What is commonly referred to as “red eye disease”?

Conjunctivitis (commonly known as “pink eye”) can occur at any age. After contracting the condition, patients typically experience increased ocular discharge, redness of the eyes, and sometimes itching. Individuals with conjunctivitis should seek prompt treatment and maintain strict hygiene; otherwise, the condition may worsen.

What exactly is “pink eye,” as commonly referred to in everyday language?

“Pink eye” refers to acute catarrhal conjunctivitis—a bacterial infection of the conjunctiva. It usually begins in one eye and spreads to the other within several days. Common causative bacteria include *Streptococcus pneumoniae*, *Staphylococcus aureus*, and *Haemophilus influenzae*. Clinically, it presents with marked conjunctival hyperemia (redness); in severe cases, conjunctival edema may develop, accompanied by increased purulent or mucopurulent discharge. This condition is highly contagious and can easily lead to localized outbreaks.

Conjunctivitis is considered a contact-transmitted infection. Therefore, personal items used by infected individuals—such as towels, washbasins, and toys—must be thoroughly disinfected. If accidental contact with an infected person occurs, immediately wash hands thoroughly with running water, avoid rubbing the eyes with hands, and promptly initiate treatment with topical antibiotic eye drops and/or ointment. Since contact transmission is the primary route of infection, refraining from eye rubbing at all times and practicing frequent handwashing are critically important preventive measures.

Patients are advised to irrigate the conjunctival sac with normal saline to maintain local ocular cleanliness, which facilitates recovery. We hope this information proves helpful.
