Abstrakt
Homonymous hemianopia is a visual defect caused by various pathological processes of the central nervous system, particularly if located beyond the optic chiasm. In the first part of this chapter, we describe the physiological principles of cortical visual processing.
In the second part, we discuss the pathological physiology and etiopathogenesis of the disorders. Causes of homonymous defects include cerebral stroke (primarily), as well as neurodegeneration, demyelinization, hypoxia, trauma, tumors, and carbon monoxide intoxication.
