Evaluating Therapeutic and Chemical Toxicity Using Organ-Cultured Porcine Corneas and Epithelial Wound Healing.
J Vis Exp
January 2025
Departments of Ophthalmology and Anatomy and Cell Biology, Kresge Eye Institute, Wayne State University School of Medicine;
Due to its anatomical and physiological similarities to the human eye, the porcine eye serves as a robust model for biomedical research and ocular toxicity assessment. An air/liquid corneal culture system using porcine eyes was developed, and ex vivo epithelial wound healing was utilized as a critical parameter for these studies. Fresh pig corneas were processed for organ culture, with or without epithelial wounding.

STZ eyetrial at the Centre for Ophthalmology, Tuebingen, Germany.
Purpose: Reports of gene therapy-associated retinal atrophies and inflammation have highlighted the importance of preclinical safety assessments of adeno-associated virus (AAV) vector systems. We evaluated in nonhuman primates (NHPs) the ocular safety and toxicology of a novel AAV gene therapy targeting retinitis pigmentosa caused by mutations in PDE6A, which has since been used in a phase I/II clinical trial (NCT04611503).
Methods: A total of 34 healthy cynomolgus animals (Macaca fascicularis) were treated with subretinal injections of rAAV.
Mitochondria-localized dinuclear iridium(III) complexes for two-photon photodynamic therapy.

MOE Key Laboratory of Bioinorganic and Synthetic Chemistry, Guangdong Basic Research Center of Excellence for Functional Molecular Engineering, School of Chemistry, Sun Yat-sen University, Guangzhou, 510275, P. R. China.
Photodynamic therapy (PDT), as a non-invasive cancer treatment, offers significant advantages including high temporal-spatial selectivity, minimal surgical intervention, and low toxicity, thereby garnering considerable research interest from across the world. In this study, we have developed a series of dinuclear cyclometalated Ir(III) complexes as potential two-photon photodynamic anticancer agents. These Ir(III) complexes demonstrate significant two-photon absorption (2PA) cross-sections ( = 66-166 GM) and specifically target mitochondria.

Department of Ophthalmology and Visual Science, University of Chicago, Chicago, IL, United States.
Introduction: To report a series of patients who developed ocular surface disease related to tisotumab vedotin-tftv (TV), an antibody-drug conjugate (ADC) approved for the treatment of recurrent or metastatic cervical cancer.
Methods: This was a multicenter retrospective chart review study of patients who developed ocular surface disease related to TV between April 1st, 2022 to August 31st, 2023.
Results: Five patients were identified who developed ocular surface disease while on TV.
Ocular inoculation of toad venom: toxic cataract and proteomic profiling.

Eye Center of the 2nd Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, China.
Purpose: To report a singular case of cataract caused by toad venom inoculation and to scrutinize the pathological mechanisms through proteomic sequencing of the lens specimen.
Methods: A young Chinese male presented with progressively deteriorating vision in his right eye subsequent to a history of toad venom inoculation. He was diagnosed with a toxic cataract, and underwent phacoemulsification cataract surgery.
