Cobalt intoxication is a rare cause of toxic opticopathy, and may be caused by metal
endoprostheses. Since its clinical appearance is unspecific and the incidence low,
diagnosis is challenging. Due to the dramatic consequences of delayed treatment, cobalt
intoxication should be considered as a rare differential diagnosis of bilateral loss
of vision in patients with appropriate history.
