Description
Summary:To assess the precision and reliability of a novel computerized heterophoria test (CHT). One hundred and three subjects aged 20 to 48 (27.37 ± 5.15) were recruited from Wenzhou Medical University. All subjects with corrected spectacles were examined with CHT and a prism-neutralized objective cover test (POCT) in a randomized order. They were then re-examined with CHT within 1 week. Their heterophoria was measured at three different distances (3 m, 0.77 m and 0.4 m); the average was recorded after three consecutive measurements. Inter-examiner repeatability, intra-examiner repeatability of CHT and agreement between CHT and POCT were evaluated. There was no significant difference among repeated measurements using CHT (all  > 0.05). The difference between POCT and CHT was statistically significant at three distances (all
