Ophthalmia after pregnancy is commonly associated with gestational hypertension, a symptom of high blood pressure caused by pregnancy. Blurred eyes are mainly caused by the leakage of blood vessels in the fundus of the eye, which leads to retinal edema and decreased visual function. Gestational hypertension is mainly due to the spasm of small arteries throughout the body, which can cause narrowing of the lumen and increased peripheral resistance, as well as increased permeability due to damage to the endothelial cells of blood vessels, resulting in leakage of body fluids and proteins. In addition to ocular manifestations, patients with gestational hypertension may also show various systemic symptoms such as proteinuria and edema, and even damage to various organs and tissues throughout the body due to ischemia and hypoxia, so pregnant women with ophthalmology and obstetrics and gynecology should seek further treatment in a timely manner.
