Corneal Biomechanical Changes Induced by Chronic Elevated Intraocular Pressure: Implications for Glaucoma Pathogenesis and Management

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
The significance and contributions of corneal biomechanics in the study of chronic elevated intraocular pressure are multifaceted. Not only does it enhance our understanding of how chronic elevated intraocular pressure affects corneal structure and function, but it also offers new perspectives for the early diagnosis of glaucoma. Analysis of the cornea’
