Predicting central choroidal thickness from colour fundus photographs using deep learning.

The estimation of central choroidal thickness from colour fundus images can improve disease detection. We developed a deep learning method to estimate central choroidal thickness from colour fundus images at a single institution, using independent datasets from other institutions for validation. A total of 2,548 images from patients who underwent same-day optical coherence tomography examination and colour fundus imaging at the outpatient clinic of Jichi Medical University Hospital were retrospectively analysed. For validation, 393 images from three institutions were used. Patients with signs of subretinal haemorrhage, central serous detachment, retinal pigment epithelial detachment, and/or macular oedema were excluded. All other fundus photographs with a visible pigment epithelium were included. The main outcome measure was the standard deviation of 10-fold cross-validation. Validation was performed using the original algorithm and the algorithm after learning based on images from all institutions. The standard deviation of 10-fold cross-validation was 73 µm. The standard deviation for other institutions was reduced by re-learning. We describe the first application and validation of a deep learning approach for the estimation of central choroidal thickness from fundus images. This algorithm is expected to help graders judge choroidal thickening and thinning.

Parasomnia induced by lemborexant: a case report.

Lemborexant, an orexin receptor antagonist, is effective not only for sleep disorders but also for preventing and treating delirium. To date, no complex sleep-related behaviors due to lemborexant have been reported. Herein, we present the case of a 69-year-old male patient who was hospitalized for oral floor and tongue cancer and developed delirium after surgery; however, upon lemborexant dosage increase, used to treat insomnia, he developed abnormal nocturnal behavior. This symptom rapidly improved when lemborexant was discontinued. Distinguishing parasomnia from delirium is important because the treatment of these two conditions differs. Although rapid eye movement sleep behavior or sleepwalking was the cause of this parasomnia, a definitive diagnosis could not be established. If qualitatively distinct abnormal behavior is observed compared to delirium after increasing lemborexant dosage, the possibility of parasomnia should be considered.

Scleritis following intravitreal brolucizumab injection: a case series.

BACKGROUND: This study reports the first cases of scleritis following intravitreal brolucizumab (IVBr) injection for nAMD, emphasizing the need to be aware of the possibility of scleritis following IVBr injections. CASE PRESENTATION: Case 1. A 74-year-old Japanese man with nAMD complained of conjunctivitis and decreased vision in the right eye 8 days after his eighth IVBr injection. Examination revealed scleritis without anterior inflammation. Topical 0.1% betamethasone and 0.3% gatifloxacin eye drops were started. The scleritis worsened in the following 2 weeks and became painful. He underwent sub-Tenon's capsule triamcinolone acetonide (STTA) injection. Two days later, he returned with a complaint of severe vision loss. Fundus examination revealed retinal artery occlusion, vasculitis, and vitreous opacity in the right eye. Vitreous surgery was performed. CASE 2: An 85-year-old Japanese woman with nAMD in the right eye complained of reddening of the eye 27 days after her fifth IVBr injection. Examination showed conjunctivitis and scleritis without anterior inflammation in the right eye. She was started on 0.1% fluorometholone and 0.5% levofloxacin hydrate eye drops. The scleritis worsened in the following 3 weeks. Her treatment was switched to 0.1% betamethasone eye drops. One month later, the scleritis had improved and a sixth IVBr injection was administered. There was no worsening of the scleritis at that time. However, 1 month after a seventh IVBr injection, she complained of severe hyperemia and decreased vision. Fundus examination revealed vitreous opacification. She underwent STTA, and the vitreous opacity improved in 24 days. Case 3. A 57-year-old Japanese man with nAMD complained of pain and decreased vision in the right eye 21 days after a fourth IVBr injection. Examination revealed scleritis with high intraocular pressure but no anterior chamber or fundus inflammation. STTA and topical eye drops were performed. One month later, scleritis improved but visual acuity didn't due to progression of nAMD. CONCLUSIONS: Intraocular inflammation following IVBr injection may progress to the posterior segment. Scleritis can occur after IVBr injection, and topical eye drops alone may not be sufficient for initial treatment. Clinicians should consider the possibility of scleritis in patients with worsening inflammation after IVBr injection.

Association between Children's Difficulties, Parent-Child Sleep, Parental Control, and Children's Screen Time: A Cross-Sectional Study in Japan.

Children's screen time may affect their growth and development. However, differences in the impact of various psychiatric and psychological factors on children's screen time is a research gap. This study aimed to explore the differences in the influence of related factors affecting children's screen time based on their sleep, difficulties, and parental control among Japanese elementary and junior high school students. A cross-sectional survey was conducted among parents in Japan. Data on screen time duration, parent-child background, strengths and difficulties, sleep variables, and parental control types were collected from 225 households. A regression analysis revealed that high Strengths and Difficulties Questionnaire (SDQ) scores (ß = 0.166, p = 0.008), sleep duration (ß = -0.281, p < 0.001), and parental control (ß = -0.204, p = 0.001) were significantly related to children's screen time. Additionally, it was found that parents' late bedtimes affect children's screen time by mediating children's sleep duration. This study, together with previous research, provides comprehensive insights into design interventions to decrease the screen time of children in the Japanese context.

Sodium Valproate Use in Japanese Patients with Schizophrenia and Coronavirus Disease Is Associated with an Increased Risk of Pneumonia.

Schizophrenia is a known risk factor for coronavirus disease (COVID-19) infection and severity, and certain psychotropic drugs have been linked to increased mortality in infected patients with schizophrenia. However, little evidence exists regarding this risk. We retrospectively examined the association between mood stabilizers and the risk of pneumonia in patients with schizophrenia. This study included 99 patients with schizophrenia or schizoaffective disorder who were infected with COVID-19 in 2022 and met the inclusion criteria. After conducting propensity score matching to align patient backgrounds and concomitant medications, we assessed the impact of mood stabilizers, specifically sodium valproate, on the risk of pneumonia development. Univariate analysis revealed that patients with schizophrenia and COVID-19 who developed pneumonia were more likely to be older (64.5 [14.2] vs. 57.4 [11.5] years, p = 0.008) and using sodium valproate (44.4% vs. 16.7%, p = 0.004). Even after propensity score matching, patients who developed pneumonia were still more likely to be receiving sodium valproate than not (58.8% vs. 20.0%, p = 0.003). Sodium valproate use may be a risk factor for the development of pneumonia in patients with chronic schizophrenia who are infected with COVID-19 during long-term hospitalization.

Efficacy of a Modified Treat-and-Extend Aflibercept Regimen for Macular Oedema in Eyes with Central Retinal Vein Occlusion: 2-Year Prospective Study.

This prospective, multicentre, interventional study evaluated the efficacy of a modified treat-and-extend (mTAE) aflibercept regimen as personalized therapy for macular oedema (MO) due to central retinal vein occlusion (CRVO). Fifty eyes were studied from 50 patients who were enrolled between November 2016 and July 2019. All patients received intravitreal aflibercept (IVA) injections on an mTAE regimen for 24 months. Primary outcome measures were best-corrected visual acuity (BCVA) and central subfield thickness (CST) at 12 months. Secondary endpoints were BCVA and CST at 24 months. Mean (standard deviation) baseline BCVA (logMAR) and CST were 0.50 (0.51) and 557 (240) µm, respectively. BCVA and CST showed significant improvements at month 12 (0.19 (0.38) and 275 (98) µm, respectively; both p < 0.0001, paired t-test). BCVA and CST also showed significant improvements at 24 months (0.26 (0.50) and 255 (91) µm, respectively, p = 0.0004 and p < 0.0001, paired t-test). The mean numbers of IVA injections and clinic visits over the 24-month study period were 6.2 (3.0) and 10.3 (1.0), respectively. The mTAE regimen of IVA injections for MO due to CRVO was effective in improving BCVA and decreasing CST at 24 months. The mTAE regimen might be an effective personalized therapy for CRVO.

The vision for public health dietitians' skill improvement over the next 10 years in Japan: A qualitative study.

Objectives: To obtain the basis for developing a new human resource development program. We examined the association between their position type and their vision for skill improvement in the profession in the next 10 years. Study design: This was a qualitative study. Methods: In 2021, we conducted an exhaustive survey of Japanese public health dietitians working in Japanese local governments. Using qualitative content analysis, we analyzed the participants' descriptions of how the profession could improve their skills over the next 10 years. Results: Regardless of the participants' organization of employment or their target position type, seven common categories were extracted; [goals], [health promotion activities], [organizational activities], [evaluation from others], [cooperation], [skills to be acquired], and [means for improving skills]. Depending on the organization type, 35-40 subcategories were extracted from those who wanted to be staff, 35-38 subcategories from those who wanted to be supervisors, and 20-37 subcategories from those who wanted to be managers. Different subcategories were extracted to describe the difference between specialists and generalists in [goals]. Participants described challenges with [evaluation from others] and [collaboration], regardless of the target position type or [goals]. Conclusion: The vision for Japanese public health dietitians' skill improvement to achieve in the next 10 years describes challenges with business evaluation and collaborative work. However, participants differed across what skills they wanted to improve based on the direction of their careers. To offer public health dietitians learning content that connects with their desired direction, a new human resource development program needs to be considered.

Individual Learning Needs of Japanese Public Health Dietitians by Years of Experience in Health Promotion.

Lifelong education for dietitians in Japan is based mainly on competencies according to years of experience. Because learning content differs depending on the desired position and specialty, training programs that reflect the individual learning needs of public health dietitians are needed. This study aimed to assess the individual learning needs of public health dietitians via years of experience in health promotion. In 2021, an online survey of public health dietitians involved in health promotion in prefectures, designated cities, and other municipalities throughout Japan was conducted. Years of experience in health promotion were categorized as early (<10 years), mid-career (10-19 years), and leadership (≥20 years) periods. To ascertain individual learning needs, the survey asked about respondents' desired final position, career path, and skills they felt they needed to improve in the future. Of the 1649 public health dietitians analyzed, all administrative categories preferred to work as public health generalists in mid-career or leadership periods rather than in the early period. In municipalities, more public health dietitians across all experience categories selected "professional competence", such as knowledge in specialized areas and nutritional guidance techniques. It was suggested that public health dietitians in the mid-career and leadership periods have individual learning needs, in both nutrition specialists and public health generalists.

An AI model to estimate visual acuity based solely on cross-sectional OCT imaging of various diseases.

PURPOSE: To develop an artificial intelligence (AI) model for estimating best-corrected visual acuity (BCVA) using horizontal and vertical optical coherence tomography (OCT) scans of various retinal diseases and examine factors associated with its accuracy. METHODS: OCT images and associated BCVA measurements from 2,700 OCT images (accrued from 2004 to 2018 with an Atlantis, Triton; Topcon, Tokyo, Japan) of 756 eyes of 469 patients and their BCVA were retrospectively analysed. For each eye, one horizontal and one vertical OCT scan in cross-line mode were used. The GoogLeNet architecture was implemented. The coefficient of determination (R2), root mean square error (RMSE) and mean absolute error (MAE) were computed to evaluate the performance of the trained network. RESULTS: R2, RMSE, and MAE were 0.512, 0.350, and 0.321, respectively. R2 was higher in phakic eyes than in pseudophakic eyes. Multivariable regression analysis showed that a higher R2 was significantly associated with better BCVA (p < 0.001) and a higher standard deviation of BCVA (p < 0.001). However, the performance was worse in an external validation, with R2 of 0.19. R2 values for retinal vein occlusion and age-related macular degeneration were 0.961 and 0.373 in the internal validation but 0.20 and 0.22 in the external validation. CONCLUSION: Although underspecification appears to be a fundamental problem to be addressed in AI models for predicting visual acuity, the present results suggest that AI models might have potential for estimating BCVA from OCT in AMD and RVO. Further research is needed to improve the utility of BCVA estimation for these diseases.

Foods and Nutrients at Risk for Insufficient Intake by Community-Dwelling Healthy Older Women Eating Alone and Together in Japan-A Preliminary Finding.

Eating alone and poor dental status have been reported to influence dietary intake in older adults. First, we compared nutrient and food intake and dental markers between women eating alone and together, who participated in a home health management program conducted by Kanazawa Medical University. The results showed the significantly higher intake of fresh fruit and some micro-nutrients and a lower decayed, missing, and filled teeth (DMFT) index (better dental status) in women eating alone after adjusting for age, suggesting that dental status may mediate the association between commensality and dietary intake. Then, we investigated nutrients and foods at risk for insufficient intake and associated with increasing dental markers. The risks for the insufficient intake of protein and n-3 and n-6 polyunsaturated fatty acids (PUFAs) were significantly increased with an increasing DMFT index. The risk for n-3 PUFA intake also increased with increasing numbers of missing teeth in women. Foods at risk for insufficient consumption included beans for women with an increasing DMFT index and green and yellow vegetables, fresh fruits, and meat and fish for women with increasing numbers of missing teeth. These findings suggest that good health management, including the treatment of decayed teeth, is important for the prevention of malnutrition in community-dwelling healthy older women.

Analysis of the effect of brexpiprazole on sleep architecture in patients with schizophrenia: A preliminary study.

BACKGROUND: Brexpiprazole is an atypical antipsychotic drug widely used in Japan for the treatment of schizophrenia. Previous studies have investigated the therapeutic effects of some antipsychotics on sleep variables; however, to our knowledge, the effects of brexpiprazole on sleep architecture have not been examined in patients with schizophrenia. Therefore, we aimed to exploratorily investigate the effect of brexpiprazole on sleep variables measured by polysomnography in patients with schizophrenia. METHODS: This study included 10 patients with schizophrenia who were originally treated with haloperidol alone. Sleep variables of the participants were measured using polysomnography. After excluding those who did not meet the study criteria, seven patients (five men and two women; mean age [SD], 59.0 [10.0] years) were eligible for further analysis. Polysomnography was repeated at 4 weeks after the participants were prescribed brexpiprazole in addition to haloperidol. We compared the sleep architecture of the participants, measured using polysomnography, before and after taking brexpiprazole. RESULTS: Add-on brexpiprazole significantly prolonged rapid eye movement latency, increased the duration and percentage of stage N2 and stage N3 sleep (min, %), and decreased the duration and percentage of stage rapid eye movement sleep (min, %) at a significance level of nominal p < 0.05. CONCLUSION: Although not significant after correcting for multiple comparisons, the present results showed that add-on brexpiprazole could alter the sleep architecture of patients with schizophrenia. Future studies are warranted to replicate these findings and to further investigate the beneficial influence of brexpiprazole on sleep.

Hotspot analysis of COVID-19 infection using mobile-phone location data.

Restrictions on outdoor activities are required to suppress the COVID-19 pandemic. To monitor social risks and control the pandemic through sustainable restrictions, we focus on the relationship between the number of people going out and the effective reproduction number. The novelty of this study is that we have considered influx population instead of staying-population, as the data represent congestion. This enables us to apply our analysis method to all meshes because the influx population may always represent the congestion of specific areas, which include the residential areas as well. In this study, we report the correlation between the influx population in downtown areas and business districts in Tokyo during the pandemic considering the effective reproduction number and associated time delay. Moreover, we validate our method and the influx population data by confirming the consistency of the results with those of the previous research and epidemiological studies. As a result, it is confirmed that the social risk with regard to the spread of COVID-19 infection when people travel to downtown areas and business districts is high, and the risk when people visit only residential areas is low.

Application of deep learning as an ancillary diagnostic tool for thyroid FNA cytology.

BACKGROUND: Several studies have used artificial intelligence (AI) to analyze cytology images, but AI has yet to be adopted in clinical practice. The objective of this study was to demonstrate the accuracy of AI-based image analysis for thyroid fine-needle aspiration cytology (FNAC) and to propose its application in clinical practice. METHODS: In total, 148,395 microscopic images of FNAC were obtained from 393 thyroid nodules to train and validate the data, and EfficientNetV2-L was used as the image-classification model. The 35 nodules that were classified as atypia of undetermined significance (AUS) were predicted using AI training. RESULTS: The precision-recall area under the curve (PR AUC) was >0.95, except for poorly differentiated thyroid carcinoma (PR AUC = 0.49) and medullary thyroid carcinoma (PR AUC = 0.91). Poorly differentiated thyroid carcinoma had the lowest recall (35.4%) and was difficult to distinguish from papillary thyroid carcinoma, medullary thyroid carcinoma, and follicular thyroid carcinoma. Follicular adenomas and follicular thyroid carcinomas were distinguished from each other by 86.7% and 93.9% recall, respectively. For two-dimensional mapping of the data using t-distributed stochastic neighbor embedding, the lymphomas, follicular adenomas, and anaplastic thyroid carcinomas were divided into three, two, and two groups, respectively. Analysis of the AUS nodules showed 94.7% sensitivity, 14.4% specificity, 56.3% positive predictive value, and 66.7% negative predictive value. CONCLUSIONS: The authors developed an AI-based approach to analyze thyroid FNAC cases encountered in routine practice. This analysis could be useful for the clinical management of AUS and follicular neoplasm nodules (e.g., an online AI platform for thyroid cytology consultations).

Measures of Perceived Neighborhood Food Environments and Dietary Habits: A Systematic Review of Methods and Associations.

Access to healthy food is a necessity for all people. However, there is still a lack of reviews on the assessment of respondent-based measures of neighborhood food environments (perceived food environments). The aim of this systematic review was to evaluate the measurement tools for perceived food environments by five dimensions of food access and to obtain the overview of their associations with dietary habits among people aged 18 years and older in middle- and high-income countries. Observational studies using perceived food environment measures were identified through a systematic review based on two databases for original studies published from 2010 to 2020. A total of 19 final studies were extracted from totally 2926 studies. Pertaining to the five dimensions of food access, 12 studies dealt with accessibility, 13 with availability, 6 with affordability, 10 with acceptability, 2 with accommodation, and 8 with a combination of two or more dimensions. Perceived healthy food environments were positively associated with healthy dietary habits in 17 studies, but 8 of them indicated statistically insignificant associations. In conclusion, this review found accessibility and availability to be major dimensions of perceived food environments. The relationship between healthy food environments and healthy diets is presumably positive and weak.

Cytokine profiles of macular neovascularization in the elderly based on a classification from a pachychoroid/drusen perspective.

PURPOSE: To classify macular neovascularization (MNV) based on pachychoroid and drusen features and to examine the aqueous humor cytokine signatures of each group. METHODS: In total, 106 consecutive eyes with treatment-naïve MNV and 104 control eyes were examined. The aqueous humor concentrations of 15 cytokines were compared among the MNV groups classified based on the presence of drusen and/or pachychoroid features. Multidimensional scaling analysis was used to visualize the similarity level of the MNV subtypes according to their cytokine profiles. RESULTS: Thirty-one, 18, 43, and 10 eyes were classified into the pachychoroid-associated, drusen-associated, pachychoroid/drusen-associated, and non-drusen/non-pachychoroid MNV groups, respectively. Compared with the control group, cytokines were differently upregulated among the MNV groups. CRP and CXCL12 were significantly upregulated in all MNV groups, whereas CXCL13 and IL-8 were significantly upregulated in three MNV groups, excluding the non-pachychoroid/non-drusen-associated MNV group. Ang-2 was significantly upregulated in three MNV groups except the drusen-associated MNV group. PlGF was significantly upregulated in the pachychoroid-associated and drusen-associated MNV groups. CCL-2 was significantly upregulated in the pachychoroid-associated and pachychoroid/drusen-associated MNV groups. VEGF was downregulated in the pachychoroid-associated and drusen-associated MNV groups, respectively. Multidimensional scaling analysis showed a distinct cytokine profile for each MNV group. CONCLUSION: All MNV groups showed distinct cytokine profiles. Eyes with "neovascular age-related macular degeneration with drusen and concomitant pachychoroid" may share a similar etiology to those with "pachychoroid neovasculopathy" and "choroidal neovascularization with drusen," but have a distinct etiology to those without these. These findings suggest the importance of evaluating drusen and the choroid during the diagnosis of neovascular age-related macular degeneration.

An assessment of implementation gaps and priority recommendations on food environment policies: the Healthy Food Environment Policy Index in Japan.

OBJECTIVE: The current study aimed to evaluate policies and actions for food environments by the Japanese Government using the Healthy Food Environment Policy Index (Food-EPI). DESIGN: Public health experts rated the extent of implementation of food environment-related Policy and the Infrastructure-support components, compared with international best practices. Subsequently, the experts proposed and prioritised future actions to address implementation gaps in an online workshop. SETTING: Japan. PARTICIPANTS: A total of sixty-six experts rated policy implementation by the Japanese Government and twenty-three participated in the workshop on future actions. RESULTS: The implementations of regulations on unhealthy foods and non-alcoholic beverages were rated low in the domains of Food composition, Food labelling and Food promotion, Food prices and Food retail in the Policy component. The implementations of several domains in the Infrastructure-support component were, overall, rated at a higher level, specifically for monitoring and intelligence systems. Based on the rating, reducing health inequalities by supporting people, both economically and physically, was the highest priority for future actions in both components. CONCLUSIONS: The current study found that Japan has a robust system for long-term monitoring of population health but lacks regulations on unhealthy foods and non-alcoholic beverages compared with international best practices. The current study confirmed the importance of continuous accumulation of evidence through national monitoring systems. Developing comprehensive regulations to restrict food marketing, sales and accessibility of unhealthy foods and non-alcoholic beverages is needed to improve the health of food environments in Japan.

Rapid progression of chorioretinal atrophy in punctate inner choroiditis: a case report.

BACKGROUND: The chorioretinal inflammatory lesions occurring in punctate inner choroiditis evolve into punched-out atrophic scars. Typically, the progression is gradual. We report a case of highly myopic punctate inner choroiditis with rapid progression of chorioretinal atrophy. CASE PRESENTATION: A 48-year-old Japanese woman with high myopia presented with decreased visual acuity. Best-corrected visual acuity was 20/28 in the right eye and 20/16 in the left eye; axial length was 29.0 mm and 28.7 mm, respectively. Fundoscopy revealed an epiretinal membrane in the left eye. Three years later, the best-corrected visual acuity in the left eye had decreased to 20/33; at this time, the patient underwent vitrectomy with epiretinal membrane and internal limiting membrane peeling in this eye. Six months later, the best-corrected visual acuity in the left eye decreased suddenly to 20/100. Optical coherence tomography showed a nodule-like lesion in the outer retina with disruption of the retinal pigment epithelium and a focally thickened choroid, compatible with PIC. One month later, the choroidal thickness had decreased. The central chorioretinal atrophy expanded rapidly at a rate of 0.45 mm2/year over the next 3 years, and new areas of patchy focal chorioretinal atrophy developed in the perifovea. CONCLUSIONS: Rapid progression of chorioretinal atrophy was observed in a patient with punctate inner choroiditis. Because punctate inner choroiditis is often associated with degenerative myopia, the retina is fragile and may be susceptible to mechanical damage. This case report alerts clinicians to the need for careful management of patients with punctate inner choroiditis, especially after vitrectomy.

Factors Affecting Death and Severe Injury in Child Motor Vehicle Passengers.

Saving children from motor vehicle collisions is a high priority because the injury rate among motor vehicle passengers has been increasing in Japan. This study aimed to examine the factors that influence death and serious injury in child motor vehicle passengers to establish effective preventive measures. To identify these factors, we performed a retrospective study using a nationwide medical database. The data of child motor vehicle passengers younger than 15 years (n = 1084) were obtained from the Japanese Trauma Data Bank, registered from 2004 to 2019. Physiological variables, outcomes, and injury severity were compared between fatal and non-fatal patients and between those with and without severe injuries. Multivariate logistic regression analysis was performed to determine factors affecting fatality and severe injury. The Glasgow Coma Scale score (odds ratio (OR): 1.964), body temperature (OR: 2.578), and the Abbreviated Injury Scale score of the head (OR: 0.287) were identified as independent predictors of a non-fatal outcome. Systolic blood pressure (OR: 1.012), the Glasgow Coma Scale score (OR: 0.705), and Focused Assessment with Sonography for Trauma positivity (OR: 3.236) were identified as independent predictors of having severe injury. Decreasing the severity of head injury is the highest priority for child motor vehicle passengers to prevent fatality and severe injury.

Efficacy of Modified Treat-and-Extend Regimen of Aflibercept for Macular Edema from Branch Retinal Vein Occlusion: 2-Year Prospective Study Outcomes.

This study aimed to evaluate the long-term (24-month) efficacy and safety of a modified treat-and-extend (mTAE) regimen of aflibercept for macular edema (ME) due to branch retinal vein occlusion (BRVO). This was a prospective multicenter intervention study. We evaluated 50 eyes in 50 patients with ME due to BRVO enrolled between October 2016 and September 2017. The patients received intravitreal aflibercept (IVA) injections according to a mTAE regimen for 24 months. This study reports the secondary endpoints of best-corrected visual acuity (BCVA) and central subfield thickness (CST) at 24 months and compares them with previously reported primary endpoints. Compared with baseline BCVA and CST of 0.33 (0.27) and 488 (165) µm (mean (standard deviation)), respectively, BCVA and CST were significantly improved at 12 and 24 months (12 months: 0.059 (0.19) LogMAR and 299 (112) µm; 24 months: 0.034 (0.18) LogMAR and 272 (81) µm, respectively; both p < 0.0001). Over the 24-month period, the mean number of IVA injections and clinic visits was 7.4 (3.3) and 11.1 (2.0), respectively. The mTAE regimen of IVA injections for ME due to BRVO was effective for improving BCVA and reducing CST over 24 months. This regimen shows promise for reducing the number of injections and clinic visits.
