What causes cloudy eyes

Many friends are at a loss when their eyeballs become cloudy. Both external and internal factors may cause this situation. If the external environment is dusty, it will cause cloudiness in the eyes over a long period of time. In addition, staying up late frequently and having an unstable work and rest schedule are also bad for the eyes.

1. Hemolytic jaundice: Any disease that can cause massive destruction of red blood cells and produce hemolysis can cause hemolytic jaundice. Common diseases fall into two categories.

(1) Congenital hemolytic anemia: such as thalassemia (hemoglobinopathy) and hereditary spherocytosis.

(2) Acquired hemolytic anemia: such as autoimmune hemolytic anemia, hereditary glucose-6-phosphate dehydrogenase deficiency (favism), hemolytic anemia after heterotypic blood transfusion, neonatal hemolytic anemia, malignant malaria, primaquine and other drugs, snake venom, mushroom poisoning, paroxysmal nocturnal hemoglobinuria, etc.

2. Hepatocellular jaundice: Various liver diseases, such as viral hepatitis, toxic hepatitis, drug-induced liver disease, various types of cirrhosis, primary and secondary liver cancer, sepsis and leptospirosis, can cause jaundice due to diffuse damage to hepatocytes.

3. Obstructive jaundice (cholestatic jaundice): According to the site of obstruction, it can be divided into extrahepatic bile duct obstruction and intrahepatic bile duct obstruction.

(1) Common diseases that cause extrahepatic bile duct obstruction include common bile duct stones, stenosis, inflammatory edema, ascariasis, tumors, and congenital biliary atresia. Common diseases or causes that cause extrahepatic compression and lead to common bile duct obstruction include pancreatic head cancer, chronic pancreatitis with enlarged pancreatic head, ampulla of Vater cancer, common bile duct cancer, liver cancer, and enlarged lymph nodes in the porta hepatis or around the common bile duct (cancer metastasis).

(2) Intrahepatic bile duct obstruction can be divided into intrahepatic obstructive cholestasis and intrahepatic cholestasis. The former is common in intrahepatic bile duct sludge stones, cancer thrombi (mostly liver cancer), Clonorchiasis, etc.; the latter is common in capillary cholangiocarcinoma viral hepatitis, drug-induced cholestasis (such as chlorpromazine, methyltestosterone, oral contraceptives, etc.), bacterial sepsis, recurrent jaundice during pregnancy, primary biliary cirrhosis and a few cases after heart or abdominal surgery.
