Interocular Asymmetry of Foveal Thickness in Parkinson Disease

Table 2

Individual subjects outside their group’s retinal thickness mean IOD at 1 control SD at each radial distance (mm). It is evident that the most false positives (controls) were at 1 and 1.25 mm. The highest percentage of correctly identified patients was at 0.5 and 0.75 and to a lesser extent at 1 mm and 1.75 perifoveolar distance (see also Table 5).

	0.25 (mm)	0.5 (mm)	0.75 (mm)	1.0 (mm)	1.25 (mm)	1.5 (mm)	1.75 (mm)	2.0 (mm)
Number of Ctrl	2	1	0	1	2	3	1	1
Number of PD	0	4	5	3	2	3	4	1
Percentage of 23 PD patients	0	17.4	21.7	13	8.7	13	17	4.3
Percentage of 18 controls	11.1	5.5	0	5.5	11.1	16.7	5.5	5.5
