RESUMO
PURPOSE OF REVIEW: To highlight the recent progression in surgical treatments for central retinal vein occlusion (CRVO) and central retinal artery occlusion (CRAO). RECENT FINDINGS: Anti-VEGF treatment, accepted as a primary treatment for CRVO, is unable to effectively treat all types of the diseases. Regarding CRAO, there are not any accepted therapies available. There have however been recent innovations in surgery, such as utilizing robotics-assisted tools in cannulation procedures for central retinal artery occlusion, or micro-cystotomy for refractory macular edema resulting from ischemic CRVO. SUMMARY: Refractory macular edema due to CRVO can be treated with aspiration of the fluid found inside the large cysts often seen in edema. The success rate of micro-cystotomy has been reported at 78% in eyes with refractory macular edema. Recent studies have shown that cannulation with tissue plasminogen activator (tPA) is effective for eyes with CRAO due to thrombus.Recent cannulation or micro-cystotomy procedures can be enhanced with the use of robotic tools which allow us to perform this difficult procedure more easily. Newly developed technology, and consequent developments in surgical procedures, will allow us to deal with unmet needs for retinal vessel occlusive diseases.

PURPOSE: This study aimed to compare functional and morphologic changes in the loading phase between patients with treatment-naïve macular neovascularization (MNV) due to neovascular age-related macular degeneration (nAMD) treated with either intravitreal brolucizumab (IVBr) or intravitreal faricimab (IVF) injections in a clinical setting. METHODS: We retrospectively studied 92 consecutive eyes of 90 patients with neovascular nAMD who were scheduled to receive IVBr (42 eyes of 41 patients) or IVF (50 eyes of 49 patients) injections between October 2021 and December 2022. All patients received three consecutive monthly injections of 6.0 mg/0.05 mL brolucizumab or 6.0 mg/0.05 mL faricimab. The best-corrected visual acuity (BCVA), central foveal thickness (CFT), and central choroidal thickness (CCT) at baseline and 1, 2, and 4 months after the initial treatment were measured and compared between the groups. RESULTS: Thirty-seven eyes in IVBr group and forty-seven eyes in IVF group who finished treatments in the loading phase were assessed at the follow-up examination. The BCVA, CFT, and CCT changed significantly after loading phase in both groups (P < 0.05 for both comparisons). The IVBr group had more rapid improvement of the BCVA (P = 0.037) at 1 month than the IVF group, but there was no difference at 4 months (P = 0.367). The CFT and CCT decreases tended to be greater in the IVBr group than in the IVF group throughout the follow-up period. Of the five eyes excluded from the IVBr group, one eye (2.4%) each had intraocular inflammation (IOI) and was a non-responder, and two eyes (4.8%) had retinal pigment epithelial tears after treatment. Of the three eyes excluded from the IVF group, two eyes (4.0%) did not respond to the treatment. CONCLUSIONS: Both IVBr and IVF injections were well-tolerated and improved the VA in treatment-naïve patients with MNV due to nAMD after a loading phase, although IVBr caused a trend toward faster visual improvements in the BCVA. The IVBr group also had greater reductions of the CFT and CCT than the IVF group. However, the potential for adverse events and no response to treatment with each drug are considerations.

PURPOSE: To construct a quantitative evaluation system for hand tremor during internal limiting membrane (ILM) peeling and investigate changes in hand tremor attributable to the use of the customized passive surgical support robot. METHODS: This analytical and experimental study developed a hand tremor evaluation system that synchronizes three elements: surgical microscope images, an artificial eye module with a force sensor to simulate ILM peeling, and microforceps with an inertial measurement unit. Two surgeons used this system to measure hand tremor during ILM peeling with and without the robot. RESULTS: The horizontal, vertical, and combined vertical and horizontal components of hand tremor were 8.1 ± 6.1, 1.7 ± 1.8, and 8.5 ± 6.2 mG, respectively, in the no robot group. These components decreased to 7.2 ± 6.0, 1.5 ± 1.7, and 7.5 ± 6.1 mG, respectively, in the robot group. In particular, hand tremor was significantly suppressed by 11.9% for the horizontal component using the robot (p = 0.0006). CONCLUSION: The newly constructed system helps to quantitatively evaluate hand tremor during ILM peeling. The customized passive surgical support robot enables to decrease hand tremor during ILM peeling.
RESUMO
PURPOSE: To evaluate retinal circulation in eyes with central retinal artery occlusion (CRAO). METHODS: The best-corrected visual acuity (BCVA), fluorescein angiography (FA), and laser speckle flowgraphy (LSFG) values were measured at the first visit in 42 patients with CRAO (42 eyes; mean age, 66.0±14.0 years. LSFG was performed at baseline, 1 week, and 1, 3, and 6 months; the difference between the mean blur rate vessel area and mean blur rate tissue area (MV-MT), reflecting the retinal vessel blood flow, was measured. FA measured the arteriovenous passage (AV) time. Time-course changes in the MV-MT and BCVA and the relationship between MV-MT and final BCVA were examined. RESULTS: MV-MT was significantly correlated with AV time (P<0.001). The MV-MT increased significantly after 1, 3, and 6 months (P<0.001). The VA improved significantly until 1 month (P<0.01). Multivariate analysis showed a significant correlation between the baseline BCVA (P<0.001) and MV-MT at 1 month (P=0.01) and the final BCVA. Age and MV-MT were significantly negatively correlated at 1 month (P<0.001). CONCLUSIONS: The retinal circulation improved significantly within 1 month; younger patients had better retinal circulation improvement. The baseline BCVA and retinal circulation within 1 month were correlated with the final BCVA.
RESUMO
PURPOSE: To investigate the genetic architecture of age-related macular degeneration (AMD) in a Japanese population. DESIGN: Genome-wide association study (GWAS). PARTICIPANTS: Three thousand seven hundred seventy-two patients with AMD and 16 770 control participants from the Japanese population were enrolled in the association analyses. METHODS: We conducted a meta-analysis of 2 independent GWASs that included a total of 2663 patients with AMD and 9471 control participants using the imputation reference panel for genotype imputation specified for the Japanese population (n = 3541). A replication study was performed using an independent set of 1109 patients with AMD and 7299 control participants. MAIN OUTCOME MEASURES: Associations of genetic variants with AMD. RESULTS: A meta-analysis of the 2 GWASs identified 6 loci significantly associated with AMD (P < 5.0 × 10-8). Of these loci, 4 were known to be associated with AMD (CFH, C2/FB, TNFRSF10A, and ARMS2), and 2 were novel (rs4147157 near WBP1L and rs76228488 near GATA5). The newly identified associations were confirmed in a replication study (P < 0.01). After the meta-analysis of all datasets, we observed strong associations in these loci (P = 1.88 × 10-12 and P = 1.35 × 10-9 for meta-analysis for rs4147157 and rs76228488, respectively). When we looked up the associations in the reported central serous chorioretinopathy (CSC) GWAS conducted in the Japanese population, both loci were associated significantly with CSC (P = 4.86 × 10-3 and P = 4.28 × 10-3 for rs4147157 and rs76228488, respectively). We performed a genetic colocalization analysis for these loci and estimated that the posterior probabilities of shared causal variants between AMD and CSC were 0.39 and 0.60 for WBP1L and GATA5, respectively. Genetic correlation analysis focusing on the epidemiologically suggested clinical risk factors implicated shared polygenic architecture between AMD and smoking cessation (rg [the measure of genetic correlation] = -0.33; P = 0.01; false discovery rate, 0.099). CONCLUSIONS: Our findings imply shared genetic components conferring the risk of both AMD and CSC. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

PURPOSE: To evaluate the efficacy of anterior segment optical coherent tomography (AS OCT) in estimating the length of the pars plana and optimizing the sclerotomy entry site in vitrectomy for highly myopic eyes, facilitating membrane peeling. METHODS: Twenty-three eyes with myopic traction maculopathy were studied. The pars plana was examined using two methods: preoperative AS OCT and intraoperative measurement. The distance from the limbus to the ora serrata in two groups was measured to compare differences in length. The actual length of the entry site from the limbus and forceps used were noted in all eyes studied. RESULTS: The mean axial length was 29.2 ± 2.3 mm for all 23 eyes. The average length between the limbus and ora serrata measured with AS OCT and intraoperative examination was 6,710 µ m (SD ± 459) and 6,671 µ m (SD ± 402), respectively, in the superotemporal region ( P > 0.05), and 6,340 µ m (SD ± 321) and 6,204 µ m (SD ± 402), respectively, in the superonasal region ( P >0.05). The mean length of the entry site from the limbus was 6.2 mm, and 28-mm forceps were used in 17 of 23 eyes (77%). CONCLUSION: The length of the pars plana varies depending on the axial length of the eye. Preoperative AS OCT enables accurate measurement of the pars plana in eyes with high myopia. AS OCT examination can help determine the optimal site for sclerotomy, allowing easier access to the macular region for membrane peeling in highly myopic eyes.

PURPOSE: This study aims to investigate the postoperative refractive outcomes in eyes that underwent the flanged intrascleral intraocular lens (IOL) fixation combined with vitrectomy with or without gas/air tamponade. METHODS: The eyes were divided into two groups (Group A; eyes that underwent flanged intrascleral IOL fixation with gas/air tamponade, and Group B; eyes that underwent flanged intrascleral IOL fixation without gas/air tamponade). The predicted spherical equivalent (SE) refraction values were calculated using the Sander-Retzlaff-Kraff Theoretical formula. Then, the prediction error was calculated by subtracting the predicted SE refraction from the postoperative objective SE refraction and the absolute prediction error was calculated as the absolute value of the prediction error for each eye. RESULTS: A total of 68 eyes were included in the current study. There was a significant correlation between the predicted and postoperative SE refraction in both groups (Group A, r = 0.968, P < 0.0001, Group B, r = 0.943, P < 0.0001, linear regression analysis). The prediction error demonstrated a mild myopic shift after the flanged intrascleral IOL fixation in both groups (Group A, -0.40 ± 0.96 diopter, Group B, -0.59 ± 0.95 diopter). There was no significant difference in prediction error and absolute prediction error between the two groups ( P = 0.44, P = 0.70, Wilcoxon rank sum test). CONCLUSION: The postoperative SE refraction after flanged intrascleral IOL fixation was not influenced by gas/air tamponade.

BACKGROUND: This study aimed to report eleven cases of non-neovascular pachychoroid disease with hyperreflective material (HRM) that occurred in Japanese patients. METHODS: A retrospective review of data from eleven patients who had non-neovascular retinal pigment epithelium (RPE) protrusion with HRM in the neurosensory retina between March 2017 and June 2022 was conducted. Clinical examination, color fundus photography, fluorescein angiography, spectral-domain optical coherence tomography (SD-OCT), and OCT angiography data were analyzed. Main outcome measures were patient characteristics, changes in SD-OCT findings, and symptom outcomes. RESULTS: All cases had RPE protrusion and HRM with dilated choroidal veins, which were characteristic of pachychoroid disease. However, none of the cases had macular neovascularization (MNV). In 9 eyes (81.8%), HRM improved spontaneously without intervention and resulted in alterations in RPE, referred to as pachychoroid pigment epitheliopathy (PPE) or focal choroidal excavation (FCE). In these cases, symptoms such as metamorphopsia and distortion improved without treatment. In the remaining two cases (18.2%), HRM still persisted during the follow-up period. CONCLUSION: There are some cases of non-neovascular pachychoroid disorder with HRM, which might be a new entity of pachychoroid spectrum disease or an early stage of PPE or FCE. These cases should not be misdiagnosed as MNV, and careful observation is necessary.

PURPOSE: Airbags have substantially reduced mortality and morbidity, while ocular injuries caused by airbags have been reported. We applied a three-dimensional finite element analysis (FEA) model we have established for evaluation of the deformation of an intact eyeball of various axial lengths induced by an airbag impact at various impact velocities. METHODS: A model human eye we have created was used in simulations with an FEA program, PAM-GENERIS™ (Nihon ESI, Tokyo, Japan). The airbag was set to impact eyes with various axial lengths of 21.85 mm (hyperopia), 23.85 mm (emmetropia) and 25.85 mm (myopia), at initial velocities of 30, 40, 50 and 60 m/s. Changes in the shape of the eye and the strain induced were calculated. Deformation of the eye in a cross-sectional view was displayed sequentially in slow motion. RESULTS: We found that considerable damage, such as corneal or scleral lacerations, was observed especially at higher impact velocities, such as 50 or 60 m/s, in eyes with any axial length. Deformation was most evident in the anterior segment. The decrease rate of axial length was greatest in the hyperopic eye, followed by the myopic eye, and the emmetropic eye. CONCLUSIONS: It was shown that hyperopic eyes are most susceptible to deformation by an airbag impact in this simulation. The considerable deformation by an airbag impact on the eye during a traffic accident shown in this study might indicate the necessity of ocular protection to avoid permanent eye damage.

PURPOSE: To analyze the vessel density around the optic nerve head (ONH) by optical coherence tomography angiography (OCTA) in patients with retinitis pigmentosa (RP), and to evaluate its correlation with visual functions. METHODS: Thirty-eight eyes with RP with visual field constriction within the central 10° were enrolled. The mean (± SD) age of the patients was 43.7 ± 15.1 years. In addition to visual acuity (VA) measurements and visual field tests (Humphrey Field Analyzer 10-2 test), we also measured the vessel density at the macula by OCTA (superficial and deep vessel density: sVD(m) and dVD(m)) and in multiple layers around the ONH (vessel density in the radial peripapillary capillary [RPC] layer and in the nerve head [NH] layer: VDrpc and VDnh). The vessel density was calculated by binarizing the OCTA images. The associations between the logMAR VA and mean deviation (MD) values and the variables of central retinal thickness (CRT), sVD(m), dVD(m), VDrpc, VDnh, and also the size of the foveal avascular zone were investigated. RESULTS: The mean logMAR VA was 0.16 ± 0.34 and the MD value was - 17.2 ± 10.3 dB; the MD value was significantly related to the logMAR VA (p = 0.0028). Multivariate analysis with AICc model selection suggested only dVD(m) was associated with logMAR VA. On the other hand, the optimal model for the MD value included the CRT, dVD(m), and VDnh. CONCLUSION: The vessel density in the deep layer around the ONH was significantly associated with the visual field deterioration in patients with RP.

PURPOSE: To predict changes in retinal sensitivity using optical coherence tomography (OCT) in eyes with central serous chorioretinopathy (CSC). METHODS: Twenty-three eyes in 23 patients with CSC were enrolled. Retinal sensitivity was measured twice using microperimetry in all the examined eyes. Spectral domain OCT measurements were simultaneously conducted. The relationship between retinal sensitivity and the thicknesses of (i) the retinal nerve fiber layer plus the ganglion cell layer (RNFL + GCL), (ii) the inner nuclear layer (INL), (iii) the outer nuclear layer (ONL), and (iv) the serous retinal detachment height (SRDH) were investigated in a point-wise manner. The associations between the change in retinal sensitivity and the OCT parameters at baseline were also investigated. RESULTS: The mean age of the participants was 49.8 ± 10.7 years. The mean SRDH was significantly lower (p < 0.001), and the mean retinal sensitivity (p < 0.001) was significantly higher at the second examination, compared with the first; however, the logMAR visual acuity (VA) did not differ significantly between the two examinations (p = 0.063). The logMAR VA was associated with retinal sensitivity at both the first and second examinations (p < 0.001). The retinal sensitivity at the second examination was significantly correlated with the retinal sensitivity, RNFL + GCL, INL, ONL, and SRDH at the first examination and with the improvement in SRDH. CONCLUSIONS: Retinal sensitivity was associated with the retinal structure in eyes with CSC; these parameters could be useful for predicting the change in visual function prior to treatment.

PURPOSE: To investigate the retinal light hazard during macular surgery using a digital three-dimensional visualization system (3D) and a conventional microscope (CM). DESIGN: Experimental study and retrospective evaluation of a case-control study. SUBJECTS: A total of 20 and 10 patients who underwent pars plana vitrectomy for epiretinal membrane using 3D and CM, respectively. METHODS: Spectral irradiances of endoilluminators were measured for representative settings used during core vitrectomy and macular manipulations with 3D and CM. From the medical record of the patients, time needed for core vitrectomy and macular manipulations was extracted. The total retinal light hazard index and the macular hazard index were calculated based on the spectral irradiances weighted by the standard functions. Total retinal light hazard index, macular hazard index, and the number of cases that exceeded the maximum permissible radiant power exposure were compared between the two groups. RESULTS: The spectral irradiance were 1.6 and 3.9 mW/cm 2 for core vitrectomy and 3.4 and 8.1 mW/cm 2 for macular manipulations using typical settings for 3D and CM groups, respectively. The total retinal light hazard index ranged from 4.31 kJ/m 2 to 17.37 kJ/m 2 for 3D and 11.09 kJ/m 2 to 27.70 kJ/m 2 for CM groups, respectively, whereas the macular hazard index ranged from 2.93 kJ/m 2 to 14.58 kJ/m 2 for 3D and from 6.84 kJ/m 2 to 23.55 kJ/m 2 for CM, respectively ( P < 0.001). One (5%) and 6 (60%) pars plana vitrectomy cases exceeded the threshold limits with 3D and CM groups, respectively ( P < 0.05, chi-square test). CONCLUSION: The 3D digitally assisted visualization system offers significantly safer macular surgery compared with the CM, considering the potential retinal hazard.

This study aimed to reveal the relationship between quality of life (QOL) and sleep quality in patients with type 1 diabetes mellitus (T1DM). Overall, 202 patients with T1DM were registered in our study, and 192 were eligible for analysis. Baseline characteristics and laboratory values were determined. Patients completed the Japanese versions of the Pittsburgh Sleep Quality Index (PSQI) and Diabetes Therapy-Related QOL (DTR-QOL) questionnaires. We investigated the relationship between the global PSQI and DTR-QOL total scores by using linear regression analysis. In univariate regression analysis, DTR-QOL total scores were associated with body mass index, alcohol consumption, hypertension, hemoglobin A1c (HbA1c), and global PSQI score (all p-value <0.05) but not with sleep duration. When the association between PSQI subscales and DTR-QOL total scores was examined, DTR-QOL total scores were significantly related to subjective sleep quality and daytime dysfunction. In a multivariate regression analysis, the global PSQI score was negatively related to DTR-QOL total scores. Patients with an HbA1c concentration ≥8.0% had significantly lower DTR-QOL total scores. We revealed a relationship between QOL and sleep quality in T1DM patients and showed that the relationship between QOL and PSQI subscales in T1DM patients may be different from that in patients with type 2 diabetes mellitus. Assessing and managing sleep quality may be necessary for patients with diabetes to improve QOL.

PURPOSE: To report the anatomic and functional outcomes of autologous retinal transplantation (ART). DESIGN: Multicenter, retrospective, interventional, consecutive case series. PARTICIPANTS: One hundred thirty eyes of 130 patients undergoing ART for the repair of primary and refractory macular holes (MHs), as well as combined MH-rhegmatogenous retinal detachment (MH-RRD), between January 2017 and December 2019. METHODS: All patients underwent pars plana vitrectomy and ART, with surgeon modification of intraoperative variables. A large array of preoperative, intraoperative, and postoperative data was collected. Two masked reviewers graded OCT images. Multivariate statistical analysis and subgroup analysis were performed. MAIN OUTCOME MEASURES: Macular hole closure rate, visual acuity (VA), external limiting membrane and ellipsoid zone (EZ) band integrity, and alignment of neurosensory layers (ANL) on OCT. RESULTS: One hundred thirty ART surgeries were performed by 33 vitreoretinal surgeons worldwide. Patient demographics were: mean age of 63 ± 6.3 years, 58% female, 41% White, 23% Black, 19% Asian, and 17% Latino. Preoperative VA was 1.37 ± 0.12 logarithm of the minimum angle of resolution (logMAR; Snellen equivalent, approximately 20/500), which improved significantly to 1.05 ± 0.09 logMAR (Snellen equivalent, approximately 20/225; P < 0.001) after surgery (mean follow-up, 8.6 ± 0.8 months). Autologous retinal transplantation was performed for primary MH repair in 27% of patients (n = 35), for refractory MH in 58% of patients (n = 76; mean number of previous surgeries, 1.6 ± 0.2), and for MH-RRD in 15% of patients (n = 19). Mean maximum MH diameter was 1470 ± 160 µm, mean minimum diameter was 840 ± 94 µm, and mean axial length was 24.6 ± 3.2 mm. Overall, 89% of MHs closed (78.5% complete; 10% small eccentric defect), with a 95% closure rate in MH-RRD (68.4% complete; 26.3% small eccentric defect). Visual acuity improved by at least 3 lines in 43% of eyes and by at least 5 lines in 29% of eyes. Reconstitution of the EZ (P = 0.02) and ANL (P = 0.01) on OCT were associated with better final VA. Five cases of ART graft dislocation (3.8%), 5 cases of postoperative retinal detachment (3.8%), and 1 case of endophthalmitis (0.77%) occurred. CONCLUSIONS: In this global experience, patients undergoing ART for large primary and refractory MHs and MH-RRDs achieved good anatomic and functional outcomes, with low complication rates despite complex surgical pathologic features.

PURPOSE: To evaluate the relationship between the number of laser shots applied during laser photocoagulation treatment and the degree of myopia at 3 years in children with laser-treated retinopathy of prematurity (ROP). METHOD: A total of 68 eyes of 34 infants who had developed prethreshold ROP and were treated by diode laser therapy were included in the current study. Cycloplegic retinoscopic refraction testing was performed in the children at the age of 3 years, and the spherical equivalent (SE) was calculated for all the examined eyes. The number of laser shots that had been applied was compared between the eyes with and without high myopia (SE < - 5 diopters (D)). In addition, the relationship between the difference in the SE values between the two eyes in each infant and the difference in the number of laser shots applied between the two eyes was also analyzed. RESULTS: The number of laser shots applied was significantly higher for the eyes with high myopia than for those without high myopia (p = 0.0088), and the number of laser shots applied was significantly positively correlated with the degree of myopia (p < 0.001). A significant correlation was also observed between the differences in the SE values between the two eyes and the differences in the number of laser shots applied between the two eyes (p = 0.0013). CONCLUSION: The number of laser shots applied in photocoagulation treatment for ROP is significantly associated with the degree of myopia seen subsequently in the children.

PURPOSE: To identify the functional outcome and evaluate the morphologic changes of patients with pachychoroid neovasculopathy (PNV) undergoing intravitreal anti-vascular endothelial growth factor (VEGF) combined with photodynamic therapy (PDT) at the 1-year follow-up. METHODS: We retrospectively studied all the treatment-naïve PNV patients who were scheduled to undergo combination therapy between September 2017 and November 2018. All the patients received three consecutive monthly injections of 0.5 mg/0.05 mL ranibizumab as loading doses. Full-dose PDT was performed within 1 week of the first injection. Retreatment was allowed if evidence of clinical deterioration or the presence of fluid on spectral-domain optical coherence tomography examination performed at the 1-month follow-up was noted. The best-corrected visual acuity (BCVA) was compared before treatment and at 3, 6, and 12 months after the initial treatment. Changes in the central foveal thickness (CFT), central choroidal thickness (CCT), and retreatment rate during the maintenance phase were also evaluated. RESULTS: Eleven eyes were enrolled in this study. Significantly, better BCVA was observed at 12 months than at baseline (P = 0.010). The mean CFT significantly decreased from 331 ± 93 to 237 ± 72 µm at 12 months (P < 0.001). The mean CCT also significantly decreased from 361 ± 74 to 310 ± 83 µm at 12 months (P < 0.001). The mean number of injections per eye was 3.9 ± 1.3 during the follow-up period. A total of 45.5% (5 /11) of the patients required retreatment during the maintenance phase. CONCLUSION: Anti-VEGF combined with full-dose PDT was well tolerated and appeared to be effective treatment for patients with treatment-naïve PNV. Combination therapy might also reduce the treatment burden with fewer injections in patients with PNV.

PURPOSE: To report the outcomes of autologous neurosensory retinal transplant as a primary treatment for patients with large chronic macular holes and evaluate the safety and feasibility of the procedure. DESIGN: Retrospective study, consecutive case series. METHODS: We reviewed seven patients with a primary chronic large macular hole, who underwent autologous neurosensory retinal transplant. Mean preoperative minimum and maximum hole diameters were 643 µm and 1214 µm, respectively. Changes in visual acuity were measured postsurgery, and optical coherence tomography, fluorescein angiography, and microperimetry-3 were analyzed after the procedure. RESULTS: Closure of the macular hole was achieved in all seven eyes in the study. At 1 year post-surgery, there was significant improvement in mean visual acuity (LogMAR 1.10 vs. 0.68, P = 0.001). Optical coherence tomography showed that all grafts had formed attachments to the retinal epithelial cells of the recipient retina. Mean preoperative ellipsoid zone defect was 1,089 ± 403.8 µm (range, 918-1,329 µm) which further decreased to 921 ± 129.1 µm (range, 670-1,201 µm) at final follow up (P = 0.09). Microperimetry-3 testing indicated retinal sensitivity in the graft in five eyes. CONCLUSION: Autologous retinal transplantation may help rebuild the macular structure resulting in functional improvement for eyes with primary chronic large macular hole.

PURPOSE: To report the structural and functional outcomes of autologous neurosensory retinal transplant for closure of refractory large macular holes (MHs). DESIGN: Multicenter, retrospective, consecutive case series. PARTICIPANTS: A total of 41 eyes of 41 patients with a full-thickness MH refractory to prior vitrectomy with internal limiting membrane (ILM) peel and tamponade. METHODS: All patients underwent pars plana vitrectomy, autologous neurosensory retinal transplant with gas, silicone oil tamponade, or short-term perfluoro-n-octane heavy-liquid tamponade. All patients had at least 6 months' follow-up. MAIN OUTCOME MEASURES: Anatomic closure of MH, change in ellipsoid zone (EZ) and external limiting membrane (ELM) defect on OCT, visual acuity (VA) recovery, and surgical complications were analyzed. RESULTS: Mean number of prior surgeries was 1.5±0.94 (range, 1-3), and patients were followed for a mean of 11.1±7.7 months (range, 6-36 months). Complete anatomic closure of MH by OCT was achieved in 36 of 41 eyes (87.8%). Mean corrected VA (logarithm of the minimum angle of resolution [logMAR]) improved (P = 0.03) from 1.11±0.66 (range, 0.48-3) to 1.03±0.51 (range, 0.1-2) at the last postoperative visit. The VA improved (≥0.3 logMAR units) in 15 eyes (36.6%), was stable in 17 eyes (41.5%), and worsened in 9 eyes (21.9%). Among eyes with anatomic closure, VA improved in 52.3% and worsened in 13.8%, whereas in those without closure, VA worsened in 40% and improved in none. Mean preoperative largest basal diameter was 1468.1±656.4 µm (range, 621-2600 µm), and mean inner-opening diameter was 825±422.5 µm (range, 336-1649 µm). Mean preoperative EZ defect was 1777.3±513.8 µm (range, 963-2808 µm), which decreased to 1370±556.9 µm (range, 288-2000 µm) at final follow-up (P = 0.007). Mean preoperative ELM was 1681.5±429 µm (range, 1172-2606 µm), which decreased to 1408.5±571.2 µm (range, 200-2000 µm) at final follow-up (P = 0.017). Major postoperative complications were retinal detachment (n = 1) and vitreous hemorrhage (n = 1). There were no cases of proliferative vitreoretinopathy, endophthalmitis, suprachoroidal hemorrhage, or choroidal neovascularization. CONCLUSIONS: The autologous retinal transplant technique offers a high degree of anatomic success and proved safe in this initial experience for closure of refractory MHs.

OBJECTIVE: Diagnosing obstructive sleep apnea (OSA) usually involves high cost, patient inconvenience, and the need for examination at a specialized center. This study employed a portable, wearable, diagnostic device (WatchPAT) to investigate the prevalence of OSA in nonobese Japanese patients with type 2 diabetes. METHODS: Patients with type 2 diabetes were tested for OSA over one night using the WatchPAT. Logistic regression analysis was used to estimate the odds ratios (ORs) of risk factors for OSA in nonobese subjects. RESULTS: A total of 200 eligible patients with type 2 diabetes were studied (64.5% men; aged 60.1 ± 13.6 years; body mass index [BMI], 26.3 ± 5.2 kg/m2). When OSA was defined as apnea-hypopnea index ≥5/hour, its prevalence was 80.5%. The prevalence of OSA in subjects with a BMI <20 kg/m2, ≥20 and <25 kg/m2, ≥25 and <30 kg/m2, and ≥30 kg/m2 was 38.9%, 73.5%, 86.5%, and 97.5%, respectively. The severity of OSA increased in proportion to BMI, especially when the BMI was >25 kg/m2. The prevalence of OSA was also high (66.3%) in normal-weight subjects (BMI <25 kg/m2). Furthermore, the serum triglyceride level (OR, 1.01; 95% confidence interval, 1.00 to 1.02; P = .042) was significantly related to OSA. CONCLUSION: A high prevalence of OSA was observed in this nonobese population of Japanese patients with type 2 diabetes. The triglyceride level was associated with OSA among nonobese patients.
