Table 2.
Maximum drusen diameter (μm) for each of 12 eyes, as determined on the SD OCT (NWE interpolation) and composite CFP drusen maps. For confluent drusen, the maximum length of contiguous drusen is reported (see Figure 4). The p-value reported is obtained using a paired Student's t-test. (SD = standard deviation)
