Eye Discharge (Eye Mucus ): Types, Causes and Treatment

Sometimes called rheum, eye discharge serves a protective function by removing potentially harmful waste products and debris from the tear film and the front surface of the eyes.

Eye discharge is the secretion of fluids or other substances, besides tears, from the eyes. The discharge from the eyes can make it difficult to open the eyelids if they have been closed for long periods, such as during sleep. This effect can be temporary or persistent.

Types of Eye Discharge

• Conjunctivitis or pink eye: Itchy, red eyes caused by viral conjunctivitis. Discharge may be green, white, or yellow. Caused by a virus, bacteria, or allergy.
• Bacterial conjunctivitis or other eye infections: Certain types of conjunctivitis require antibiotics. Causes pink, swollen, painful eyes and fever.
• Stye or chalazion: Blocked glands in the eyelids cause swelling or lumps.
• Eye Injury: Eye injuries, such as a scratched cornea, can cause swelling, itchy eyes, and thick discharge if they become infected.
• Blocked tear duct: Causes thick, sticky eye mucus and pain.
• Object in the eye: Contact lenses, eyelashes, or foreign objects can irritate eyes, causing wetness, mucus, and light sensitivity.

Causes of Eye Discharge

• Bacterial Conjunctivitis: A Bacterial eye infection causing pus and sticky eyelids, affecting one or both eyes.
• Viral Conjunctivitis: A viral infection causing pink, watery eyes, usually no pus, affecting both eyes.
• Normal Discharge: Small, cream-colored mucus in the eye corners, needing no treatment except cleaning.
• Lacrimal duct blockage: Common in newborns, leading to constant watery eyes and possible secondary infections.
• Foreign Objects in the Eye (severe): Sand or dirt particles can cause infection if not removed.
• Cellulitis of the eyelid (severe): Severe infection causing red, swollen, sensitive eyelids and eye closure.

Symptoms of Eye Discharge
