Answer:
Chalcosis
Introduction Symptoms Causes Diagnosis Management Complications Prevention
Chalcosis or chalcosis bulbi refers to mild ocular inflammation due to an intraocular foreign body containing copper between about 70 to 85%. Chalcosis results in deposition of copper on lens capsule (sunflower cataract), Descemet’s membrane (Kayser- Fleischer ring), iris (green discolouration), sluggish pupillary response, vitreous degeneration and liquefaction, yellow retinal plaques and degeneration.
The intensity of inflammatory response due to copper containing foreign body depends upon the copper content. It may lead to
Severe endophthalmitis if copper content is more than 85%
Chalcosis if less than 85%
Foreign body containing less than 70% is relatively inert in the eye.
Chalcosis may be acute or chronic.
