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. |
