摘要: Abstract Background Various instruments have been developed to measure aligning prism, the prism that eliminates a fixation disparity (associated heterophoria). This includes established Mallett near vision unit and recently Thomson Vision Toolbox on iPad. With no previous research investigating agreement between these instruments, practitioners may question if they can be used interchangeably. Methods 80 participants underwent testing with iPad test. Data were analysed in four ways investigate of two instruments. Results Many reported (horizontally 46.25%, vertically 82.5%), or non-significant 70%, 97.5%), both The revealed larger range results horizontally, 6Δ base out 15Δ in; produced vertically, 1Δ up 3.5Δ down. More required significant horizontally vertically. Wilcoxon signed rank analysis found difference was not statistically (p = 0.357 p = 0.236 vertically), but 95% limits clinically differences Conclusion Although measured are analysis, Bland & Altman approach shows them some cases unacceptable, therefore should Previous indicates performs reasonably well at detecting symptomatic individuals determining prismatic correction is likely helpful. Further determine performance test functions assess reproducibility
