Design Retrospective, interventional case series. Methods Evaluation of 151 eyes of 151 patients who received trabeculectomy, ab-interno trabeculotomy or glaucoma drainage device (GDD) surgery. Dynamics of postoperative change in Bruch membrane opening minimum rim width (BMO-MRW) and peripapillary retinal nerve fibre layer thickness in spectral-domain OCT were assessed. Multiple linear regression models identified risk factors for occurrence and magnitude of SRDC. Results Compared with baseline, BMO-MRW increased significantly up to the 9-month follow-up (p=0.048) after surgery. A multiple regression model for all patients showed a high relative reduction in intraocular pressure (IOP) (standard β=−0.272, p<0.001), an early date of follow-up ( stand β=−0.280, p<0.001) and GDD as surgical procedure (standard β=0.169, p=0.027) as significant risk factors for SRDC. Within the first 9 months after intervention, a low postoperative IOP (standard β=−0.469, p < 0.001), a young age (standard β=−0.423, p<0.001) and a short axial length (standard β=−0.235, p = 0.040) had a significant impact on the BMO-MRW increase. Conclusion In this set of patients with glaucoma undergoing different types of IOP-lowering surgery, significant SRDC was seen up to 9 months postoperatively. Risk factors for the extent of SRDC were younger age at surgery, early hypotonia or low postoperative IOP and hyperopia. Data are available upon reasonable request.

Based on the upper quartile of AL elongation for people aged in their 20s, we defined AL elongation exceeding 0.033 mm per year as high AL elongation (HALE). We used multiple logistic regression analyses to assess potential risk factors for HALE.

Methods Retrospective cross-sectional data from patients in the Iranian TED (IrTED) registry, presented to Rassoul Akram Hospital, Tehran (March 2013–2023), were studied. Demographics, clinical indices of activity and severity and factors associated with delayed presentation were examined. Results Among 685 patients with TED, the mean diagnosis age was 37.79 years. A positive family history of thyroid dysfunction was reported by 37.66% (first-degree), 10.65% (second-degree) and 10.07% (both). According to the European Group on Graves’ Orbitopathy criteria, 56.49% had moderate-to-severe, 38.10% had mild, and 5.40% had sight-threatening TED. 59 patients were classified as active due to the recent onset of diplopia or proptosis, despite having an activity score of 1 or 2. Men were five times more likely to have active TED than women and 10-fold more likely to have sight-threatening TED. For every one-decade increase in age, the odds of having active TED and experiencing sight-threatening TED rise by approximately 72% and 96%, respectively. Conclusion Given the potential for targeted interventions such as smoking cessation, identifying high-risk relatives of thyroid dysfunction cases could help minimise disease progression and associated complications (primary prevention). Men and elderly patients are more likely to experience delayed diagnosis, leading to more severe presentations of TED (secondary prevention). Approximately one-fourth of patients had active TED, requiring anti-inflammatory treatment. However, the Clinical Activity Score threshold of 3 did not detect 34.91% of these active cases (tertiary prevention).

In 1950, it was estimated that the doubling time was 50 years; by 1980, it was 7 years and by 2010, 3.5 years. In 2020, it was projected to be just 73 days! To continue to practice evidence-based medicine and to provide the best possible care for our patients, clinicians need to adapt their strategies to keep their knowledge up to date. There will always be a role for critical appraisal of individual studies in the field of a clinician's practice, but with such an increase in the volume of published research, it becomes impossible to appraise all relevant material. For this reason, sources of distilled knowledge, such as the EGS Guidelines, become essential references for best practice medicine.\u0000Rigorous methods for evidence synthesis, such as the systematic reviews overseen by Cochrane, provide a comprehensive summary of the current state of knowledge for important clinical questions. However, for many clinical uncertainties, there is little or no high-quality evidence, let alone an evidence synthesis. Where evidence is lacking, practice guidance needs to be built from expert opinion and consensus, while acknowledging the limitations of such an approach. Expert opinion, derived from sound medical knowledge and years of practice experience, also has an important role in understanding the relevance of lines of evidence and the nuances of implementing them in practice. Thus, the expert commentary around the evidence base given in these Guidelines is essential for proper implementation of published evidence. Importantly, the EGS Guidelines also include 'Choosing wisely' elements indicating actions which should be avoided due to insufficient evidence and/or unsubstantiated belief.\u0000Guidelines need regular updating to take account of new knowledge and aspects of clinical care that have not been given sufficient emphasis in the past. This 6th Edition of the EGS Guidelines includes an updated 'evidence based' section with new clinical questions and evidence-based answers. The section 'What matters to patients' has also been updated, recognising that, because Guidelines are typically written by clinicians for clinicians, there have been gaps in understanding the patient perspective. The updated section now has direct input from the Expert by Experience patient advisors in the EGS Patient Involvement Project and includes eight Tips for Doctors in their communication with patients.\u0000The Guidelines team, led by Drs Pazos, Traverso and Viswanathan, is to be congratulated for the 6th Edition of the Guidelines, updating and enhancing the previous edition, while maintaining the highly success format which gives a framework for glaucoma care, based on evidence synthesis and consensus expert opinion, and presented as a 'How to' manual for patient diagnosis and management.\u0000David (Ted) Garway-Heath\u0000Glaucoma UK Professor of Ophthalmology, UCL</p>","PeriodicalId":9313,"journal":{"name":"British Journal of Ophthalmology","volume":"109 Suppl 1","pages":"1-212"},"PeriodicalIF":3.5,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145198368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Triptolide (TP) possesses many pharmacological properties, including immunosuppressive and anti-tumour effects. However, the effects of TP on ROP and its underlying mechanisms remain unclear. Purpose To investigate whether TP could inhibit the progression of OIR and to elucidate its underlying mechanisms. Methods The 7-day-old mice (P7) were kept in a 75% hyperoxia incubator for 5 days to induce an OIR model, followed by TP treatment for 5 days. Biomedical analysis and histopathological examinations of harvested retinas were conducted to explore the effect of TP. Furthermore, the impact of TP on retinal neovascularisation and microglial activation was validated using human umbilical vein endothelial cells (HUVECs) and human microglial clone 3 cells (HMC3s). Results TP treatment could significantly alleviate retinal pathological neovascularisation by inhibiting microglial activation. It downregulated the elevated levels of inflammatory cytokines (inducible nitric oxide synthase, tumour necrosis factor-α, Cox2 and interleukin (IL)-1β) and angiogenesis-related factors (hypoxia-inducible factor-1α, matrix metalloproteinase-2 and vascular endothelial growth factor-A) in OIR retinas and hypoxic HMC3s. HUVECs’ migration, proliferation and tube-forming capacities were also markedly suppressed under TP treatment. Further analysis suggested that TP exerted its anti-angiogenic effect in a way similar to NF-κB inhibitor (BAY117082). Conclusion TP alleviates pathological neovascularisation in OIR, potentially through the inhibition of inflammation mediated by NF-κB pathway. Data are available upon reasonable request. On reasonable request, the corresponding authors will provide the data that underpins the study's conclusions.","PeriodicalId":9313,"journal":{"name":"British Journal of Ophthalmology","volume":"55 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145017164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite over two decades of operation, its impact is not well-documented. We evaluated its effectiveness by comparing prevalence of visual impairment (VI), eyecare utilisation and service coverage among residents within and beyond a 5 km radius of VCs in Theni district, India. Methods We conducted a population-based cross-sectional study in Theni district, Tamil Nadu, from 2016 to 2018. Using cluster random sampling, we examined 7127 subjects aged ≥40 years. We categorised them into Group 1 (living within 5 km of VC) and Group 2 (living beyond 5 km). We compared the prevalence of VI, utilisation, cataract surgical coverage (CSC), effective cataract surgical coverage (eCSC), refractive error coverage (REC) and effective refractive error coverage (eREC) between the groups. Results Group 1 (n=3128) had lower age-sex-adjusted prevalence of VI (18.1% vs 25.2%) and higher eye care utilisation (66.7% vs 52.3%) compared with Group 2 (n=3999). Additionally, Group 1 demonstrated better CSC (63.9% vs 55.0%) and eCSC (44.8% vs 32.6%) than Group 2. REC for distance vision was 49.7% in Group 1 and 26.6% in Group 2, while eREC was 47.9% and 24.5%, respectively. Near vision coverage was 22.1% in Group 1 and 12.5% in Group 2. Conclusion VCs greatly enhance eye care in rural and underserved areas. Residents near VCs had lower prevalence of VI, higher utilisation and better coverage compared with those farther away, demonstrating the model’s effectiveness in improving eye care access and affordability. Data are available upon reasonable request. All data relevant to the study are included in the article or uploaded as supplementary information.","PeriodicalId":9313,"journal":{"name":"British Journal of Ophthalmology","volume":"33 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
