Should conjunctivitis (“pink eye”) be treated with antibiotics?

　　Conjunctivitis—commonly known as “pink eye”—is a prevalent ocular infectious disease, yet it is not inherently dangerous. Practicing good eye hygiene in daily life—such as avoiding sharing handkerchiefs or towels and refraining from touching the face or eyes with contaminated cloths—can significantly reduce the risk of infection. Patients diagnosed with conjunctivitis should not panic; instead, they should maintain ocular cleanliness and adhere strictly to prescribed medication regimens. But does conjunctivitis require antibiotic treatment?

　　Is Antibiotic Treatment Necessary for Conjunctivitis?

　　Yes, antibiotic treatment is often required for conjunctivitis. Medically, this condition is typically termed acute infectious conjunctivitis—an acute inflammatory response triggered by bacterial, viral, or other infectious agents. Its incubation period usually lasts one to two weeks. Affected individuals commonly experience severe ocular symptoms that progress rapidly and exhibit high transmissibility. Clinical manifestations include photophobia, excessive tearing, decreased visual acuity, copious ocular discharge, conjunctival hyperemia (redness), and ocular pain. Upon diagnosis, patients should be isolated, avoid contact with others’ ocular secretions, and promptly receive anti-inflammatory therapy.

　　The typical disease course lasts approximately three to four weeks. Key features include marked conjunctival hyperemia accompanied by purulent or mucopurulent discharge. Conjunctivitis spreads primarily through direct contact with infected individuals or via shared personal items (e.g., towels, pillowcases). In some cases, corneal involvement or infection may occur; if corneal lesions develop, visual acuity may decline.

　　In daily life, patients should maintain a positive mindset, actively cooperate with their physicians’ treatment plans, take medications on time and in the correct dosage, and pay close attention to routine ocular care—thereby facilitating prompt clinical improvement.
