Bacterial conjunctivitis

Bacterial Conjunctivitis is an infection of the eye's conjunctiva typically caused by bacteria. It is one of the most common types of conjunctivitis, alongside viral and allergic conjunctivitis.

Causes

Bacterial conjunctivitis is usually caused by Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, or, less commonly, Chlamydia trachomatis. The bacteria can be spread through direct contact with an infected individual or by touching objects that have been contaminated by the bacteria.

Symptoms

The primary symptoms of bacterial conjunctivitis include redness in the white of the eye or inner eyelid, increased amount of tears, thick yellow discharge that crusts over the eyelashes, especially after sleep, green or white discharge from the eye, itchy eyes, burning eyes, blurred vision, increased sensitivity to light.

Diagnosis

Diagnosis of bacterial conjunctivitis is typically based on symptoms and physical examination of the eye. In some cases, a sample of the discharge from the eye may be taken to determine the type of bacteria causing the infection.

Treatment

Treatment for bacterial conjunctivitis usually involves the use of antibiotic eye drops or ointments. In severe cases, oral antibiotics may be prescribed. It is important to complete the full course of antibiotics to prevent recurrence of the infection.

Prevention

Prevention strategies for bacterial conjunctivitis include regular hand washing, avoiding touching the eyes with unwashed hands, and not sharing personal items like towels or makeup.
