Conjunctivitis (Pink Eye) can be noticed if there is a red eye. It is caused by infection, irritation, or a blocked tear duct. When caused by an infection, neonatal conjunctivitis can be very serious.

The baby will show symptoms like pink or red colour in the white of the eye(s), swelling of the conjunctiva (the thin layer that lines the white part of the eye and the inside of the eyelid) and/or eyelids, increased tear production, itching, irritation, and/or burning, discharge (pus or mucus), crusting of eyelids or lashes, especially in the morning.

People often call conjunctivitis “pink eye” because it can cause the white of the eye to take on a pink or red colour. Symptoms of pink eye can vary but typically include redness or swelling of the white of the eye.

Types of Conjunctivitis

Mild bacterial conjunctivitis may get better without antibiotic treatment and without causing any complications. It often improves in 2 to 5 days without treatment but can take 2 weeks to go away completely. Your doctor may prescribe an antibiotic, usually given topically as eye drops or ointment, for bacterial conjunctivitis if the condition gets worse.

Most cases of viral conjunctivitis are mild. The infection will usually clear up in 7 to 14 days without treatment and without any long-term consequences. However, in some cases, viral conjunctivitis can take 2 to 3 weeks or more to clear up. A doctor can prescribe antiviral medication to treat more serious forms of conjunctivitis.

Viral Conjunctivitis

• Can occur with symptoms of a cold, flu, or other respiratory infection.
• Usually begins in one eye and may spread to the other eye within days.
• Discharge from the eye is usually watery rather than thick.

Bacterial Conjunctivitis

• More commonly associated with discharge (pus), which can lead to eyelids sticking together.
• Sometimes occurs with an ear infection.

Allergic Conjunctivitis

• Usually occurs in both eyes.
• Can produce intense itching, tearing, and swelling in the eyes.
• May occur with symptoms of allergies, such as an itchy nose, sneezing, a scratchy throat, or asthma.

Conjunctivitis Caused by Irritants

Can produce watery eyes and mucus discharge.
