About Gonococcal Conjunctivitis (Pink Eye)

Overview

Gonococcal conjunctivitis is a form of pink eye that occurs due to an infection with the bacteria Neisseria gonorrhoeae, which is the same bacteria that causes gonorrhea. It can affect both newborns and adults. In newborns, the infection is usually passed during delivery from a parent with gonorrhea. The bacteria can spread to the baby's eyes during birth, even in cases of cesarean delivery (C-section). Prompt treatment is important to prevent complications such as corneal perforation, scarring, and blindness. In adults, gonococcal conjunctivitis typically occurs when infected genital fluids, such as semen, come into contact with someone's eyes. Symptoms may include red eyes, thick pus in the eyes, and swelling of the eyelids and conjunctiva (the clear layer covering the white part of the eye). Treatment should be guided by an infectious disease specialist due to limited information on treatment options for adults with this condition.

Causes and Risk Factors

The root causes of gonococcal conjunctivitis (GC) are as follows:

• GC is caused by the bacteria Neisseria gonorrhea, which is the cause of sexually transmitted gonorrhea infections.
• It can be spread through direct contact with infected fluids in the vagina or semen that make contact with someone's eyes.
• In newborns, GC can occur when a baby passes through the birth canal and is exposed to the mucus-filled linings of the cervix and urethra, which can carry high concentrations of gonorrhea bacteria during an active infection.
• In adults, GC most commonly occurs when bodily fluids from someone with gonorrhea make contact with someone else's eyes.

The non-modifiable risk factors for GC cannot be changed or controlled. These include:

• Being born to a mother with gonorrhea.
• Age: GC is more common in younger adults.
• Being immunocompromised (having a weakened immune system).

The modifiable risk factors for GC can be influenced or changed. These include:

• Sexual activity: Engaging in unprotected sexual intercourse, especially with multiple partners, increases the risk of contracting GC.
• Poor hygiene: Not practicing good hygiene, such as not washing hands regularly or touching the eyes after touching infected fluids or objects, can increase the risk.

It's important to note that these risk factors can vary depending on individual circumstances. It is always recommended to consult with a healthcare professional for personalized advice and guidance.

Symptoms

The most common early symptoms of gonococcal conjunctivitis (GC) include:

• Redness
• Itching
• Feeling like there’s something in the eye
• Watery eyes
• Thick discharge

As GC progresses or becomes more severe, other symptoms may occur. These can include:

• Swollen eyelids
• Fluid-filled blister-like growths on the eye surface (chemosis)
• Bleeding from blood vessels below the eye surface (subconjunctival hemorrhage)
• Blurred vision
• Sensitivity to light (photophobia)
• Fever

It's important to consult a doctor if you suspect you have GC or experience any of these symptoms. They can provide a proper diagnosis and recommend appropriate treatment options.

Diagnosis

To diagnose gonococcal conjunctivitis, the following examinations, tests, and procedures are commonly performed:

• Physical exam: The healthcare provider will look for physical signs of the infection, such as pain, swelling, or discharge from the eyes.
• Medical history: Your healthcare provider will gather information about your medical history and any previous diagnoses.
• Smear examination: In newborns, a smear of eye discharge is examined under a microscope to confirm the presence of the infection.
• Gram stain: In adults, a sample of eye discharge is smeared onto a glass slide and sent to a lab for a special stain to highlight the gonorrhea bacteria.
• Polymerase chain teaction (PCR) test: A swab of eye discharge or tissue is taken to test for the presence of DNA associated with gonorrhea.

Remember that specific examinations, tests, and procedures may vary depending on individual circumstances. It's important to consult with your healthcare provider for personalized recommendations.

Treatment Options

The main goal is to eliminate the Neisseria gonorrhoeae bacteria causing the conjunctivitis.

The recommended treatment options include:

• Medications:
  • Antibiotics such as ceftriaxone and azithromycin are commonly prescribed to treat gonococcal conjunctivitis. These medications work by targeting and killing the bacteria responsible for the infection.
  • Antibiotic eye ointments, such as erythromycin and tetracycline, are often used in newborns to treat the infection.
• Therapeutic procedures: A single lavage (rinse) of the infected eye with saline solution may be considered as part of the treatment plan.
• Self-care and health behavior changes: Patients should be advised to have their sexual partners evaluated and treated to prevent reinfection and stop the spread of the infection.

It is important to note that consultation with an infectious disease specialist should be considered due to limited information on treatment for gonococcal conjunctivitis in adults.

Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
