Chlamydial Conjunctivitis
Understanding chlamydial conjunctivitis is crucial for proper diagnosis and treatment. This eye infection, caused by the bacterium Chlamydia trachomatis, can often be confused with other forms of conjunctivitis, such as viral or bacterial conjunctivitis. However, accurate diagnosis and timely treatment can prevent complications and promote rapid recovery.
What is Chlamydial Conjunctivitis?
Chlamydial conjunctivitis is an eye infection resulting from the bacterium Chlamydia trachomatis. This bacterium is primarily known for causing sexually transmitted infections, but it can also infect the eyes, leading to conjunctivitis. It can be contracted through direct or indirect contact with infected genital secretions or through autoinoculation, where the infection spreads from the genital area to the eyes.
Causes of Chlamydial Conjunctivitis
The primary cause of chlamydial conjunctivitis is the bacterium Chlamydia trachomatis. There are several ways through which this bacterium can infect the eye:
- Sexual Contact: Direct contact with infected genital secretions can lead to ocular infection.
- Autoinoculation: Transferring the bacteria from the genital area to the eyes through hands or contaminated objects.
- Neonatal Transmission: Infants can acquire the infection during birth from an infected mother.
Understanding the pathways of infection is essential for prevention and control of the disease.

Initial Symptoms
Chlamydial conjunctivitis often presents with symptoms that can be mistaken for other types of conjunctivitis. Common initial symptoms include:
- Redness: The eye may appear red and inflamed.
- Discharge: There is often a mucopurulent discharge, which can be sticky and yellowish.
- Irritation: Patients may experience itching or a gritty sensation in the eye.
- Tearing: Excessive tearing or watering of the eyes is common.
Advanced Symptoms
If left untreated, the infection can progress, leading to more severe symptoms:
- Swelling: The eyelids may become swollen and puffy.
- Photophobia: Sensitivity to light can develop, causing discomfort in bright environments.
- Blurred Vision: Vision may become blurry due to the discharge and inflammation.

Chlamydial Conjunctivitis vs. Viral Conjunctivitis
Differentiating chlamydial conjunctivitis from viral conjunctivitis is critical for proper treatment. While they share some common symptoms, certain distinguishing features can help in diagnosis.
Chlamydial Conjunctivitis
- Discharge: Mucopurulent and sticky.
- Onset: Gradual, often associated with genital infection.
- Duration: Can persist for weeks if untreated.
- Swelling: Significant eyelid swelling and photophobia.
Viral Conjunctivitis
- Discharge: Watery and less sticky.
- Onset: Sudden, often following an upper respiratory tract infection.
- Duration: Typically resolves within 1-2 weeks.
- Swelling: Mild eyelid swelling, less severe photophobia.
Diagnosis of Chlamydial Conjunctivitis
Accurate diagnosis is essential for effective treatment. Several diagnostic methods can be employed:
Clinical Examination
A thorough clinical examination by an ophthalmologist can reveal characteristic signs of chlamydial conjunctivitis, such as follicular conjunctivitis and preauricular lymphadenopathy.
Laboratory Tests
- Polymerase Chain Reaction (PCR): A highly sensitive test that can detect Chlamydia trachomatis DNA in conjunctival swabs.
- Direct Fluorescent Antibody (DFA) Test: Detects chlamydial antigens in conjunctival cells.
- Culture: Chlamydia trachomatis is growing in cell culture from conjunctival swabs.

Antibiotic Therapy
The cornerstone of treatment for chlamydial conjunctivitis is antibiotic therapy. Oral antibiotics are preferred due to the systemic nature of the infection:
- Azithromycin: A single-dose therapy that is highly effective.
- Doxycycline: An alternative, typically taken for 7-14 days.
Topical Antibiotics
In addition to oral antibiotics, topical antibiotics may be prescribed to alleviate local symptoms:
- Erythromycin ointment: Applied to the affected eye several times a day.
Follow-Up and Prevention
Follow-up is crucial to ensure the infection has been eradicated. Patients should be advised to:
- Complete the Full Course of Antibiotics: Even if symptoms improve.
- Avoid Sharing Personal Items: Towels, makeup, and other personal items should not be shared.
- Practice Good Hygiene: Regular handwashing and avoiding touching the eyes can prevent autoinoculation.
Complications of Untreated Chlamydial Conjunctivitis
If left untreated, chlamydial conjunctivitis can lead to serious complications:
Corneal Involvement
Chronic infection can lead to corneal ulcers, scarring, and even vision loss.
Chronic Conjunctivitis
Persistent inflammation can result in chronic conjunctivitis, which is more difficult to treat.
