Abstract
A second-order voltage-controlled oscillator (VCO)-based continuous-time sigma-delta modulator (CTSDM) for current-sensing readout applications is proposed. Current signals from the sensor can directly be quantized by the proposed VCO-based CTSDM, which does not require any extra trans-impedance amplifiers. With the proportional-integral (PI) structure and a VCO phase integrator, the capability of second-order noise shaping is available to reduce the in-band quantization noise. The PI structure can be simply realized by a resistor in series with the integrating capacitor, which can reduce the architecture complexity and maintain the stability of the system. The current-steering digital-to-analog converter with tail and sink current sources is used on the feedback path for the subtraction of the current-type input signal. All the components of the circuit are scaling friendly and applicable to current-sensing readout applications in the Internet of Things (IoT). The proposed VCO-based CTSDM implemented in a 0.18-μm standard CMOS process has a measured signal-to-noise and distortion ratio (SNDR) of 74.6 dB at 10 kHz bandwidth and consumes 44.8 μw only under a supply voltage of 1.2 V, which can achieve a Figure-of-Merit (FoM) of 160.76 dB.

Abstract
PURPOSE This study aims to describe the structural changes and surgical outcomes of full-thickness macular holes (FTMHs) induced by vitreomacular traction with broad vitreomacular attachment (VMA). METHODS A retrospective analysis of idiopathic FTMHs from October 2010 to May 2022 was conducted. Patients with FTMHs and no retinal detachment (RD) induced by broad VMA (the study group) were compared with a control group consisting of typical FTMHs with focal VMA. RESULTS Thirty-one eyes had broad VMA-associated FTMH, among which seven eyes (22%) were with concurrent RD. Among the total of 24 cases without RD, 8 (33%) exhibited schisis. The incidence of lamellar holes associated epithelial proliferation and multiple membrane traction was significantly higher in the study group. One hundred percent FTMH closure was observed postoperatively in both groups. Although the postoperative visual acuity was not significantly different, the study group showed a greater ellipsoid zone disruption length. CONCLUSION Broad VMA-induced FTMHs are characterized by diverse macular structural changes, including schisis and macular detachment. These FTMHs are associated with a higher incidence of lamellar holes associated epithelial proliferation and multiple membrane traction. Surgical outcomes for FTMHs induced by broad VMA are similar to those induced by typical focal VMA, with both groups demonstrating a 100% hole-closure rate.

Abstract
PURPOSE To analyze the associations between development of age-related macular degeneration (AMD) and regular use of aspirin or non-aspirin non-steroidal anti-inflammatory drugs (NA-NSAIDs). METHODS We retrospectively recruited individuals who received ≥28-day prescriptions of aspirin or NA-NSAIDs exclusively between 2008 and 2017 in one tertiary center as regular users. Non-regular users were free from regular use of any anti-inflammatory drugs and were matched to regular users in terms of age, sex, and visit date at a ratio of 1-4:1. The aspirin cohort included 36,771 regular users and 110,808 matched non-regular users, while the NA-NSAID cohort included 59,569 regular users and 179,732 matched non-regular users. Stratified multivariate Cox regression analyses with adjustment for systemic confounding factors were performed for the development of AMD and neovascular AMD. RESULTS In the aspirin cohort, the adjusted hazard ratios of aspirin use for AMD in the whole cohort, individuals without cardiovascular diseases (CVDs), and those with CVDs were 0.664, 0.618, and 0.702, respectively (P < 0.0001 for all), while those of aspirin use for neovascular AMD were 0.486, 0.313, and 0.584 (P < 0.05 for all), respectively. In the NA-NSAID cohort, regular use of NA-NSAIDs was associated with a decreased risk of AMD (hazard ratio = 0.823, P < 0.0001) and neovascular AMD (hazard ratio = 0.720, P = 0.040) only in people without arthritis. CONCLUSIONS Regular use of aspirin or NA-NSAIDs had protective effects on AMD and neovascular AMD. The effect of aspirin was observed in all patients, while the effect of NA-NSAIDs was observed only in people without arthritis.

Abstract
This study aimed to investigate the characteristic choroidal changes in patients with diabetic retinopathy and identify factors affecting choroidal thickness (CTh), choroidal vascular index (CVI), and choriocapillaris flow. We retrospectively analyzed 79 eyes of 48 patients with diabetes between August 2021 and February 2022. We collected laboratory data, including HbA1c, serum creatinine, blood urea nitrogen, triglyceride, total cholesterol, high-density lipoprotein, and low-density lipoprotein (LDL) levels. Optical coherence tomography images of the foveal avascular zone, retinal vascular density, choroidal flow, retinal thickness, CTh, and CVI were analyzed. Possible determining factors affecting CTh, CVI, and choriocapillaris flow were analyzed using nonparametric multivariate analysis. LDL (p < 0.001) positively correlated with CTh, whereas CVI (p = 0.007) was negatively correlated with CTh in diabetic patients with diabetes. We also identified a negative correlation between choriocapillaris flow and deep parafoveal retinal vessel density in patients with low-grade diabetic retinopathy (DR), which diminished in those with more advanced DR. Our study provides further information on the changes in choroidal structure and blood flow in patients with diabetes.

Abstract
PURPOSE Vitreomacular traction (VMT) has unique presentations in eyes with diabetic retinopathy (DR). This study aimed to investigate the characteristics and clinical course of VMT in DR. STUDY DESIGN A retrospective case series. METHODS Thirty eyes from 30 patients with DR and concurrent VMT were retrospectively enrolled. Baseline and final best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) characteristics were reported. Linear regression models were used to analyze the correlating factors for visual outcome. RESULTS Of the 30 eyes, a thickened posterior hyaloid membrane was noted in all cases and multi-layered traction from different directions in 14 eyes (46.7%). Twenty-one eyes (70%) had tractional macular retinoschisis, seven (23.3%) had foveal detachment, five (16.7%) had a lamellar macular hole, and three (10%) had a full-thickness macular hole, including two with macular hole retinal detachment. Three eyes had spontaneous release of the VMT within 3 months of observation. For the remaining 27 eyes receiving operations, the VMT, full-thickness macular hole, and serous foveal detachment all resolved postoperatively with residual macular schisis in 6 eyes (22.2%) only. None of the baseline OCT characteristics were associated with postoperative BCVA (P > .05). CONCLUSIONS VMT in DR had a thickened posterior hyaloid, and many of them had multi-layered traction and/or concurrent macular retinoschisis. Lamellar macular hole, full-thickness macular hole, or concurrent retinal detachment may also occur. Spontaneous resolution of VMT rarely occurred, and those who underwent operation for VMT had improved vision and macular structures with resolution of the macular hole and retinal detachment.

Abstract
Rhegmatogenous retinal detachment (RRD) is a significant cause of vision loss and requires appropriate surgical intervention. There are several approaches available, including observation, laser demarcation, pneumatic retinopexy, scleral buckling, and pars plana vitrectomy, which are chosen based on patient condition, surgeon experience, and national health insurance policies. Despite the various options, there is still no consensus on the optimal intervention. To address this, the Taiwan Retina Society assembled an expert committee with 11 experienced retina specialists to review the current evidence and develop a guideline with seven recommendations for managing RRD patients. Additionally, a survey was conducted with six questions to assess treatment patterns in Taiwan, which included input from the expert committee and an open poll at the 2023 Congress of the Taiwan Retina Society. This report provides a comprehensive summary of the current knowledge and expert consensus on the treatment of RRD, discussing the characteristics of current approaches and providing an overview of current treatment patterns in Taiwan. These findings aim to provide ophthalmologists with the best possible treatment for RRD.

Abstract
Clinical practices on acute post-operative and endogenous endophthalmitis (EnE) are highly variable among clinicians due to a lack of up-to-date, high-quality evidential support. An expert consensus is thus much needed. A panel consisting of ten retinal specialists in Taiwan was organized. They evaluated relevant literature and developed key questions regarding acute post-operative and EnE that are cardinal for practice but yet to have conclusive evidence. The panel then attempted to reach consensus on all the key questions accordingly. There were eight key questions proposed and their respective consensus statements were summarized as follows: Gram staining and culture are still the standard procedures for the diagnosis of endophthalmitis. Vitrectomy is recommended to be performed earlier than the timing proposed by the Endophthalmitis Vitrectomy Study (EVS). Routine intracameral antibiotic injection for post-cataract surgery endophthalmitis prophylaxis is not recommended because of potential compounding error hazards and a lack of support from high-quality studies. Routine fundus examination is recommended for all patients with pyogenic liver abscess. In EnE, vitrectomy is recommended if diffused and dense vitritis is present, or if the disease progresses. These consensus statements may work as handy guidance or reference for clinical practices of acute post-operative and EnE.

Abstract
INTRODUCTION To evaluate the real-world efficacy of aflibercept using the treat-and-extend (TnE) regimen in treating neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV), and to analyze biomarkers using optical coherence tomography (OCT) to predict treatment outcomes. METHODS Patients diagnosed with nAMD or PCV who received an intravitreal injection of aflibercept following the TnE regimen for ≥ 2 years were retrospectively reviewed. Data on best-corrected visual acuity (BCVA), number of injections, treatment interval, and OCT biomarkers, including central macular thickness, presence of subretinal fluid (SRF), and serous pigmented epithelial detachment, were collected at baseline and at 3, 6, 12, 18, and 24 months after the first injection. RESULTS A total of 43 patients were enrolled in this study, 24 of whom were diagnosed with nAMD and 19 with PCV. The BCVA in logMAR (mean ± standard deviation) improved from 0.75 ± 0.41 (baseline) to 0.60 ± 0.41 (P = 0.002) at 3 months after treatment initiation, and further improved to 0.66 ± 0.46 at 24 months (P = 0.137). The number of injections (mean ± standard deviation) within the 2-year treatment course was 10.95 ± 3.65. At month 24 of the TnE regimen, the treatment interval was extended to ≥ 16 weeks in 60.5% of all cases and to 78.9% of the PCV cases. After three loading injections, persistent subretinal fluid and intraretinal fluid were predictive of more frequent injections (P = 0.026) and poorer visual outcomes (P = 0.050), respectively. CONCLUSION Aflibercept combined with a TnE regimen was effective in treating nAMD and PCV in a real-world setting. The treatment interval could be extended to ≥ 16 weeks in 60.5% of the cases after a 2-year treatment regimen. OCT can be used to predict the treatment course and visual outcomes.

Abstract
AIMS To measure the foveal pit morphology parameters and evaluate their correlations with age and sex. SETTINGS AND DESIGN A retrospective cross-sectional matched comparison study in a tertiary center. METHODS AND MATERIALS Forty men and 40 age-matched women who had normal macular structures and foveal contours were enrolled. Foveal pit parameters including top width, base width, nasal width, temporal width, minimal thickness, nasal thickness, temporal thickness, nasal height, temporal height, nasal slope, and temporal slope were measured on horizontal B-scan macular optical coherence tomography and compared between men and women. STATISTICAL ANALYSIS USED Paired t-tests and Pearson's correlation analysis. RESULTS The average patient age was 51.4 ± 17.5 (21-84) years. Women had a wider base width (313.1 ± 68.0 μm vs 266.8 ± 70.9 μm, P = 0.006), wider temporal width (1043.1 ± 245.6 μm vs 968.9 ± 261.0 μm, P = 0.006), thinner nasal thickness (345.6 ± 36.2 μm vs 359.7 ± 35.8 μm, P = 0.048), and flatter temporal slope (11.60 ± 2.52° vs 12.98 ± 2.68°, P = 0.016) than men. With age, the base width (r = 0.35, P = 0.025) and temporal width (r = 0.54, P = 0.0003) tended to be wider and the temporal slope was flatter (r = -0.45, P = 0.003) in women but not men. The minimal thickness tended to be thinner in the elderly group (r = 0.038, P = 0.015). CONCLUSIONS Women had a significantly wider base width, wider temporal width, thinner nasal thickness, and flatter temporal slope of the foveal pit than age-matched men. The base width and temporal width were wider and the temporal slope was flatter with age in women but not men.

Abstract
Individuals with autism spectrum disorder (ASD) often exhibit joint hypermobility and connective tissue disorders. However, it remains unclear if ASD individuals also have structural alterations in the connective tissue of the cornea. This study aims to determine whether the Kobayashi structure (K-structure) characteristics differ between adults with ASD and typically developing controls (TDC) and explore the clinical correlates of the K-structure abnormality. We recruited 30 ASD adults and 35 TDC. Corneal structures, particularly the K-structure in the Bowman's layer, of the participants were examined using in vivo confocal microscopy (IVCM), and a K-grading ranging from 1 to 4 was given to each eye based on the level of morphological mosaicism. The ASD participants' eyes received a significantly higher single-eye K-grading than that of the TDC eyes (p < 0.001), and the medians [25th, 75th percentile] of bilateral-eye summed K-grading were 8 [7, 8] and 5 [4, 6] in ASD and TDC, respectively (p < 0.001). A significantly higher K-grading in the ASD participants' eyes was still observed after adjusting for the within-subject inter-eye correlation (p < 0.001). Youden Index showed the optimal cutoffs to differentiate ASD from TDC by bilateral-eye summed K-grading and single-eye K-grading was >6 and >3, respectively. Additionally, a higher K-grading was associated with fewer visual sensation seeking in ASD (Spearman's correlation coefficient ρ = -0.518, p = 0.008) and low visual registration (i.e., higher sensory threshold) in TDC (ρ = 0.446, p = 0.023). This study provided novel evidence of corneal structural alterations in ASD by IVCM. Our findings may not only support the prior hypothesis of the association between ASD and connective tissue abnormalities but also shed light on the relationship between connective tissue disorder and neurodevelopmental disorders.

Abstract
INTRODUCTION To investigate the longitudinal changes in renal function and associated factors after intravitreal anti-vascular endothelial growth factor (VEGF) administration in diabetic macular edema (DME). METHODS A total of 108 patients who had received intravitreal ranibizumab or aflibercept for DME and had follow-up visits for at least 2 years in one hospital were retrospectively enrolled. The estimated glomerular filtration rate (eGFR) at baseline and during the follow-up period and receipt of any renal replacement therapy were recorded. Linear regression and Cox regression models were used to evaluate factors associated with eGFR decline and renal replacement therapy. RESULTS After intravitreal anti-VEGF treatment, eGFR showed a mean decline of -10.4 ± 23.2% and -16.5 ± 26.4% at months 12 and 24, respectively. Patients in the eGFR > 120 mL/min and 15-30 mL/min groups had the greatest decline (-32.0 ± 20.6% and -37.4 ± 30.9%, respectively) while those in the 61-90 mL/min group had the smallest decline (-4.3 ± 19.7%) in eGFR after the 2-year treatment. One out of 52 patients (1.9%) receiving ranibizumab and five out of 56 patients (8.9%) receiving aflibercept started hemodialysis or peritoneal dialysis within the 2-year follow-up period (P = 0.21). Baseline eGFR correlated with renal replacement therapy after intravitreal anti-VEGF treatment (hazard ratio = 0.879 per increase of 1 in eGFR, P = 0.018). CONCLUSIONS In DME patients receiving intravitreal anti-VEGF treatment, a persistent decline in eGFR was observed during the 2-year treatment course. Patients with extremely high or low eGFR had greater eGFR decline, and those with poor baseline eGFR tended to require dialysis after intravitreal anti-VEGF treatment.

Abstract
BACKGROUND/PURPOSE The small retinal vessels reflect cerebral microcirculation and its fractal dimension (Df), representing the complexity of the retinal microcirculation. However, the connection between retinal circulation and cognitive function lacked consistent and longitudinal evidence. This study aimed to explore the association between retinal vascular complexity and cognitive impairment over time in non-demented community-dwelling older adults. METHODS This four-year prospective cohort study (2015-2019) is part of the ongoing Taiwan Initiative for Geriatric Epidemiological Research (TIGER, 2011 to present). Of the 434 older adults (age >65) recruited, 207 participants were included for analysis. The retinal vascular Df was assessed by baseline images from fundus photography (2015-2017). Global (Montreal Cognitive Assessment-Taiwanese version, MoCA-T) and domain-specific cognition were assessed at the baseline and 2-year follow-up (2017-2019). The multivariable linear regression models and generalized linear mixed models were used to evaluate the association of Df with cognitive decline/impairment over time. RESULTS Decreased left retinal vascular complexity was associated with poor attention performance (β = -0.40). As follow-up time increased, decreased vascular complexity was associated with poor memory performance (right: β = -0.25; left: β = -0.19), and decreased right vascular complexity was associated with poor attention performance (β = -0.18). CONCLUSION Low retinal vascular complexity of the right or left eye may be differentially associated with cognitive domains in community-dwelling older adults over two years. The retinal vascular Df of either eye may be served as a screening tool for detecting cognitive impairment in the preclinical phase of dementia.

Abstract
PURPOSE To investigate the single-dose effect of intravitreal dexamethasone (DEX) implant for patients with post-vitrectomy macular edema (ME) under silicone oil (SO) tamponade. METHODS Twelve eyes diagnosed with ME after undergoing pars plana vitrectomy with SO injections were retrospectively reviewed. Each eye received a single intravitreal DEX implant (0.7-mg, Ozurdex; Allergan Inc) injection as treatment for recalcitrant ME. Best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) were recorded. RESULTS Compared with baseline (1.24 ± 0.34), the mean LogMAR BCVA improved at 1 (1.14 ± 0.27), 3 (1.13 ± 0.22), and 6 (1.22 ± 0.30) months without statistical significance. Maximal CMT resolution was observed at 1 month after intravitreal injection. The CMT value improved significantly at 1 (P = .008), 3 (P = .006), and 6 (P = .009) months. IOP did not show significant elevation during follow-up. No serious adverse events were observed. CONCLUSION Single-dose treatment of DEX implant may have benefit for recalcitrant post-vitrectomy ME under SO tamponade.

Abstract
BACKGROUND This study aims to investigate the rationality of the allocation guidelines in a hepatitis B endemic area that uses corneas from hepatitis B donors. METHODS Under Taiwan's current guidelines, corneas donated from hepatitis B surface antigen (HBsAg)(+) donors can be allocated to HBsAg(+) or hepatitis B surface antibody recipients. From January 1, 2015, to December 31, 2019, corneas donated to National Taiwan University Hospital were divided into HBsAg(+), HBsAg(-)/hepatitis B core antibody (anti-HBc)(+), and HBsAg(-)/anti-HBc(-) groups. Hepatitis B virus (HBV) DNA extracted from corneoscleral rims was quantified by polymerase chain reaction and correlated with donor serum HBsAg, anti-HBc, and HBV DNA. Recipients of HBV DNA(+) grafts were called back for serology and serum HBV DNA tests. RESULTS The corneoscleral HBV DNA of 170 corneas (113 donors) was quantified, of which 45 corneas were from 28 HBsAg(+) donors, 87 were from 57 HBsAg(-)/anti-HBc(+) donors, and 38 were from 28 HBsAg(-)/anti-HBc(-) donors, and HBV DNA was detected in 80.0%, 9.2%, and 0% of the corneoscleral rims in each group. Donor anti-HBc(+) provided the highest sensitivity (1.00) and negative predictive value (1.00) for corneoscleral HBV DNA. Twenty-eight of 40 recipients (70%) using HBV DNA(+) grafts were called back, and none developed hepatitis in follow-up periods ranging from 6 to 55.5 mo. CONCLUSIONS Donor anti-HBc should be tested routinely with HBsAg. Allocating corneas from HBsAg(+) or anti-HBc(+) donors to HBsAg(+) or hepatitis B surface antibody recipients maximizes cornea usage from hepatitis B donors without compromising transplant safety in a hepatitis B endemic setting.

Abstract
Two-dimensional metal-organic framework (MOF) composites were produced by incorporating Fe-MOFs into reduced graphene oxide (rGO) nanosheets to form Fe-MOF/rGO composites by hydrothermal synthesis. SEM, TEM, XRD, XPS, and measurements of contact angles were used to characterize the composites. TEM studies revealed that the rod-like-shaped Fe-MOFs were extensively dispersed on the rGO sheets. Incorporating Fe-MOF into rGO significantly improves performance due to the large surface area, chemical stability, and high electrical conductivity. The response signals for the electrochemical sensing performance of Fe-MOF/rGO-modified electrodes to nitrofurazone (NFZ) were significantly enhanced. Differential pulse voltammetry was used to detect the NFZ, and the MOF/rGO sensor possesses a lower detection limit (0.77μM) with two dynamic ranges from 0.6-60 to 128-499.3 μM and high sensitivity (1.909 μA·mM-1·cm-2). Moreover, the anti-interference properties of the sensor were quite reproducible and stable. To understand the mechanism responsible for the enhanced sensing performance of the composite, grand canonical Monte Carlo calculations were performed for Fe-MOF/rGO composites with five unit cells of Fe-MOF and four layers of rGO. We attributed the improvement to the fact that the interface between the Fe-MOF and rGO absorbed increased NFZ molecules. The findings reported herein confirm that such Fe-MOF/rGO composites have significantly improved electrochemical performance and practical applicability of sensing nitrofurazone.

Abstract
BACKGROUND To demonstrate the associations between the morphology of macular retinal vasculature and disease severity of idiopathic epiretinal membrane (ERM). METHODS Macular structures were assessed using optical coherence tomography (OCT), and were classified as "with pseudohole" or "without pseudohole". The 3 × 3 mm macular OCT angiography images were analyzed using the Fiji software to obtain the vessel density, skeleton density, average vessel diameter, vessel tortuosity, fractal dimension, and foveal avascular zone (FAZ)-related parameters. The correlations between these parameters and ERM grading as well as visual acuity were analyzed. RESULTS For ERM with or without a pseudohole, increased average vessel diameter, decreased skeleton density, and decreased vessel tortuosity were all associated with inner retinal folding and thickened inner nuclear layer, indicating more severe ERM. In 191 eyes without a pseudohole, the average vessel diameter increased, fractal dimension decreased and vessel tortuosity decreased with increasing ERM severity. The FAZ was not associated with ERM severity. Decreased skeleton density (r = -0.37), vessel tortuosity (r = -0.35), and increased average vessel diameter (r = 0.42) were correlated with worse visual acuity (All P < 0.001). In 58 eyes with pseudoholes, a larger FAZ was associated with a smaller average vessel diameter (r = -0.43, P = 0.015), higher skeleton density (r = 0.49, P < 0.001), and vessel tortuosity (r = 0.32, P = 0.015). However, none of the retinal vasculature parameters correlated with visual acuity and central foveal thickness. CONCLUSION Increased average vessel diameter, decreased skeleton density, decreased fractal dimension and decreased vessel tortuosity were good indicators of ERM severity and associated visual impairment.

Abstract
INTRODUCTION To investigate changes in the vitreoretinal interface after anti-vascular endothelial growth factor (anti-VEGF) treatment in highly myopic eyes. METHODS Eyes with myopic choroidal neovascularization (mCNV) treated with intravitreal injection of anti-VEGF in a single-center were retrospectively reviewed. Fundus abnormalities and features of optical computed tomography were studied. RESULTS A total of 295 eyes from 254 patients were recruited to the study. Prevalence of myopic macular retinoschisis (MRS) was 25.4%, and the rates of progression and onset of MRS were 75.9% and 16.2%, respectively. Outer retinal schisis (β = 8.586, p = 0.003) and lamellar macular hole (LMH) (β = 5.015, p = 0.043) at baseline were identified risk factors for progression and onset of MRS, whereas male sex (β = 9.000, p = 0.039) and outer retinal schisis at baseline (β = 5.250, p = 0.010) were risk factors for MRS progression. Progression of MRS was first detected in outer retinal layers in 48.3% of eyes. Thirteen eyes required surgical intervention. Spontaneous improvements of MRS were observed in five eyes (6.3%). CONCLUSION Changes in the vitreoretinal interface, such as progression, onset, and improvement of MRS, were observed after anti-VEGF treatment. Outer retinal schisis and LMH were risk factors of progression and onset of MRS after anti-VEGF treatment. Intravitreal injection of ranibizumab and retinal hemorrhage were protective factors for surgical intervention for vision-threatening MRS.

Abstract
INTRODUCTION Intravitreal dexamethasone and anti-vascular endothelial growth factor (anti-VEGF) medications have revolutionized ocular disease management and favorable ocular safety profiles, but few studies have compared their systemic adverse events (SAEs). This study investigated the SAEs of intravitreal dexamethasone and anti-VEGFs by using real-world data. METHODS This retrospective cohort study sourced medical records from the largest multi-institutional database in Taiwan. Patients who received intravitreal dexamethasone (n = 137) or anti-VEGFs (n = 10,345) between 2014 and 2019 were enrolled. Propensity score matching was performed to achieve homogeneity between the two groups. Subdistribution hazard ratios (SHRs) and 95% confidence intervals (CIs) were calculated using the Fine-Gray model. Systemic as well as ocular clinical events and systemic biomarkers after 1-year follow-up were compared. RESULTS Both groups demonstrated comparable risks of major cardiac adverse events (SHR 1.57, 95% CI 0.29-8.55), heart failure (SHR 0.62, 95% CI 0.07-5.33), major bleeding (SHR 0.23, 95% CI 0.03-1.77), all-cause admission (SHR 0.73, 95% CI 0.41-1.30), and all-cause death (SHR 2.11, 95% CI 0.35-12.71). There were no significant differences in longitudinal changes in systolic and diastolic blood pressure, glycated hemoglobin, low-density lipoprotein, estimated glomerular filtration rate, or alanine aminotransferase between the groups. Both groups had a similar incidence of cataract surgery. Although the dexamethasone group exhibited a relatively high prevalence of antiglaucomatous medication use, there was not a significantly higher incidence of glaucoma surgery. CONCLUSION Intravitreal dexamethasone and anti-VEGF medications had comparable systemic safety profiles in our study. Both drugs represent efficacious and safe therapies for ocular diseases.

Abstract
BACKGROUND To explore image processing methods for optical coherence tomography angiography (OCTA) of the epiretinal membrane (ERM), and to evaluate the impact of ERM on vision by analyzing the retinal vasculature. METHODS Thirty eyes of 30 patients with idiopathic ERM who underwent OCTA were retrospectively evaluated. Image processing of OCTA, including the Mexican hat filter (MHF) and exclusion of the foveal avascular zone (FAZ), was attempted using Fiji. OCTA parameters, including vessel density (VD), fractal dimension (FD), and vessel tortuosity (VT), were measured for large vessels only, capillaries only, and the whole vasculature. Pearson correlation analysis was used to evaluate the correlations between best-corrected visual acuity (BCVA) and OCTA parameters. RESULTS The correlations between BCVA and retinal vasculature were much increased when the capillaries only instead of the whole vasculature was used for analysis. Both higher VD and FD of capillaries were correlated with better BCVA, and MHF largely increased their correlations (P < 0.0001 for both). In contrast, both higher VD and FD of the large vessels were associated with poorer BCVA (P = 0.042 and 0.049, respectively). A higher VT of capillaries was correlated with better BCVA, and both MHF and exclusion of the FAZ were necessary to reveal their correlations (P = 0.028) CONCLUSIONS: Separation of large vessels and capillaries was necessary to reveal the correlation between retinal vasculature and BCVA in ERM. MHF was necessary to elucidate all microvascular parameters of capillaries, and exclusion of the FAZ was mandatory for evaluation of VT.

Abstract
BACKGROUND To elucidate the pattern of the choroidal vasculature in exudative pachychoroid neovasculopathy (PNV) and its correlation with the clinical course and treatment outcomes. METHODS The retrospective study included consecutive patients in National Taiwan University Hospital between 2014 and 2020 who fulfilled the criteria for exudative PNV defined as active type 1 macular neovascularization (MNV) on optical coherence tomography angiography (OCTA) and with leakage on fluorescein angiography (FA) or indocyanine green angiography (ICGA) associated with pachychoroid features. The corrected distance visual acuity (CDVA), FA, ICGA, and OCT images obtained by Optovue (Optovue Inc, Freemont CA, USA) spectral domain OCT were evaluated at baseline and various time points during the 12-month treatment period. The correlations between the choroidal vascular patterns, specifically those with or without dilated choroidal vascular channels (DCVC) revealed by ICGA, and baseline characteristics and treatment outcomes were evaluated using multiple regression models. RESULTS The study enrolled 34 eyes of 31 patients. The average age was 59.0 ± 9.3 years, and 20 participants were men. ICGA revealed DCVCs in 21 eyes, while the remaining 13 eyes did not have DCVCs. At baseline, DCVC group was older (p = 0.03) and had a longer duration of visual symptoms (p = 0.02), with a higher vessel density (defined as the percentage of the measured area occupied by flow area) of MNV (p = 0.04), higher proportion of ellipsoid zone disruption (p = 0.01), and poorer CDVA (p = 0.03). After the 12-month treatment period, the frequency of requirement of anti-VEGF injections (p < 0.01) was higher, and the risk for CDVA <20/40 was higher (adjusted OR: 5.29, 95% CI: 1.24-22.48, p = 0.02) in eyes with DCVCs. CONCLUSIONS For PNV, eyes with DCVCs were associated with higher vessel density of macular neovascularization and poorer CDVA at baseline, and had poorer visual and anatomical outcomes although more anti-VEGF injections were given.

Abstract
PURPOSE The aim was to develop a deep learning model for predicting the extent of visual impairment in epiretinal membrane (ERM) using optical coherence tomography (OCT) images, and to analyze the associated features. METHODS Six hundred macular OCT images from eyes with ERM and no visually significant media opacity or other retinal diseases were obtained. Those with best-corrected visual acuity ≤20/50 were classified as "profound visual impairment," while those with best-corrected visual acuity >20/50 were classified as "less visual impairment." Ninety percent of images were used as the training data set and 10% were used for testing. Two convolutional neural network models (ResNet-50 and ResNet-18) were adopted for training. The t-distributed stochastic neighbor-embedding approach was used to compare their performances. The Grad-CAM technique was used in the heat map generative phase for feature analysis. RESULTS During the model development, the training accuracy was 100% in both convolutional neural network models, while the testing accuracy was 70% and 80% for ResNet-18 and ResNet-50, respectively. The t-distributed stochastic neighbor-embedding approach found that the deeper structure (ResNet-50) had better discrimination on OCT characteristics for visual impairment than the shallower structure (ResNet-18). The heat maps indicated that the key features for visual impairment were located mostly in the inner retinal layers of the fovea and parafoveal regions. CONCLUSIONS Deep learning algorithms could assess the extent of visual impairment from OCT images in patients with ERM. Changes in inner retinal layers were found to have a greater impact on visual acuity than the outer retinal changes.

Abstract
PURPOSE To explore the clinical features and outcomes of cytomegalovirus retinitis (CMVR) in patients with HIV and non-HIV. METHODS This retrospective cohort study included all patients with CMVR in National Taiwan University Hospital from 2013 to 2018. Demographic data, clinical characteristics, CMVR recurrence, and overall survival were compared between the HIV and non-HIV groups. Generalized estimating equation models were implemented to analyze the risk factors of poor visual prognosis. The Kaplan-Meier survival analysis was performed to investigate recurrence and survival. RESULTS A total of 66 patients (95 eyes) with CMVR were enrolled, with no significant differences between the HIV (41 patients; 61 eyes) and non-HIV (25 patients; 34 eyes) groups in initial/final visual acuity, lesion area, or viral loads. Poor visual outcome was associated with poor initial visual acuity, retinal detachment, and a higher plasma cytomegalovirus titer. The HIV group had significantly longer survival rate ( P = 0.033) and lower recurrence rate ( P = 0.01) than the non-HIV group, and it also presented with better prognosis in recurrence-free survival analysis ( P = 0.01). CONCLUSION Patients with CMVR without HIV had higher mortality and recurrence rates than the HIV group. Risk factors of poor visual outcome included poor initial visual acuity, retinal detachment, and a high plasma cytomegalovirus titer.

Abstract
Purpose: Hydroxychloroquine (HCQ) would cause irreversible retinal damage, despite its pivotal role in treatment of systemic lupus erythematosus (SLE). This study aims to reassess the characteristics and risk factors of HCQ retinopathy. Methods: This study included patients with SLE who had used HCQ for >5 years and received ophthalmologic examinations during November 2017 to December 2020 in a tertiary hospital in Taiwan. Spectral-domain optical coherence tomography (SD-OCT) and fundus autofluorescence (FAF) were performed in all patients. Visual field assessment and/or multifocal electroretinography were done if suspicious findings were noted by SD-OCT or FAF. Clinical features and dosing details of HCQ were recorded by chart review. Results: Ninety-two patients were included, with the median duration of drug exposure of 11.2 years [interquartile range (IQR) 9.4-12.7 years], median daily dose of 6.9 mg/kg (IQR 6.1-7.7 mg/kg), and cumulative dose of 1,503.6 g (IQR 1,257.7-1,805.9 g). HCQ retinopathy was diagnosed in 10.9% of patients (10 of 92), and in 20.8% of patients (5 of 24) who complained about blurred vision. High myopia [odds ratio (OR) 5.03; 95% confidence interval (CI) 1.29-24.79; P = 0.03] and lower body weight (OR 0.88; 95% CI 0.78-0.97; P = 0.03) were significantly associated with HCQ retinopathy. Conclusions: Long-term HCQ users may suffer from retinal toxicity. Since there is no optimal substitute for HCQ, careful retinal evaluation is needed to avoid unnecessary drug discontinuation. In addition, an association between high myopia and HCQ retinopathy was noted. More investigation is needed to clarify this association.

Abstract
Background To identify the predictive parameter among preoperative measurements that best predicts postoperative visual outcome in the epiretinal membrane (ERM). Methods Thirty-three consecutive patients with idiopathic unilateral ERM patients between 2015 and 2018 were enrolled. Nineteen healthy normal eyes were selected as an independent age-matched group. Based on preoperative optical coherence tomography (OCT), we further divided the patients with ERM into two groups: type 1, loosely attached ERM, and type 2, tight adherent ERM. We documented the vision and thickness of various retinal layers: nerve fiber layer, ganglion cell layer, inner plexiform layer (GCL + IPL), inner nuclear layer (INL), outer retinal layer (ORL), and retinal pigment epithelium/Bruch complex layer before and after the surgery. The association between postoperative visual acuity and these variables was analyzed using multiple linear regression analysis. Results All retinal layers of ERM eyes were thicker than the normal eyes (P < 0.05). Among ERMs, we identified 11 eyes with type 1 adhesions and 22 eyes with type 2 adhesions. The preoperative GCL + IPL layers were significantly thicker in type 2 patients than in type 1 patients (93.67 ± 33.03 um vs 167.71 ± 13.77 um; P = 0.023). Greater GCL + IPL thickness was correlated with a worse postoperative visual acuity and multiple linear regression analysis showed that GCL + IPL thickness was an independent predictor of postoperative visual acuity (VA) (beta value = 0.689; P = 0.012). A greater thickness of GCL + IPL layers of type 2 patients had worse postoperative best-corrected visual acuity (BCVA) (P = 0.028). Ectopic inner foveal layers with disappearance of fovea pit were persistently presented in OCT profiles of both groups. Conclusion Idiopathic ERM demonstrated significantly thicker inner retinal layers (GCL + IPL and INL). However, the ORL thickness was similar between the normal eyes and ERM eyes. The preoperative GCL + IPL layers were significantly thicker in patients with type 2 ERM than that in patients with type 1 ERM. The increase in GCL + IPL thickness was significantly correlated with worse postoperative visual outcomes.

Abstract
A green method for synthesizing Pd nanoparticles/graphene composites from a choline chloride-oxalic acid deep eutectic solvent (DES) without a reducing agent or a surfactant is reported. Deep eutectic solvents are usually composed of halide salts and hydrogen-bond donors, and many are biocompatible and biodegradable. The merits of deep eutectic solvents include that they serve as reducing agents and dispersants, and Pd nanoparticles are tightly anchored to graphene. The size and dispersion of Pd particles are improved when supercritical carbon dioxide (scCO2) is used because it has gaslike diffusivity and near-zero surface tension, which results in excellent wettability between the scCO2 and the carbon surface. The prepared sc-Pd NPs/GR/SPCE shows excellent activity toward glycerol oxidation compared to composites not fabricated by scCO2 processes. This study demonstrates the potential of using this scCO2-assisted protocol combined with deep eutectic solvents to further construct nanoparticles/graphene composites.

Abstract
The photoactivity of nanoporous bismuth vanadate (BiVO4, BVO) photoanodes that were fabricated by a two-step process (electrodeposition and then thermal conversion) in photoelectrochemical (PEC) hydrogen (H2) evolution can be enhanced about 1.44-fold by improving the constitutive ratio of (111̅), (061), and (242̅) crystal facets. The PEC characterization was carried out to investigate the factors altering the performance, which revealed that the crystal facet modulation could improve the photoactivity of the BVO photoanodes. In addition, the orientation-controlled BVO thin-film electrodes are introduced as evidence that the present crystal facet modulation is the positive effect for BVO photoanodes in PEC. The investigation of energy band structures and interfacial charge carrier dynamics of the BVO photoanodes reveals that the crystal facet modulation could result in a shorter lifetime of charge carrier recombination and larger band bending at the interface between BVO and electrolytes. This outcome could improve the charge separation and charge transfer efficiencies of BVO photoanodes, promoting the efficiency of PEC H2 evolution. Moreover, this crystal facet modulation can combine with co-catalyst decoration to further improve the solar-to-hydrogen efficiency of BVO photoanodes in PEC. This study presents a potential strategy to promote the PEC activity by crystal facet modulation and important insights into the interfacial charge transfer properties of semiconductor photoelectrodes for the application in solar fuel generation.

Abstract
To investigate optical coherence tomography (OCT) and OCT angiography (OCTA) biomarkers for good visual outcomes in eyes with myopic choroidal neovascularization (mCNV) following anti-vascular endothelial growth factor (anti-VEGF) therapy. Patients diagnosed with mCNV via multimodal imaging were retrospectively reviewed. Baseline demographic data and biomarkers were collected. Anti-VEGF treatment based on a pro re nata (PRN) regimen was conducted on all eyes. The visual gains of ≥ 15 ETDRS letters or < 15 letters at 12-month were classified into two groups. Regression analysis was used to identify variables associated with significant best-corrected visual acuity (BCVA) improvement. Among 34 patients, 17 eyes and 17 eyes were classified into the two groups. There were no statistically significant differences in qualitative OCTA biomarkers between the two groups. The ≥ 15 letters group had significantly thicker subfoveal choroid thickness (SFCT) (79.97 ± 33.15 vs. 50.66 ± 18.31, P = 0.003), more ellipsoid zone integrity (58.8% vs. 23.5%, P = 0.037) and lower levels of fractal dimension (1.45 ± 0.101 vs. 1.53 ± 0.082, P = 0.031) than the < 15 letters group. SFCT and the ellipsoid zone integrity were correlated with 15 letters or more VA improvement in both univariable and multivariable analyses (P = 0.023 and P = 0.044, respectively). Thicker SFCT and integrity of the ellipsoid zone at baseline were associated with greater visual gains at 12 months. OCTA biomarkers seem to play a less important role in predicting the visual outcome of mCNV.

Abstract
Emotion recognition deficit is related to impaired community functioning. Loneliness is also associated with impaired social performance. However, the way in which emotion recognition and loneliness may contribute to social functioning remains unclear in euthymic patients with bipolar disorder. We aimed to examine emotion recognition ability in Han Chinese euBD patients relative to healthy controls (HCs) and to investigate the associations between emotion recognition, loneliness, and social functioning. Thirty-nine HCs and 46 euthymic BD patients completed an emotion recognition task and nonsocial cognitive measures related to executive function and attention. The UCLA loneliness scale and Social Performance Scale were administered to evaluate psychological loneliness and social functioning, respectively. We observed lower emotion recognition accuracy, higher loneliness, and poorer social functioning in the BD patients after adjustment for demographic data. Loneliness was negatively associated with global social functioning in both the BD and HC groups. Higher loneliness and lower emotion recognition accuracy were associated with poorer social functioning in euthymic BD in different subdomains. Our study confirmed a subtle impairment of emotion recognition ability in euthymic BD. Loneliness impacts globally on social functioning, while emotion recognition ability may affect specific subdomains of social functioning in euthymic BD. Alleviation of loneliness and enhancement of social cognition might improve social functioning in BD patients.

Abstract
Background We investigated whether antiplatelet/anticoagulant (APAC) therapy can protect patients with type 2 diabetes mellitus (T2DM) from the development or progression of diabetic retinopathy (DR). Methods This is a retrospective cohort study using Longitudinal Health Insurance Database in Taiwan. A total of 73,964 type 2 diabetic patients older than 20 years old were included. Hazard ration (HR) of non-proliferative DR (NPDR), proliferative DR (PDR), and diabetic macular edema (DME) were analyzed with APAC usage as a time-dependent covariate. Age, sex, comorbidities, and medicines were further adjusted in a multi-variable model. Contributions of respective APAC was investigated with sensitivity analysis. Results Compared with nonusers, APAC users had a lower cumulative incidence of NPDR (P < 0.001), overall incidence of NPDR (10.7 per 1000 person-years), and risk of developing NPDR (adjusted HR = 0.78, 95% CI = 0.73–0.83). However, no significant differences were observed between APAC users and nonusers in the risks of PDR or DME. Hypertension, diabetic nephropathy and diabetic neuropathy were risk factors for NDPR development, while heart disease, cardiovascular disease, peripheral arterial occlusive disease, and statin usage were covariates decreasing NPDR development. Aspirin and Dipyridamole showed significant protection against NPDR development. Clopidogrel, Ticlopidine, and warfarin showed enhanced protection in combination with aspirin usage. Conclusions APAC medications have a protective effect against NPDR development. Diabetic patients benefit from single use of aspirin or dipyridamole on prevention of NPDR.

Abstract
PURPOSE To develop deep learning models for identification of sex and age from macular optical coherence tomography (OCT) and to analyze the features for differentiation of sex and age. DESIGN Algorithm development using database of macular OCT. METHODS We reviewed 6147 sets of macular OCT images from the healthy eyes of 3134 individuals from a single eye center in Taiwan. Deep learning-based algorithms were used to develop models for the identification of sex and age, and 10-fold cross-validation was applied. Gradient-weighted class activation mapping was used for feature analysis. RESULTS The accuracy for sex prediction using deep learning from macular OCT was 85.6% ± 2.1% compared with accuracy of 61.9% using macular thickness and 61.4% ± 4.0% using deep learning from infrared fundus photography (P < .001 for both). The mean absolute error for age prediction using deep learning from macular OCT was 5.78 ± 0.29 years. A thorough analysis of the prediction accuracy and the gradient-weighted class activation mapping showed that the cross-sectional foveal contour lead to a better sex distinction than macular thickness or fundus photography, and the age-related characteristics of macula were on the whole layers of retina rather than the choroid. CONCLUSIONS Sex and age could be identified from macular OCT using deep learning with good accuracy. The main sexual difference of macula lies in the foveal contour, and the whole layers of retina differ with aging. These novel findings provide useful information for further investigation in the pathogenesis of sex- and age-related macular structural diseases.

Abstract
Purpose To measure the anatomical characteristics of the macula in fellow eyes of patients with unilateral idiopathic epiretinal membrane (ERM) and to compare them with normal controls. Methods A total of 83 fellow eyes with unilateral idiopathic ERM were gathered as the study group, and their age- and sex-matched subjects with no vitreomacular diseases were recruited as the control group. Macular structure parameters including foveal base width (FBW), central foveolar thickness (CFT), central subfield thickness (CST), area of foveal avascular zone (FAZ), and retinal artery trajectory (RAT) were measured using optical coherence tomography (OCT) and OCT angiography and were compared between two groups. Results For the study group, the FBW (463.8 ± 79.6 µm) and area of FAZ (0.39 ± 0.12 mm2) were significantly larger than those in the control group (334.3 ± 76.5 µm, 0.31 ± 0.13 mm2). Their CST was thinner and their RAT was wider than those of the control group (P < 0.05 for all). In the normal population, females had a wider FBW, a thinner CFT, and a wider RAT than males (P < 0.05 for all). Conclusions Fellow eyes of the unilateral ERM had a larger FBW, a larger FAZ, a thinner CST, and a wider RAT than the normal population. This implicates that some centrifugal tractional force may exist on their macula, which eventually may result in the formation of idiopathic ERM. Females had a wider FBW, a thinner CFT, and a wider RAT than males, which may explain the higher prevalence of idiopathic ERM in females.

Abstract
Purpose To compare 2-year treatment outcomes of ranibizumab using treat-and-extend (T&E) or pro re nata (PRN) regimens for diabetic macular edema (DME) in clinical settings. Methods We retrospectively enrolled 34 patients (34 eyes) with DME treated with ranibizumab using the T&E regimen, and 34 patients (34 eyes) treated with ranibizumab using the PRN regimen and matched to cases in the treat-and-extend group by baseline best-corrected visual acuity (BCVA) and central foveal thickness (CFT). BCVA and CFT changes, number of injections and recurrence of macular edema over 2 years were compared between the groups. Results The average BCVA gain in the T&E and PRN groups was 16.2 and 7.6 ETDRS letters at 2 years (p = 0.011), respectively. The mean CFT reduction was 145.5 ± 127.3 and 97.3 ± 152.5 μm in the T&E and PRN groups at 2 years (p = 0.035), respectively. The T&E group had a higher proportion of patients with BCVA gain ≥ 15 letters at months 18 (p = 0.015) and 24 (p = 0.029) than the PRN group. During the 2-year treatment periods, the T&E group received more injections than the PRN group (11.0 ± 3.2 vs. 6.2 ± 2.0; p < 0.001), while the PRN group had more recurrence of macular edema than the T&E group (71 vs. 41%; p = 0.015). Conclusions After 2-year ranibizumab treatment for DME, better visual and anatomical improvement and less recurrence of macular edema were achieved in the T&E group, with more injections administered.

Abstract
PURPOSE To assess ocular involvement in sarcoidosis and to analyze the manifestations of ocular sarcoidosis (OS) in Taiwan. METHODS A retrospective review was performed in 364 patients diagnosed as sarcoidosis at National Taiwan University Hospital from 2015 to 2019. The OS diagnosis was based on the revised criteria of International Workshop on Ocular Sarcoidosis. Demographics, clinical manifestations, treatment and effects, complications, visual outcomes and risk factors of poor vision (<20/200) were analyzed. RESULTS A total of 122 eyes of 66 patients (13 males and 53 females) with OS were identified. Bilateral involvement accounted for 84.8%. Thirty-five patients were diagnosed with definite OS, 14 with presumed OS and 17 with probable OS. The average age was 51.9 ± 14.1 years, with no significant difference in sex. Most patients presented with panuveitis (61 eyes, 50.0%) and posterior uveitis (52 eyes, 42.6%). Systemic steroid was the mainstay treatment, and immunosuppressants or anti-metabolic agents were supplemented. Common complications included cataract (50.8%), ocular hypertension/glaucoma (25.4%) and posterior synechiae (20.5%). Forty-three eyes (36.1%) and 74 eyes (62.2%) had a final vision of 20/20 and 20/40 or better, respectively. The causes of poor visual outcome were diverse, and generalized estimating equations analysis indicated that female and poor initial vision were risk factors. CONCLUSION Uveitis is an early sign of sarcoidosis and it might result in several complications. The overall visual outcomes were good if patients received proper treatment. Both poor initial vision and females that tended to have more severe complications were associated with poor outcome.

Abstract
PURPOSE To investigate the clinical features and treatment outcomes of idiopathic full thickness macular hole (FTMH) without vitreomacular separation (VMS). METHODS Consecutive cases of idiopathic FTMH at one tertiary center from January 2013 to April 2020 was retrospectively recruited. They were separated into two groups according to the findings in optical coherence tomography (OCT): FTMH with VMS and FTMH without VMS. Ophthalmic examinations and OCT were performed pre and postoperatively. The clinical findings were compared between two groups. RESULTS Of the total 124 cases, 15 (12.1 %) were noted as FTMH without VMS with the presence of an attached posterior hyaloid (PH) at macula. The macular hole (MH) size was smaller (276.06 ± 170.10 µm) compared to those with VMS (492.83 ± 209.31 µm) (P < 0.001). The incidence of lamellar hole associated epiretinal proliferation (LHEP) was much higher in this group (13/15, 86.7%), compared to FTMH with VMS (11/109, 10.1%) (P < 0.001). A higher rate of spontaneous closure of MH (13.3%) was also noted in FMTH without VMS (13.3% vs 0.9% in FTMH with VMS, P = 0.040). After operation, the MH closure rate was 93.3%. The postoperative best-corrected visual acuity was not significantly different between two groups (P = 0.098). CONCLUSIONS A small percentage (12.1% in this series) of idiopathic FTMH had no VMS. The completely attached PH along with the high incidence of LHEP implied a tangential traction in FTMH without VMS. The MH size was usually small, and the postoperative outcomes was similar to those of conventional FTMH with VMS.

Abstract
AIMS To investigate the applicability of deep learning image assessment software VeriSee DR to different color fundus cameras for the screening of diabetic retinopathy (DR). METHODS Color fundus images of diabetes patients taken with three different nonmydriatic fundus cameras, including 477 Topcon TRC-NW400, 459 Topcon TRC-NW8 series, and 471 Kowa nonmyd 8 series that were judged as "gradable" by one ophthalmologist were enrolled for validation. VeriSee DR was then used for the diagnosis of referable DR according to the International Clinical Diabetic Retinopathy Disease Severity Scale. Gradability, sensitivity, and specificity were calculated for each camera model. RESULTS All images (100%) from the three camera models were gradable for VeriSee DR. The sensitivity for diagnosing referable DR in the TRC-NW400, TRC-NW8, and non-myd 8 series was 89.3%, 94.6%, and 95.7%, respectively, while the specificity was 94.2%, 90.4%, and 89.3%, respectively. Neither the sensitivity nor the specificity differed significantly between these camera models and the original camera model used for VeriSee DR development (p = 0.40, p = 0.065, respectively). CONCLUSIONS VeriSee DR was applicable to a variety of color fundus cameras with 100% agreement with ophthalmologists in terms of gradability and good sensitivity and specificity for the diagnosis of referable DR.

Abstract
Neovascular age-related macular degeneration (nAMD) is a leading cause of irreversible vision loss. The present consensus provides suggestions on diagnosis, evaluation, treatment, and follow-up strategies for nAMD from a panel of 11 practicing ophthalmologists. The experts suggest that the baseline visit for nAMD management should include a comprehensive ophthalmologic examination via a multimodal approach consisting of visual and anatomical evaluation. Patients diagnosed with nAMD should be subjected to treatment with the goal of maintaining visual function while diminishing anatomical disease activity and minimizing treatment burden. Currently, anti-VEGF therapy is the main treatment strategy for nAMD, and evaluation involving comprehensive ophthalmologic examination within 1 month of completion of the loading phase comprising three monthly injections is recommended to guide subsequent management. Either a treat-and-extend or pro re nata regimen can be considered for the maintenance phase of anti-VEGF therapy, and the regimen should be chosen and adjusted according to disease activity, reimbursement criteria, financial burden, and patient preferences. In the event of inactive nAMD or poor treatment outcomes, after thorough evaluation and patient education, anti-VEGF therapy may be stopped. The consensus provides practical nAMD management guidelines for ophthalmologists and fellow healthcare professionals.

Abstract
Background: Sjogren's syndrome (SS) is a chronic inflammatory autoimmune disease mainly characterized by dryness, fatigue, and pain. Current therapies for SS in Western medicine are limited. The purpose of this clinical study was to explore the efficacy and safety of using a traditional Chinese medicine (TCM) formula on patients with primary SS. Methods: We performed a 12-week, randomized, double-blinded, placebo-controlled clinical trial at Chung Shan Medical University Hospital. We included 42 patients with SS between the ages of 20 and 80 years who met the classification criteria of the American and European Consensus Group (AECG). Patients who had other severe systemic manifestations or diseases were excluded from this trial. After screening, patients were randomly assigned to the TCM treatment group or placebo group (ratio of 2:1). We treated the TCM group with 6 g of Gan-Lu-Yin granules after breakfast and 6 g of Jia-Wei-Xiao-Yao-San combined with 1 g of Suan-Zao-Ren-Tang and 1 g of Ye-Jiao-Teng every night after dinner. Patients in the control group were treated with a placebo with the same appearance and flavor but only one-tenth the dosage of that received by the treatment group. The European League Against Rheumatism Sjogren's Syndrome Patient-Reported Index (ESSPRI) was used as the primary endpoint at week 12. Secondary endpoints were the Sjogren's Syndrome Disease Activity Index (SSDAI), physician global assessment (PGA), visual analogue scale (VAS), Multidimensional Fatigue Inventory, Medical Outcomes Survey Short Form-36, and the Pittsburgh Sleep Quality Score (PSQI). Adverse events were also recorded. Results: Of the 42 randomized patients, 28 patients were assigned to the TCM treatment group and 14 patients were assigned to the controlled group. During the study period, 5 patients withdrew from the TCM group and 7 withdrew from the control group. At week 12, the ESSPRI scores of both groups had improved. The ESSPRI score of the treatment group decreased by 0.62 (95% CI P = 0.557) and that of the placebo group decreased by 0.91 (P = 0.557). However, no significant difference was observed between the two groups. Sleep duration in the PSQI was -0.61, which exhibited an improvement of more than the -0.21 compared with the placebo group (P = 0.914). Conclusion: At week 12, the ESSPRI scores did not reveal that the use of the TCM formula was efficacious for treating patients with Sjogren's syndrome. However, the PSQI scores indicated that this formula could prolong patient sleep duration. We also found that this formula could decrease the blood pressure of patients.

Abstract
Electroretinography (ERG) is an important and well-established examination for retinal and visual pathway diseases. This study reviewed the medical records of patients who received full-field ERG (ffERG) at a single medical center between 2012 and 2019, which was an 8-year experience in the clinical contribution of ERG. Based on the indication for scheduling ffERG and the final diagnosis, patients could be classified into six groups: ‘retinal dystrophies’, ‘other retinal or macular diseases’, ‘optic neuropathies’, ‘visual complaints’, ‘systemic diseases’, and ‘others’. A total of 1921 full-field electroretinograms (ffERGs) (1655 patients) were included. The average number of ffERGs performed per year was 262 and the number of annual ffERGs was constant. The ‘retinal dystrophies’ group accounted for 36.5% of the studied population, followed by the ‘other retinal or macular diseases’ group (20.2%). The most common systemic disease was central nervous system disease. The rates of abnormal ffERGs in the ‘systemic diseases’, ‘optic neuropathies’, and ‘visual complaints’ groups were 27.3%, 22.6%, and 10.1%, respectively (p < 0.001). Higher rates were found in patients <20 years old in the ‘systemic diseases’ and ‘optic neuropathies’ groups; epilepsy and optic nerve atrophy were the most common diagnoses, respectively. In brief, by quantifying the functional response in the retina, ffERG is indispensable for diagnosis and prognosis in ophthalmologic and multidisciplinary practice.

Abstract
Background: Inappropriate and excessive use of gadgets can cause addiction and interfere with physical, psychological, and emotional health, increase social isolation, and negatively affect development, especially in children. The resulting impact will be greatly influenced by the role of parents, family and the environment. Purpose: This study aims to understand what education can be provided to parents of children with gadget addiction, along with how parents can choose toys and alternative games for children to reduce this gadget addiction. Methods: The design used in this article was a narrative review that involved collecting and analyzing journals using the keywords "addiction", "children", "education", "parent" and "gadget"; this obtained 10 journal articles from PubMed, two journal articles from ScienceDirect, 14 journal articles from Google Scholar published between 2015–2020, three books, and one collection of survey data from the web. Results: There were several strategies that could be applied in managing the use of gadgets by children. The authoritative type of parenting style, good parent-child relationships, parent-child attachment and family environment conditions could also affect the use of gadgets and its impact on children. Parents could additionally provide toys and alternative games suitable for the children’s age, developmental ability and safety needs. Conclusion: Parents are expected to understand how to manage children with gadget addiction and how they can choose toys and alternative games for children to reduce gadget addiction.

Abstract
This study aimed to evaluate the reliability of in vivo confocal microscopic neuroanalysis by beginners using manual and automated modules. Images of sub-basal corneal nerve plexus (SCNP) from 108 images of 18 healthy participants were analyzed by 7 beginner observers using manual (CCMetrics, [CCM]) and automated (ACCMetrics, [ACCM]) module. SCNP parameters analyzed included corneal nerve fiber density (NFD), corneal nerve branch density (NBD), corneal nerve fiber length (NFL), and tortuosity coefficient (TC). The intra-observer repeatability, inter-observer reliability, inter-module agreement, and left–right eye symmetry level of SCNP parameters were examined. All observers showed good intra-observer repeatability using CCM (intraclass correlation coefficient [ICC] > 0.60 for all), except when measuring TC. Two observers demonstrated especially excellent repeatability in analyzing NFD, NBD, and NFL using manual mode, indicating the quality of interpretation may still be observer-dependent. Among all SCNP parameters, NFL had the best inter-observer reliability (Spearman’s rank-sum correlation coefficient [SpCC] and ICC > 0.85 for the 3 original observers) and left–right symmetry level (SpCC and ICC > 0.60). In the additional analysis of inter-observer reliability using results by all 7 observers, only NFL showed good inter-observer reliability (ICC = 0.79). Compared with CCM measurements, values of ACCM measurements were significantly lower, implying a poor inter-module agreement. Our result suggested that performance of quantitative corneal neuroanalysis by beginners maybe acceptable, with NFL being the most reliable parameter, and automated method cannot fully replace manual work.

Abstract
To investigate choroidal neovascularization (CNV) characteristics after anti-vascular endothelial growth factor (anti-VEGF) therapy in patients with neovascular age-related macular degeneration by optical coherence tomography angiography (OCTA) and to assess the potential predictive role of combined qualitative and quantitative biomarkers for disease activity. Patients diagnosed with type 1 or type 2 CNV via multimodal imaging who had received anti-VEGF treatment were retrospectively reviewed. Qualitative and quantitative CNV responses on OCTA after serial injections were analyzed. The enrolled eyes were divided into two groups based on treatment intervals during follow-up, including an active group with less than 12 weeks intervals and a stable group with 12 weeks or longer intervals. Fifty-six eyes of 56 patients were included in the study. Twenty-seven eyes (48.2%) were classified as the “active group”, and 29 eyes (51.8%) were categorized as the “silent group”. Qualitative biomarkers of CNV showed significant differences between the two groups (branching capillaries: 48.1% vs 6.9%, p = 0.001; anastomoses and loops: 81.5% vs 13.8%, p < 0.001; peripheral arcade: 40.7% vs 10.3%, p = 0.013, and hypointense halo: 81.5% vs 41.4%, p = 0.002). A significantly higher vessel density was found in the active group (median 39.6% vs 30.5%, p = 0.003). “Anastomoses and loops” and “vessel density” predicted an active CNV status with a probability of 93.7% and achieved the best performance. The combination of two potential biomarkers of CNV on OCTA shows good discrimination for the prediction of recurrent exudation auxiliary to structural OCT that might associate with disease activity.

Abstract
This study highlights the clinical features and treatment response of polypoidal choroidal vasculopathy (PCV) among three different branching vascular network (BVN) morphologies in optical coherence tomography angiography (OCTA), and further correlates the BVN features with those under fluorescent angiography (FA) and indocyanine green angiography (ICGA). In total, we reviewed 70 eyes with PCV followed up for > 12 months. OCTA, ICGA and FA images were obtained at baseline and post-treatments. BVN was assessed using OCTA and divided into three types by a previously described BVN classification: type 1 (trunk), type 2 (glomeruli), and type 3 (stick). At baseline, type 1 BVN had the poorest vision and thinnest subfoveal choroidal thickness (SFCT), whereas type 3 had the best vision and thickest SFCT. The aforementioned trend sustained after treatments. Each BVN morphology in OCTA showed typical features in FA + ICGA and encompassed significant correlation (p = 0.004). In conclusion, OCTA is an innovative imaging tool for the detection and classification of BVN in PCV. Furthermore, OCTA has advantages of being noninvasive and free of systemic toxicities. The BVN can be divided into three types based on morphological characteristics in OCTA, which play crucial roles in clinical presentations and treatment outcomes.

Abstract
The electrochemical sensing applications of a series of water-stable 2D metal–organic framework (MOF)-modified screen-printed carbon electrodes (SPCEs) are reported. The MOF materials in this study are [M(bipy)(C4O4)(H2O)2]·3H2O, in which bipy = 4,4′-bipyridine and M = Mn, Fe, Co and Zn. The MOF materials are characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), showing that the MOFs have a layer-by-layer rod structure with a smooth surface. We use the nitrofurazone molecule as a probe to investigate the influence of the metal ions of MOFs on electrochemical sensing ability. Cyclic voltammetry demonstrated that the Mn-MOF electrode of interest delivered stronger signals than that of other electrodes. Through first-principles calculations, we also revealed that the change in the spin polarization of divalent metal ions passing from the free ion state to the MOF environment appeared to be significantly correlated with the enhancement in the peak response current. The theoretical and experimental results consistently indicate that Mn-MOF has the smallest bandgap and good sensitivity among these MOF materials. Accordingly, we proposed a simple model to illustrate this observation and disclosed the importance of the electron configuration of the transition metal constructing the MOF materials used in improving electrochemical sensing applications. Framework-to-metal charge transfer of the MOF materials results in enhancing electrochemical sensing ability to nitrofurazone.![]()
