Despite differences in thickness and volume between the FH group and that without, the outer retinal bands, including the ellipsoid zone and external limiting membrane, were either attenuated or unidentifiable in the fovea and perifovea in both groups, owing to the rate of disease progression at an early age in CRB1-associated retinopathies, which impeded quantitative analysis [1]. Here, CRB1 is linked to retinal disorder.
