What Is Eye Drainage?

Eye drainage refers to the discharge of tears, mucus or pus from the eye. A small amount of crust in the corners of the eye after sleep is normal as the eyes clean themselves. However, excessive or abnormal discharge that is yellow, green, sticky or foamy may indicate inflammation or infection. Abnormal drainage is often accompanied by pain, itching, redness, swelling and vision changes.

Causes of Eye Drainage

Normal discharge occurs as the eye clears debris and mucus. Excessive or abnormal discharge can result from conjunctivitis (pink eye) caused by bacteria, viruses or allergies; keratitis (corneal inflammation often linked to contact lens overuse); blepharitis (eyelid inflammation); styes; dacryocystitis (tear duct infection); and dry eye disease. Each condition produces characteristic discharge and requires specific treatment.

Symptoms of Concern

Abnormal eye drainage may be yellow or green, thick or foamy and accompanied by crusting of the lashes. Other symptoms include eye pain, itching, redness, swollen eyelids, a gritty sensation, blurred vision and light sensitivity. Fever or general illness may accompany infections. Contact a doctor if these symptoms appear.

When to Seek Medical Help

See an eye care provider if you have abnormal discharge, especially if it comes with pain, swelling or vision changes. Some conditions like bacterial conjunctivitis require antibiotics. Persistent discharge may indicate a blocked tear duct or chronic condition that needs medical treatment.

Treatment and Home Care

Treatment depends on the cause. Doctors may prescribe antibiotic, antiviral, antifungal or antiparasitic medications. Allergic discharge may improve with antihistamines. Home remedies include using warm or cool compresses, artificial tears and keeping contact lenses clean. Avoid sharing towels or eye makeup and maintain good hygiene to prevent spread.
