The aim of the present study is to compare intraocular pressure (IOP) values assessed with Ocular Response Analyzer to the classical gold standard of IOP measurement, to Goldmann applanation tonometry by mucopolysacchyridosis-, Fabry-patients and healthy controls. We want to investigate biomechanical characteristics of the cornea and their influence on the IOP-measurements.
Corneal-Compensated Intraocular Pressure, Corneal Hysteresis and Corneal Resistance Factor Measurements Performed With the Ocular Response Analyzer and Their Correlation to Conventional Goldmann Applanation Tonometry.
