Psicofísica clínica: aplica？？o de metodologia psicofísica no auxílio de diagnósticos. Descri？？o de método

the psychophysics applied to the clinic with humans may provide alternative tools to assist access to objective and quantifiable internal conditions of the patient, which could only be obtained otherwise, through their stories and descriptions. an example of this partnership and implementation of psychophysics is the commercial unit c-quant (oculus optikger？te, germany), whose psychophysical method of access to the value of light scattering in the retina was developed by the group of dutch researchers led by prof. dr. thomas van den berg, netherland's institute of neuroscience (nin). access to the amount of light scattering in the retina is useful for the diagnosis of various eye diseases such as cataracts. in this article the psychophysical method in this unit (comparison of compensation) is described.
