Abstract
Purpose While secondary epiretinal membranes (ERMs) are well-documented postoperative complications following rhegmatogenous retinal detachment (RRD) surgery, literature addressing the mechanisms of spontaneous resolution, particularly in cases involving vitrectomy, remain limited. In this case report, we describe the spontaneous resolution of secondary ERM in an amateur boxer following traumatic RRD surgery. Observations Pars plana vitrectomy was performed for traumatic RRD in a 20-year-old man. Secondary ERM formation was observed one month after RRD surgery, resulting in retinal distortion. The ERM began to peel spontaneously and disappeared one year after surgery. His visual function did not deteriorate in the meantime. Conclusions and Importance Spontaneous ERM separation is possible even after vitrectomy. This is the first published observation of the formation and spontaneous disappearance of secondary ERM after vitrectomy without intervention.

Abstract
ABSTRACT Radial keratotomy (RK) was commonly performed in the 1980s and 1990s. We aimed to clarify the current status of post-RK refractive correction and treatment. We retrospectively reviewed the charts of 70 patients with a history of RK. Of the 70 patients, 44 were identified for clinical outcomes. Refractive or therapeutic intervention (rigid gas-permeable contact lens fit, spectacle prescription, corneal surgery, and use of pilocarpine hydrochloride for photophobia) was possible in 59% of patients with postoperative visual deterioration after RK; in the remaining 41%, therapeutic intervention was not possible. Rigid gas-permeable contact lens fit for corneal irregular astigmatism was the most common refractive intervention and was effective in 36% of cases in the university hospital.

Abstract
PURPOSE To evaluate the association between quantitative parameters derived from volume analysis of optical coherence tomography (OCT) data and disease worsening in Vogt-Koyanagi-Harada disease (VKHD) and sympathetic ophthalmia (SO). METHODS This retrospective study, conducted at Osaka University Hospital, employed swept-source OCT scans from patients diagnosed with VKHD or SO between October 2012 and January 2021. The choroidal vessel structure was segmented and visualized in three dimensions, generating quantitative vessel volume maps. Region-specific choroidal vessel volume (CVV), choroidal volume (CV), and vessel index (VI) were scrutinized for their potential correlation with disease severity. RESULTS Thirty-five eyes of 18 VKHD and 2 SO patient (8 females, 10 males) were evaluated. OCT-derived CVV maps revealed regional CV alterations in VKHD and SO patients. Two parameters, i.e. CV at 3- and 6-month follow-ups (p = 0.044, p = 0.040, respectively, with area under the ROC curve of 0.70) and CVV at 6 months (p = 0.046, area under the ROC curve of 0.71), were significantly higher in recurrent VKHD and SO compared to effectively treated cases. CONCLUSIONS The volume analysis of OCT images facilitates a three-dimensional visualization of choroidal alterations, which may serve as a reflection of disease severity in VKHD and SO patients. Furthermore, noninvasive initial CVV or CV measurements may serve as potential biomarkers for predicting disease recurrence in VKHD and SO.

Abstract
PURPOSE To report a case of corneal endothelial damage caused by alcohol-containing chlorhexidine gluconate (CG-A) and its progression over time. METHODS This was a case report. RESULTS A 22-year-old man underwent neurosurgery under general anesthesia. CG-A (1%) was used for disinfection after the application of corneal protection tape. Postoperatively, the patient presented with hyperemia and swelling of the left conjunctiva and was referred to our department. Initial examination revealed left corneal epithelial erosion and corneal edema, which improved on postoperative day 14. The corneal endothelial cell density (ECD) was 3,345 cells/mm2 on day 14, decreased rapidly to 2,090 cells/mm2 on day 42, and slowly reduced to 1,122 cells/mm2 on day 168. Thereafter, no decrease in ECD was observed. CONCLUSIONS CG formulations can lead to a persistent decrease in ECD over several months, even after improvement of acute corneal edema.

Abstract
In vertebrates, retinal neural circuitry for visual perception is organized in specific layers. The outer plexiform layer is the first synaptic region in the visual pathway, where photoreceptor synaptic terminals connect with bipolar and horizontal cell processes. However, molecular mechanisms underlying cone synapse formation to mediate OFF pathways remain unknown. This study reveals that Necl-1/CADM3 is localized at S- and S/M-opsin-containing cones and dendrites of type 4 OFF cone bipolar cells (CBCs). In Necl-1-/- mouse retina, synapses between cones and type 4 OFF CBCs were dislocated, horizontal cell distribution became abnormal, and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors were dislocated. Necl-1-/- mice exhibited aberrant short-wavelength-light-elicited signal transmission from cones to OFF CBCs, which was rescued by AMPA receptor potentiator. Additionally, Necl-1-/- mice showed impaired optokinetic responses. These findings suggest that Necl-1 regulates cone synapse formation to mediate OFF cone pathways elicited by short-wavelength light in mouse retina.

Abstract
BACKGROUND/AIMS We assessed the associations between retinopathy of prematurity (ROP) and continuous measurements of oxygen saturation (SpO2), and developed a risk prediction model for severe ROP using birth data and SpO2 data. METHODS This retrospective study included infants who were born before 30 weeks of gestation between August 2009 and January 2019 and who were screened for ROP at a single hospital in Japan. We extracted data on birth weight (BW), birth length, gestational age (GA) and minute-by-minute SpO2 during the first 20 days from the medical records. We defined four SpO2 variables using sequential measurements. Multivariate logistic regression was used to develop a model that combined birth data and SpO2 data to predict treatment-requiring ROP (TR-ROP). The model's performance was evaluated using the area under the receiver operating characteristic curve (AUC). RESULTS Among 350 infants, 83 (23.7%) required ROP treatment. The SpO2 variables in infants with TR-ROP differed significantly from those with non-TR-ROP. The average SpO2 and high SpO2 showed strong associations with GA (r=0.73 and r=0.70, respectively). The model incorporating birth data and the four SpO2 variables demonstrated good discriminative ability (AUC=0.83), but it did not outperform the model incorporating BW and GA (AUC=0.82). CONCLUSION Data obtained by continuous SpO2 monitoring demonstrated valuable associations with severe ROP, as well as with GA. Differences in the distribution of average SpO2 and high SpO2 between infants with TR-ROP and non-TR-ROP could be used to establish efficient cut-off values for risk determination.

Abstract
BACKGROUND Retinal nonperfusion is a significant cause of vision loss in patients with proliferative diabetic retinopathy (PDR). Therefore, reperfusion of a nonperfusion has been a matter of strong interest, but few previous studies have demonstrated the potential benefits of reperfusion. CASE REPORTS Here, we report longitudinal optical coherence tomography angiographic analysis of two cases of PDR, in which the retinal neovascularization (RNV) that developed in response to retinal ischemia formed anastomoses with pre-existing physiological retinal vessels, resulting in both superficial and deep capillary reperfusion within the nonperfusion. We named this interesting finding "neovascular-vascular anastomosis." Retinal reperfusion due to neovascular-vascular anastomosis differed from recanalization, defined as reperfusion of once-occluded blood vessels, and has not been reported previously. CONCLUSION Our observation highlights the potential of RNV to rescue retinal ischemia by the formation of neovascular-vascular anastomoses.

Abstract
PURPOSE We compared the 1-year surgical outcomes of microhook ab interno trabeculotomy (μLOT) using three types of microhooks. METHODS We retrospectively analyzed 81 eyes that underwent μLOT, in which three microhooks, the Sinskey hook, Tanito Micro-Hook-trabeculotomy-device (TMH), and Matsushita ed. TMH, were used. We collected the data from the medical records. We analyzed the success rates and risk factors. Failure was defined as the need for additional surgery for IOP reduction, loss of light perception, and IOP ≧22 mmHg and IOP reduction <20% (definition 1), IOP ≧17 mmHg and IOP reduction <20% (definition 2), IOP ≧15 mmHg and IOP reduction <25% (definition 3), or IOP ≧12 mmHg and IOP reduction <30% (definition 4) at two consecutive follow-up visits. RESULTS Twenty-six eyes underwent μLOT using the Sinskey microhook (group S), 21 eyes using the TMH (group T), and 34 eyes using the Matsushita ed. TMH (group M). The mean postoperative IOP and IOP-lowering medication score decreased significantly. The respective success rates among groups S, T, and M did not differ significantly (definition 1, 65.4%, 61.9%, and 55.9%; definition 2, 42.3%, 47.6%, and 32.3%; definition 3, 15.4%, 28.6%, and 23.5%; definition 4, 0%, 9.5%, and 2.9%). In group S, the hyphema-related IOP spikes decreased within 2 weeks postoperatively, and in group M, the non-hyphema-related IOP spikes decreased significantly. CONCLUSION The 1-year surgical outcomes and complications after μLOT did not differ significantly among the three microhooks. The differences in the microhook tips might be associated with postoperative transient IOP spikes.

Abstract
PURPOSE To report the efficacy of intraoperative optical coherence tomography in locating proliferative membranes or strands subretinally or preretinally during pars plana vitrectomy for proliferative vitreoretinopathy or old rhegmatogenous retinal detachment. METHODS After removing the vitreous and apparent epiretinal membranes, vitreous fluid was exchanged for perfluorocarbon. Lesions of the retinal folds or persistently detached retinas, suspected to be subretinal membrane lesions, were examined using intraoperative optical coherence tomography in three eyes with proliferative vitreoretinopathy. RESULTS Intraoperative optical coherence tomography showed subretinal or preretinal structures in all three patients. A subretinal structure with underlying fluid was removed through an intentional hole in a patient. In another patient, a subretinal structure without underlying fluid was not removed. In the remaining patient, the preretinal membranes detected with intraoperative optical coherence tomography could be peeled successfully. CONCLUSION Intraoperative optical coherence tomography examination with perfluorocarbon tamponade effectively identified the correct location of proliferative membranes or strands, namely, preretinal or subretinal. This imaging technique helps surgeons determine whether an intentional hole should be made to remove the subretinal structure during vitrectomy. Intraoperative optical coherence tomography, combined with perfluorocarbon tamponade, leads to safer and more effective surgery for proliferative vitreoretinopathy.

Abstract
Pluripotent stem cell-based therapy for retinal degenerative diseases is a promising approach to restoring visual function. A clinical study using retinal organoid (RO) sheets was recently conducted in patients with retinitis pigmentosa. However, the graft preparation currently requires advanced skills to identify and excise suitable segments from the transplantable area of the limited number of suitable ROs. This remains a challenge for consistent clinical implementations. Herein, we enabled the enrichment of wild-type (non-reporter) retinal progenitor cells (RPCs) from dissociated ROs using a label-free ghost cytometry (LF-GC)-based sorting system, where a machine-based classifier was trained in advance with another RPC reporter line. The sorted cells reproducibly formed retinal spheroids large enough for transplantation and developed mature photoreceptors in the retinal degeneration rats. This method of enriching early RPCs with no specific surface antigens and without any reporters or chemical labeling is promising for robust preparation of graft tissues during cell-based therapy.

Abstract
PURPOSE To investigate the prevalence, associated factors, and inter-eye differences of myopia and astigmatism in an adult Japanese population-based cohort. METHODS A total of 4282 participants from the Tohoku Medical Megabank Organization Eye Study (ToMMo Eye Study) underwent comprehensive ocular examinations as well as extensive physiological tests and a lifestyle questionnaire. The spherical equivalent (SE) and cylinder power were obtained as refractive parameters. The age- and gender-stratified prevalences of high myopia (SE < -5D), myopia (SE < -0.5D), hyperopia (SE > 0.5D), astigmatism (cylinder power < -0.5D), and anisometropia (SE difference >1D) were calculated. Multivariable analyses were performed to identify associated factors for refractive error (RE). Distribution and associated factors of the inter-eye difference in RE were also investigated. RESULTS The age-adjusted prevalence of high myopia, myopia, hyperopia, astigmatism, and anisometropia was 15.9%, 63.5%, 14.7%, 51.1%, and 14.7%, respectively. Both myopia and high myopia were more prevalent in the younger age group, while astigmatism was more prevalent in the older age group. Age, education, blood pressure, intraocular pressure, and corneal thickness are significantly associated with myopic refraction. Age, gender, intraocular pressure, and corneal thickness are correlated with astigmatism. Older age was associated with against-the-rule astigmatism. Older age, myopia, and longer education showed a significant correlation with large inter-eye differences in SERE. CONCLUSIONS This study demonstrated the high prevalence of myopia in young Japanese, which may be caused by a generational shift. This study also confirmed the influence of age and education on both the prevalence and inter-eye differences of RE.

Abstract
PURPOSE The aim of this study was to investigate the association between cytosine-thymine-guanine trinucleotide repeat (TNR) expansion in TCF4 and the clinical phenotypes of corneal densitometry or anterior segment morphology in Fuchs endothelial corneal dystrophy. METHODS This retrospective cross-sectional study included 150 eyes from 75 Japanese consecutive patients with Fuchs endothelial corneal dystrophy. Cytosine-thymine-guanine repeat expansion of leukocyte-derived genomic DNA was analyzed through fragment analysis using polymerase chain reaction and triplet repeat primed polymerase chain reaction. Scheimpflug-based densitometry and anterior segment optical coherence tomography were applied. Corneal densitometry, and corneal and anterior segment morphology parameters were compared between patients with and without TNR expansion of 50 or more (expansion and nonexpansion groups, respectively) using a mixed model. RESULTS The average age of the patients was 66.8 ± 13.0 years, and the modified Krachmer grading scale was 1, 2, 3, 4, 5, and 6 for 7, 32, 28, 51, 6, and 18 eyes, respectively. Sixteen patients (21%) exhibited ≥50 TNR expansion. No significant differences in sex, age, history of keratoplasty, modified Krachmer grade, and corneal densitometry in either diameter or depth were observed between the 2 groups. No significant differences in anterior segment morphology, including the anterior chamber depth and anterior chamber angle width parameters, were observed using a univariate mixed model, except for central corneal thickness (P = 0.047). However, according to the multivariate mixed model, repeat expansion was not significantly associated with central corneal thickness (P = 0.27). CONCLUSIONS No significant differences in clinical phenotypes were found between Japanese patients having Fuchs endothelial corneal dystrophy with and without TNR expansion.

Abstract
Intravitreal injection of aflibercept (IVA) has successfully treated polypoidal choroidal vasculopathy (PCV), and polyp morphology is an important indicator of treatment efficacy. However, many studies have not reported the presence or absence of polyp regression and treatment outcomes, and few studies have reported polyp reduction and treatment outcomes in cases with residual polyps. We retrospectively measured the polyp area on indocyanine green angiography images before and after the IVA loading phase and investigated the regression and reduction of polyps and treatment outcomes of 81 eyes with PCV treated with IVA. We investigated the relationship between the presence or absence of complete regression of polyps and the percentage change in the polyp area and treatment outcomes. Eyes with complete polyp regression had significantly better visual acuity improvements compared with baseline at 12 months (P = 0.0108), fewer treatments (P = 0.0024), fewer recurrences during 12-months follow-up (P = 0.0010), and more "dry maculas" at 3 months (P = 0.0048) than eyes in which polyp regression did not occur. A significant correlation was seen only between the percentage of polyp regression and visual acuity at 3 months (P = 0.0395). Regarding IVA therapy for PCV, the presence or absence of complete polyp regression at the end of the loading phase affected the treatment outcome, whereas the degree of polyp reduction in cases of residual polyps had no effect.

Abstract
BACKGROUND Recently, faricimab was approved as the new drug for neovascular age-related macular degeneration (nAMD). We lack the knowledge to choose between the existing drug and this new drug to use for treatment-naïve nAMD cases. In this study, we compared the functional and morphologic effects in loading dose between patients with treatment-naïve nAMD treated with either intravitreal aflibercept (IVA) or intravitreal faricimab (IVF) injection in a clinical setting. METHOD This retrospective study included 30 eyes of 28 patients who started treatment with IVA between June and September 2022 and 30 eyes of 29 patients who were administered IVF between October 2022 and March 2023. All patients received three monthly IVA or IVF. The best corrected visual acuity (BCVA), central retinal thickness (CRT), and the proportion of eyes with residual exudative change at baseline and 1,2, and 3 months after initial treatment were compared between the groups. RESULTS The mean BCVA significantly improved from pre-treatment after the loading dose in the IVA group (0.46 ± 0.46-0.36 ± 0.37, p = 0.0047) but not in the IVF group (0.46 ± 0.41-0.44 ± 0.45, p = 0.60). The mean CRT significantly improved in both groups. The proportion of eyes with residual exudative change was greater in the IVF group than in the IVA group 2 months after the first treatment (p = 0.026). The analysis of cases that achieved complete resolution of exudative changes after the loading dose showed that the IVA group had a significant improvement in the BCVA, whereas the IVF group did not (p = 0.0047 and 0.20, respectively). CONCLUSIONS Although both IVA and IVF significantly improved CRT, the BCVA improved significantly in the IVA group but not in the IVF group.

Abstract
Hexokinase 1 (HK1) gene is the cause of autosomal dominant retinitis pigmentosa (RP) 79. To date, only E874K mutation has been reported as the causative mutation in patients with nonsyndromic RP. As a Caucasian RP case with a pathological variant of HK1 exhibiting pigmented paravenous retinochoroidal atrophy (PPRCA) phenotype was recently reported, we reviewed RP79 cases in our Japanese RP cohort. Consequently, 2 Japanese patients, who were diagnosed with RP79 by genetic tests in our RP cohort, were included in this study. Patient 1 was a 60-year-old woman. Fundus examination revealed symmetrical donut-shaped retinal degeneration, with pigment deposition avoiding the macula. Moreover, degeneration extended in a peripheral direction along the vessels like a starfish, and degeneration was observed around the veins and arteries. Patient 2 was a 75-year-old man. Fundus examination revealed symmetric macula-avoiding donut-shaped retinal degeneration, with paravenous protruding degeneration along the blood vessels like in case 1. Both Japanese cases, which belonged to two separate families, had the same HK1 pathogenic mutation, with a phenotype of PPRCA. Furthermore, atrophy along retinal arteries was noted. Reviewing previous nonsyndromic RP79 cases revealed symptoms that are believed to be those of PPRCA. Ultra-widefield fundus imaging, especially ultra-widefield fundus autofluorescence, has been useful in detecting PPRCA. If these devices become widely available, more cases may be discovered in the future because PPRCA can be used as a clue to suspect RP79, and Sanger sequencing may be used to identify pathogenic mutations in HK1 at a lower cost and more easily than using whole-exome sequencing.

Abstract
OBJECTIVES To characterize higher-order aberrations (HOAs) in different severities of keratoconus (KC) from the anterior and posterior corneal surfaces and whole eye using an integrated Scheimpflug corneal tomographer/Hartmann-Shack wavefront aberrometer. METHODS This study included eyes with clinical KC, topographic KC (no clinical signs), fellow eyes with very asymmetric ectasia with normal topography and no clinical signs (VAE-NT), and control eyes. Corneal and ocular wavefront aberrations were obtained using an integrated Scheimpflug tomographer/Hartmann-Shack wavefront aberrometer. The diagnostic capability of distinguishing VAE-NT from the control was also tested. RESULTS This study included 68 eyes with clinical KC, 44 with topographic KC, 26 with VAE-NT, and 45 controls. Clinical KC had significantly greater total HOAs and coma from the anterior and posterior corneal surfaces and whole eye than the other groups ( P <0.05). Although topographic KC had significantly greater values in all wavefront parameters than the control ( P <0.05), ocular and corneal HOAs did not differ between the VAE-NT and control groups. The coma from the anterior cornea in topographic KC was significantly greater than that in VAE-NT ( P <0.05); the coma from the posterior cornea and whole eye did not differ. Total HOAs from the anterior corneal surface exhibited the highest area under the receiver operating characteristic curve value of 0.774 (sensitivity, 73%; specificity, 78%). CONCLUSION A comprehensive wavefront assessment can be used to quantitatively evaluate corneal and ocular HOAs across various severity of KC. Total HOAs from the anterior corneal surface exhibited the potential ability in distinguishing VAE-NT from the control eyes.

Abstract
Introduction Here, we present a case of full-thickness macular hole (FTMH) recurrence following two vitrectomies, accompanied by additional internal limiting membrane (ILM) peeling and gas tamponade. Ultimately, FTMH closure was accomplished by spontaneous retinal detachment around the macular hole and gas tamponade alone. Case Presentation The patient, a 54-year-old woman with a lamellar macular hole, had a visual acuity of 20/100 in her left eye. The treatment regimen included cataract surgery, a 25-gauge pars plana vitrectomy involving ILM peeling, application of the lamellar hole epiretinal proliferation embedding technique, and subsequent gas tamponade. Closure of the lamellar macular hole was observed a month post-surgery, improving visual acuity to 20/40. However, FTMH developed 3 months after the initial surgery, resulting in visual acuity decline to 20/100. A 25-gauge pars plana vitrectomy was performed with extensive ILM peeling and 20% sulfur hexafluoride gas tamponade. FTMH closure was noted within 19 days after reoperation, enhancing visual acuity to 20/66. Approximately 1.5 months after reoperation, a pinhole-shaped macular hole was identified, and the patient opted for follow-up observation due to her refusal to undergo additional surgery. As the macular hole gradually enlarged resembling retinal detachment, outpatient fluid-gas exchange with 14% perfluoropropane was performed 3.5 months after reoperation. The FTMH closed within a week post-gas injection and remained closed for more than 1 year. Consequently, visual acuity in the left eye was sustained at 20/50. Conclusion We encountered a case that might highlight the significance of releasing subretinal adhesions surrounding a FTMH for successful closure.

Abstract
PURPOSE There are no defined diagnostic criteria and severity classification for Fuchs endothelial corneal dystrophy (FECD), which are required for objective standardized assessments. Therefore, we performed a systematic literature review of the current diagnosis and severity classification of FECD. METHODS We searched the Ovid MEDLINE and Web of Science databases for studies published until January 13, 2021. We excluded review articles, conference abstracts, editorials, case reports with <5 patients, and letters. RESULTS Among 468 articles identified, we excluded 173 and 165 articles in the first and second screenings, respectively. Among the 130 included articles, 61 (47%) and 99 (76%) mentioned the diagnostic criteria for FECD and described its severity classification, respectively. Regarding diagnosis, slitlamp microscope alone was the most frequently used device in 31 (51%) of 61 articles. Regarding diagnostic findings, corneal guttae alone was the most common parameter [adopted in 23 articles (38%)]. Regarding severity classification, slitlamp microscopes were used in 88 articles (89%). The original or modified Krachmer grading scale was used in 77 articles (78%), followed by Adami's classification in six (6%). Specular microscopes or Scheimpflug tomography were used in four articles (4%) and anterior segment optical coherence tomography in one (1%). CONCLUSIONS FECD is globally diagnosed by the corneal guttae using slitlamp examination, and its severity is predominantly determined by the original or modified Krachmer grading scale. Objective severity grading using Scheimpflug or anterior segment optical coherence tomography can be applied in the future innovative therapies such as cell injection therapy or novel small molecules.

Abstract
Purpose Myopic choroidal neovascularization (CNV) and myopic traction maculopathy are major complications of pathologic myopia, and myopic foveoschisis (MF) is one of several symptoms that can be included under the general term "myopic traction maculopathy"; however, only a few cases will have MF around the myopic CNV. We report three cases with MF around myopic CNV that followed different clinical courses observed using swept-source optical coherence tomography. Observations Case 1 was a 69-year-old woman with an axial length of 29.71 mm, myopic CNV, and MF in the left eye. One month after intravitreal injection of ranibizumab (IVR), a macular retinal detachment (RD) expanded. Vitrectomy and gas tamponade were performed during month 2; the macular RD and MF resolved gradually thereafter. Case 2 was a 54-year-old man with an axial length of 30.59 mm, myopic CNV, and MF in the right eye; after IVR, a macular RD developed and gradually expanded until month 4; the RD and MF resolved spontaneously and resolved during month 8. Case 3 was a 66-year-old woman with an axial length of 28.63 mm, myopic CNV, and MF in the left eye. A macular RD expanded 1 month after a previous vitrectomy for MF; after intravitreal injection of aflibercept, the macular RD and MF resolved gradually in month 12. In all cases, the CNV was accompanied by subretinal fluid, and two of the three cases had outer lamellar holes. Conclusion and Importance The MF around the myopic CNV may lead to exacerbated MF and RD during follow-up, and the subretinal fluid caused by the CNV might facilitate MF progression. Since this condition is rare, further investigation of this entity is needed to determine appropriate management.

Abstract
Changes in cell fluidity have been observed in various cellular tissues and are strongly linked to biological phenomena such as self-organization. Recent studies suggested variety of mechanisms and factors, which are still being investigated. This study aimed to investigate changes in cell fluidity in multi-layered cell sheets, by exploring the collective arrest of cell motion and its release in cultures of corneal epithelial cells. We constructed mathematical models to simulate the behaviors of individual cells, including cell differentiation and time-dependent changes in cell-cell connections, which are defined by stochastic or kinetic rules. Changes in cell fluidity and cell sheet structures were expressed by simulating autonomous cell behaviors and interactions in tissues using an agent-based model. A single-cell level spatiotemporal analysis of cell state transition between migratable and non-migratable states revealed that the release from collective arrest of cell motion was initially triggered by a decreased ability to form cell-cell connections in the suprabasal layers, and was propagated by chain migration. Notably, the disruption of cell-cell connections and stratification occurred in the region of migratable state cells. Hence, a modeling approach that considers time-dependent changes in cell properties and behavior, and spatiotemporal analysis at the single-cell level can effectively delineate emergent phenomena arising from the complex interplay of cells.

Abstract
Purpose We present a case of traumatic commotio retinae (CR), in which blood flow was evaluated using optical coherence tomography angiography (OCTA). Observations An 18-year-old Japanese man presented with traumatic retinal detachment and CR in his left eye, which had been hit by a handball. Fundus examination revealed peripheral retinal tear extending from the 1 to 3 o'clock position with retinal detachment, and CR near the area of tear. Fluorescein angiography (FA) confirmed an ischemic area near the retinal tear area at the CR. The patient underwent successful scleral buckling and cryopexy. Sequential OCTA imaging was performed and we were able to determine perfusion in the CR area, with maintained blood flow. Conclusions and importance In blunt eye trauma, peripheral commotio retinae can be assessed non-invasively over time using OCTA. OCTA is a useful method for evaluating peripheral retinal whitened areas.

Abstract
Purpose To evaluate the relationship between full-thickness macular hole (FTMH) onset and perifoveal posterior vitreous detachment using OCT data. Design Retrospective study. Participants A total of 742 patients with FTMH or impending macular hole (MH) in ≥ 1 eye, as determined by ophthalmoscopy and OCT. Methods Macular holes were staged using OCT results. Patients with the posterior vitreous membrane clearly detected in the OCT images and vitreoretinal adhesion size ≤ 1500 μm-eyes with MH stages 1-3-were included in the study. The contralateral eyes were also included in the analyses if they showed the focal type of vitreomacular adhesion (VMA) (i.e., vitreoretinal adhesion ≤ 1500 μm). The distance between the posterior vitreous membrane and the surface of the retina was defined as the posterior vitreous separation height (PVSH). Using the OCT images, PVSHs of each eye in 4 directions (nasal, temporal, superior, and inferior) at 1 mm from the center of the MH or fovea were calculated. Main Outcome Measures The main outcome measures were PVSHs according to the MH stage and VMA, the relationship of the foveal inner tear with PVSH, and the likelihood of a foveal inner tear based on the direction. Results The PVSH trends in each of the 4 directions were as follows: VMA < MH stage 1 = MH stage 2 < MH stage 3. Initial MH stage 2 (onset of FTMH) was defined as the presence of a gap in only 1 of the 4 directions from the center of the MH. With increased PVSH, the likelihood of a gap increased (P = 0.002), and a temporal gap was more likely to occur than a nasal gap (P = 0.002). Conclusions At FTMH onset, a foveal inner tear likely appears on the temporal side or the side showing a high PVSH value.

Abstract
Purpose To utilize volumetric analysis to quantify volumetric changes in choroidal vessels and stroma after photodynamic therapy (PDT) and focal laser photocoagulation (PC) for central serous chorioretinopathy (CSCR). Methods This retrospective, comparative study included 58 eyes (58 patients) with CSCR (PC, 33 eyes; PDT, 25 eyes) followed up with swept-source optical coherence tomography at 3 months after treatment. Three-dimensional (3D) choroidal vessel and stromal volumes in each area of the central 1.5-mm-diameter circle, the torus-shaped area with 6-mm-diameter circle excluding the area of the central 1.5-mm-diameter circle, and the treated area of the Early Treatment Diabetic Retinopathy Study (ETDRS) grid centered at the fovea were analyzed using a deep learning-based method. Changes in volume at baseline and 1 and 3 months after treatment were compared. Results The mean patient age was 49.3 ± 10.5 years. In the central 1.5-mm-diameter circle, the mean vessel and stromal volume rates significantly decreased after the treatment in both the PDT and PC groups (P = 0.00029 and P = 0.0014, respectively), and significant differences between the PDT and PC groups of continuous variables within times were observed in both volumes (P = 0.024 and P = 0.037, respectively). In the torus-shaped area and treated area, the PDT and PC groups both showed similar decreases in vessel and stromal volume over time. Conclusions In the 3D optical coherence tomography volumetric analysis, both PDT and focal PC reduced choroid vessel volume in eyes with CSCR. Translational Relevance This new finding is useful in elucidating the pathogenesis and healing mechanisms of CSCR.

Abstract
OBJECTIVES To evaluate the optical quality of different toric contact lens (CL) designs and compare their on-eye visual correction performance. METHODS Twenty soft CL wearers aged 20 to 39 years were enrolled. Two daily disposable silicone-hydrogel toric CLs were tested: the "Eyelid Stabilized Design" (ESD-CL) and prism-ballast design (PB-CL); a spherical daily disposable silicone hydrogel CL (spherical CL) was used as a control. On-eye performance was compared for corrected distance visual acuity (CDVA), astigmatism, and ocular higher-order aberrations (HOAs); astigmatism and ocular HOAs were measured with a wavefront sensor. The subjective quality of vision, rated for "blurred vision" and "double vision," lens rotation, and fitting were also compared. RESULTS The ESD-CLs, PB-CL, and no-CL provided better CDVA than spherical CL ( P <0.05). Compared with spherical CL and no CL, PB-CL and ESD-CLs caused significantly lesser astigmatism ( P <0.05). Coma was significantly lesser with ESD-CLs than that with PB-CL ( P <0.05); total HOAs did not differ among the four conditions. The subjective ratings for blurred and double vision were significantly lower with ESD-CLs than those with spherical CL ( P <0.05). CONCLUSIONS Toric CLs provide a better CDVA than spherical CLs. However, differences in coma and subjective symptoms may occur because of the design of toric CLs.

Abstract
This case report discusses the case of a 76-year-old woman with choroidal metastasis from breast cancer who was treated with intensity-modulated radiation therapy (IMRT). Choroidal metastasis is a common ocular tumor, and the occurrence of this condition has increased due to improved diagnostic tools and longer survival of metastatic patients. IMRT is an innovative radiation therapy technique that reduces complications and improves the curative effect by concentrating radiation on the tumor while minimizing exposure to surrounding tissues. In this case, the patient had a history of breast cancer and was undergoing chemotherapy when she presented with vision loss and blurred vision. Imaging tests confirmed choroidal metastasis, and IMRT was performed under the guidance of a radiation oncologist. After treatment, the choroidal lesion dramatically reduced in size, and the patient's vision improved. The text concludes that radiation therapy, including IMRT, is becoming more common as a treatment for ocular metastasis to improve vision and preserve the eye. When choosing radiation therapy, it is essential to consider the size of the tumor and the impact on surrounding tissues. IMRT is an effective treatment that enables precise and concentrated irradiation of the tumor tissue while minimizing exposure to normal tissues.

Abstract
OBJECTIVE To evaluate the usefulness of metagenomic analysis in the search for causative organisms of bacterial endophthalmitis. METHODS AND ANALYSIS Twenty-one consecutive treatment-naïve patients (13 men and 8 women; mean age, 60.8±19.8 years) with suspected endophthalmitis were recruited. Vitrectomy was performed to diagnose and treat endophthalmitis. Bacterial culture and metagenomic analysis of the vitreous body were performed. Extracted DNA was analysed using 16S rRNA sequences, and libraries were sequenced on an Illumina MiSeq sequencer. To compare the bacterial composition in each case, α and β diversities were determined. RESULTS Patients were categorised into three groups: endophthalmitis cases with matching predominant organisms according to metagenomic analysis and bacterial culture, those with negative results for bacterial culture and those with negative results in both cases. In 7 of 15 culture-negative cases, results from metagenomic analysis could detect pathogens. The diversity of bacterial populations was significantly lower in the group with positive results for predominant bacteria according to culture and metagenomic analysis. All patients with uveitis were included in the group for which the causative pathogen could not be determined by culture or metagenomic analysis. The structures of bacterial populations significantly differed between the positive and negative groups by culture and metagenomic analysis. CONCLUSIONS Metagenomic analysis could be useful for prompt detection of causative pathogens, for precise diagnosis of infection, and as a marker of inflammation processes such as uveitis.

Abstract
OBJECTIVE This study aimed to examine the differences in the fungal microbiome between patients with conjunctival mucosa-associated lymphoid tissue (MALT) and healthy controls using metagenomic analysis. METHODS AND ANALYSIS This case-control study was conducted at Osaka University Hospital in Osaka, Japan, from April 2015 to March 2022. Twenty-five consecutive patients with conjunctival MALT lymphoma and 25 healthy volunteers were included. Metagenomic analysis using Internal Transcribed Spacer (ITS)1 deep sequencing and hierarchical clustering was performed to investigate differences in the fungal microbiome. To assess tear environmental change, we measured tear mucin concentrations using ELISA. RESULTS Detailed analyses showed fungal dysbiosis and changes in β-diversity within the conjunctiva of patients with conjunctival MALT lymphoma. Hierarchical clustering revealed that the participants could be divided into three clusters according to the Malassezia abundance: cluster I (Malassezia abundance above 70%), cluster II (Malassezia abundance 25%-70%) and cluster II (Malassezia abundance below 25%). Most patients were included in cluster I, whereas most of healthy controls were included in cluster III. The differences were significant. Tear mucin concentrations were significantly lower in patients with MALT compared with healthy controls. CONCLUSION The metagenomic analysis using ITS1 deep sequencing was useful for identifying the differences in commensal fungi between patients with MALT lymphoma and healthy individuals. The increased prevalence of the Malassezia genus and the decreased levels of tear mucin can lead to an allergic response of the conjunctiva, resulting in the pathogenesis associated with conjunctival MALT lymphoma. Therefore, it may be beneficial to initiate treatment when a high abundance Malassezia is detected.

Abstract
Dry eye syndrome (DES) is a chronic ocular disease that induces epithelial damage to the cornea by decreasing tear production and quality. Adequate treatment options have not been established for severe DES such as Sjogren's syndrome due to complicated pathological conditions. To solve this problem, we focused on the conditioned medium of human adipose-derived mesenchymal stem cells (hAdMSC-CM), which have multiple therapeutic properties. Here, we showed that hAdMSC-CM suppressed Benzalkonium Chloride (BAC)-induced cytotoxicity and inflammation in human corneal epithelial cells (hCECs). In addition, hAdMSC-CM increased the expression level and regulated the localisation of barrier function-related components, and improved the BAC-induced barrier dysfunction in hCECs. RNA-seq analysis and pharmacological inhibition experiments revealed that the effects of hAdMSC-CM were associated with the TGFβ and JAK-STAT signalling pathways. Moreover, in DES model rats with exorbital and intraorbital lacrimal gland excision, ocular instillation of hAdMSC-CM suppressed corneal epithelial damage by improving barrier dysfunction of the cornea. Thus, we demonstrated that hAdMSC-CM has multiple therapeutic properties associated with TGFβ and JAK-STAT signalling pathways, and ocular instillation of hAdMSC-CM may serve as an innovative therapeutic agent for DES by improving corneal barrier function.

Abstract
The conjunctival epithelium consists of conjunctival epithelial cells and goblet cells derived from conjunctival epithelial stem/progenitor cells. However, the source of these cells is not well known because no specific markers for conjunctival epithelial stem/progenitor cells have been discovered. Therefore, to identify conjunctival epithelial stem/progenitor cell markers, we performed single-cell RNA sequencing of a conjunctival epithelial cell population derived from human-induced pluripotent stem cells (hiPSCs). The following conjunctival epithelial markers were identified: BST2, SLC2A3, AGR2, TMEM54, OLR1, and TRIM29. Notably, BST2 was strongly positive in the basal conjunctival epithelium, which is thought to be rich in stem/progenitor cells. Moreover, BST2 was able to sort conjunctival epithelial stem/progenitor cells from hiPSC-derived ocular surface epithelial cell populations. BST2-positive cells were highly proliferative and capable of successfully generating conjunctival epithelial sheets containing goblet cells. In conclusion, BST2 has been identified as a specific marker of conjunctival epithelial stem/progenitor cells.

Abstract
Childhood glaucoma is one of the major causes of blindness in children, however, its diagnosis is of great challenge. The study aimed to demonstrate and evaluate the performance of a deep-learning (DL) model for detecting childhood glaucoma based on periocular photographs. Primary gaze photographs of children diagnosed with glaucoma with appearance features (corneal opacity, corneal enlargement, and/or globe enlargement) were retrospectively collected from the database of a single referral center. DL framework with the RepVGG architecture was used to automatically recognize childhood glaucoma from photographs. The average receiver operating characteristic curve (AUC) of fivefold cross-validation was 0.91. When the fivefold result was assembled, the DL model achieved an AUC of 0.95 with a sensitivity of 0.85 and specificity of 0.94. The DL model showed comparable accuracy to the pediatric ophthalmologists and glaucoma specialists in diagnosing childhood glaucoma (0.90 vs 0.81, p = 0.22, chi-square test), outperforming the average of human examiners in the detection rate of childhood glaucoma in cases without corneal opacity (72% vs. 34%, p = 0.038, chi-square test), with a bilateral corneal enlargement (100% vs. 67%, p = 0.03), and without skin lesions (87% vs. 64%, p = 0.02). Hence, this DL model is a promising tool for diagnosing missed childhood glaucoma cases.

Abstract
ABSTRACT We retrospectively examined corneal refractive power in three patients who had been followed up for more than 20 years after radial keratotomy (RK) with microperforations (MPs). All patients underwent RK in both eyes and were referred to our clinic because of postoperative decreased vision. MP was observed in five of the six eyes at the initial visit. The corneal refractive power of the anterior and posterior surfaces of the 6-mm-diameter cornea was examined using Fourier analysis based on corneal shape analysis using anterior segment optical coherence tomography. The spherical components decreased in all three cases. The asymmetry and higher-order irregularity components and fluctuations in corneal refractive power were markedly greater in the two cases with MP in both eyes. Fluctuations in corneal refractive power were observed at more than 20 years after RK with MP. Therefore, careful observation is necessary, even after a long-term postoperative follow-up period.

Abstract
Effective drug therapy for vitreoretinal disease is a major challenge in the field of ophthalmology; various protective systems, including anatomical and physiological barriers, complicate drug delivery to precise targets. However, as the eye is a closed cavity, it is an ideal target for local administration. Various types of drug delivery systems have been investigated that take advantage of this aspect of the eye, enhancing ocular permeability and optimizing local drug concentrations. Many drugs, mainly anti-VEGF drugs, have been evaluated in clinical trials and have provided clinical benefit to many patients. In the near future, innovative drug delivery systems will be developed to avoid frequent intravitreal administration of drugs and maintain effective drug concentrations for a long period of time. Here, we review the published literature on various drugs and administration routes and current clinical applications. Recent advances in drug delivery systems are discussed along with future prospects.

Abstract
BACKGROUND Iris mammillation is a rare disease characterized by the distribution of multiple nodules on the iris surface. The course of uveitic glaucoma with iris mammillation has never been reported. CASE PRESENTATION A 56-year-old woman, who presented with unilateral decreased vision, visited our hospital for treatment of uveitic glaucoma in the right eye. Multiple nodules were scattered over the iris surface in that eye. This case was diagnosed as iris mammillation on clinical findings. After excluding malignant tumors such as melanoma, trabeculectomy was performed. The resected iris had no pathologically malignant findings. The iris nodules evolved to a sand-like appearance, and the intraocular pressure remained stable without recurrent inflammation 7 years after trabeculectomy. CONCLUSIONS In a case of unilateral uveitic glaucoma with iris mammillation, filtration surgery was performed after excluding the presence of a malignancy, and the long-term postoperative course has been stable.

Abstract
OBJECTIVES To assess agreement between measurements of ocular wavefront aberrations obtained using the Pentacam AXL Wave (Oculus Optikgeräte GmbH) (Aberrometer A) and KR-1W (Topcon Corp) (Aberrometer B), both of which are based on the Hartmann-Shack principle. METHODS In this prospective case-control study, ocular wavefront aberrations measurements were obtained using both aberrometers in patients with keratoconus (KC) and control participants. Ocular wavefront aberrations were measured through the natural pupil without dilation using both devices in a dark room. For both aberrometers, accommodation was inhibited by automatically adding fogging. The individual Zernike coefficients from the second to fourth order were compared between the two aberrometers for a 4-mm pupil diameter. RESULTS Twenty-six KC and 29 control eyes were assessed. Statistically significant correlations ( P <0.05) were observed for all Zernike coefficients, except for Z 4-2 in the control group. Bland-Altman analysis indicated good agreement between aberrometers and no statistically significant differences in the control group. However, in the KC group, patterns of proportional error were observed in vertical coma Z 3-1 (r=0.338, P =0.008), trefoil Z 4-4 (r=0.701, P =0.003), secondary astigmatism Z 4-2 (r=0.348, P =0.025), and spherical aberrations Z 40 (r=0.407, P =0.012). CONCLUSIONS The Zernike coefficient values measured by the two aberrometers were well correlated in the control and KC groups. However, in eyes with KC, Aberrometer B tended to present greater values in several Zernike coefficients than Aberrometer A, suggesting that wavefront measurements obtained using the two aberrometers are not interchangeable in patients with KC.

Abstract
PURPOSE To determine the influence of stimulating electrode conditions on the amplitudes and latencies of electrically evoked potentials (EEPs) and the resistance at the electrode-tissue interface in the suprachoroidal transretinal stimulation (STS) system. STUDY DESIGN Experimental study. METHODS A scleral pocket (3 × 5 mm) was created just over the visual streak in anesthetized pigmented rabbits (weight, 1.9-2.7 kg), and STS stimulating electrodes were implanted into the pocket. Measurements were obtained with stimulating electrodes of different lengths (0.3 or 0.5 mm) and different surface characteristics (smooth or porous). EEPs elicited with a fixed current under each set of electrode conditions were recorded; three measurement sessions were performed for each rabbit. The resistance at each electrode-tissue interface was measured. RESULTS The latencies and amplitudes of the EEPs did not differ significantly with changes in the height and surface characteristics of the stimulating electrodes, but the resistances at the electrode-tissue interface differed significantly (P = 0.001; the resistance values for the 0.3-mm-long electrode with a porous surface was 5.24 ± 0.67 kΩ and with the 0.3- and 0.5-mm-long electrodes with smooth surfaces were 7.63 ± 0.12 kΩ and 6.77 ± 0.20 kΩ). CONCLUSION Being shorter did not affect the EEPs of the stimulating electrodes with a porous surface while decreasing the resistance at the electrode-tissue interface.

Abstract
BACKGROUND/PURPOSE To report a safe and simple surgical technique for the removal of a dislocated capsular tension ring (CTR)-intraocular lens (IOL)-capsular bag (CB) complex. METHODS We present an extraocular surgical removal technique for a dislocated CTR-IOL-CB complex. Although the entire complex is typically removed with a large incision, this approach applies a CTR injector and anterior capsule forceps in a less invasive manner. RESULTS After vitrectomy, the complex was moved to the anterior chamber, where the tip of the CTR was separated from the IOL-CB using anterior capsule forceps and hooked onto the tip of the CTR injector. Subsequently, the CTR, as well as part of the CB, was gradually separated from the IOL-CB and stored in the CTR injector. This was completed while also supporting the IOL-CB complex using the forceps. Once the whole CTR and the part of CB were removed from the anterior chamber, the residual IOL and CB were then removed. CONCLUSION Our methodology, using the CTR injector and anterior capsule forceps, enables the procedure to be completed with only a small corneal incision, thereby allowing for the safe and simple removal of a CTR-IOL-CB complex.

Abstract
OBJECTIVE OR PURPOSE To confirm the efficacy and safety of Good Manufacturing Practice (GMP)-compliant autologous cultivated limbal epithelial cell sheets in government-controlled clinical trials that adhered to Good Clinical Practice stipulations for patients with unilateral limbal stem cell deficiency (LSCD). DESIGN A prospective, multi-center, open-label, uncontrolled, single-arm clinical trial. SUBJECTS, PARTICIPANTS OR CONTROLS Ten consecutive eyes of 10 patients with unilateral LSCD were followed for two years after surgery. Preoperative LSCD stage was IIB in four eyes and III in six eyes. METHODS A limbal tissue biopsy was obtained from the healthy eye, after which limbal stem cells were dissociated and cultivated on temperature-responsive culture surfaces. All cell sheets were fabricated in a GMP-grade facility under established standard operating procedures. Cell sheets were evaluated using defined shipment criteria before transplantation, and only those that met the criteria were used. The cell sheet was transplanted onto each of the patients' diseased eye after removing the conjunctival scar tissue that covered the corneal surface. The severity of LSCD was determined according to a staging method agreed upon by global consensus, with eyes evaluated as being in stages IA-C representing successful corneal epithelial reconstruction. LSCD diagnosis and staging were determined by the trial's Eligibility Judgment Committee and Effect Assessment Committee using slit-lamp photographs including fluorescein staining. Both committees comprised two or three third-party cornea specialists, who were provided with information anonymously and randomly. MAIN OUTCOME MEASURE Corneal epithelial reconstruction rate was the primary endpoint. RESULTS Corneal epithelial reconstruction was successful in six of 10 eyes (60%) one year postoperatively and was significantly higher than the 15% clinically significant efficacy rate achieved by allogeneic limbal transplantation. The reconstruction rate was 70% of eyes two years postoperatively. Additionally, improvements in visual acuity were noted in 50% and 60% of eyes at one and two years, respectively. No clinically significant transplantation-related adverse events were observed. CONCLUSION The efficacy and safety of cultivated limbal epithelial cell sheet transplantation were thus confirmed, and the cell sheet, named Nepic, is now approved as a Cellular and Tissue-Based Product in Japan.

Abstract
PURPOSE To examine the outcomes of pars plana vitrectomy (PPV) with lamellar hole-associated epiretinal proliferation (LHEP) embedding and conventional internal limiting membrane (ILM) peeling for lamellar macular holes (LMHs) with LHEP. DESIGN Retrospective observational study. SUBJECTS Forty eyes of 39 consecutive patients with LMHs and LHEP who underwent 3-port PPV with a minimum follow-up of 3 months. METHODS We compared the results of eyes that underwent PPV with LHEP embedding and ILM peeling (group E) with those of eyes that underwent PPV with ILM peeling only (group I) from September 2010 to September 2021. We confirmed whether the LHEP was embedded using postoperative OCT in all the cases. MAIN OUTCOME MEASURES Postoperative best-corrected visual acuity (BCVA) and the development of macular holes (MHs) were assessed. RESULTS The mean patient age was 73.3 years. The mean follow-up duration was 23.1 months. There were 23 and 17 eyes in groups E and I, respectively. Preoperative BCVA (P = 0.774) and central retinal thickness (CRT) (P = 0.800) did not differ significantly between the 2 groups. The final BCVA in group E was better than that in group I (P = 0.059). The final CRT in group E was thicker than that in group I (P < 0.001). Postoperatively, a significant improvement in BCVA was observed in group E at 3 months (P = 0.001) and at the final visit (P < 0.001). None of the eyes in group E developed postoperative MHs, whereas 5 eyes in group I developed postoperative MHs. CONCLUSIONS Pars plana vitrectomy using the LHEP embedding technique improved visual acuity significantly and yielded better anatomic outcomes than those with PPV using conventional ILM peeling; MH formation did not occur. Embedding LHEP is more effective than conventional surgical procedures for LMHs.

Abstract
Castleman disease (CD) is a lymphoproliferative disorder and rarely affects ocular tissue. This study aimed to report a case of hypertensive choroidopathy in a patient with Castleman's disease associated with malignant hypertension. A 39-year-old man visited his local physician with fever, systemic edema, and multiple lymphadenopathies. An inguinal lymph node biopsy indicated CD. One month after the biopsy, the patient noted a blurring of vision. At the time of the initial examination at our hospital, his best-corrected visual acuity (BCVA) was 20/20 in both eyes but there were bilateral multiple Elschnig spots and sprinter hemorrhage at the fundus. Swept-source optical coherence tomography showed intra-retinal fluid, and serous retinal detachment (SRD). Fluorescein angiography revealed multiple punctate hyper fluorescences and indocyanine green angiography showed choroidopathy with increased vascular permeability. A general examination revealed symptoms of cardiac failure and multiple lymphadenopathies. Malignant hypertension with acute glomerulonephritis was diagnosed after a renal biopsy. After antihypertensive treatment, his blood pressure (BP) improved, and the SRD and choroidopathy promptly resolved. Presently, the patient is being followed up without complications. We report a case of hypertensive choroidopathy in a patient with CD associated with malignant hypertension. As a severe elevation in BP can damage choroidal vasculature and lead to vision loss, careful observation and active treatment are necessary.

Abstract
OBJECTIVE Nicotinamide adenine dinucleotide regulates various biological processes. Nicotinamide mononucleotide (NMN) increases its intracellular levels and counteracts age-associated changes in animal models. We investigated the safety and efficacy of oral nicotinamide mononucleotide supplementation in older patients with diabetes and impaired physical performance. METHOD We carried out a 24-week placebo-controlled, double-blinded study of male patients with diabetes aged ≥65 years with reduced grip strength (<26 kg) or walking speed (<1.0 m/s). The primary end-points were to determine the safety of NMN oral administration (250 mg/day), and changes in grip strength and walking speed. The secondary end-points were to determine the changes in various exploratory indicators. RESULTS We studied 14 participants aged 81.1 ± 6.4 years. NMN was tolerable without any severe adverse events. The changes in grip strength and walking speed showed no difference between the two groups: 1.25 kg (95% confidence interval -2.31 to 4.81) and 0.033 m/s (-0.021 to 0.087) in the NMN group, and -0.44 kg (-4.15 to 3.26) and 0.014 m/s (-0.16 to -0.13) in the placebo group, respectively. There were no significant differences in any exploratory indicators between the two groups. However, improved prevalence of frailty in the NMN group (P = 0.066) and different changes in central retinal thickness between the two groups (P = 0.051) was observed. CONCLUSION In older male patients with diabetes and impaired physical performance, NMN supplementation for 24 weeks was safe, but did not improve grip strength and walking speed.

Abstract
Extensive macular atrophy with pseudodrusen (EMAP) is a relatively newly proposed clinical entity that was first reported in 2009. Although no definitive diagnostic criteria have been defined, characteristic findings can distinguish it from other diseases, especially dry age-related macular dystrophy (AMD). Herein, we present the case of a patient with EMAP who underwent a comprehensive ophthalmic examination and whole-exome sequencing (WES). A 72-year-old Japanese man complained of progressive visual impairment in his right eye and nyctalopia. Ophthalmic examination revealed that the best-corrected visual acuity (BCVA) in decimal units was 0.08 on the right and 0.8 on the left. Fundoscopy and fundus autofluorescence (FAF) revealed well-demarcated symmetrical macular atrophy, with a vertical axis larger than the horizontal axis, which reached the vascular arcade inferiorly and exceeded it superiorly. Pseudodrusen were widespread throughout the retina in both eyes. Paving-stone degeneration was not observed in the extreme periphery of either eye. Seven months later, his left BCVA decreased to 0.3 without major changes on multimodal imaging. Based on the above findings, we diagnosed EMAP. Wide-field optical coherence tomography angiography (OCTA) showed no significant changes in the retinal vessels, but the density of choroidal vessels was reduced in the degenerated areas. We thought that this finding suggests that EMAP originates between the deep retina and choroid. WES did not reveal any candidate mutations in known pathogenic genes. To the best of our knowledge, this is the first report of a Japanese patient with EMAP, and no data for analysis of wide-field OCTA or equatorial OCT images of EMAP cases have been found in previous reports. EMAP is not well recognized in Asia and may be incorrectly diagnosed as dry-type AMD. EMAP should be included in the differential diagnosis of dry AMD, and this may lead to more Asians being diagnosed with EMAP in the future.

Abstract
PURPOSE The purpose of this article was to describe the successful diagnosis and management of clinically atypical, unilateral, gelatinous drop-like corneal dystrophy (GDLD) in a pediatric patient. METHODS This study was a case report. RESULTS A 7-year-old Japanese girl was referred to our clinic with right corneal opacity for over 3 years. Slitlamp examination revealed a white, protruding, paracentral corneal opacity with an irregular surface and tiny stromal lattice figures with subepithelial opacities. No trichiasis or epiblepharon was observed, and the patient's right corrected distance visual acuity (CDVA) was 18/20. The contralateral cornea was intact but demonstrated fluorescein uptake. After 8 months, the right CDVA worsened from 18/20 to 6/20, and corneal epithelial scraping was performed. Histopathological analysis revealed amyloid nodules in the subepithelial layer and in the anterior corneal stroma stained with Congo red, which reoccurred 2 months after the procedure, and corneal dystrophy was suspected. Isolation and sequencing of the genomic DNA revealed a homozygous p.Gln118Ter. mutation in TACSTD2 in the patient and heterozygous p.Gln118Ter. mutations in both parents. GDLD was diagnosed; bilateral use of therapeutic soft contact lenses was prescribed after the first corneal scraping. No additional surgical intervention was required for the right eye for 4.5 years. CDVA of the contralateral left eye has been successfully maintained at 30/20 over this period, without emergence of nodular lesions or corneal opacities. CONCLUSIONS We encountered a patient with early, atypical GDLD, who was definitively diagnosed using genomic DNA sequencing. GDLD should be a part of the differential diagnosis in patients presenting with unilateral, recurrent amyloid deposition.

Abstract
Purpose To present a novel microscope-integrated optical coherence tomography (iOCT)-guided surgical technique wherein Descemet's membrane detachment (DMD), occurring during vitrectomy, was treated intraoperatively in a patient who had previously undergone Descemet's stripping automated endothelial keratoplasty (DSAEK). Observations The surgical technique was performed on a 75-year-old man with a history of DSAEK to intraoperatively treat DMD, which occurred during vitrectomy in the left eye. A fine needle mounted on a syringe was inserted into the supra-Descemet's space under iOCT guidance. The location of the needle was easily identified by its high reflection. The interface fluid was safely aspirated under excellent visualization of the needle tip and the interface. Successful aspiration of the interface fluid was confirmed via iOCT imaging at the end of the surgery. The graft has remained well attached to the cornea throughout the one-year postoperative follow-up. Conclusion and importance iOCT-guided surgical interventions provide a safe and accurate approach for treating intraoperative complications in eyes with a history of DSAEK.

Abstract
Purpose To report findings on the tilt angle of optic nerve heads (ONHs) that developed intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage (IHAPSH) using swept-source optical coherence tomography (SS-OCT). Observations Five consecutive patients who presented with IHAPSH were reviewed retrospectively. We reviewed five consecutive eyes from the five patients, analyzed the optic tilt angle obtained from SS-OCT B-scans, and compared the results and other clinical characteristics. All patients had larger optic disc tilt angles in the eyes with IHAPSH than in the contralateral, unaffected eye. The mean ratio of the tilt angle in the eyes with IHAPSH to that in the contralateral eye was 1.37 (95% confidence interval 1.15–1.58). Conclusions and Importance The ONH of IHAPSH was evaluated quantitatively with SS-OCT for the first time in this study. Larger angle tilted discs in IHAPSH-affected eyes are anatomically and histologically more vulnerable and may explain why IHAPSH develops monocularly.

Abstract
Purpose Proton beam radiation therapy (PBRT) is a treatment option for advanced retinoblastoma (RB) resistant to chemotherapy and focal ophthalmic treatment. Here we report a case of RB with phthisis bulbi following PBRT. Observations A 16-day-old boy with a family history of RB was referred to our institution. Initial examination revealed an extensive white mass in the right eye and a small tumor near the optic disk of the left eye. The patient was diagnosed with bilateral RB and treated with chemotherapy and focal ophthalmic therapy. The right eye showed shrinkage in the treatment course. The tumor control was not achieved bilaterally, and, therefore, PBRT was performed to preserve the eyes. However, the right eye became significantly phthisical following PBRT and ultimately required enucleation. Conclusions and importance PBRT for RB may result in phthisis bulbi. Further investigations of its role and possible complications are warranted.

Abstract
<b><i>Introduction:</i></b> This study aimed to describe the quantitative features of the microvasculature in the cystic lesions of branch retinal vein occlusion (BRVO). <b><i>Methods:</i></b> A total of 43 eyes with BRVO, treated with anti-vascular endothelial growth factor therapy, were analyzed. Using wide-field swept-source optical coherence tomography angiography (OCTA), en face OCT images were obtained by depth-integrated reflectivity of the retina, and vascular density (VD), vascular length (VL), vascular lacunarity, and fractal dimension (FD) were evaluated in a 12 × 12-mm area of retinal nonperfusion. <b><i>Results:</i></b> The mean area of affected lesions was 38.7 ± 19.8 mm<sup>2</sup>, and cystic lesions were 8.5 ± 10.1 mm<sup>2</sup>. VD, VL, and FD were significantly decreased in the cystic lesions compared to other affected lesions in the same eyes (<i>p</i> = 0.0010, <i>p</i> = 0.0001, and <i>p</i> = 0.0003, respectively) and in all eyes (<i>p</i> = 0.0281, <i>p</i> = 0.0050, and <i>p</i> < 0.0001, respectively). VD in cystic lesions within the vascular arcade (25 eyes) correlated with best-corrected visual acuity on OCTA (<i>r</i> = −0.433, and <i>p</i> = 0.0492). <b><i>Conclusions:</i></b> Vascular structure in the cystic lesions was unpreserved compared to the other lesions in BRVO. These findings may help in understanding the pathophysiology of retinal edema in BRVO.
