The clinical and SPECT studies of photic stimulation therapy in patients with homonymous hemianopia / 中国康复理论与实践

ABSTRACT

@#Comparison of rCBF SPECT imaging and clinical visual function of 12 cases with complete homonymous hemianopia (CHH) were taken before and after a course of oriented dynamic color photic stimulation (ODCPS ). It was suggested that ODCPS in patients with CHH was an effective met hod for increasing visual field and improving visual function. Cerebral metabolic patterns of increasing rCBF reflected the mechanism of ODCPS effecting the patients with CHH. The rgtinal- midbrain-occipital visual path way may play an important role in mediating the increase of visual field and restoration of visual function.
