Patients with swollen corners of the eyes may also be caused by bad habits, and may also be caused by eye infections, eye allergies and systemic diseases. 1. Bad habits: If patients stay up late for a long time or cry for a long time, it may lead to swelling of the inner corners of both eyes, and patients may also experience discomfort such as dry eyes and soreness. 2. Blepharitis: If the patient’s eyes have acute suppurative inflammatory infections, such as blepharitis, it can lead to localized congestion or swelling of the eyelids, and the patient can also experience eyelid pain, eye secretion and other uncomfortable symptoms. 3. Kidney disease: patients with kidney disease such as nephrotic syndrome may have swollen eyelids and lower limb edema due to kidney function impairment. 4. Allergic factors: If allergic patients are exposed to cosmetics, skin care products and other allergens, causing the release of allergic transmitters in local tissues, it can lead to eyelid swelling. It is recommended that patients with significant eyelid swelling consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
