What is a common treatment for bacterial conjunctivitis?

1. Broad-spectrum topical antibiotics

2. Topical antifungal drops

3. Systemic corticosteroids

4. Immediate surgical intervention

The correct answer is: Broad-spectrum topical antibiotics

Broad-spectrum topical antibiotics are commonly used for the treatment of bacterial conjunctivitis because they effectively target a wide range of bacteria that may cause the infection. By using these antibiotics in the form of eye drops or ointments, they can penetrate the conjunctival tissue and help eradicate the offending bacterial pathogens, leading to symptom relief and resolution of the infection. This treatment approach is guided by the understanding that bacterial conjunctivitis typically presents with symptoms such as redness, discharge, and irritation. The choice of broad-spectrum antibiotics is important as it ensures coverage for the most common bacterial causes, including Staphylococcus, Streptococcus, and Haemophilus species. Thus, this treatment strategy effectively addresses the underlying infection, promoting healing and preventing complications. In contrast, the other options do not directly treat bacterial conjunctivitis. Topical antifungal drops are used for fungal infections of the eye, systemic corticosteroids are not first-line treatments for conjunctivitis and can potentially exacerbate infections, and immediate surgical intervention is not indicated for uncomplicated bacterial conjunctivitis.
