New trends in visual rehabilitation with MP-1 microperimeter biofeedback: optic neural dysfunction.

New trends in visual rehabilitation with MP-1 microperimeter biofeedback: optic neural dysfunction. Funct Neurol. 2013 Oct-Dec;28(4):285-91 Authors: Verboschi F, Domanico D, Nebbioso M, Corradetti G, Zaccaria Scalinci S, Vingolo EM Abstract The aim of this study was to evaluate the efficacy of visual rehabilitation with MP-1 microperimeter biofeedback in advanced optic neural dysfunction due to glaucoma, and to precisely characterize fixation stability and location in affected patients. Ten patients (18 eyes) with advanced glaucoma were submitted to a rehabilitation protocol that consisted of: a 25-item questionnaire (National Eye Institute Visual Functioning Que stionnaire); measurement of visual acuity; a reading speed test; microperimetry with fixation study, retinal sensitivity and the bivariate contour ellipse area (BCEA). The rehabilitation program consisted of 10 training sessions of 10 minutes per eye performed over a period of one week and was repeated at four months, eight months, and one year. Statistical analysis was performed using the Student's t-test and Spearman correlation; p values less than 0.05 were considered statistically significant. In 13 eyes fixation changed from unstable to relatively unstable while its location changed from predominantly eccentric to predominantly central. In five eyes, fixation changed from relatively unstable to stable with a change of location from poor central fixation to predominantly...
