The aims and methodologies of the AIDA registries have been meticulously outlined in published papers. (3-7) Employing a physician-driven, population- and electronic-based approach, these registries utilize the REDCap platform for comprehensive data collection. Data are meticulously gathered both retrospectively and prospectively, covering various aspects including demographic, genetic, clinical, laboratory, instrumental, and treatment details. Crucially, the employment of standardized common data elements ensures efficient data entry and consistency across diverse sites.&lt;/p&gt;\u0000 \u0000 &lt;p&gt;Maintaining utmost respect for patient privacy and data security, the AIDA registries strictly adhere to EU General Data Protection Regulations and international standards. Advanced pseudonymization tools like SPIDER safeguard patient identities, facilitating secure data exchange between registries without compromising confidentiality. The AIDA network boasts a vast membership, spanning 235 clinical sites across 46 countries and five continents, with 683 investigators actively contributing to ongoing research efforts. Since the launch of the Registries on ocular inflammatory diseases, enrollment has exceeded 4,020 patients, underscoring the pivotal role of recruitment activities in routine clinical practice.&lt;/p&gt;\u0000 ","PeriodicalId":6915,"journal":{"name":"Acta Ophthalmologica","volume":"103 S284","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/10.1111/aos.16885","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functional OCT represents a leap forward in imaging technology by integrating traditional OCT with functional measurements like blood flow, tissue stiffness, tissue birefringence, oxygen metabolism and optoretinography. This comprehensive may offers deeper insights into ocular health and disease progression than conventional structural OCT. By capturing both structural and functional information, Functional OCT may our ability to detect and monitor conditions such as myopia, glaucoma, diabetic retinopathy, and age-related macular degeneration. Deep Learning, on the other hand, is a subset of artificial intelligence, analyzing the vast amounts of data generated by ocular imaging modalities. Through sophisticated algorithms, Deep Learning can identify intricate patterns and features in images that may elude human interpretation. This capability not only enhances diagnostic accuracy but also aids in automating image analysis, improving efficiency, and reducing the burden on healthcare professionals. The synergy between Functional OCT and Deep Learning holds immense promise for the future of ocular imaging. By integrating these technologies, we can achieve a comprehensive understanding of ocular physiology and pathology while enhancing diagnostic accuracy and efficiency. This convergence may lead to the development of advanced systems capable of real-time analysis and interpretation, facilitating point-of-care diagnostics and remote monitoring.

However, photoreceptors do not regenerate in mammals including humans, thus cell transplantation has emerged as a potential treatment approach for blinding diseases. Therefore, a pipeline for assessing the transplantation of human stem cell-derived photoreceptors into mouse models of retinal generation was developed. Human photoreceptor-specific reporter iPSC-derived retinal organoids were used for isolation of donor cells via flow-cytometry. After transplantation we observed extensive incorporation of human photoreceptors in mice with cone dysfunction/loss. This incorporative phenotype was validated in both cone-only as well as pan-photoreceptor transplantations. Rather than forming a glial barrier, Müller cells extend throughout the graft, and additionally form a series of adherens junctions between mouse and human cells, reminiscent of an outer limiting membrane. Donor-host interaction appears to promote transplant polarization as well as development of morphological features critical for light detection, namely formation of inner- and outer-segments mainly oriented towards the host retinal pigment epithelium. Putative synapse formation and graft function was observed both at the structural level and by electrophysiological analysis using micro-electrode recordings. Transcriptomic analysis reveals increased expression of cone photoreceptor maturation genes with time after transplantation, in comparison to cones of age-matched retinal organoids in vitro. While highly integrative donor cell clusters were observed in partially degenerated recipients, transplantation into hosts with late-stage degeneration, i.e. with complete photoreceptor loss, lead to more wide-spread distribution of donor cells within the sub-retinal space and reduced signs for integration and maturation. Thus, interaction with the host retina appears to be important for graft integration, maturation, polarization and function. Overall, these results show that human photoreceptors interact readily with a partially degenerated mouse retina.</p>\u0000 \u0000 <p>Funding:</p>\u0000 \u0000 <p>BMBF – ReSight (01EK1613A)</p>\u0000 \u0000 <p>DFG – AD375/7-1 (SPP2127), SEQ2146</p>\u0000 \u0000 <p>FFB – TA-RM-0522-0824-TUD-TRAP</p>\u0000 </section>\u0000 </div>","PeriodicalId":6915,"journal":{"name":"Acta Ophthalmologica","volume":"103 S284","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/10.1111/aos.16893","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Immunohistochemical, histochemical, and electron transmission microscopy assays were performed.</p>\u0000 \u0000 <p><b>Results:</b> Molecular analysis showed that arteriolar annuli endothelial cells showed a decreased expression of PECAM-1 together with an increased expression of NADPH-diaphorase in comparison with other regions of retinal arterioles.

Thus, its increase indicates NO synthesis suggesting localized vasodilation and decrease of platelet aggregation at arteriolar annuli. An increased expression of von Willebrand factor in concomitance with a higher presence of Weibel-Palade bodies was also observed in endothelial cells at the arteriolar annuli, suggesting that von Willebrand factor is stored and released in a regulated manner. Furthermore, transmission electron microscopy showed the presence of two endothelial cell subtypes in arteriolar annuli: activated endothelial cells, and shear stress-adapted endothelial cells.

Additionally, it aims to develop a convolutional neural network (CNN) for assisted diagnosis using these measurements.</p>\u0000 \u0000 <p><b>Methods:</b> Two cohorts, one with relapsing-remitting MS (RRMS) patients (<i>n</i> = 79) and another with healthy controls (<i>n</i> = 69), were recruited. Structural retinal measurements were obtained using the Spectralis OCT device. The analysis focused on thickness differences in nine retinal layers and their inter-eye asymmetry. Statistical methods included the Shapiro-Wilk test, Student's t-test, χ2 test, and area under the receiver operating characteristic (AUROC) curve. A CNN was trained to classify patients and controls based on the most discriminant retinal measurements.</p>\u0000 \u0000 <p><b>Results:</b> The study found significant thinning in the ganglion cell layer (GCL) and inner plexiform layer (IPL) of RRMS patients compared to controls, with AUROC values of 0.82 and 0.78, respectively. Inter-eye asymmetry was also notable in these layers, particularly the GCL (AUROC = 0.75) and IRL (AUROC = 0.74). The CNN, utilizing GCL thickness and IPL inter-eye difference as inputs, achieved an accuracy of 0.87, sensitivity of 0.82, and specificity of 0.92.</p>\u0000 \u0000 <p><b>Conclusions:</b> The study demonstrates that neuroretinal thinning and inter-eye differences in specific retinal layers, measurable by the Posterior Pole protocol in OCT, can effectively discriminate between MS patients and healthy controls. The CNN developed shows high accuracy in MS diagnosis, supporting the potential of OCT and AI integration in clinical settings. Further research is needed to validate these findings across larger and more diverse populations.</p>\u0000 </section>\u0000 </div>","PeriodicalId":6915,"journal":{"name":"Acta Ophthalmologica","volume":"103 S284","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/10.1111/aos.17163","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
