Table 2. The mean choroidal thickness measurements of DME patients and healthy controls.

Choroidal thickness (μm)	DME (mean±SD)	Control (mean±SD)	P-value
Subfoveal	273.5±30.2	321.4±36.5	<0.001
Nasal, 1.5 mm	273.2±29.4	325.0±41.4	<0.001
Temporal, 1.5 mm	279.9±27.6	319.5±41.0	<0.001
Nasal, 3 mm	275.3±27.1	327. 6±36.8	<0.001
Temporal, 3 mm	277.5±28.4	322.4±40.7	<0.001

P<0.05 indicates statistically significance.
