Conjunctivitis, commonly known as pink eye, is the inflammation of the conjunctiva, the clear membrane covering the white part of the eye and the inner surface of the eyelids. It causes irritation and discomfort, with symptoms like redness, itching, and discharge. During pregnancy, pink eye can raise concerns about potential risks to both the pregnant individual and the developing fetus.
Understanding Pink Eye’s Nature
Pink eye can stem from various causes, primarily categorized into viral, bacterial, and allergic types. Viral conjunctivitis, the most frequent form, often results from adenoviruses, which are also responsible for the common cold. It typically presents with a watery discharge, redness, and can begin in one eye before spreading to the other, making it highly contagious.
Bacterial conjunctivitis, while less common than viral, is also highly contagious and is caused by bacteria like Staphylococcus aureus or Haemophilus influenza. This type usually leads to a thicker, yellowish or greenish discharge that can cause eyelids to stick together, especially after sleep. Swelling and discomfort are frequently observed, affecting one or both eyes.
Allergic conjunctivitis is an immune response to allergens such as pollen, dust mites, or pet dander. Unlike its infectious counterparts, it is not contagious and typically affects both eyes simultaneously. Its hallmarks include intense itching, redness, and excessive tearing, often accompanied by other allergy symptoms like sneezing or a runny nose.
Impact on Maternal and Fetal Health
For most pregnant individuals, conjunctivitis is a minor ailment that does not pose a significant health risk to either the mother or the fetus. While it primarily causes ocular irritation, specific types can have varying implications.
Viral conjunctivitis, commonly caused by adenoviruses, carries a low risk for both the pregnant individual and the fetus. Though highly contagious and uncomfortable for the mother, it typically resolves on its own without specific antiviral treatment.
Bacterial conjunctivitis from common bacteria is usually localized to the eye and does not typically lead to systemic infection affecting the fetus. However, certain bacterial infections, such as Chlamydia trachomatis or Neisseria gonorrhoeae, can pass to the newborn during vaginal delivery. Untreated chlamydial conjunctivitis in newborns can cause eye infections and pneumonia, while gonococcal conjunctivitis can lead to severe eye infection and potential blindness.
Allergic conjunctivitis does not pose any direct risk to the developing fetus, as it is an immune reaction to an allergen, not an infection. Symptoms are confined to the eyes, with no infectious agent to transmit. Ocular complications for the mother are generally mild and resolve with appropriate management.
Safe Management During Pregnancy
Managing pink eye during pregnancy prioritizes the safety of both the pregnant individual and the developing baby. Non-pharmacological methods often alleviate symptoms. Applying cool or warm compresses to the affected eye can reduce discomfort and inflammation. Gently cleaning eyelids with a clean, wet cloth can remove crusty discharge.
Over-the-counter artificial tears are generally safe during pregnancy, as they moisturize eyes without medication. For bacterial conjunctivitis, a healthcare provider may prescribe antibiotic eye drops. Erythromycin and polymyxin B eye drops are often safe for use in pregnancy, and chloramphenicol eye drops are also safe if not used around delivery.
For allergic conjunctivitis, avoiding the allergen is the primary recommendation. If relief is needed, certain antihistamine eye drops, such as those containing sodium cromoglicate, are safe because very little medication is absorbed systemically. Oral antihistamines like cetirizine or loratadine are also often safe options.
It is important to seek medical attention if symptoms worsen, if there is severe pain, changes in vision, or if symptoms persist despite home care. Pregnant individuals should always inform their healthcare provider about their pregnancy status when discussing treatment options for pink eye.
Preventive Measures
Preventing pink eye involves practicing good hygiene. Frequent and thorough hand washing with soap and water for at least 20 seconds is effective. Avoiding touching or rubbing eyes, especially with unwashed hands, can prevent the transfer of infectious agents.
Not sharing personal items like towels, washcloths, pillowcases, or eye makeup is important to prevent transmission. These items can harbor viruses or bacteria that cause pink eye. Regularly washing bedding and towels in hot water and detergent can further reduce the risk of spread within a household.
Avoiding close contact with individuals who have pink eye can minimize exposure to contagious forms. If someone in the household has pink eye, maintain separate personal items and adhere strictly to hand hygiene practices.
