Scotopic Microperimetry in the Early Diagnosis of Age-Related Macular Degeneration: Preliminary Study

Table 2

Data subjects and retinal sensitivity evaluated through mesopic (MP-1) and scotopic microperimetry (MP-1S) map created using a pattern of 39 points. The retinal response, evaluated through mesopic microperimetry, was compromised in both groups. In fact, the average value was 19.07 ± 0.21 dB in the group with hard drusen and 19.17 ± 0.99 dB in the group without fundus alterations (not statistically significant). Instead, a marked reduction in scotopic retinal response was found in patients with hard drusen 5.20 ± 1.18 dB versus control group 7.70 ± 0.24 dB (statistically significant, < 0.003).
