Chlamydia in the eye is an infection caused by the bacterium Chlamydia trachomatis, leading to a condition known as inclusion conjunctivitis or chlamydial conjunctivitis. It's important for individuals to recognize how this disease manifests and what potential risks it poses, not only for ocular health but also for overall well-being.


Causes of Chlamydia in the Eye

Chlamydia trachomatis, a type of bacteria, is the main culprit behind eye infections known as inclusion conjunctivitis and trachoma. These conditions can be distressing, causing discomfort and redness in the eyes.

Inclusion conjunctivitis often strikes sexually active young adults through direct exposure to infected genital secretions. This exposure usually happens when hand-to-eye contact occurs after touching genital areas that carry the infective bacteria.

Touching your eyes without washing hands can easily transfer the infection from person to person or even self-inoculate if you're already infected with chlamydial genitourinary disease.

Trachoma, on another hand, is more prevalent in communities with poor sanitation where flies can also transmit the bacterium from one individual's eyes to another's. These modes of transmission highlight why maintaining good personal hygiene is crucial for reducing risk.

Transmission through sexual activity underscores the importance of safe practices and open communication between partners about their health status. Any suspicion or sign of eye infection should prompt individuals to seek medical advice immediately since early detection helps avoid long-term consequences such as vision impairment or blindness associated with these bacterial infections.

Symptoms of Chlamydia in the Eye

Recognizing the symptoms of chlamydia in the eye is crucial for timely treatment and avoiding potential complications. If you notice any of these signs, it's important to consult with a healthcare provider promptly.


  • Red Eye: The affected eye may appear pink or red, signaling inflammation or irritation. This is often one of the first noticeable signs.
  • Eye Discharge: You might see a thick or watery discharge coming from your eye. It can be clear or have a white, yellow, or greenish tint.
  • Eyelid Crusting: After sleeping, you could find your eyelids stuck together due to dried discharge that has accumulated overnight.
  • Itching Sensation: There may be an irritating itch that tempts you to rub your eyes frequently.
  • Swelling: Parts of your eye, particularly the conjunctiva, might become swollen and create a puffy appearance around your eye.
  • Tears and Watering: Your eye might tear up excessively, resulting in constant watering throughout the day.
  • Light Sensitivity: Exposure to light may become uncomfortable or even painful if you have chlamydia in your eye.

Chlamydial Eye Infections in Newborns

Babies born to mothers with untreated chlamydial infections face a significant risk of developing neonatal conjunctivitis. During childbirth, these infants can pick up Chlamydia trachomatis bacteria as they pass through the vaginal canal, which may lead to the infection in their eyes.

Typically, signs of an infection surface within one to two weeks after birth. The newborn's eyelids often become red and swollen, sometimes accompanied by discharge that could be serious if not treated promptly.

Healthcare professionals take this condition seriously because immediate treatment is crucial for preventing long-term eye damage or blindness in affected infants. If a pregnant woman has a known chlamydial infection, doctors will usually treat her prior to delivery to reduce the risk of transmitting the bacteria to the baby.

However, when transmission does occur, antibiotics are available that effectively cure neonatal conjunctivitis caused by Chlamydia trachomatis without causing harm to the infant's delicate system.

Diagnosis of Chlamydia in the Eye

Moving from understanding how chlamydial infections affect newborns, diagnosing chlamydia in the eye for individuals of all ages requires careful examination and testing. Eye doctors often begin with a detailed medical history to determine risk factors and symptoms that suggest an ocular chlamydia infection.

They look for signs like redness, itching, or discharge in one or both eyes.

During a physical exam, they may use special dyes that highlight areas of damage on the surface of the eye caused by inflammation. These dyes can help pinpoint if there's conjunctivitis or trachoma, which are common conditions resulting from Chlamydia trachomatis infection.

The healthcare professional might swab the inside of your eyelids to get a sample. This sample goes through specific tests to detect bacterial DNA or antigens related to Chlamydia.

Laboratory analysis is crucial since many eye infections share similar symptoms but require different treatments. A Polymerase Chain Reaction (PCR) test is often used because it's highly sensitive and can identify even small amounts of bacterial genetic material in the sample taken from your eye.

Sometimes blood tests are also done to check for antibodies against Chlamydia bacteria.

Doctors combine these results with clinical observations to confirm whether you have an ocular chlamydial infection. Detecting this type of infection early helps prevent complications like vision problems before they become more severe.

Treatment Options for Chlamydia in the Eye

Chlamydial eye infections require medical attention to prevent complications. Doctors usually prescribe antibiotics that target the bacteria responsible for the infection.


  • Systemic antibiotics are often recommended to fight ocular chlamydia effectively. This approach treats the whole body and ensures that the infection is eradicated from all affected areas, not just the eyes.
  • Oral azithromycin is a common choice for treatment because it can clear up the infection with a single dose in many cases. Patients appreciate its convenience compared to treatments requiring multiple doses.
  • Doxycycline offers another oral antibiotic option, effective against chlamydial eye infections. It's typically taken over a week or two, depending on the doctor’s recommendation.
  • For those allergic to these medications, erythromycin presents an alternative. It's available as an oral tablet or liquid suspension and helps eradicate bacterial conjunctivitis caused by chlamydia.
  • Treating adult inclusion conjunctivitis involves choosing between several effective antibiotics such as azithromycin or doxycycline, based on individual patient needs and potential allergies.
  • Trachoma, a severe form of ocular chlamydia, was traditionally treated with topical tetracycline ointment; however, oral azithromycin has become more widely adopted for its superior efficacy.
  • To address rectal chlamydia that may accompany ocular infections, studies suggest high cure rates with either doxycycline or azithromycin, demonstrating their versatility in treating different manifestations of the disease.

Prevention of Chlamydia in the Eye

Preventing chlamydia in the eye is crucial for maintaining vision and overall eye health. Effective measures can reduce the risk of infection and the spread of ocular chlamydia. Here's how to safeguard your eyes from this infection:


  • Maintain good hygiene by washing hands thoroughly with soap and water, especially after touching the face or eyes, to prevent the transfer of bacteria.
  • Avoid sharing personal items such as towels, washcloths, and eye makeup that can carry infectious agents from one person to another.
  • Use barrier methods like condoms during sexual activity to reduce the transmission of Chlamydia trachomatis, which can lead to ocular as well as genital infections.
  • Get regular screenings for sexually transmitted infections (STIs), including chlamydia, even if you do not have symptoms; early detection can prevent complications like eye infection.
  • Educate yourself and others about STIs and their potential impact on different parts of the body, including the risk of trachoma prevention related to ocular chlamydia.
  • Access timely ophthalmic antibiotics treatment if you suspect an eye infection or if diagnosed with chlamydia—this will help avoid long-term effects like visual impairment prevention.
