Table 3. Geographic location study–Cell area as a function of distance from optic nerve head.

Comparison: Cell Area	Mean 1	Mean 2	Mean Diff.	SEM of diff.	n1	n2	q	DF	Significant?	Adjusted P Value
Macula versus Mid-Periphery	517.6	572.5	−54.91	75.5	4	4	1.029	9	No	0.7541
Macula versus Far-Periphery	517.6	1191	−673.6	75.5	4	4	12.62	9	Yes	<0.0001
Mid Periphery versus Far Periphery	572.5	1191	−618.7	75.5	4	4	11.59	9	Yes	<0.0001

1-way ANOVA with Tukey analysis of Cell Area. Geographic spots or locations were defined as in Figure 2A and Table 2. The data suggest that cells in the far periphery had larger cell areas than those in the macula and mid-periphery.
