The Distribution of the Photoreceptor Outer Segment Length in a Healthy Population

Table 1

The demographic characteristics, the mean spherical equivalent, and the photoreceptor outer segment length values for each group are shown.

Age (years; ±SD)	13.03 ± 3.85	30.50 ± 5.52	51.58 ± 5.56
Gender (female %)	51%	56%	52%
Spherical equivalent (mean)	−0.005 ± 0.60	−0.14 ± 0.47	0.27 ± 0.42
Photoreceptor outer segment (PROS) length (mean; μm)	53.70 ± 3.18	52.14 ± 3.64	52.20 ± 3.95
