Purpose of reviewHere, we provide an overview of Vogt-Koyanagi-Harada disease (VKH), including recent updates in our understanding of disease pathophysiology, classification and therapeutics.
Recent findingsAdvancements in bioinformatics, metabolomics and genomics investigations continue to illuminate VKH pathogenesis, and may provide insight into future therapeutic options. Multimodal imaging is indispensable in the initial evaluation of VKH, and is becoming increasingly important in understanding disease pathogenesis, as well as monitoring therapeutic response. Enhanced VKH classification criteria, released in 2021, provide standardized guidelines and terminology for clinical and research purposes.
The purposes of this study were to assess the reproducibility of a novel standardized technique for capturing corneal subbasal nerve plexus images with in vivo corneal confocal microscopy and to compare nerve metrics captured with this method in participants with dry eye and control participants.Methods: Cases and controls were recruited based on their International Statistical Classification of Diseases and Related Health Problems (ICD-10) diagnoses. Participants completed the following 3 ocular symptom questionnaires: the Ocular Surface Disease Index, Neuropathic Pain Symptom Inventory, and Dry Eye Questionnaire 5. A novel eye fixation-grid system was used to capture 30 standardized confocal microscopy images of the central cornea. Each participant was imaged twice by different operators. Seven quantitative nerve metrics were analyzed using automated software (ACCmetrics, Manchester, United Kingdom) for all 30 images and a 6-image subset.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
