Pink eye, medically known as conjunctivitis, is a highly contagious and common eye condition characterized by inflammation or infection of the conjunctiva, the thin membrane covering the white part of the eyes and the inside of the eyelids. One of the most noticeable symptoms of pink eye is the presence of discharge, which can vary in color, consistency, and quantity depending on the underlying cause. Understanding the causes, symptoms, and relief options for pink eye discharge is essential for effective management and treatment.
The causes of pink eye discharge can be broadly categorized into viral, bacterial, and allergic conjunctivitis. Viral conjunctivitis is the most common type and is usually caused by viruses such as adenovirus, coronavirus, and enterovirus. Bacterial conjunctivitis, on the other hand, is caused by bacteria like Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. Allergic conjunctivitis occurs when the eyes come into contact with allergens like pollen, dust mites, or pet dander.
Causes of Pink Eye Discharge
The type and severity of pink eye discharge depend on the underlying cause. In viral conjunctivitis, the discharge is usually watery and clear, while in bacterial conjunctivitis, it is thick and yellow or greenish in color. Allergic conjunctivitis typically produces a stringy, white or yellowish discharge.
