“…In a preliminary study as reported by Contestabile et al (2002) on 18 eyes of 13 patients with low-vision who underwent visual rehabilitation with a new instrument for biofeedback showed an increase in visual performances (Visual acuity, colour vision, automated perimetry, contrast sensitivity and flash VEP), related to a control group in which no treatment was performed. As found by Giorgi et al (2005) in one hundred and ten patients (179 eyes) with reduced visual acuity caused by different ocular disorders, who underwent visual rehabilitation with an instrument for biofeedback: improved biofeedback integrated system (Ibis), improved visual acuity in 130/179 eyes (72.62%).…”

“…Giorgi et al (2005), Contestabile et al (2002), Mezawa et al (1990) have proposed different visual rehabilitation techniques using biofeedback strategies starting from basic systems like accomotrack or IBIS devices, merging to more complex instruments as the visual pathfinder. Recently introduced techniques, such as microperimetry by SLO, as reported Fujii et al (2002) and Nilsson et al (2003), lead us to a better knowledge of the cognitive processes of rehabilitation and more serve as a diagnostic tool for the follow-up of AMD patients.…”

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.

“…In ophthalmology, various techniques of biofeedback, such as plain light stimulus,1 acoustic biofeedback,2 and structured light stimulus plus acoustic biofeedback3 have been applied to congenital nistagmus,4 amblyopia,5,6 macular disease,7 and emianopia8,9 and have proved to be efficacious in the improvement of visual function in these disorders. In 1993, Rauscher et al10 found that listening to Mozart music could improve the IQ (intelligence quotient) score of students, as opposed to listening to relaxation instructions or silence.…”

PurposeTo evaluate the usefulness of acoustic biofeedback by means of Mozart’s Sonata for Two Pianos in D Major K. 448 to maintain and/or restore visual performance in a patient with macular pucker and glaucoma.MethodsA 74-year-old patient with open angle glaucoma in both eyes and macular pucker in the right eye (RE) underwent visual rehabilitation with acoustic biofeedback by means of the MAIA™ Vision Training Module (Centervue, Padova, Italy) 10 minutes each eye once a week for 5 weeks. The patient was asked to move his eyes according to a sound which changed into Mozart’s Sonata for Two Pianos when the patient locked the fixation target.ResultsBest-corrected visual acuity improved in his right eye (RE) and was stable in the left eye (LE). Fixation stability improved in both eyes, and retinal sensitivity decreased in the RE and improved in the LE. The characteristic of the macular pucker did not change during the training as demonstrated with optical coherence tomography. The patient was very satisfied with the training, as demonstrated by a 25-item questionnaire (National Eye Institute – Visual Functioning Questionnaire, NEI-VFQ-25). The patient’s reading speed and the character size which he was able to read improved in his RE.ConclusionMusic could enhance synaptic plasticity and affect neural learning and fixation training by means of MAIA vision training. Therefore it can improve visual performance in patients with macular pucker, postpone the surgical time, and assure a better quality of life for the patient.

One hundred and ten patients (179 eyes) with reduced visual acuity caused by different ocular disorders underwent visual rehabilitation with an instrument for biofeedback: improved biofeedback integrated system (Ibis). One hundred and fourteen eyes had age-related macular degeneration, 39 eyes had myopic macular degeneration, and 26 eyes were affected by different ocular disorders. A placebo training was developed on 34 patients (47 eyes). Thirty-three eyes had age-related macular degeneration and 15 eyes had myopic macular degeneration. Visual acuity was found to be improved in 130/179 eyes (72.62%). Mean visual acuity was 0.24 before training and 0.36 at the last follow-up. A review of the literature and possible mechanisms are discussed.
