Eyelid edema eyelid edema and bulbar conjunctival edema are common symptoms of nephritis patients, especially when getting up in the morning eyelid edema is most obvious. For more serious chronic nephritis, vision has decreased to varying degrees, and cotton wadding exudate, retinal hemorrhage, arterial spasm, etc. can also be seen in the fundus. Chronic liver disease, malnutrition, anemia, angioneurotic edema can also cause eye edema.
