Abstract
To analyse biofeedback training by microperimeter MP-1 (Nidek Technologies) on patients with Age Related Maculopathy (AMD). We enrolled 15 patients (10 female and 5 male) and examined total of 27 eyes with AMD. All the patient underwent 10 training sessions of 10 min for each eye, performed once a week using the MP-1 biofeedback examination. Statistical analysis was performed using Student’s t-test. p values less than 0.05 were considered statistically significant. All patients displayed an improvement in visual acuity, fixation behaviour, retinal sensitivity an reading speed. The mean character size value improved from 36.4 to 11.7; this result was statistically significant (p = 0.031). A biofeedback examination using the MP-1 microperimeter can help the brain to memorize the final fixation location by increasing attention modulation, thereby providing an efficient preferred retinal locus for visual tasks in patients with macular disease and central scotoma.
