RESUMEN
Diabetic retinopathy is one of the microvascular complications of diabetes and a major cause of blindness in adults. Early screening is an effective way to reduce blindness caused by diabetic retinopathy. The diabetic retinopathy is one of the chronic retinal diseases highlighted in the "14th Five-Year" National Eye Health Plan (2021-2025). The establishment of effective and practical community screening model is a powerful guarantee to complete early screening. It is of great significance to standardize screening methods, screening personnel duties, equipment allocation, referral conditions and screening sustainability. Chinese fundus disease and related field experts developed the consensus through a serious, comprehensive, and complete discussion, to provide more reference for establishing a suitable community screening model of diabetic retinopathy and increasing the screening rate of diabetic retinopathy.
RESUMEN
Diabetes retinopathy (DR) is listed as one of the chronic diseases that should be focused on in the "14th Five-Year" National Eye Health Plan (2021-2025). Early screening is one of the effective measures to reduce blindness caused by DR. Establishing an efficient and practical community screening model is a powerful guarantee for completing early screening. The Ocular Fundus Diseases Group of the Ophthalmology Branch of the Chinese Medical Association has led the development of Expert consensus on community screening of diabetic retinopathy among DR community screening experts that is suitable for the current national situation, in order to guide and promote the further improvement of DR community screening work in China. This Expert Consensus provides detailed specifications on the current domestic trend of DR, the necessity of screening, the role of artificial intelligence grading, screening process, and quality control. This interpretation further emphasizes the importance of DR community screening, while emphasizing the responsibilities of different departments in the screening process. Finally, recommendations are provided for the sustainability of DR community screening. It is hoped that the screening rate of DR in China can be improved and blindness can be reduced by DR through Expert consensus on community screening of diabetic retinopathy and interpretation of the content.

RESUMEN
ObjectiveThis study aimed to analyze the difference in setup error before and after correction of systematic error. To determine the most appropriate image-guided strategy during HT treatment， we use different scanning ranges and image-guidance frequencies in patients with nasopharyngeal carcinoma （NPC） treated with helical tomotherapy （HT）. MethodsFifteen patients with NPC who received HT treatment in Sun Yat-sen University Cancer Center from October 2019 to February 2020 were selected. Megavoltage computed tomography （MVCT） scanning was performed before each treatment. After five times of radiotherapy， system-error correction was performed to adjust the setup center. The setup errors before and after the correction of systematic errors， as well as the setup errors of different scanning ranges and different scanning frequencies， were collected for analysis and comparison. ResultsWhen comparing the setup errors before and after the correction of systematic error， the differences in setup errors in the left–right （LR）， superior–inferior （SI）， and anterior–posterior （AP） directions were statistically significant （P<0.05）.The different scanning ranges of "nasopharynx + neck" and "nasopharynx" were compared， and a statistically significant difference was found in yaw rotational errors （P<0.05）. In the comparison of daily and weekly scan frequency after system-error correction， a significant difference was found in AP direction （P<0.05）. ConclusionDuring radiotherapy for NPC， the systematic error can be corrected according to the first five setup errors， and then small-scale scanning was selected for image-guided radiotherapy every day.
RESUMEN
Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.
RESUMEN
Objective·To explore the association between high myopia and life quality among children.Methods·Cross-sectional study method was adopted in this study.Highly myopic children aged 4-10 from 16 districts in Shanghai were enrolled through Shanghai Child and Adolescent Large-scale Eye Study-High Myopia Registration Study.Baseline data for spherical equivalent after cycloplegia and questionnaire data in 2020 were collected.Emmetropic children aged 4-10 from 16 kindergartens and elementary schools in Jing'an District and Pudong New Area were enrolled.The uncorrected visual acuity,corrected visual acuity and spherical equivalent without cycloplegia were measured through myopia screening in schools,and the questionnaire on quality of life was filled out.Quality of life was measured by the Strengths and Difficulties Questionnaire(SDQ)and EuroQol Five Dimensions Questionnaire Visual Analogue Scale(EQ-VAS).After describing and testing the differences in variable distributions between the highly myopic children group and the emmetropic children group,the differences in life quality between the two groups,and the association between spherical equivalent and life quality scores of the highly myopic children were examined by a linear regression model.Results·A total of 193 children with high myopia and 209 children with emmetropia were enrolled.There were statistically significant differences in age[(9.58±0.94)years vs(7.63±1.50)years,P＜0.001]and gender distribution(46.6％males vs 62.7％males,P=0.00l)between the highly myopic children and emmetropic children.After adjusting for age and gender,it was found that there was no statistically significant difference in SDQ score between the highly myopic children and emmetropic children(β=0.313,95％CI-0.723-1.349,P=0.553),but the EQ-VAS score in the highly myopic children was lower than that in the emmetropic children(β=-3.805,95％CI-6.593--1.017,P=0.008).There was no significant relationship between spherical equivalent and SDQ score(β=0.297,95％CI-0.035-0.628,P=0.079)and EQ-VAS score(β=0.579,95％CI-0.330-1.489,P=0.21 1)in the highly myopic children.Conclusion·In children with high myopia,self-evaluated overall health status reflected by EQ-VAS score is poorer compared with that in children with emmetropia.However,the EQ-VAS score is not associated with the degree of high myopia.
RESUMEN
The Evidence-based guidelines for diagnosis and treatment of age-related macular degeneration in China (2023) is the first evidence-based clinical practice guidelines for the diagnosis and treatment of age-related macular degeneration (AMD) in China that strictly follows the WHO guideline formulation and international guideline standards. Based on the latest evidence-based medical evidence and the rapid development of ocular fundus imaging technology, the new version of the guidelines has been updated in the diagnosis, treatment and follow-up of AMD. Based on the origin and presence of neovascularization in retinal tissue, the macular neovascularizations are divided into type 1, type 2 and type 3 macular neovascularization (MNV). Optical coherence tomography (OCT) plus OCT angiography is recommended as the useful diagnostic method in neovascular AMD patients. Antioxidant vitamins, zinc, lutein, zeaxanthin, or a mix of antioxidant vitamins and minerals are recommended to prevent the progression of early to intermediate AMD. Intravitreal administration of anti-vascular endothelial growth factor (VEGF) agents is the first-line treatment for neovascular AMD, and once a month for the first 3 months plus treatment and prolonged administration regimen shows benefit to a certain extent. For poor response and non-response neovascular AMD patients, the clinician should decide the next treatment plan based on comprehensive consideration. Close observation is recommended for non-exudative MNV, and anti-VEGF therapy should be used promptly once non-exudative MNV transfer to exudative MNV. It is hoped that this guideline will improve the diagnosis, treatment, prevention and follow-up of AMD in China.
RESUMEN

Promoting the systematic management of DR and constructing the chronic disease management system are the key to the next step of national eye health work. It is necessary to further improve the management mode of the whole course of DR patients with chronic eye disease through the joint action of medical security system at all levels, including strengthening supporting policies of primary medical institutions, optimizing medical service mode and process, strengthening scientific education to improve patients' and doctors' disease cognition, and updating authoritative Chinese DR guidelines to standardize diagnosis and treatment. It is hoped that the low vision and blindness caused by DR in China can be greatly reduced after the implementation of the "14th Five-Year" Plan for Eye Health.
RESUMEN
Chronic disease is a major threat to human health. Fundus disease has become a major ophthalmic disease affecting daily life. Although great breakthroughs have been made in the treatment, compared with other chronic disease management, the management of patients with fundus disease is still in its infancy. To strengthen the management exploration of patients with fundus diseases, establish a management model of fundus diseases and strive to improve patients' awareness of fundus diseases and adherence to treatment and follow-up are the great challenges at present. All ophthalmic centers should strengthen patient education, establish a regional cooperation network, support the construction of grassroots medical capacity, cultivate talents, enhance training, promote the standardized treatment of fundus diseases, standardize fundus imaging inspection and diagnosis, and promote the homogeneous construction of diagnosis and treatment of chronic fundus diseases. We will accelerate the construction of a hierarchical diagnosis and treatment system and the ability to link consultation and referral. Through systematic management and intervention of fundus diseases, a large number of patients with fundus diseases will receive early screening, diagnosis, standardized continuous treatment and systematic management, and improve the quality of life of patients with fundus diseases.
RESUMEN
Intravitreal drug injection is a treatment for common chronic fundus diseases such as age-related macular degeneration and diabetic retinopathy. The "14th Five-Year" National Eye Health Plan (2021-2025) recommends focusing on fundus diseases and improve the management mode of patients with chronic eye diseases. Therefore, it is imperative to explore how to further optimize the service process of intravitreal injection under the premise of guaranteeing patients' medical safety, to promote medical service efficiency and standardized management level and improve the medical experience of patients. Based on the quality control standard of vitreous cavity injection for retinopathy in China, Chinese fundus disease and related field experts developed the present expert consensus on the establishment of a one-stop intravitreal injection model and the management of its organization after a serious, comprehensive, and complete discussion, focusing on a standardized operation process, quality control, and safety management, providing more references for establishing a suitable intravitreal injection management model for ophthalmology and promoting the development of diagnostic and treatment models for fundus disease in China.
RESUMEN
Maculopathy caused by various fundus diseases in the late stage is a common cause of low vision. Medical technology is difficult to reverse the loss of macular function currently, so interventions that help improve the visual system, utilize residual visual function, and improve quality of life deserve attention. Damage to the fovea of the macula does not mean that the entire retinal function is impaired. There may be one or more retinal regions adjacent to the fovea that can serve as a fixation center. It is possible to form stable paracentral fixation, complete functional remodeling of the visual system, and effectively utilize residual visual function by taking appropriate training on these potential paracentral fixation points for most patients. In 2021, a clinical guideline has been published for low vision rehabilitation in China. In order to strengthen the precise management of diseases and develop a standard operating procedure for visual training specifically for patients with low vision due to macular disease, the National Clinical Research Center for Eye Diseases initiated and organized relevant domestic experts, utilizing the latest research experience at home and abroad, and through repeated discussions, this consensus (International Practice Guideline Registration Number: PREPARE-2023CN199) was formed as a reference for ophthalmologists, optometrists and rehabilitation physicians in their clinical research and practice.
RESUMEN
High myopia has a high genetic tendency, it not only shows in the excessive elongation of the axial length, but also lends to the formation and progression of various eye lesions, such as peripheral retinopathy, optic disc changes, posterior staphyloma, and myopic maculopathy, due to the mechanical stretching of the axial length to the ocular structure. In addition, high myopia increases the risk of several complications, such as glaucoma, cataract, and corneal disease. All these pathological changes will affect visual function and lead to irreversible vision impairment and blindness in the future. Therefore, it is important to pay attention to screening for optic disc abnormalities and posterior staphyloma, and regular monitor the changes of fundus, intraocular pressure, and lens. At the same time, high myopia has an impact on personal life such as study, psychology, sport, and work, and can reduce the quality of life as well as increase the cost of health care. The clinic should pay more attention to high myopia, prevent and control the development of high myopia from an early stage, in order to minimize its impact on ocular structure and visual function as well as its hazard to personal life and society.
RESUMEN
The high prevalence of myopia is a global public health concern, and the risk of associated complications is becoming increasingly apprent.The International Myopia Institute (IMI) was established in 2015 to promote scientific research and clinical practice in myopia control, and IMI published the White Paper on Myopia Prevention and Control on the diagnosis, treatment, and management of myopia.In 2023, the IMI released the series three of the White Paper on Myopia Prevention and Control, which delves deeper into key issues in myopia research and management.The white paper focuses on non-pathological changes observed in axial myopia, and the role of the choroid in eye growth and myopia management.It also reviews the evidence for myopia incidence, progression and management in atypical populations, such as infants, pre-school children, and young adults.It provides recommendations and strategies for clinical practice in myopia management and summarizes important new findings in myopia research since 2019, which are summarized into the IMI 2023 Digest.This article aims to interpret the key contents of the series three of the White Paper on Myopia Prevention and Control, to help professionals involved in myopia control to stay informed about the latest evidence from international research, to optimize strategies for preventing and treating myopia-related diseases, and ultimately to promote the development of myopia research and management in China.
RESUMEN
Diabetes mellitus (DM) is a chronic metabolic disease caused by multiple etiologies.Diabetic retinopathy (DR), as a primary ocular complication of DM, is the leading cause of blindness among working-age adults in the world.With the rapid increase of diabetes incidence worldwide, the diagnosis of DR is often delayed because few symptoms of the retinal vessel-nurse unit lesion are found in early DR.Therefore, the early diagnosis, prevention and treatment of DR are facing much more challenges.At present, the early clinical biomarkers of DR, such as glycosylated hemoglobin and blood glucose, are of great value in predicting and preventing the occurrence and development of DR, but there is still a lack of research on the pathological effect of metabolic heterogeneity and its potential induction of DR.Multi-omics methods, such as metabolomics and single-cell transcriptome, as well as deep learning techniques, are powerful tools for the study of DR pathophysiological processes, which can be used to reveal the metabolic characteristics of DR, discover early biomarkers and new metabolic pathways and identify targets for treatment.Future advances which aim to diagnose and treat DR should consider the metabolic remodeling induced by genetic background and environmental factors comprehensively, combine omics approaches and the measurement of clinical indicators of DR occurrence and development to find biomarkers of early DR and targets so as to achieve early prediction and accurate prevention of DR.
RESUMEN
Myopia has become a major problem that threatens human health worldwide. Complications caused by high myopia are one of the leading causes of low vision and blindness. As a chronic disease that seriously threatens ocular health in the clinical practice and public health fields, the prevention and control of high myopia should actively promote a tertiary prevention strategy, and take advantages of the latest fundus imaging technology and big data technology, artificial intelligence to explore the evolution mechanism of "myopia→high myopia→pathological myopia" . Special efforts should be focused on the establishment of a scientific myopia prediction model, implementation of effective high myopia monitoring and management, and early detection and treatment of complications of high myopia to reduce the incidence of low vision and blindness.
RESUMEN
The main fundus changes of pathologic myopia (PM) are posterior staphyloma (PS) and myopic maculopathy (MM), which includes myopic atrophy maculopathy (MAM), myopic tractional maculopathy (MTM), myopic neovascular maculopathy (MNM) and so on. The clinical manifestations of PM-related fundus lesions are complex, and the classification of PM has been a research hotspot in recent years. The proposal of each classification shows an increasing understanding of PM, and each classification has its advantages but also imperfections. For MM, it is recommended to refine the MTM classification based on the ATN classification and adjust it according to the internal correlation between MAM and MNM. The rapid development of modern imaging technology will promote the continuous update of the classification, and its further improvement will also help to understand the development process of PM, which has important clinical value in preventing its occurrence and progression.

RESUMEN
In the era of the new healthcare reform, high-quality cost accounting can effectively enhance the business performance of public hospitals. Compared with single-campus hospitals, the cost accounting of multi-campus hospitals is faced with greater complexity and challenges. The authors analyzed cost accounting problems found in the latter, namely the lack of top-level design in the construction of a fine multi-campus cost accounting system, difficulty of reasonable collection and allocation of various costs, lack of strong information support, outdated research methods used in item cost accounting among others, as well as their causes. On such basis, the authors put forward countermeasures for high-quality cost accounting in multi-campus hospitals, for the purpose of fully leveraging the leadership of cost control in the high-quality development of public hospitals.
RESUMEN
Pulp loss is accompanied by the functional impairment of defense, sensory, and nutrition supply. The approach based on endogenous stem cells is a potential strategy for pulp regeneration. However, endogenous stem cell sources, exogenous regenerative signals, and neovascularization are major difficulties for pulp regeneration based on endogenous stem cells. Therefore, the purpose of our research is to seek an effective cytokines delivery strategy and bioactive materials to reestablish an ideal regenerative microenvironment for pulp regeneration. In in vitro study, we investigated the effects of Wnt3a, transforming growth factor-beta 1, and bone morphogenetic protein 7 (BMP7) on human dental pulp stem cells (h-DPSCs) and human umbilical vein endothelial cells. 2D and 3D culture systems based on collagen gel, matrigel, and gelatin methacryloyl were fabricated to evaluate the morphology and viability of h-DPSCs. In in vivo study, an ectopic nude mouse model and an in situ beagle dog model were established to investigate the possibility of pulp regeneration by implanting collagen gel loading BMP7. We concluded that BMP7 promoted the migration and odontogenic differentiation of h-DPSCs and vessel formation. Collagen gel maintained the cell adhesion, cell spreading, and cell viability of h-DPSCs in 2D or 3D culture. The transplantation of collagen gel loading BMP7 induced vascularized pulp-like tissue regeneration in vivo. The injectable approach based on collagen gel loading BMP7 might exert promising therapeutic application in endogenous pulp regeneration.
