Chrysiasis of the cornea is associated with medication used to treat which condition?

Chrysiasis of the cornea is a phenomenon associated with the use of certain medications, particularly gold compounds, which are primarily used in the treatment of rheumatoid arthritis. The condition manifests as a characteristic golden or yellow-brown discoloration of the cornea due to the deposition of gold particles. This side effect is notable in patients undergoing long-term therapy with gold salts, which were historically important in managing rheumatoid arthritis before the advent of newer therapies.

The other conditions listed do not typically involve treatments associated with chrysiasis. Cancer treatments may include a variety of medications, but they do not generally lead to this specific corneal discoloration. Similarly, diabetes management and hypertension treatment involve different classes of medications that do not have any known association with the deposition of gold in the cornea. Thus, the connection between chrysiasis and rheumatoid arthritis therapy makes this the correct choice.
