Chalcosis

Chalcosis, also known as metal staining of the cornea, is a condition in which tiny particles of metal deposit in the cornea of the eye, leading to discoloration and potentially impairing vision. This condition is most commonly caused by exposure to certain types of metal, such as iron, copper, or gold, which can occur in certain occupational settings, or as a complication of certain medical procedures.

Symptoms of chalcosis include discoloration of the cornea, which can appear as a yellow, green, or brown stain. Additionally, patients may experience decreased vision, eye pain, redness, and tearing.

Diagnosis of chalcosis is typically made through a physical examination of the eye by an ophthalmologist. The doctor may use a slit-lamp examination, which uses a special microscope to examine the eye, or may use a special dye called fluorescein to highlight any discolorations.

Preventing chalcosis from occurring can be challenging, as the condition is often caused by unavoidable occupational or medical exposures. However, there are some steps that can be taken to reduce the risk of injury. These include wearing protective eyewear or goggles in certain occupational settings, and discussing potential risks with a healthcare provider before undergoing certain medical procedures.
