ObjectiveRetinal vein occlusion （RVO） is the second most common vascular disease leading to vision loss. Since its pathogenesis remains unclear， current Western medical treatments primarily target complications such as macular edema and neovascularization. The main therapeutic approaches include intravitreal injections of anti-vascular endothelial growth factor （VEGF） agents or corticosteroids， laser photocoagulation， and pars plana vitrectomy. However， these treatments cannot fully reverse disease progression or structural damage. Traditional Chinese medicine （TCM） has unique advantages in the clinical diagnosis and treatment of RVO， and integrated Chinese and Western medicine approaches may offer better clinical outcomes. This study， based on the clinical manifestations of RVO， systematically reviews the existing literature and evaluates the alignment of current RVO animal models with clinical manifestations. The aim is to identify the characteristics and limitations of existing models and provide recommendations and prospects for developing RVO animal models featuring the combination of disease and syndrome. MethodsDatabases including CNKI， Wanfang Data， PubMed， and Web of Science were searched with the keywords of "retinal vein occlusion" and "animal model". Model characteristics were assessed based on the diagnostic criteria for diseases and syndromes in both TCM and Western medicine. The alignment of each model with clinical manifestations was analyzed and evaluated. ResultsThe available RVO models were primarily established via methods such as laser photocoagulation， photodynamic therapy， diathermy， intravitreal drug injection， and mechanical modeling. These models demonstrated moderate overall alignment with clinical manifestations， mainly reflecting disease characteristics. However， they generally lack representation of TCM syndrome features. ConclusionExisting RVO models are predominantly based on Western medicine and lack TCM syndrome features. Western medical treatments for RVO have certain limitations， while syndrome differentiation and treatment in TCM offer potential advantages. Future research should focus on developing disease-syndrome integrated animal models that incorporate both pathological features and TCM syndrome characteristics. This approach will enhance the design of RVO models and facilitate both basic and clinical research， which make it a scientifically valuable and necessary endeavor.

Abstract The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas：optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

Objective To explore the clinical factors influencing complete response in patients with locally advanced rectal cancer (LARC) after neoadjuvant chemoradiotherapy (nCRT). Methods Clinical data of LARC patients treated in the Department of Radiation Oncology at Beijing Shijitan Hospital between January 2013 and December 2024 were retrospectively collected. All patients received nCRT, after which surgery or a watch-and-wait approach was adopted based on treatment response. Univariable and multivariable logistic regression analyses were performed to identify prognostic factors influencing complete response. A clinical prediction model was constructed based on the multivariable analysis results, and its predictive performance was evaluated using the receiver operating characteristic curve. Results A total of 113 eligible patients were included. After nCRT, 19 patients (16.8%) achieved complete response, including 3 with clinical complete response and 16 with pathological complete response. Univariable analysis indicated that pretreatment clinical N stage, extramural venous invasion, carcinoembryonic antigen level, and neoadjuvant treatment regimen were associated with complete response after nCRT (P<0.05). Multivariable logistic regression analysis identified pretreatment extramural venous invasion, carcinoembryonic antigen level, and neoadjuvant treatment regimen as independent influencing factors for complete response (P<0.05). A prediction model incorporating these independent factors yielded an area under the receiver operating characteristic curve of 0.813 (95% confidence interval: 0.713-0.913), with a sensitivity of 89.5% and a specificity of 60.6%, demonstrating good predictive performance. Conclusion Pretreatment extramural venous invasion, carcinoembryonic antigen level, and neoadjuvant treatment regimen are independent factors influencing complete response after nCRT in LARC patients. The prediction model combining these factors may assist in evaluating treatment efficacy following nCRT in LARC patients.

Objective To compare the dosimetric and radiobiological differences of helical tomotherapy (HT) and volumetric modulated arc therapy (VMAT) in craniospinal irradiation. Methods The CT images of 15 patients who received craniospinal irradiation in our hospital were selected. The target volumes and organs at risk (OARs) were contoured, and HT and VMAT plans were designed. The dosimetric parameters of the two plans were compared. A Matlab program based on equivalent uniform dose was developed to calculate the normal tissue complication probability (NTCP). The NTCP values of the two plans were compared. Results The homogeneity index of the target volume in the HT group was better than that in the VMAT group, with values of 0.06 ± 0.01 and 0.08 ± 0.24, respectively, and the difference was statistically significant (P=0.03). However, there was no significant difference in the conformity index of the target volume (P>0.05). There were significant differences in key indicators (D_mean, V₅, D_max) of the lungs, liver, lens, and eyeballs between the two groups (P<0.05). Regarding OARs, the NTCP values of the lens, optic chiasm, lungs, and liver in the HT and VMAT groups were as follows: 0.04 ± 0.03 vs. 0.1 ± 0.06 in the left lens, 0.04 ± 0.06 vs. 0.1 ± 0.07 in the right lens, 0.16 (0.14-0.17) vs. 0.21 (0.18-0.24) in the optic chiasm, 3.89 × 10⁻⁴ (2.45 × 10⁻⁴-7.3 × 10⁻⁴) vs. 8.95 × 10⁻⁴ (5.19 × 10⁻⁴-1.75 × 10⁻³) in the lungs, and 3.45 × 10⁻⁸ (6.0 × 10⁻⁹-1.036 × 10⁻⁷) vs. 9.54 × 10⁻⁸ (1.70 × 10⁻⁸-2.056 × 10⁻⁷) in the liver; the HT group was superior to the VMAT group, and all differences were statistically significant (P<0.05). The NTCP values of the heart in the two groups were 1.35 × 10⁻⁸ (6.34 × 10⁻⁹-2.06 × 10⁻⁹) vs. 5.06 × 10⁻⁹ (2.29 × 10⁻⁹-7.9 × 10⁻⁹), significantly lower in the VMAT group than in the HT group (P<0.05). Conclusion HT has high homogeneity and consistency. The two plans have their own advantages in OAR protection. For OARs with no significant differences in physical dosimetry, NTCP results can be used as a reference. Therefore, comparing the dosimetric parameters and OAR NTCP of HT and VMAT plans can help select the optimal clinical treatment strategy.

Intravitreal anti-vascular endothelial growth factor(anti-VEGF)therapy has been widely used, but the variability in its therapeutic efficacy limits individualized treatment. In recent years, the application of artificial intelligence(AI)has opened up new avenues for personalized treatment response prediction, and its core branches include machine learning(ML)and deep learning(DL). This review systematically retrieved and analyzed 41 relevant studies published up to April 2025. Comprehensive analysis reveals that AI predictive models are evolving from forecasting single endpoints(such as visual acuity or central retinal thickness)to integrating multi-dimensional endpoints(encompassing anatomical, functional, and treatment demand parameters)and generating predictive imaging outputs. In terms of technical approaches, DL models(28 studies, accounting for 68.3%)dominate this field due to their robust image interpretation capabilities, while ML models(10 studies, 24.4%)retain significant value in the analysis of structured clinical data. Cross-disease comparisons indicate that research efforts are most concentrated on age-related macular degeneration(ARMD)and diabetic macular edema(DME), with shared conceptual frameworks for model construction, yet distinct anatomical and functional indicators are prioritized for each disease. Currently, the field confronts several key challenges, including insufficient prospective clinical validation, limited model interpretability(the “black box problem”), and a scarcity of high-quality multi-center datasets. Moving forward, it is imperative to advance real-world validation and develop explainable AI techniques to expedite the clinical translation of these predictive models.

AIM: To evaluate the reliability of a digital multimedia system for measuring near-distance horizontal heterophoria.METHODS: This cross-sectional diagnostic study enrolled patients with refractive errors who visited Shantou Aier Eye Hospital from May 2023 to August 2025, presenting with symptoms of visual fatigue, undergoing myopia management, or receiving routine ophthalmic examinations, and who completed heterophoria testing during this period. All patients wearing full refractive correction underwent near-distance(0.4 m)horizontal heterophoria measurement in a random order using the digital multimedia system, the Von Graefe method, and the Maddox rod method. Two consecutive measurements were performed for each method. The intraclass correlation coefficient(ICC)was used to analyze the measurement repeatability of each method, and Bland-Altman analysis and Spearman correlation analysis were employed to evaluate the consistency between the digital multimedia system and the two traditional methods.RESULTS: A total of 60 patients(120 eyes)were included, comprising 27 males and 33 females, with a mean age of 21.03±7.24 y. Repeatability analysis showed that the ICC for the digital multimedia system was 0.960(95%CI: 0.934-0.976), for the Von Graefe method was 0.979(95%CI: 0.964-0.987), and for the Maddox rod method was 0.956(95%CI: 0.926-0.973), all indicating excellent repeatability. Bland-Altman analysis revealed a mean difference of 0.367△ [95% limits of agreement(LoA): -2.97△ to 3.70△] between the Von Graefe method and the digital system, and a mean difference of 0.067△(95% LoA: -3.05△ to 3.19△)between the Maddox rod method and the digital system. Both differences were within the clinically acceptable range(difference <4△). Spearman correlation analysis showed positive correlations between the digital system and the Von Graefe method(rs=0.867)and between the digital system and the Maddox rod method(rs=0.777, all P<0.001).CONCLUSION: The digital multimedia system demonstrates high repeatability and good consistency with the traditional Von Graefe and Maddox rod methods for measuring near-distance horizontal heterophoria. It shows promise as a new and effective tool for clinical near-distance horizontal heterophoria measurement.

AIM: To investigate the relationship between the levels of interleukin-6(IL-6)and IL-2 in aqueous humor and the severity of optic nerve injury in patients with primary open-angle glaucoma(POAG), and to construct a decision tree model for the severity of optic nerve injury in POAG patients.METHODS: A prospective study was conducted on 107 patients(107 eyes)with POAG who were admitted to the hospital from May 2021 to October 2023. According to the mean defect(MD)value, the degree of optic nerve injury was judged and divided into three groups: mild, moderate and severe. The general data, IL-6 and IL-2 levels in aqueous humor of patients with different severity of optic nerve injury were compared, and the correlation between the levels of IL-6 and IL-2 in aqueous humor and the severity of optic nerve injury in POAG patients was analyzed. Multivariate Logistic regression analysis was used to test the influencing factors of the severity of optic nerve injury in POAG patients, and the decision tree model was constructed based on influencing factors.RESULTS: The proportion of patients with hypertension, intraocular pressure and binocular intraocular pressure difference in the severe group was higher than that in the mild and moderate groups, and the levels of IL-6 and IL-2 in the aqueous humor were significantly lower than those in the mild and moderate groups(all P<0.05). The levels of IL-6 and IL-2 in aqueous humor of POAG patients were negatively correlated with the severity of optic nerve injury(r=-0.361, -0.358, all P<0.001). Hypertension, intraocular pressure, binocular intraocular pressure difference, IL-6 and IL-2 levels in aqueous humor were independent factors affecting the degree of optic nerve injury in POAG patients(all P<0.05). Based on the above factors, a decision tree model was constructed, and three explanatory variables of IL-6, IL-2 levels in aqueous humor and hypertension were screened out. Among them, IL-2 level in aqueous humor was the most important root node variable and the most important predictor. The AUC of the decision tree model was 0.710(95% CI: 0.599-0.820, P=0.001), the sensitivity was 0.581, the specificity was 0.737, and the Youden index was 0.318, with a high predictive value.CONCLUSION: The levels of IL-6 and IL-2 in aqueous humor were significantly correlated with the severity of optic nerve injury in POAG patients. The decision tree model based on hypertension, intraocular pressure, binocular intraocular pressure difference, IL-6 and IL-2 levels in aqueous humor has a high evaluation value for the severity of optic nerve injury in POAG patients.
