. Both microperimetry and static visual field testing revealed reduced retinal sensitivity in the thinned GCC areas. A pars plana vitrectomy combined with cataract surgery was performed to address her condition. The EP was embedded into the foveal cavity. On the basis of the microperimetry results, the ILM within the absolute scotoma region was peeled on the superotemporal side of the fovea to create a flap, which was then placed over the MH. A gas tamponade was applied, and the patient was maintained in a prone position postoperatively. The MH was successfully closed after the surgery, resulting in visual improvement (20/25). No decline in retinal sensitivity after the surgery was observed. CONCLUSIONS AND IMPORTANCE: Determining the location and area of the inverted ILM flap on the basis of microperimetry results is a promising patient-tailored strategy for treating MH concomitant with glaucoma while preventing further ILM peeling-associated reduction in the retinal sensitivity.

    PURPOSE: To assess epiretinal membrane (ERM) formation, severity, and the associated risk factors after scleral buckling using en face optical coherence tomography (OCT) images. METHODS: Medical records of 61 consecutive patients (66 eyes) with rhegmatogenous retinal detachment who underwent scleral buckling were retrospectively reviewed. Posterior vitreous detachment (PVD) was determined based on B-scan OCT images. En face OCT images were used to visualize the ERM and retinal folds. ERM formation was identified by comparing en face images pre- and post-surgery. The maximum depth of the retinal folds (MDRF) was measured using en face imaging to objectively assess traction strength. RESULTS: ERM formation occurred in 15 (22.7%) eyes at the final visit; the foveal pit was preserved in all cases. Parafoveal retinal folds were present in 5 (7.6%) eyes, with a mean MDRF of 21.8 ± 12.6 µm. No significant difference was observed in best-corrected visual acuity (logarithm of the minimal angle of resolution) between the ERM formation (-0.019 ± 0.128) and non-ERM formation (-0.001 ± 0.213) groups at the final visit (P = 0.593; Mann-Whitney U test). Multivariate logistic regression analysis revealed that older age and the presence of PVD were significant risk factors for ERM formation (odds ratio 1.07, 95% confidence interval 1.01-1.14, P = 0.032; odds ratio 5.26, 95% confidence interval 1.06-26.10, P = 0.042; respectively). CONCLUSION: ERM occurred in 22.7% of cases but was mild and did not affect visual acuity. Older age and the presence of PVD are risk factors for ERM formation.

    BACKGROUND: Epiretinal membrane (ERM) causes visual impairment such as reduction in visual acuity and metamorphopsia due to retinal traction. With the improvement of optical coherence tomography (OCT) and microincision vitrectomy surgery (MIVS), the surgery of ERM has significantly advanced. However, there have been no large-scale studies on the following: (1) how to evaluate visual impairment in ERM, (2) the relationship between OCT findings and visual function, (3) when is the optimal timing of surgery, and (4) the relationship between the surgical instruments as well as techniques and prognosis. The purpose of this study was to obtain evidence regarding these ERM surgeries. METHODS AND DESIGN: This is a prospective, multicenter cohort study of ERM surgery in Japan from March 1, 2023, to March 31, 2027 (UMIN000048472, R-3468-2). Patients who underwent ERM surgery during the study period and agreed to participate in this study will be included. The goal is to have a total of 5,000 eyes surgically treated for ERM. The following data will be collected: age, gender, medical history, subjective symptoms, visual function before and 6 and 12 months after surgery, clinical findings, OCT data, surgical technique, instruments used in surgery, and complications. DISCUSSION: The results of this study will support the surgical decisions and procedures in ERM practices.

    PURPOSE: To investigate the relationship between retinal traction force and impairment of the inner retinal layer in patients with epiretinal membrane (ERM). DESIGN: Nonrandomized, retrospective consecutive case series. PARTICIPANTS: Two hundred nine eyes of 201 patients with idiopathic ERM who underwent vitrectomy for idiopathic ERM were enrolled. METHODS: Retinal folds caused by ERM were visualized using en face OCT, and the maximum depth of retinal folds within the parafovea (MDRF) was measured. Focal macular electroretinogram (ERG) was used to measure the amplitude and implicit time of each component for the ERM eyes and the normal fellow eyes. B-scan OCT images were used to measure the thicknesses of the inner nuclear layer (INL) and outer nuclear layer (ONL) + outer plexiform layer (OPL). Expression of α-smooth muscle actin (α-SMA) in surgically removed ERM specimens was quantified by reverse-transcription polymerase chain reaction. MAIN OUTCOME MEASURES: We analyzed the relationship between MDRF and the relative amplitudes of focal macular ERG (affected eye/fellow eye), the relationships between MDRF and the mean INL thickness and ONL+OPL thickness, comparison of INL thickness and ONL+OPL thickness for each area when cases were classified according to MDRF localization in the ETDRS chart, and the relationship between MDRF and the relative expression of α-SMA in the ERM specimens. RESULTS: The MDRF significantly correlated with the relative amplitudes (affected eye/fellow eye) of b-waves and oscillatory potentials (r = -0.657, P = 0.015; r = -0.569, P = 0.042, respectively) and the mean INL thickness and ONL+OPL thickness (r = 0.604, P < 0.001; r = 0.210, P = 0.007, respectively). However, only the INL thickness progression rate was significantly correlated with the MDRF progression rate (r = 0.770, P < 0.001). On case stratification by localization of MDRF based on the ETDRS chart, in regions other than temporal regions, the INL thickness was significantly greater in regions with MDRF than in other regions. The MDRF significantly correlated with α-SMA expression in the ERM specimens (r = 0.555, P = 0.009). CONCLUSIONS: The findings suggest that ERM impairs the inner retinal layer in a traction force-dependent manner.

    PURPOSE: To investigate the involvement of retinal traction in the pathogenesis of lamellar macular hole (LMH) and related diseases based on OCT-based consensus definition. DESIGN: Retrospective, observational study. PARTICIPANTS: Seventy-two eyes with LMH, epiretinal membrane foveoschisis (ERM-FS), or macular pseudohole (MPH). METHODS: To quantitatively evaluate the involvement and strength of retinal traction in their pathogenesis, retinal folds were visualized with en face OCT imaging, and the maximum depth of the parafoveal retinal folds (MDRF) was measured. Metamorphopsia was quantified by measuring the minimum visual angle of dotted lines needed to cause it to disappear using M-CHARTS (Inami). MAIN OUTCOME MEASURES: Maximum depth of retinal folds and M-CHARTS scores. RESULTS: Of the 72 eyes, 26 were classified as having LMH, 25 as having ERM-FS, and 21 as having MPH. Parafoveal retinal folds were observed in 7 (26.9%) eyes with LMH, 25 (100%) with ERM-FS, and 21 (100%) with MPH. The MDRF (7.5 ± 17.6 μm) was significantly smaller in LMH than in ERM-FS (86.3 ± 31.4 μm) and MPH (74.5 ± 24.6 μm) (both P < 0.001), whereas no significant difference in MDRF between MPH and ERM-FS was observed (P = 0.43). A significant positive correlation between MDRF and M-CHARTS scores was observed in ERM-FS and MPH (P = 0.008 and 0.040, respectively) but not in LMH (P = 0.073). CONCLUSIONS: Retinal traction was significantly weaker in the LMH group than in the ERM-FS and MPH groups. The MDRF was significantly associated with the degree of metamorphopsia in the ERM-FS and MPH groups. These results provide insights into the diseases' pathophysiology and treatment strategy.

    A 23-year-old woman presented with a 1-month history of visual abnormalities in her right eye. A visual field test revealed temporal abnormalities in the right eye. Optical coherence tomography revealed an indistinct ellipsoid zone (EZ) on the B-scan image and hyporeflective areas in the EZ layer on the en face image in the right eye. We diagnosed the patient with acute zonal occult outer retinopathy. Visual field tests and B-scan images improved to almost normal at 6 months, but hyporeflective areas remained on the en face images. Thus, en face images may be more sensitive at detecting abnormalities in the outer retina than other modalities.

    PURPOSE: To investigate preoperative factors associated with simultaneous internal limiting membrane (ILM) peeling during epiretinal membrane (ERM) removal. STUDY DESIGN: Observational cross-sectional study. METHODS: We retrospectively reviewed 60 eyes with idiopathic ERM that underwent vitrectomy. The gap between the ERM and ILM was visualized using en face optical coherence tomography. The depth and width of the ERM-ILM gap at the initiation site of ERM removal were measured, and the relationship between preoperative factors including these parameters and simultaneous ILM peeling during ERM removal was investigated. RESULTS: The ILM was simultaneously peeled during ERM removal in 30 eyes, but not in the other 30 eyes. Age was significantly higher (P = 0.017) and the width of the ERM-ILM gap was significantly smaller (P < 0.001) in the simultaneous ILM peeling (+) group than in the simultaneous ILM peeling (-) group. Multivariate logistic regression analysis confirmed the width of the ERM-ILM gap as a significant negative predictor for simultaneous ILM peeling (odds ratio, 0.992; 95% confidence interval, 0.986-0.997; P = 0.003). Receiver operating characteristic curve analysis of the width of the ERM-ILM gap revealed that the optimal cutoff for predicting simultaneous ILM peeling was 187.1 µm. CONCLUSION: The small width of the ERM-ILM gap at the initiation site of ERM removal was significantly associated with simultaneous ILM peeling, indicating that the adhesion strength between the ERM and ILM at the initial ERM grasping site determines whether simultaneous ILM peeling will occur during ERM removal.
