Comprehensive clinical imaging, histopathological analysis and liquid biopsy-based surveillance of human uveal melanoma in a prolonged rabbit xenograft model.

Uveal melanoma is the most common intraocular tumor in adults. Our group has previously developed a human uveal melanoma animal model; however, adverse effects caused by the immunosuppressive agent, cyclosporine A, prevented animals from surviving more than 12 weeks. In this study, we tested multiple cyclosporine A doses over an extended disease course up to 20 weeks, providing complete clinical imaging of intraocular tumors, histopathological analysis and liquid biopsy biomarker analysis.

Histopathological analysis of residual lens cells in capsular opacities after cataract surgery using objective software.

Purpose: Remnant lens epithelial cells (LECs) within the capsular bag (CB) undergo epithelial-to-mesenchymal transition (EMT) and acquire a myofibroblast phenotype, depositing extracellular matrix (ECM) components, leading to posterior capsular opacification (PCO). This study histopathologically analyzes the LEC-to-myofibroblast transition and de novo ECM component deposition (i.e.

Circulating tumor DNA tracking through driver mutations as a liquid biopsy-based biomarker for uveal melanoma.

Background: Uveal melanoma (UM) is the most common intraocular tumor in adults. Despite good primary tumor control, up to 50% of patients develop metastasis, which is lethal. UM often presents asymptomatically and is usually diagnosed by clinical examination and imaging, making it one of the few cancer types diagnosed without a biopsy.

Removing Subjective Post-Mortem Grading from Posterior Capsular Opacification: A New Automated Detector Opacification Software, ADOS.

Unlabelled: Purpose/aim: Posterior capsular opacification (PCO) is the leading complication following cataract surgery. However, PCO grading methods vary between studies and rely on subjective scoring methods; hence, they are prone to error. Therefore, software that reduces subjectivity and enhances reproducibility is needed.
