Fig. (2) Changes in visual function after the microcurrent therapy at 4 weeks. Top: The averaged Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity score significantly improved from 29.5±5.1 to 31.8±5.0 (mean±SE, P=0.0407) in wet-type age-related macular degeneration (ARMD) patients and in dry-type ARMD patients (from 39.8±4.7 to 42.9±4.9, P=0.0401). Bottom: The averaged mean deviation of the automated perimetry improved from -13.3±3.1 dB to -12.4±3.1 dB after treatment (mean±SE, P=0.0247) in wet-type ARMD patients while in dry-type ARMD patients, it changed from -9.3±3.2 dB to -9.3±2.8 dB (P>0.05). The ‘N.S.’ indicates ‘not significant’.
