Pink Eye - Causes, Treatments and Contagion

Pink Eye is a common eye condition that causes inflammation and redness in the conjunctiva, the thin membrane that covers the white part of the eye. It can be caused by several factors, including viruses, bacteria, allergies, and irritating substances. In this article, we will briefly explain the different treatments available to treat the pink eye, how long it can live on surfaces, what common conditions are incorrectly diagnosed as conjunctivitis, and other topics associated with this disease.

Types and Treatments of conjunctivitis

Treatment for conjunctivitis depends on its cause. Bacterial conjunctivitis is usually treated with eye drops such as moxifloxacin or antibiotic ointments. Viral conjunctivitis, on the other hand, does not respond to antibiotics and typically resolves on its own within one to two weeks. Allergic conjunctivitis can be controlled, among others, with vasoconstrictor drugs, antihistamines or corticosteroids. Allergic conjunctivitis is very contagious and can spread quickly in settings such as schools or daycares. Adenoviral conjunctivitis usually resolves on its own within one to two weeks, but it is important to seek medical advice for proper treatment to prevent the spread of the virus.

Contagion and surfaces

Pink eye can be very contagious, especially in its early stages. It can be transmitted through direct contact with infected people or by touching contaminated surfaces. The duration that conjunctivitis can live on surfaces varies depending on the cause. Bacterial and viral conjunctivitis can survive on surfaces for several hours to a few days. To prevent the spread of conjunctivitis, it is essential to practice good hygiene, such as washing your hands frequently and avoiding touching your eyes.

Common misdiagnoses

The symptoms of conjunctivitis can sometimes be like other eye conditions, leading to misdiagnosis. Conditions that are confused with conjunctivitis include dry eye syndrome, blepharitis (inflammation of the eyelids), and allergic reactions. If you experience persistent or worsening symptoms, it is essential to seek medical advice for an accurate diagnosis and appropriate treatment.

Duration of recovery with medication

How long conjunctivitis disappears with medication depends on the cause and the individual's response to treatment. Bacterial conjunctivitis usually improves within a few days of starting antibiotic treatment. However, viral conjunctivitis may take longer to resolve and usually lasts one to two weeks. It is important to complete the full course of prescribed medication, even if symptoms improve, to prevent recurrences or complications.

Infection after using eye drops

Pink eye can remain contagious even after starting eye drop treatment. Bacterial conjunctivitis becomes less contagious within 24 to 48 hours after starting antibiotics, but it is still advisable to avoid close contact with other people until symptoms have completely disappeared. Unfortunately, viral conjunctivitis remains contagious as long as symptoms persist.

Sinus infections and conjunctivitis

While sinus infections and conjunctivitis are separate conditions, they can sometimes occur together. Sinus infections can cause eye symptoms, such as redness and irritation, due to the proximity of the sinuses to the eyes. If you suspect that a sinus infection may be contributing to your pink eye symptoms, it is advisable to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.

Conclusion

Conjunctivitis is a common eye condition that can be caused by several factors. It is important to reiterate that the correct and responsible thing to do for anyone who presents any of the symptoms mentioned above is to go to a doctor to obtain appropriate professional care in the diagnosis and treatment of this disease. Also practice good hygiene and take necessary precautions to help prevent the spread of conjunctivitis.
