Wilson’s Disease: Ophthalmic Manifestations¶
Jonathan A. Barnett
-
The two classic ophthalmic manifestations of Wilson’s disease are the “Kayser-Fleischer ring” (copper deposition around the corneal limbus) and the “Sunflower cataract” (copper deposition in the lens).
-
Wilson’s disease rarely affects vision (unless the sunflower cataract is very advanced).
-
Unless the disease is very advanced/has been present for years, it is impossible for one to detect subtle copper deposition in the cornea, iridocorneal angle, or lens without an office-based slit lamp exam and gonioscopy (only available in the outpatient setting).
-
Furthermore, the presence or absence of a Kayser-Fleischer ring does not rule in or rule out the disease
-
Testing for decreased ceruloplasmin, urinary copper levels, and genetic testing are more effective diagnostic methods.

-
If concerned about the visual impact of a developing sunflower cataract, an outpatient ophthalmology referral is appropriate.
