| Popis | Visual information is transfer via optic tract and processed by an interaction of the striate cortex with visual associative areas. These areas evaluate different properties of the signal and contribute to an overall perception of the visual environment. Lesions of associative cortices in humans cause disorders that are termed central visual disorders and often accompany homonymous visual field defects. An understanding functions of these areas is crucial, as many of these patients will first contact an ophthalmologist. Usually vague complaints are referred that may be difficult to specifically define. This chapter gives an overview of central visual disorders that can be found in patients with homonymous visual field defects and the principles of neurological and neuropsychological examination in these patients. |
