Abstract EN
Purpose.
To assess the repeatability of the Galilei dual Scheimpflug analyzer (GDSA) in anterior segment examination.
Methods.
Fifty-two eyes from 52 healthy volunteers were prospectively and consecutively recruited.
Anatomic, axial, refractive, and instantaneous parameters were measured with GDSA to provide a complete characterization of the anterior segment.
Repeatability was assessed calculating intraclass correlation coefficient (ICC), and coefficient of variation (COV).
Results.
Correlation among repeated measurements showed almost perfect reliability (ICC > 0.81) for all parameters except thinnest central corneal thickness (CCT) (0.78), corneal thickness average out (0.79), and posterior axial curvature average out (0.60).
Repeatability was excellent (COV < 10%) for all parameters except anterior chamber volume and, superior iridocorneal angle and eccentricities.
In these last three parameters, repeatability limits were excessively high compared to the mean.
Conclusions.
GDSA in healthy young persons had an almost perfect correlation in measuring anatomic, axial, instantaneous, and refractive parameters with greater variability for peripheral terms.
Repeatability of anatomical parameters like pachymetry, anterior chamber, or iridocorneal angle and eccentricity were limited.
In healthy young persons, the other evaluated parameters had very good repeatability and their limits of agreement showed excellent clinical results for this device.
