Abstract
Background: Accurate evaluation of diplopia during bedside physical examination is challenging. We developed
a new computerized red glass test (CRT) to detect, localize, and quantify diplopia and investigated whether the
CRT is useful and feasible.
Methods: During the CRT, a white dot randomly appears on a monitor. Because a red glass is applied on the
right eye, a patient can see one white dot and one red dot when diplopia is present. We defined the degree of
diplopia as the direct distance of the two points with the largest deviation and compared the degree with the
Hess score and Hess area ratio.
Results: We prospectively enrolled 14 patients with binocular diplopia. Test–retest reliability of the CRT was
excellent (overall intraclass correlation coefficient = 0.948, 95% CI 0.939–0.956). The degree of diplopia in the CRT
was well correlated with both the Hess score (r = 0.719, p = 0.005) and the Hess area ratio (r = −0.620, p = 0.018).
Conclusions: The CRT can easily detect the presence of diplopia and provided the quantitative values of the
degree of diplopia. The CRT was useful and feasible for improving routine bedside examination.
