    Abstract:
    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.
