Quantifying retinal size and shape distortion in different ultra-widefield imaging systems.

ABSTRACT:

Objective

To quantitatively investigate the retinal size and shape distortion in different ultra-widefield (UWF) imaging systems.

Methods and analysis

We imaged the posterior segments of model eyes using Daytona, Mirante, CLARUS 500, VG2001, BMizar and TRC-NW8. We measured the scale bars of each grid and the compactness of each ring to quantify the size and shape distortion. The relationship between the relative size with eccentricity and axial length was analysed. The size and shape distortion were compared among different UWF systems.

Results

The size is positively associated with eccentricity (β=0.202-0.482; p<0.001) and negatively associated with axial length (β=-0.787 to -0.890; p<0.001) in all UWF systems. There is a significant difference in slopes across devic
