METHODS: An observational study of 100 patients with glaucoma or ocular hypertension. All had a comprehensive ophthalmic examination and standard automated perimetry. IOP was assessed by GAT, Icare HOME and Ocular Response Analyzer, which was also used to assess corneal hysteresis (CH) and corneal resistance factor (CRF). Central corneal thickness (CCT) was recorded. RESULTS: Mean ({\textpm}SD) IOP measurements were 14.3{\textpm}3.9 and 11.7{\textpm}4.7 mm Hg using GAT and Icare HOME, respectively. Average CCT, CRF, and CH were 534.5{\textpm}37.3 μm, 9.0{\textpm}1.7 mm Hg, and 9.4{\textpm}1.5 mm Hg, respectively. The mean difference between Icare HOME and GAT was -2.66{\textpm}3.13 mm Hg, with 95\% limits of agreement of -8.80 to 3.48 mm Hg, however, there was evidence of proportional bias. There was negative correlation between IOP and CH [5.17 mm Hg higher Icare HOME IOP (P=0.041, R=0.029) and 7.23 mm Hg higher GAT IOP (P=0.008, R=0.080) for each 10 mm Hg lower CH], whereas thinner CCT was significantly associated with lower IOP (P, issn = {1536-481X}, doi = {10.1097/IJG.0000000000000948}, author = {Brown, Lyndsay and Foulsham, William and Pronin, Savva and Tatham, Andrew J} }
