How to treat Conjunctivitis Symptoms – Types of Conjunctivitis

Irritant Conjunctivitis Causes and Conjunctivitis Symptoms

To treat allergic conjunctivitis (pink eye) and conjunctivitis symptoms. Conjunctivitis or pink eye is caused by a variety of factors or types of Conjunctivitis

Types of Conjunctivitis:

  • viruses or Viral conjunctivitis
  • bacteria or bacterial conjunctivitis
  • allergens or allergic conjunctivitis

There are many other reasons.

It’s tough to pinpoint the specific cause of conjunctivitis because conjunctivitis symptoms are similar regardless of the reason.

1. Viral Conjunctivitis caused by a virus

A virus causes an infection of the eye that is known as viral conjunctivitis Adenoviruses, for example, are one type of virus that can cause this. It’s really infectious. Depending on the virus, this can sometimes result in huge epidemics.

Viral conjunctivitis treatment is explained at the end of this blog.

2. Bacterial Conjunctivitis is caused by bacteria

Bacterial Conjunctivitis is an infection of the conjunctiva caused by bacteria.

Staphylococcus aureus, Streptococcus pneumonia, Hemophilic influenza, Moraxella catarrhalis, and, less often, Chlamydia trachomatis and Neisseria gonorrhea are among the bacteria that can cause it.

It’s easy to spread, especially with specific germs and in certain environments.

Children with conjunctivitis who do not have a fever or exhibit any behavioral abnormalities can typically return to school.

It is more prevalent in children than in adults.

More commonly observed from December until April

It is not infectious.

It’s more common in those who have other allergy diseases like hay fever, asthma, or eczema.

Seasonally, when allergens such as pollen levels are high, this might happen.

Indoor allergens, such as dust mites and animal dander, can cause allergic Conjunctivitis symptoms all year.

Irritant Conjunctivitis Causes:

Irritation from a foreign body in the eye or contact with smoke, dust, fumes, or chemicals causes this condition.

It is not infectious.

When contact lenses are used for longer than advised or are not properly cleaned, this might happen.

Conjunctivitis symptoms

Conjunctivitis (pink eye) can cause a variety of symptoms.

The white of the eye can be pink or red (s)

Swelling of the conjunctiva and/or eyelids (the thin layer that borders the white area of the eye and the inside of the eyelid)

Tear production has increased.

Feeling as though something alien is in your eye(s) or the want to wipe your eyes,

Itching, discomfort, and/or burning are all possible conjunctivitis symptoms.

Releasing (pus or mucus)

Crusting of the eyelids or lashes, particularly first thing in the morning

Contact lenses that are unpleasant to use and/or do not remain on the eye

Other symptoms may appear depending on the reason.

Conjunctivitis caused by a virus might appear with symptoms of a cold, flu, or other respiratory infection.

It usually starts in one eye and spreads to the other within a few days.

Eye discharge is generally liquid rather than thick.

Bacterial Conjunctivitis is caused by bacteria

Eyelids that cling together are more often connected with discharge (pus).

This might happen when you have an ear infection.

Allergic Conjunctivitis

It usually affects both eyes.

Itching, weeping, and swelling of the eyes are possible side effects.

Allergy symptoms, such as a runny nose, sneezing, a scratchy throat, or asthma, may develop.

Irritants Cause Conjunctivitis

Watery eyes and mucous discharge are possible side effects.

How does it spread?

Conjunctivitis (pink eye) is caused by a variety of viruses and bacteria, some of which are very infectious. Each of these viruses can spread in different ways from person to person. They are generally transferred from one sick individual to another through sexual contact.

Touching or shaking hands in close proximity is one example of close personal contact.

Coughing and sneezing pollute the air

Before washing your hands, contact an object or surface that has germs on it, then touch your eyes.

When should I return to work or school?

With your doctor’s permission, you may be able to stay at work or school if you have conjunctivitis but no fever or other symptoms.

If you still have symptoms and your work or school activities need close contact with others, you should not go.


Based on the patient’s history, symptoms, and an examination of the eye. A doctor can usually identify whether conjunctivitis (pink eye) is caused by a virus, bacteria, or allergy. Conjunctivitis is characterized by redness or swelling of the eyes, but it can also present with additional symptoms that vary depending on the etiology. These signs and symptoms might help a doctor figure out what’s causing your conjunctivitis. However, it can be difficult to obtain a definitive diagnosis because certain symptoms are similar regardless of the reason.

It’s also often tough to figure out what’s causing the problem without doing laboratory tests. Your healthcare practitioner may take a sample of your eye disc, however it is not frequently done.

Allergic Conjunctivitis

If conjunctivitis occurs seasonally when pollen counts are high, the patient’s eyes itch badly, and the patient has other indications of allergic illness, such as hay fever, asthma, or eczema, the reason is most likely allergic.


Keeping Conjunctivitis from Spreading

Hand washing

Conjunctivitis (pink eye) is highly infectious, both viral and bacterial. They can readily transmit from one person to another. By following a few easy hygiene procedures, you may substantially minimize your chances of developing conjunctivitis or transmitting it to others.

Conjunctivitis is a kind of conjunctivitis that affects the eyes

If you have conjunctivitis, you may help prevent it from spreading to others by doing the following steps:

Hands should be washed regularly with soap and warm water for at least 20 seconds. Before and after cleaning, or administering eye drops or ointment to, your infected eye, wash them thoroughly. If soap and water aren’t accessible, clean your hands using an alcohol-based hand sanitizer that contains at least 60% alcohol. (For more information on appropriate hand washing, see the CDC’s Clean Hands Save Lives! page.)

Touching or rubbing your eyes is not a good idea. This might aggravate the problem or transmit it to your other eye.

Using a clean, damp washcloth or fresh cotton ball, cleanse any discharge from around your eye(s) multiple times a day using clean hands. Cotton balls should be discarded after each usage, and soiled washcloths should be washed in hot water with detergent.

Use a different eye drop dispenser/bottle for infected and non-infected eyes.

Pillowcases, sheets, washcloths, and towels should be washed often in hot water with detergent, and your hands should be washed after handling such items.

Wearing contact lenses is not recommended unless your eye doctor advises it is safe to do so.

Clean your spectacles, being cautious not to contaminate objects that may be shared by others (such as hand towels).

Your eye doctor will tell you how to clean, store, and change your contact lenses.

Pillows, washcloths, towels, eye drops, eye or face cosmetics, makeup brushes, contact lenses, contact lens storage cases, or eyeglasses should not be shared.

Swimming pools should not be used.

If You’re in the Company of Someone with Conjunctivitis

If you’re near someone who has conjunctivitis, take these precautions to avoid becoming infected:

Hands should be washed regularly with soap and warm water for at least 20 seconds. If soap and warm water aren’t available, clean your hands using an alcohol-based hand sanitizer that contains at least 60% alcohol. (For more information on appropriate hand washing, see the CDC’s Clean Hands Save Lives! page.)

Wash your hands after coming into touch with an infected person or the objects he or she uses, such as administering eye drops or ointment to an infected person’s eye(s) or putting their bed linens in the washer.

Touching your eyes with unclean hands is not a good idea.

Do not share pillows, washcloths, towels, eye drops, eye or face cosmetics, makeup brushes, contact lenses, contact lens storage cases, or eyeglasses that have been used by an infected individual.

Avoid Getting Sick Once More

Furthermore, if you have conjunctivitis, you may take precautions to avoid re-infection once the illness has cleared up:

Tips for using contact lenses

Any eye or face makeup, as well as any makeup brushes that you used while sick, should be thrown away and replaced.

Discard any disposable contact lenses or cases you may have worn while your eyes were infected.

Contact lens solutions that you used when your eyes were sick should be thrown away.

As instructed, clean extended-wear lenses.

Clean your eyeglasses and cases from when you were infected.

Vaccines can help avoid some conjunctivitis-related illnesses.

There is no conjunctivitis vaccination that protects against all forms of conjunctivitis. There are, however, vaccinations available to protect against several viral and bacterial infections linked to conjunctivitis:

  • Rubella
  • Measles
  • Chickenpox
  • Shingles
  • Pneumococcal

Type b Hemophilic influenza (Hib)

If a subsequent viral or bacterial infection develops, conjunctivitis induced by allergies or irritants is infectious.

for clinicians

Viruses, bacteria, allergies, contact lens usage, chemicals, fungus, and certain illnesses are all potential causes of conjunctivitis.

Except when viral or bacterial conjunctivitis is accompanied by systemic symptoms of illness, schools should allow affected children to continue in school until any necessary therapy has been administered. Infected kids should not attend school if their conduct makes it impossible for them to avoid close contact with other students.

Conjunctivitis caused by a virus

Viral conjunctivitis can be caused by a variety of viruses, with adenoviruses being one of the most common:


Rubella virus Rubella virus (measles)

Herpesviruses, such as the Herpes simplex virus (HSV) and the Varicella-zoster virus (VZV), which cause chickenpox and shingles,

Picornaviruses, such as coxsackievirus A24 and enterovirus 70, cause infectious mononucleosis (mono) Epstein-Barr virus, which also causes infectious mononucleosis (mono) (which has caused outbreaks in other countries).

Conjunctivitis caused by a virus is extremely infectious. Most viruses that because conjunctivitis transmits by hand-to-eye contact with infectious virus-infected hands or objects. Hands can get contaminated after coming into touch with infected tears, eye fluid, faces, or respiratory secretions. Large respiratory tract droplets might potentially transmit viral conjunctivitis. Infected persons should be advised on how to prevent transmission, such as washing hands often, using separate towels, and avoiding close contact with others during the period of it.

Some individuals may experience additional symptoms or problems, depending on the etiology of viral conjunctivitis:

  • Whether it’s a common cold, the flu, or another respiratory illness,
  • Herpetic keratoconjunctivitis — a form of conjunctivitis caused by the herpes simplex virus and characterized by blister-like skin lesions; it can affect only one eye.
  • Rubella and rubella (measles) – these viral rash diseases can cause conjunctivitis, which is generally accompanied by a rash, fever, and cough.


When it comes to conjunctivitis, it’s sometimes necessary to seek medical help (pink eye). This isn’t always required, though. Cold compresses and artificial tears, which may be purchased over the counter without a prescription, can help reduce some of the irritation and dryness produced by conjunctivitis. You should also refrain from wearing contact lenses until your eye doctor advises it’s safe to do so. If you didn’t need to see a doctor, don’t put your contacts in until you’re no longer experiencing pink eye or conjunctivitis symptoms.

When Should You Seek Medical Help?

If you have conjunctivitis and any of the following symptoms, you should consult a doctor:

When the discharge is wiped from the eye, it causes discomfort, sensitivity to light, or impaired vision that may not improve (s)

a weakened immune system, such as from HIV infection, cancer treatment, or other medical conditions or treatments, symptoms that get worse or don’t improve, such as pink eye thought to be caused by bacteria that doesn’t improve after 24 hours of antibiotic use a weakened immune system, such as from HIV infection, cancer treatment, or other medical conditions or treatments

Conjunctivitis symptoms in newborns should be examined by a doctor straight away.

Conjunctivitis caused by a virus

The majority of viral conjunctivitis cases are minor. Without treatment, the infection generally clears itself in 7 to 14 days with no long-term effects. Viral conjunctivitis, on the other hand, might take up to 3 weeks to clear up in certain situations.

Antiviral medicine might be prescribed by a doctor to treat more serious cases of conjunctivitis. Conjunctivitis caused by the herpes simplex virus or the varicella-zoster virus, for example. Antibiotics are ineffective against viruses; therefore, they won’t help in viral conjunctivitis.

Bacterial conjunctivitis

Mild bacterial conjunctivitis may clear up without the need for antibiotics and without creating problems. It usually improves in 2 to 5 days without therapy, although it might take up to 2 weeks to entirely disappear.

For bacterial conjunctivitis, your doctor may prescribe an antibiotic, which is generally administered topically as eye drops or ointment. Antibiotics may aid in shortening the duration of an illness, reducing consequences, and preventing the transmission of infection to others. In the following situations, antibiotics may be required:

When conjunctivitis occurs in persons who have a weakened immune system, there is a discharge (pus).

When a certain bacterium is suspected,

Consult your physician.

Conjunctivitis Allergic

When an allergen (such as pollen or animal dander) causes conjunctivitis, the condition generally improves if the allergen is removed from the person’s surroundings. Allergy medicines and specific eye drops (topical antihistamines and vasoconstrictors), including certain prescription eye drops, can help with allergic conjunctivitis relief. In certain situations, your doctor may prescribe a medication cocktail to alleviate symptoms. If you have caused by an allergy, your doctor can assist.

Phlyctenular keratoconjuctivitis

Phlyctenular keratoconjunctivitis is an eye condition in which the cornea (the transparent layer in front of the iris and pupil) and conjunctiva (the membrane that lines the eyelids and covers the white of the eye) respond to bacteria with an immune response.

On the eye, little yellow-gray raised lumps appear.

Eye redness, impaired vision, sensitivity to strong light, a sense of a foreign object trapped in the eye, and occasionally visible flakes of dead skin at the margins of the eyelids are all common symptoms.

The look of the eye helps doctors diagnose phlyctenular keratoconjunctivitis.

Eye drops or eyelid washes are used to treat the condition.

An In-Depth Examination of the Eye

It is not an infection that causes phlyctenular keratoconjunctivitis. It’s an immunological response to germs found on or around the eyes. Staphylococci, TB, and Chlamydia are some of the microorganisms that cause this disease. This is a more frequent condition among youngsters.


Phlyctenules are little yellow-gray raised bumps that develop at the limbus (the point where the conjunctiva meets the cornea), on the cornea, or on the conjunctiva. The bumps might persist anywhere from a few days to two weeks. These lumps on the conjunctiva develop into open sores (ulcers) that heal without leaving a scar. Redness of the eye, impaired vision, heightened sensitivity to strong light, a sense of a foreign object trapped in the eye, and sometimes visible flak are other common symptoms.


An eye examination by a doctor

The characteristic look of the eyes is used to diagnose phlyctenular keratoconjunctivitis.

Some persons may be tested for TB by doctors


Eye drops containing corticosteroids and antibiotics

Eyelid washes can help with seborrheic blepharitis.

People with blepharitis caused by seborrheic dermatitis (seborrheic blepharitis) should scrape the margins of their eyelids gently to help prevent the illness from returning (see Treatment of Blepharitis)
