What Are The Different Types Of Conjunctivitis

Conjunctivitis is usually divided into at least two categoriesnewborn conjunctivitis and childhood conjunctivitiswith different causes and treatments for each.

  • Childhood conjunctivitis. Childhood conjunctivitis is a swelling of the conjunctiva and may also include an infection. It is a very common problem in children. Also, large outbreaks of conjunctivitis are often seen in daycare settings or schools. The following are the most common causes of childhood conjunctivitis:

    • Pink or red discoloration of the whites of one or both eyes

    • Discomfort when the child looks at a light

    • Burning in the eyes

    The symptoms of conjunctivitis may resemble other medical conditions or problems. Always consult your childs doctor for a diagnosis.

    What Is The Best Pink Eye Medication

    There are several treatments for conjunctivitis, but there is no “best” medication. What works for one person might not work for another. Everyone reacts differently to medicines. Your doctor will take your medical condition, medical history, and other medication you are taking into consideration when suggesting a treatment for you. When looking at standard dosing, it is important to keep in mind that interval frequency and duration of treatment may vary based on the severity of each patients case.

    Can Pink Eye Come Back

    Pink eye can come back, especially if you have allergy-related pink eye. Every time youre in contact with the allergen , your eyes may react.

    If you have bacterial or viral pink eye, you can also accidentally reinfect yourself. To avoid coming down with another case of contagious pink eye:

    • Wash your bed linens, pillowcases, towels and washcloths in hot water and detergent. Change them frequently.
    • Avoid wearing eye makeup until the infection goes away. Throw out old eye makeup and any makeup used just before the start of the infection.
    • Wear glasses instead of contact lenses. Clean your glasses often.
    • Throw away disposable contact lenses. Thoroughly clean extended wear lenses and all eyewear cases. Use only sterile contact solution. Wash your hands before inserting or removing lenses.
    • If youve used eye drops for an infected eye, dont use the same eye drops in a non-infected eye.

    Whats The Treatment For Pinkeye

    The treatment depends on the cause.

    Viruses. This type of pinkeye often results from the viruses that cause a common cold. Just as a cold must run its course, the same is true for this form of pinkeye, which usually lasts from 4 to 7 days. Remember, it can be very contagious, so do everything you can to prevent its spread. Antibiotics will not help anything caused by a virus. Pinkeye caused by the herpes virus can be very serious and may need prescription antiviral eye drops, ointment, or pills.

    Bacteria. If bacteria, including those related to STDs, caused your pinkeye, youâll take antibiotics. You may need to apply eye drops or ointments to the inside of your eyelid three to four times a day for 5 to 7 days. For more stubborn infections or for rare cases of pinkeye caused by gonorrhea or chlamydia, you might get an oral antibiotic. You would take pills for several days. The infection should improve within a week. Take or use the medicines as instructed by your doctor, even after the symptoms go away.

    Irritants. For pinkeye caused by an irritating substance, use water to wash the substance from the eye for 5 minutes. Your eyes should begin to improve within 4 hours. If your conjunctivitis was caused by acid or alkaline material such as bleach, immediately rinse the eyes with lots of water and call your doctor right away.

    Your eye doctor may have you return in several days to make sure your pinkeye is improving with the medication prescribed.

    If you cant get an in-person visit, you might be able to do a video visit instead. Telehealth when patients and health care providers use technology for the remote diagnosis and treatment of some health conditions is becoming more and more popular. Ask your health care provider if his or her practice participates in telemedicine, and check with your insurance provider to see if this option is covered.

    Your doctor may prescribe you antibiotic eye drops if you have:

    Bacterial Conjunctivitis

    Its also important to kill bacteria causing a contact-lens infection. Sleeping in contact lenses is one of the most common causes of bacterial eye infections.


    Styes cause inflammation at the edge of the eyelid. They are red and painful. Staphylococcus bacteria cause styes, which occur when bacteria build up in an oil gland near the base of an eyelash.


    Chalazion, which are similar to styes, are cysts deep in the eyelid. Inflammation from blocked meibomian glands causes chalazion. This blockage can lead to staphylococcus bacteria entering the gland opening.

    Antibiotic treatments only treat bacterial eye infections. They wont help with viral infections or fungal infections or if you have an allergic reaction. For eye problems in these categories, youll need antihistamines or antiviral medications.


    Antibacterial eye drops treat eye infections such as bacterial conjunctivitis, contact lens infections, styes, and chalazion. They do not work against viruses, fungi, or allergic reactions.

    How Long Does Pink Eye Last

    While the good news is that in most cases pink eye resolves on its own, you’re likely wondering how long this may take. If you have mild bacterial conjunctivitis, this will likely start to clear up without treatment within about two to five days. Still, it may take as long as two weeks for this to completely dissipate.

    Meanwhile, if you have a mild case of viral conjunctivitis, this will take a week or two to go away in most cases. But for some this may take as much as two or even three weeks to resolve.

    Antibiotics won’t do anything to help with viral conjunctivitis. But if you have a more serious virus such as herpes simplex virus or varicella-zoster virus causing the virus, your healthcare provider can prescribe antiviral medication to help combat these.
