What metabolic disorder causes cataract?

Galactosemia is a metabolic disorder that can lead to cataracts. It results from the body's inability to properly metabolize galactose, a sugar found in milk and dairy products. Elevated levels of galactose can lead to the accumulation of galactose-1-phosphate, which can cause damage to the lens of the eye, increasing the risk of cataract formation. Early diagnosis and dietary management are crucial to prevent complications, including cataracts.
