Correlation Between Corneal and Scleral Pneumatonometry: An Alternative Method for Intraocular Pressure Measurement – Corrected Proof
Purpose: To evaluate scleral pneumatonometry as an alternative method for measuring intraocular pressure (IOP).Design: Prospective cross-sectional study.Methods: Adult subjects with healthy eyes were recruited from the Comprehensive Eye Service at the University of Illinois Eye and Ear Infirmary from August 2008 through February 2009. Study measurements included corneal pneumatonometry (IOPk), scleral pneumatonometry (IOPs), axial length (AL), spherical equivalent (SE), and central corneal thickness (CCT). Main outcome measures were scleral IOP and corneal IOP.Results: Analysis included a monocular data set from single eyes of 97 subjects (age: 18-82 years). IOPs was consistently higher than IOPk, and correlated positively with IOPk (r = (Read more...)
