normal	71.8 ±10.2	199.6±14.1	271.3±23.3	195.2±17.5
dystrophy	67.1 ±16.4	92.3 ±35.0	159.2±48.0	101.0±41.1
p-value	0.395	<0.001	<0.001	<0.001
95% CI of difference in means.	-19.9, 10.6	-137.7, -77.9	-154.8, -70.1	-130.4, -58.2
FD(95% CI)	-0.06(-0.28, 0.15 )	-0.54(-0.69, -0.39)	-0.41 (-0.57, -0.26)	-0.48(-0.67, -0.30)
Standardized deviation (95% CI)	-0.46 (-1.94 , 1.03 )	-7.64 (-9.76, - 5.52 )	-4.82 (-6.64, - 3.00 )	-5.39 (-7.45, - 3.32 )

Foveal averages are computed in the central 1.5-mm diameter area.

foveal IRL: foveal Inner retina layer

foveal ORL: foveal outer retina layer

foveal RT: foveal retinal thickness

cRT: Retinal thickness at the central point of fovea
