Anterior subcapsular cataract Sunflower cataract 2024-03-30T13:20:05Z Sunflower cataract (SC) is a type of anterior subcapsular cataract almost only seen in Wilson disease, an autosomal-recessive condition with a defect in the metabolism of copper leading to accumulation of copper in the liver and basal ganglia. SC consists of a thin, centralized opacification that is located directly under the anterior capsule and encompasses between one-third and one-half of the anterior lens pole surface area. In all cases, the central opacification is surrounded by additional, secondary opacifications arranged in ray-like structures around it. This pattern is said to resemble a sunflower, with a large central disk surrounded by petals.
