Corneal biomechanics in glaucoma – A review of the current concepts and practice

Abstract

Intraocular pressure (IOP) is currently the only modifiable risk factor in glaucoma. Since all our efforts are directed towards maintaining a stable IOP to halt glaucoma progression, proper understanding about the science behind IOP measurement and biomechanics of cornea becomes paramount. In this paper, we address the basics of corneal biomechanics, recent developments and its impact on glaucoma diagnosis and management. An extensive literature search was done using PubMed and Google Scholar with the search terms such as biomechanics, hysteresis, and glaucoma. Relevant articles published in English language were reviewed.
