Pink eye, or conjunctivitis, is generally classified into three main types: viral, bacterial, and allergic




Bacterial Conjunctivitis: Causes, Symptoms, and Treatment
What is Bacterial Conjunctivitis? Bacterial conjunctivitis, commonly known as “pink eye,” is an infection of the conjunctiva, the thin, transparent membrane covering the white part of the eye and inner eyelid. It is caused by bacteria and leads to redness, irritation, and discharge from the eyes. The condition is highly contagious and can spread through direct or indirect contact with an infected person.


Causes of Bacterial Conjunctivitis
Bacterial Conjunctivitis is primarily caused by bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.
These bacteria can be transmitted through:
- Touching the eyes with unwashed hands
- Sharing personal items like towels, makeup, or contact lenses
- Exposure to contaminated surfaces
- Respiratory droplets from coughing or sneezing
Symptoms of Bacterial Conjunctivitis
- Redness in the white part of the eye
- Thick yellow, green, or white discharge, especially after sleep
- Swollen eyelids
- Gritty or burning sensation in the eyes
- Excessive tearing
- Sensitivity to light (photophobia)
- Crusting around the eyelids


Diagnosis
A healthcare professional can diagnose bacterial conjunctivitis through a physical examination of the eye. In severe or recurrent cases, a sample of the eye discharge may be tested to identify the specific bacteria responsible for the infection.
Treatment Options
Most cases of bacterial conjunctivitis resolve within a few days to two weeks with proper treatment. Common treatments include:
- Antibiotic Eye Drops : Soothe® Antibiotic Drops eliminates the bacteria causing the infection.
- Proper Hygiene: Frequent handwashing, avoiding touching the eyes, and not sharing personal items can prevent the spread of infection
- Warm Compresses: Applying a clean, warm washcloth to the eyes can help soothe irritation and remove crusting


Prevention Tips
- Wash hands frequently and thoroughly
- Avoid rubbing or touching the eyes
- Disinfect frequently-touched surfaces
- Replace eye makeup regularly and avoid sharing cosmetics
- Follow proper contact lens hygiene
When to Seek Medical Attention Seek medical care if:
- Symptoms worsen or do not improve within a few days
- There is severe eye pain, vision changes, or sensitivity to light
- The infection spreads to both eyes
Bacterial conjunctivitis is a common and treatable condition. By following proper hygiene and seeking timely treatment, symptoms can be managed effectively, and the spread of infection can be minimized.
