MP-3 Biofeedback Training and Central Vision Loss

The objectives of this investigation are: * evaluate the results of rehabilitation treatment using photostimulation with a structured stimulus in two different samples of low vision subjects with central vision loss who will be subjected to biofeedback at the MP3 microperimeter with different timing; * compare the effectiveness of the rehabilitation treatments in the two groups to provide useful indications for proposing standardisation of the rehabilitation pathway focusing on photostimulation in subjects with central vision loss.
