Eye congestion is caused by a variety of reasons that lead to abnormal blood flow or rupture of small arteries in the eye, common causes may include high blood pressure, resulting in vitreous degeneration of the optic nerve capillaries leading to their sclerosis or rupture and hemorrhage; diabetes mellitus, long-term hyperglycemia causing degeneration of retinal arteries, brittleness increases and leads to blood flow disorders; late night, poor rest can also lead to eye congestion. Rosuvastatin is relatively safe and adverse reactions are rare, generally liver and kidney function is impaired, muscle pain and so on.
