A cataract caused by excessive amount of copper in the eye. It appears as small yellowish-brown opacities in the subcapsular cortex of the lens and pupillary zone with petal-like spokes that extend towards the equator. It may be due to an intraocular foreign body containing copper, or from eyedrops that contain copper sulfate, or as part of Wilson' s disease. Management consists mainly of removal of the foreign body. Syn. sunflower cataract.
