What corneal finding targets Bowman's layer and is secondary to gout?

Band keratopathy is characterized by a grayish-white deposit of calcium in the Bowman's layer of the cornea. This condition is often associated with metabolic disorders, such as gout, where there is increased serum uric acid leading to calcium deposition. The deposits appear in a band shape and can affect vision by obscuring the corneal transparency.

In the context of gout, the elevation in uric acid results in findings like band keratopathy due to its role in altering the calcium metabolism in the cornea. This distinct corneal finding is thus closely linked to the systemic effects seen in gout, affecting the cornea specifically at Bowman's layer.

Other choices like pterygium, keratoconus, and corneal dystrophies represent different pathologies or mechanisms that do not specifically involve Bowman's layer as related to gout. For example, pterygium is a growth of conjunctival tissue over the cornea, keratoconus involves the thinning and conical shape of the cornea, and corneal dystrophies represent a group of genetic conditions that affect the corneal stroma rather than being secondary to metabolic issues like gout.
