Quinine-/Quinidine-induced persisting perception disorder

Quinine is a natural white crystalline alkaloid having antipyretic (fever-reducing), antimalarial, analgesic (painkilling), and anti-inflammatory properties and a bitter taste. It is a stereoisomer of quinidine. Fisher (1981) reported visual disturbances associated with quinidine and quinine in 5 patients, including a variety of transitory visual symptoms in 4 patients and persistent photophobia in 1 patient.
