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.

Fixation stability
Achievement of a stable fixation, defined according to Fuji classification (Stable: if more than 75% of the fixation points are inside a 2° diameter circle that has as a center the centroid of all fixation points) and the Bivariate Contour Ellipse Area, were selected as primary outcomes.
Time frame: 6 months
Reading speed
Achievement of good reading speed: higher than 87 words per minutes was defined as our secondary outcome. Parameters for words per minutes are referred to visually impaired functional reading reported in literature
