Juvenile Cataract Morphology in 3 Siblings Not Yet Diagnosed with Cerebrotendinous Xanthomatosis
Purpose:
Cerebrotendinous xanthomatosis is a progressive neurodegenerative storage disease caused by recessive CYP27A1 mutations and is characterized by abnormal deposition of cholestanol and cholesterol in multiple tissues, including the lens and brain. Oral chenodeoxycholic acid is preventive and can be therapeutic, but is not used optimally because the condition typically is diagnosed late or not at all. When affected children demonstrate lens opacities, ophthalmologists have the unique potential to facilitate earlier diagnosis and treatment by recognizing the juvenile cataract phenotype. This study highlights the morphology of lens opacities in a (Read more...)
