Table 1.
Participant details for all seven individuals with macular degeneration we have tested including two (MD1 and MD2) whose data we reported previously (Baker et al., 2005). MDs 1-5 all had no measurable foveal function whereas MDs 6-7 both had some degree of spared foveal function. JMD is Juvenile Macular Degeneration. AMD is Age-related Macular Degeneration. An asterisk denotes the tested eye (no asterisk indicates that the participant was tested binocularly).
