Effect of Altered Retinal Cones/Opsins on Refractive Development under Monochromatic Lights in Guinea Pigs

Table 1

The densities of S-cones and M-cones in the different groups (mean ± SD, mm²).

Cell	Area	SL group		ML group		WL group
		Mean ± SD		Mean ± SD		Mean ± SD
S-cone	Dorsal	1476 ± 317.5	0.014	592 ± 105.8	0.018	887.7 ± 90.2
