They frequently give important diagnostic clues to central nervous system disorders. Intracranial disease frequently causes visual disturbances because of destruction of or pressure upon some portion of the optic pathways. Cranial nerves III, IV, and VI, which control ocular movements, may be involved, and nerves V and VII are also intimately associated with ocular function.
