Metabolic cataract

Metabolic cataract is related to the metabolism of the lens. Due to the increase in blood glucose and the increase in the glucose content of the lens, the activity of aldose-reducing plum is increased. Glucose is converted into sorbus. Sorbitol accumulates in the lens and increases the osmotic pressure. The lens absorbs water. The formation of fibrous swelling and degeneration eventually produces turbidity. Many systemic diseases, especially endocrine disorders, are often combined with different types of cataracts, that is, metabolic cataract. Cataract formation due to abnormal biochemical conditions in the environment is more common in cases of congenital metabolic abnormalities. Therefore, the understanding of cataracts related to metabolic diseases is of great significance not only for ophthalmology, but also for clinical evidence and differential diagnosis.
