Abstract
Pupillary disturbances due to toxic effects usually affect both eyes equally. Anisocoria is rare. The most common disturbance is mydriasis, accompanied by a loss or reduction of the phasic light reflex and an impairment of accommodation (Table 9). When an anticholinergic effect occurs, both the tonic and phasic light reflexes will be disturbed to an equal degree. With an adrenergic effect, the tonic light reflex will be disturbed to a relatively greater degree. With toxic damage to the afferent pupillary pathway (e.g., the optic nerve or retina), all the light reflexes will be impaired to some degree, with amaurotic pupillary paralysis representing the extreme case.
