Chrysiasis of the cornea occurs due to medication for which condition?

Chrysiasis of the cornea is a condition characterized by a gold deposition within the corneal tissue, which typically arises as a side effect of gold therapy. Gold compounds have been used primarily in the treatment of rheumatoid arthritis, particularly in patients who have not responded adequately to other forms of medication. This therapy can lead to various ocular manifestations, including chrysiasis.

While hypertension, diabetes, and cancer treatments can also have ocular side effects, they do not specifically lead to gold deposition in the cornea. Therefore, the association of chrysiasis with the use of gold therapy in rheumatoid arthritis distinguishes this condition and makes it the correct choice in this context. Understanding the medication's mechanism and its implications for ocular health is crucial for optometrists in evaluating and managing such conditions.
