Objective Virtual reality(VR)technology is closely related to eye vision.With the development and progress of hardware and software equipment,VR has been applied widely in the field of ophthalmology.This article describes the application of VR technology in the clinical research and ophthalmology education,reviews the current research results and advantages of this new technology,including the new curative effect in amblyopia/strabismus,myopia and glaucoma,as well as research on the technology's application in cataract surgery training and ophthalmology education.The article also discusses the dangers and difficulties of VR application and predicts its future application trend.In view of the shortcomings of VR in current research applications,the paper discusses and looks forward to provide powerful strategies for amblyopia,myopia and other ophthalmic diseases and clinical research.

Lipocalin-2 (LCN2), a member of the human lipocalin family, has been demonstrated to be closely associated with diabetes, cardiovascular diseases, and renal disorders. Recent studies have indicated that LCN2 plays a significant regulatory role in the pathogenesis and progression of various neurological diseases by mediating pathways such as inflammation, oxidative stress, and ferroptosis. This article reviews the research advancements on the mechanism of LCN2 in neurological disorders, including cerebrovascular diseases, cognitive impairment disorders, Parkinson's disease, depression, and anxiety disorders, aiming to enhance clinical understanding.
