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
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
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
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 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
When corneal epithelial stem cells residing in the corneal limbus become dysfunctional, called a limbal stem cell deficiency (LSCD), corneal transparency is decreased, causing severe vision loss. Transplantation of corneal epithelial cell sheets (CEPS) derived from stem cells, including induced pluripotent stem cells, is a promising treatment for LSCD. However, the potential effect of human leukocyte antigen (HLA) concordance on CEPS transplantation has not been addressed. Here, we show that there is no difference in the immune response to CEPS between HLA-matched and -unmatched peripheral blood mononuclear cells in mixed lymphocyte reactions. CEPS transplantation in cynomolgus monkeys revealed that the immune response to major histocompatibility-unmatched CEPS was not strong and could be controlled by local steroid administration. Furthermore, programmed death ligand 1 was identified as an immunosuppressive molecule in CEPS under inflammatory conditions in vitro. Our results indicate that corneal epithelium has low immunogenicity and allogeneic CEPS transplantation requires mild immunosuppression. There is no difference in the immune response to CEPS owing to HLA conformity in MLR The immune response to MHC-unmatched CEPS is not strong after transplantation Local steroid administration could control the immune response to MHC-unmatched CEPS PD-L1 was identified as an immunosuppressive molecule in CEPS

Abstract
We report a case in which intraocular endoscopy clarified the cause of Ahmed glaucoma valve (AGV) failure with a cloudy cornea. A 42-year-old patient with glaucoma underwent AGV implant surgery to treat secondary glaucoma due to chronic iridocyclitis in his left eye. After AGV, he developed bullous keratopathy (BK) in that eye. After Descemet stripping automated endothelial keratoplasty (DSAEK) was performed to treat BK, the intraocular pressure (IOP) increased and early failure of the DSAEK resulted again in a cloudy cornea. We could not precisely detect any cause of AGV failure with ordinary imaging instrumentation. An intraocular endoscope was used to determine that cause, and we found that the fibrous tissue occluded the tube of the AGV. The IOP decreased soon after the tissue was removed. We conclude that intraocular endoscopy was useful for diagnosing AGV failure with BK.

Abstract
Background Filamentous fungi are ubiquitous in plants, water, and soil. The predominant fungi that infect the human cornea include Fusarium and Aspergillus species. The onset of fungal endophthalmitis is indolent, and typically takes weeks to months to develop after corneal infection. We report a case of Fusarium infection complicating rheumatic keratitis that acutely progressed to endophthalmitis during intravenous tocilizumab therapy. Case presentation A 65-year-old female patient was referred to our department due to pain and decreased vision in her left eye. Slit-lamp examination showed a white focus on the upper peripheral cornea, hypopyon, anterior chamber fibrin formation, marked ciliary hyperemia, and whole corneal epithelial defects. As the corneal scraping smear was positive for filamentous fungi and Fusarium species were detected by aqueous humor polymerase chain reaction, anti-fungal therapy was started. Although the initial response to anti-fungal therapy was good, we observed corneal infiltration, worsening hypopyon, and vitreous opacity after tocilizumab infusion. Given that the infection continued to progress despite conservative therapy, we performed penetrating keratoplasty combined with vitrectomy. After removal of the white focus beneath the intraocular lens, a temporary corneal prosthesis was mounted and the dense vitreous opacity was removed. Finally, a frozen donor graft was sutured in place. The corneal infiltration, hypopyon, and vitreous opacity all disappeared after the operation. Conclusion The rapid progression of Fusarium keratitis to endophthalmitis in a patient who was receiving a regular infusion of tocilizumab demonstrates that ocular condition should be closely monitored during systemic tocilizumab administration due to increased risk of infection.

Abstract
PURPOSE To evaluate the correlation between anterior chamber parameters and central corneal thickness (CCT) or peripheral corneal thickness (PCT) in patients with Fuchs endothelial corneal dystrophy (FECD) using anterior segment optical coherence tomography. METHODS This case-control study included 20 eyes from 20 patients with FECD and 31 eyes from 31 patients with healthy corneas. CCT was measured as an indicator of FECD severity. Anterior chamber angle parameters, including trabecular-iris angle (TIA500) and angle opening distance (AOD500), were measured as an indicator of peripheral anterior chamber morphology. We also analyzed PCT and lens vault (LV). The relationships between CCT or PCT and anterior chamber parameters were also analyzed in patients with FECD. RESULTS Patients with FECD had a larger CCT (593.9 ± 54.6 μm vs. 533.0 ± 25.4 μm, P < 0.001), smaller TIA500 (21.8 ± 9.9 vs. 32.5 ± 11.2 degrees, P = 0.002), smaller AOD500 (0.21 ± 0.11 vs. 0.34 ± 0.18 mm, P = 0.002), and greater LV (0.60 ± 0.27 vs. 0.40 ± 0.29 mm, P = 0.02) than control subjects. In patients with FECD, CCT was negatively correlated with the angle parameters TIA500 (R = 0.29, P = 0.009) and AOD500 (R = 0.19, P = 0.03). There were no significant correlations between PCT and TIA500 (R = 0.008, P = 0.29) or AOD500 (R = 0.007, P = 0.29). There were also no significant correlations between CCT and LV (R = 0.02, P = 0.55). CONCLUSIONS Larger CCT was significantly associated with narrower anterior chamber angle width, but not with LV. We showed that the severity of FECD is associated with angle chamber morphology.

Abstract
PURPOSE To report on a second-generation prototype contact lens (modified lens) with enhanced optics to correct coma aberration and compare its performance with that of the prototype contact lens (conventional lens) used to optimise correction of coma aberration in keratoconus (KC). METHODS Both lenses were designed as a set of standardised soft contact lenses (SCLs) with asymmetric powers along the posterior surface. The modified lens differs from the conventional lens in that the optical zone is decentred superiorly by 0.7 mm. The on-eye performance was compared between the SCLs and no-lens wearing in terms of manifest refraction, corrected distance visual acuity (CDVA), ocular aberrations, subjective quality of vision, and on-eye lens position relative to the pupil. RESULTS Thirty-four KC eyes were included. SCLs significantly decreased coma aberration compared to no-lens wear (none, 0.68 ± 0.27 μm; conventional lens, 0.37 ± 0.28 μm; modified lens, 0.19 ± 0.15 μm; P < 0.001), with the reduction in coma aberration being significantly greater with the modified lens than with the conventional lens (P = 0.018). No significant difference in manifest refraction or CDVA was found among the three conditions. Quality of vision was significantly better with the modified lens than with no SCL wear (P < 0.05) but no differences were found between the SCLs. The on-eye optical center position relative to the pupil was closer to the pupil centre using the modified lens than the conventional lens (P < 0.001). CONCLUSION Optimisation of the location of the optical zone in a standardised asymmetric SCL improves correction of coma aberrations and on-eye optical centration.

Abstract
Purpose This study aimed to quantitatively analyze the association between follow-up duration and the severity of limbal stem cell deficiency (LSCD) or visual acuity in patients with aniridia. Methods A total of 52 eyes of 27 patients with aniridia were enrolled at Osaka University Hospital. Medical records were retrospectively reviewed to obtain information on the severity of LSCD and corrected distance visual acuity (CDVA). LSCD severity was based on a modified severity grading scale. We used an ordered logistic regression model to examine the association between follow-up duration and LSCD severity, and a linear regression model with a generalized linear mixed model for the association between follow-up duration and visual acuity. Results The mean follow-up duration was 5.2 ± 6.3 years. The mean age at the last follow-up visit was 40.5 ± 18.9 years. The mean CDVA was 1.52 ± 1.09 logMAR. At the last follow-up, 1 examined eye (1.9%) was categorized as stage 0, 7 (13.5%) as Ia, 9 (17.3%) as Ib, 5 (9.6%) as Ic, 2 (3.8%) as IIb, 12 (23.1%) as IIc, and 11 (21.2%) as III. Five eyes (9.6%) were unclassifiable. There was a significant association between follow-up duration and LSCD severity (odds ratio per +1 year, 1.41; P < 0.001). CDVA significantly decreased as follow-up duration increased. Each increase of 1 year in the follow-up duration was associated with a mean difference of +0.021 logMAR (95% confidence interval [CI] 0.01–0.03; P < 0.001). Conclusions We quantitatively demonstrate that LSCD severity and visual impairment significantly progress as follow-up duration increases.

Abstract
Background/AimsTo investigate the efficacy of therapeutic soft contact lenses (SCLs) in gelatinous drop-like corneal dystrophy (GDLD) management.MethodsThis was a retrospective, consecutive, observational case series, including 20 patients (40 eyes) with GDLD treated in Osaka University Hospital within the last 15 years. We tested the effects of therapeutic SCL on clinical features, visual acuity and surgical interventions. Examinations for clinical features and visual acuity were done on patients who had no surgical intervention for 3 years. Scoring and evaluation of changes in three main clinical GDLD features and visual acuity (logMAR units) were performed using Fisher’s exact test and Mann-Whitney U test. Surgery-free survival time was compared by Kaplan-Meier analyses in all patients.ResultsWe found a significantly lower rate of progression in GDLD nodular lesions in patients wearing SCLs compared with those who did not (p=0.0179). No suppressant effects were observed regarding opacity and neovascularisation, and no significant improvements were found in visual acuity (in logMAR values, SCL-on: mean=− 0.036, median=0; SCL-off: mean=0.149, median=+ 0.088; p=0.14). The surgery-free survival time for all 16 SCL-on eyes was 2770 ± 1918 days, significantly longer than that for 22 SCL-off eyes, 1342 ± 1323 days (Kaplan-Meier analysis, p=0.0007), suggesting that therapeutic SCL extends the period until surgical intervention and reduces their necessity in patients with GDLD.ConclusionWearing therapeutic SCLs in GDLD slows the progression of nodular lesions and decreases the need for surgical interventions.

Abstract
Purpose The aim of this study was to describe the postoperative outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) performed using our newly developed graft inserter (NS Endo-Inserter) and compare the findings with those for DSAEK performed using the Busin glide. Patients and methods In this retrospective, case-control, institutional study, we studied the clinical outcomes of DSAEK performed using the NS Endo-Inserter (NS group, n=13) or the Busin glide (Busin group, n=10) for patients with corneal endothelial dysfunction. Clinical parameters, including the distance-corrected visual acuity (DCVA), endothelial cell (EC) loss, and intraoperative/postoperative complications, were assessed over a 6-month follow-up period. Results At 6 months after surgery, the mean DCVA showed no significant difference between the two groups. EC loss at 3 and 6 months after DSAEK was 9.1%±20.7% and 18.2%±22.6%, respectively, in the NS group and 44.0%±25.5% and 46.5%±23.3%, respectively, in the Busin group; differences between groups were statistically significant at both 3 and 6 months (P=0.024 and P=0.016, respectively). Anterior chamber hemorrhage was observed in one patient in the Busin group. Rebubbling after surgery was required for one eye in the Busin group. No complications were observed in the NS group. Conclusion Our newly developed graft inserter for DSAEK may cause significantly less EC damage than the conventional pull-through technique using the Busin glide. Our inserter permits safe endothelial graft delivery without anterior chamber collapse and can result in successful graft attachment without complications at 6 months after surgery.

Abstract
This study investigated a case of spindle cell carcinoma (SpCC) in tongue pathological lesions. The patient experienced a local recurrence and distant metastasis after surgical intervention. Although standard chemotherapy was administered, a granulomatous mass continued to develop. This aggressive growth led to survival of the tumor. Secondary debulking surgery was performed to improve the patient's quality of life at the request of the patient. Using a tissue sample derived from the secondary debulking surgery, we performed an analysis of the tumor's cell surface antigens, differentiation potential, metastatic ability, and inhibition potential by anticancer reagents. In vitro analysis revealed that the cell population grown under adherent culture conditions expressed the mesenchymal stem cell (MSC) markers CD73, CD90, and CD105. The cell line established from this SpCC contained colony-forming unit fibroblasts (CFU-Fs) and exhibited multipotent differentiation into several mesenchymal lineages, including bone, cartilage, and fat. The SpCC cells also displayed vigorous mobilization. These characteristics suggested that they had the differentiation potential of mesenchymal cells, especially MSCs, rather than that of epithelial cells. The surgical specimen analyzed in this study resisted the molecular target reagent cetuximab, which is an epidermal growth factor receptor inhibitor. This clinical insight revealed that chemotherapy-resistant SpCC cells have different characteristics compared to most other cancer cells, which are sensitive to cetuximab. Our cell death assay revealed that SpCC cell death was induced by the anticancer drug imatinib, which is known to inhibit protein tyrosine kinase activity of ABL, platelet-derived growth factor receptor α (PDGFRα), and KIT. Here, we report recurrent SpCC with characteristics of MSCs and potential for treatment with imatinib.

Abstract
PURPOSE To investigate the effect of the severity of corneal guttae on quality of vision (QOV) in patients with mild Fuchs' endothelial corneal dystrophy (FECD). DESIGN Cross-sectional study. PARTICIPANTS Twenty-three eyes of 14 patients with mild FECD without corneal edema on slit-lamp examination (5 pseudophakic eyes and 18 phakic eyes with mild lens opacity; grade 1.0-2.0 nuclear opalescence, grade 1.0-2.0 nuclear color, grade 1.0 cortical cataract, and grade 1.0 posterior subcapsular cataract on the Lens Opacities Classification System, version III). METHODS The area ratio of the corneal guttae (ARCG) in the endothelial cells was measured by multifocal specular microscopy. The QOV parameters, that is, corrected distance visual acuity (CDVA), letter contrast sensitivity (LCS), and intraocular straylight, also were measured. The correlations were assessed between the ARCG and QOV parameters and between the straylight and CDVA and LCS. MAIN OUTCOME MEASURES The ARCG, logarithm of the minimum angle of resolution CDVA, LCS, and straylight. RESULTS Univariate analysis showed that the ARCG was correlated significantly with the CDVA, LCS, and straylight (R(2) = 0.41, P = 0.001; R(2) = 0.55, P = 0.001; and R(2) = 0.39, P = 0.002, respectively). Univariate analysis also showed that straylight was correlated significantly with the CDVA and LCS (R(2) = 0.47, P = 0.001 and R(2) = 0.41, P = 0.001, respectively). CONCLUSIONS Corneal guttae without edema caused the QOV to deteriorate in eyes with FECD. Patients with higher straylight had worse CDVA or LCS. Intraocular forward light scatter caused by corneal guttae may result in visual disturbances. Quantification of corneal guttae can be useful to evaluate the effect of guttae on the QOV and determine the surgical indications of endothelial keratoplasty for eyes with mild FECD.

Abstract
PURPOSE To investigate the effect of non-invasive tear stability assessment with forced eye opening on the lower tear meniscus. METHODS Twenty-three eyes of 23 patients with aqueous-deficient dry eye and 23 eyes of 23 normal subjects were enrolled. All subjects underwent imaging with a Keratograph 5M equipped with a modified tear film scanning function. Lower tear meniscus images were captured, and tear meniscus height (TMH) was measured with an integrated ruler before and after non-invasive Keratograph break-up time (NIKBUT) measurements in each subject. Subjects were instructed to keep their eyes open as long as possible during NIKBUT measurements, and the recording was discontinued at the next blink. RESULTS The TMH values of the normal and dry eye groups were 0.20±0.05 mm and 0.14±0.03 mm, respectively, at baseline. The TMH values of dry eyes were significantly smaller than those of normal eyes (p<0.001). Significant increases in TMH values were observed in both normal (0.10±0.12 mm) and dry eyes (0.04±0.09 mm) with the NIKBUT measurement (p<0.001, p=0.039). A moderate negative correlation was observed between increased TMH and baseline TMH in dry eyes (r=-0.44, p=0.03), whereas no correlation was observed in normal eyes (r=0.04, p=0.85). CONCLUSIONS Forced eye opening required for the non-invasive tear stability assessment influences the TMH measurement possibly due to reflex tear secretion, even in patients with aqueous-deficient dry eye. TMH should be assessed before tests that require forced eye opening.

Abstract
PURPOSE To investigate the short- and long-term effects of diquafosol ophthalmic solution on the optical quality of the eyes in patients with aqueous-deficient dry eye. METHODS Sixteen eyes in 16 patients with mild or moderate aqueous-deficient dry eye were treated with 3% diquafosol ophthalmic solution. Ocular higher-order aberrations (HOAs) were measured with a wavefront sensor before and at 15 min after diquafosol instillation at the baseline visit and at 4 weeks after treatment initiation. Dry eye symptoms, tear break-up time (BUT), corneal/conjunctival fluorescein staining and Schirmer's test were also evaluated before and after treatment with diquafosol. RESULTS Treatment with diquafosol ophthalmic solution significantly improved dry eye symptoms, corneal staining and BUT. Compared with mean total HOAs at baseline (0.180 ± 0.06 μm), those at 4 weeks after treatment significantly decreased (0.148 ± 0.039 μm; p = 0.035), whereas those 15 min after diquafosol instillation at the baseline visit did not change significantly (0.170 ± 0.049 μm; p = 0.279). CONCLUSIONS Although no significant change in HOAs was observed as a short-term effect of a single-drop instillation of diquafosol, long-term use of diquafosol to treat aqueous-deficient dry eye reduced HOAs as well as improved corneal epithelial damage and tear film stability.

Abstract
Chordomas are rare, low grade, malignant tumours derived from the ectopic remnants of the notochord that line the axial skeleton. They are characterised by their slow growth, long disease course and propensity for local relapse. Furthermore, up to 40% of non-cranial chordomas metastasise. We describe the first reported case of a hand metastasis arising from a conventional sacral chordoma after carbon ion radiotherapy. The common occurrence of distant metastasis with chordomas makes it important to perform a systemic examination, in part because their resection might improve patient prognosis.

Abstract
We assessed the maintenance and distribution of epithelial stem/progenitor cells after corneal reconstruction using tissue-engineered oral mucosal cell sheets in a rat model. Oral mucosal biopsy specimens were excised from green fluorescent protein (GFP) rats and enzymatically treated with Dispase II. These cells were cultured on inserts with mitomycin C-treated NIH/3T3 cells, and the resulting cell sheets were harvested. These tissue-engineered cell sheets from GFP rats were transplanted onto the eyes of a nude rat limbal stem cell deficiency model. Eight weeks after surgery, ocular surfaces were completely covered by the epithelium with GFP-positive cells. Transplanted corneas expressed p63 in the basal layers and K14 in all epithelial layers. Epithelial cells harvested from the central and peripheral areas of reconstructed corneas were isolated for a colony-forming assay, which showed that the colony-forming efficiency of the peripheral epithelial cells was significantly higher than that of the central epithelial cells 8 weeks after corneal reconstruction. Thus, in this rat model, the peripheral cornea could maintain more stem/progenitor cells than the central cornea after corneal reconstruction using oral mucosal epithelial cell sheets.

Abstract
PURPOSE To evaluate ocular forward light scattering and corneal backward light scattering in patients with dry eye. METHODS Thirty-five eyes in 35 patients with dry eye and 20 eyes of 20 healthy control subjects were enrolled. The 35 dry eyes were classified into two groups according to whether superficial punctate keratopathy in the central 6-mm corneal zone (cSPK) was present or not. Ocular forward light scattering was quantified with a straylight meter. Corneal backward light scattering from the anterior, middle, and posterior corneal parts was assessed with a corneal densitometry program using the Scheimpflug imaging system. RESULTS Both dry eye groups had significantly higher intraocular forward light scattering than the control group (both P<0.05). The dry eye group with cSPK had significantly higher values in anterior and total corneal backward light scattering than the other two groups. Moderate positive correlations were observed between the cSPK score and corneal backward light scattering from the anterior cornea (R=0.60, P<0.001) and corneal backward light scattering from the total cornea (R=0.54, P<0.001); however, no correlation was found between cSPK score and ocular forward light scattering (R=0.01, P=0.932). CONCLUSIONS Ocular forward light scattering and corneal backward light scattering from the anterior cornea were greater in dry eyes than in normal eyes. Increased corneal backward light scattering in dry eye at least partially results from cSPK overlying the optical zone.

Abstract
Aims The purpose of this study is to elucidate the clinical manifestations and the current treatment status of cytomegalovirus (CMV) endotheliitis via a large case series obtained from a national survey conducted in Japan. Methods The Japan Corneal Endotheliitis Study Group proposed diagnostic criteria for CMV endotheliitis based on a viral examination by PCR of aqueous humour, in combination with clinical manifestations. A national survey was then retrospectively conducted among 1160 members of the Japan Cornea Society. The study reviewed the patient profiles, clinical manifestations, and treatment modalities of individuals who met the diagnostic criteria for CMV endotheliitis. Results The study included 109 eyes of 106 patients. Mean patient age was 66.9±10.9 years (85 males (80.2%), 21 females (19.8%)). Patients were commonly diagnosed with anterior uveitis and ocular hypertension prior to confirmation of CMV endotheliitis. Coin-shaped lesions were observed in 70.6%, and linear keratic precipitates in 8.3% of the patients, respectively. 95% of cases were treated with anti-CMV drugs. Conclusions CMV endotheliitis is most common in middle-aged and elderly men. CMV endotheliitis should be suspected when patients present with corneal endotheliitis involving coin-shaped lesions accompanied by anterior uveitis and ocular hypertension.

Abstract
PURPOSE To quantitate the regional corneal differences in endothelial abnormalities in Fuchs' endothelial corneal dystrophy at multiple sites, including the peripheral zone. METHODS Forty-one eyes of 23 patients with Fuchs' endothelial corneal dystrophy were studied at Osaka University Hospital. The sizes of the areas of degeneration resulting from guttae were measured using a new noncontact specular microscope in the central cornea, the paracentral zone 0.6 mm from the center, and the peripheral zone 3.7 mm peripheral to the center. RESULTS The percentages of the images covered by the abnormal areas were 71% ± 36% in the center, 68% ± 35% in the paracentral zone, and 33% ± 36% in the peripheral zone. The values in the peripheral zone were significantly (P < 0.001) smaller than in the center and paracentral zones. The percentage of the abnormal area in the peripheral zone was correlated significantly (P < 0.001, R(2) = 0.452) with the disease grade in advanced cases, whereas those in the center or paracentral zones were not. Among the areas of the peripheral zone, the abnormal inferotemporal areas were significantly (P < 0.001) larger than superonasally. CONCLUSIONS In Fuchs' endothelial corneal dystrophy, the corneal endothelium is damaged more severely in the center and paracentral zones than in the peripheral zone, and peripheral measurement can objectively grade the disease. In the peripheral zones, the inferotemporal endothelium is damaged more severely. These findings might provide a new understanding of the disease mechanisms.

Abstract
The corneal endothelium is believed to be developmentally originated from the periocular mesenchyme via the neural crest. Human corneal endothelial progenitor cells (HCEPs) have been investigated because of their potential availability for the tissue regenerative medicine. However, the existence and the properties of HCEPs have not been elucidated yet. We first established a novel serum-free culture system for HCEPs. The HCEPs highly expressed p75 neurotrophin receptor, SOX9, and FOXC2, and partially retained the properties of neural crest and periocular mesenchyme. Further, we demonstrated that HCEPs had a high proliferative potency, and the differentiated HCEP sheets had corneal endothelial function by using the Ussing chamber system and transplantation to the rabbit cornea. These findings suggest that the HCEPs can be selectively expanded from the corneal endothelium using a specific culture system and will provide cell sheets for corneal regenerative medicine.

Abstract
We describe rigid gas-permeable (RGP) contact lens-assisted cataract surgery in patients with severe keratoconus. During cataract surgery in cases with severe keratoconus, the intraocular images are distorted and visual perspective is lost because of irregular corneal astigmatism. Poor visibility can lead to complications, including posterior capsule rupture and corneal endothelial cell damage. To overcome these problems, an RGP contact lens was placed on the cornea in 2 cases. The image distortion decreased markedly, and the visual perspective improved. Intraocular manipulations such as irrigation/aspiration were performed safely. Improvement in transillumination led to good visualization of the anterior and posterior capsules. No intraoperative or postoperative complications developed in either case. This technique provided excellent visualization during cataract surgery in patients with severe keratoconus.

Abstract
PURPOSE A transportation technique for cell sheets is necessary to standardize regenerative medicine. The aim of this article is to develop and evaluate a new transportation technique for cell sheets. MATERIAL AND METHODS We developed a transportation container with three basic functions: the maintenance of interior temperature, air pressure, and sterility. The interior temperature and air pressure were monitored by a recorder. Human oral mucosal epithelial cells obtained from two healthy volunteers were cultured on temperature-responsive culture dishes. The epithelial cell sheets were transported via an airplane between the Osaka University and Tohoku University using the developed cell transportation container. Histological and immunohistochemical analyses and flow cytometric analyses for cell viability and cell purity were performed for the cell sheets before and 12 h after transportation to assess the influence of transportation on the cell sheets. Sterility tests and screening for endotoxin and mycoplasma in the cell sheets were performed before and after transportation. RESULTS During transportation via an airplane, the temperature inside the container was maintained above 32°C, and the changes in air pressure remained within 10 hPa. The cell sheets were well stratified and successfully harvested before and after transportation. The expression patterns of keratin 3/76, p63, and MUC16 were equivalent before and after transportation. However, the expression of ZO-1 in the cell sheet after transportation was slightly weaker than that before transportation. The cell viability was 72.0% before transportation and 77.3% after transportation. The epithelial purity was 94.6% before transportation and 87.9% after transportation. Sterility tests and screening for endotoxin and mycoplasma were negative for all cell sheets. CONCLUSION The newly developed transportation technique for air travel is essential technology for regenerative medicine and promotes the standardization and spread of regenerative therapies.

Abstract
A new method was devised for inducing ice crystal formation in extracellular solution using silver iodide. A latent heat occurred immediately before temperature of sample reached -7 degrees C, when a column 70 mm high of 1.5M dimethyl sulfoxide (the freezing solution, FS) was aspirated into a plastic straw followed by 3 mm high of air and 10 mm high of 1% suspension of silver iodide in distilled water (1% AgI). To examine the effect of silver iodide as an inducer of ice crystal formation in extracellular solution on in vitro development of frozen-thawed rabbit morulae, the straws were filled by successive aspiration of the following fractions: 175 mul of FS containing the embryos, 7.5 mul of air, 25 mul of 1% AgI. The straws were cooled to -7 degrees C at 1 degrees C/min, and held at -7 degrees C for 10 min without initiating seeding; they were then cooled again to -30 degrees C at 1 degrees C/min and plunged into liquid nitrogen. After rapid thawing (>1000 degrees C/min), 100 of 109 (92%) embryos that were recovered developed into expanding blastocysts.

Abstract
INTRODUCTION Various approaches to laparoscopic single-site surgery (LESS) have been developed to reduce pain and other complications, promote recovery, and improve cosmetic outcomes, particularly relative to conventional open or laparoscopic surgery. Three-port procedures for LESS have been reported to be superior to single-port access, but they usually require expensive, technically sophisticated instruments. To avoid these problems, we have developed a modified procedure for performing LESS with a single port, referred to as the "Obama system." METHODS From January 2009 through December 2010, we performed laparoscopic cholecystectomy (LC) in 61 patients. Conventional LC with three ports was performed in 39 patients, LESS with a SILS Port was performed in 4 patients, and modified LESS was performed using the Obama system in 18 patients. The operative results were compared. RESULTS LC was successfully completed in all 61 patients, with no postoperative complications. The mean operating time was 102.3 min (C-reactive protein [CRP] ≤ 2) and 160.1 min (CRP > 2) in the 39 patients who underwent conventional LC, 108.3 min (CRP ≤ 2) in the 4 patients who underwent LESS with a SILS Port, and 116.5 min (CRP ≤ 2) and 186.5 min (CRP > 2) in the 18 patients who underwent LESS using the Obama system. No morbidity or mortality was associated with any technique. CONCLUSION The Obama system is easier to use and more efficient and reliable than any other technique currently available for LESS. This system is expected to greatly contribute to the further development and wider acceptance of LESS.

Abstract
PURPOSE To investigate the efficacy of intravitreal bevacizumab (IVB) for neovascular age-related macular degeneration (AMD). METHODS We conducted a retrospective study of 29 eyes of 29 patients with AMD (19 eyes) and polypoidal choroidal vasculopathy (PCV; 10 eyes), who were followed up at least 1 year after the initial IVB (1.0 mg/0.04 ml). The eyes were classified according to the lesion type and size. Best-corrected visual acuity (BCVA) and central retinal thickness were examined before and 3 months, 6 months and 12 months after the IVB. RESULTS The mean application times of IVB were 2.1 in 1 year. When classifying the eyes according to the lesion type, BCVA improved in 5 (26.3%) eyes with AMD and 1 (10.0%) eye with PCV by over 0.2 logarithmic minimum angle of resolution (logMAR) units. The BCVA decreased significantly 1 year after the IVB in eyes with PCV (p = 0.032). When classifying the eyes according to the lesion size, BCVA improved by over 0.2 logMAR units in the 4 (50.0%) eyes with a size of less than 1 disc diameter, 1 (10.0%) eye with the size of 1 to 3 disc diameters, and 1 (9.1%) eye with the size of over 4 disc diameters. The BCVA decreased significantly 1 year after the IVB in the eyes with the size of 1 to 3 disc diameters and with the size of over 4 disc diameters (p = 0.028, 0.013, respectively). The central retinal thickness did not change significantly at any time point compared to that before the IVB. CONCLUSIONS These results suggest that IVB may be efficacious in preserving visual acuity in AMD eyes and in eyes with the size of less than 1 disc diameter.
