The usefulness of CorvisST Tonometry and the Ocular Response Analyzer to assess the progression of glaucoma. [PDF]

Sci Rep, 2017
AbstractCorneal Visualization Scheimpflug Technology (CST) and Ocular Response Analyzer (ORA) measurements were carried out in 105 eyes of 69 patients with primary open-angle glaucoma. All patients had axial length (AL), central corneal thickness (CCT), intraocular pressure (IOP) with Goldmann applanation tonometry (GAT) and eight visual fields (VF)s ...

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

TNOA Journal of Ophthalmic Science and Research, 2020
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 ...

Ocular Response Analyzer versus Goldmann Applanation Tonometer for Measurement of Intra-Ocular Pressure

QJM: An International Journal of Medicine, 2021
Abstract Background Goldmann applanation tonometry (GAT) has been the gold standard for intraocular pressure(IOP) measurement ,since its appearance in clinical practice around 50 years ago.(1) In spite of being almost unchallenged, the last few years have become a sustained search for a new standard ...
