Correlations between retinal thickness analyzer (RTA) and confocal scanning laser tomography (HRT) in optic disc analysis



Correlations between retinal thickness analyzer (RTA) and confocal scanning laser tomography (HRT) in optic disc analysis



Archivos de la Sociedad Espanola de Oftalmologia 79(1): 21-25



To determine if the measures obtained in an optic disc study using the retinal thickness analyzer (RTA) can be adequately correlated with values provided by the confocal scanning laser Heidelberg Retina Tomograph (HRT). We analyzed 20 eyes of 20 normal subjects. The contours of the optic disc were drawn by a single operator using both instruments. The data compared were the values of 10 variables denoted in the same way by each instrument and these provided information on disc and cup morphology. Of the 10 variables, only the following three showed clear correlation between the two instruments: maximum cup depth (r=0.926, p=0.001), mean cup depth (r=0.857, p=0.001) and cup shape measure (CSM, r=0.672, p=0.002). The correlation shown by the remaining variables ranged from 0.001 (cup area) and 0.488 (cup volume). The variables showing best correlation between instruments were those providing information on cup morphology. Operator subjectivity when drawing the disc contour using each device could account for the lower incidence of correlation of the other variables examined.
