Clinical manifestations of chalcosis includes: Kayser Fleischer rings: due to deposition of copper under peripheral pas of Descement's membrane. Sunflower cataract: due to deposition of copper under the posterior capsule of the lens. Deposition of golden plaques at the posterior pole of retina which reflects the light with a metallic sheen.
