BAGOLINI's RED FILTER BAR

is used to investigate the depth of suppression in patients with amblyopia - it consists of a series of red filters of increasing density from very pale to very dark - this decreases the illumination in front of the fixating eye to induce fixation with the deviating eye and therefore diplopia - the patient looks at a spot light about 30 cm away in the primary position and the Bagolini's bar is introduced before the fixating eye starting with the palest filter - the filter strength is increased until the patient sees one red and one white light as a result of diplopia - the strength of the filter at which this occurs indicates the density of suppression - supplied in a 18.31x1.3x0.2 in wooden case
