a) Definition
of Conjunctivitis
Conjunctivitis is an inflammation of the
conjunctiva, a protective membrane that covers the visible white area of the
eye and the inner side of the eyelid. Inflammation causes the afflicted eye(s)
to turn red and can be caused by a number of circumstances. Germs such as
viruses or bacteria (infectious conjunctivitis), allergies (allergic
conjunctivitis), dust or dirt, dry air, irritating liquids, or conjunctival
injury are examples of these. Conjunctivitis can occur when the eye is not
maintained moist enough with tear fluid.
b) Key Numerical Statistics on Conjuctivitis
According to one study, the yearly incidence
rate in the United States is 135 per 10,000 people. Conjunctivitis is the most
prevalent ocular ailment identified in emergency departments (EDs) in the
United States, accounting for over one-third of all eye-related visits. From
2010 to 2013, there were 555,740 visits in US emergency departments that
resulted in a main diagnosis of conjunctivitis. Conjunctivitis accounts for 1%
to 2% of primary care visits in the United States, and the majority of cases
are caused by a viral infection. Bacterial keratitis, a more severe type of
bacterial conjunctivitis, is estimated to affect 10 to 30 contact lens wearers
per 100,000. Non-ophthalmologists, such as internists, primary care doctors,
pediatricians, and nurses, diagnose more than 80% of all acute cases.
These figures demonstrate the prevalence of
conjunctivitis and its impact on the healthcare system. It's crucial to
remember that these figures might fluctuate depending on characteristics
including age, gender, and time of year. For example, children under the age of
seven had the greatest rates of diagnosis, with the peak prevalence happening
between the ages of 0 and 4 years. The second peak of the distribution comes
when women are 22 years old and males are 28 years old.
2) Types of
Conjunctivitis
Staphylococcus aureus,
Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis,
Chlamydia trachomatis, and Neisseria gonorrhoeae are among the microorganisms
that cause bacterial conjunctivitis. It is transmitted by hand-to-eye or
hand-to-nose contact, and it can also be caused by incorrect contact lens
usage. A red, irritated, or painful eye with a thick, yellow discharge (pus) is
one of the symptoms. Antibiotic drops are often used to shorten the duration of
the infection and limit the risk of it spreading to others.
Viral conjunctivitis, which
accounts for over 80% of all conjunctivitis instances, is caused by a variety
of viruses, including adenovirus, which causes the common cold. It spreads
readily from person to person by contact. Red, stinging eyes with watery
discharge are symptoms. It usually begins in one eye but can spread to both.
There is no particular therapy for viral infections; the virus must be cleared
by the immune system, which generally takes a week or two. Artificial tears,
cold compresses, and antihistamines can provide symptomatic relief.
Allergens and irritants such as
pollen, dust, and mold induce allergic conjunctivitis. It might be seasonal, as
in seasonal allergies, or perpetual, as in it lasts all year and is usually
caused by indoor allergens such animal dander, dust, and mold spores. Eye
irritation, redness, watery or white, stringy mucous discharge, and swollen
eyelids are all symptoms. Cold compresses, artificial tears, anti-allergy eye
drops or oral medicines, and allergy immunotherapy may be used in treatment.
d) Toxic or Chemical Reaction
Conjunctivitis
Chemical or toxic reaction When
the eye is exposed to certain chemicals or irritants, conjunctivitis develops.
In the conjunctiva, the poisonous substance might elicit a papillary or
follicular reaction. The particular symptoms and therapy might differ based on
the hazardous chemical involved.
e) Conjunctivitis related to Contact Lens
Use
Contact lens-related
conjunctivitis can be caused by inappropriate lens care, such as not cleaning
the lenses correctly or using them for an extended period of time. This can
result in either bacterial or viral conjunctivitis. The symptoms are similar to
those of bacterial and viral conjunctivitis, and treatment consists of removing
the contact lenses and administering appropriate medicine if an infection is
present.
f) Conjunctivitis due to Foreign Body
A foreign body conjunctivitis arises
when an item or substance enters the eye and irritates the conjunctiva. This
can result in symptoms including redness, discomfort, and the sensation that
something is in the eye. The foreign body is removed, and lubricating eye drops
or antibiotics are used if an infection is present.
Factitious conjunctivitis is an
uncommon kind of self-inflicted conjunctivitis. It is frequently coupled with a
psychiatric problem in which the individual deliberately develops or feigns
medical symptoms. Symptoms and therapy may differ based on the acts made by the
individual to cause the disease.
Idiopathic conjunctivitis refers
to conjunctivitis that has no identified etiology. Doctors are often unable to
pinpoint the source of inflammation despite comprehensive examination and
testing. Treatment often consists of symptom management with lubricating eye
drops and cold compresses, as well as monitoring the disease for any changes
that may indicate a particular cause.
3) Etiology and Risk Factors of Conjuctivitis
i) Viral Conjunctivitis
The most frequent cause of
conjunctivitis is viral conjunctivitis, which accounts for up to 75% of cases.
It is extremely infectious and is caused by a variety of viruses, including
adenoviruses, rubella virus, rubeola (measles) virus, herpesviruses (including
herpes simplex virus and varicella-zoster virus), and picornaviruses (including
coxsackievirus A24 and enterovirus 70). Hand-to-eye contact, airborne
transmission, and reservoirs such as swimming pools are all ways for the virus
to spread. For 10-14 days, most instances of viral conjunctivitis are extremely
infectious.
ii) Bacterial Conjunctivitis
Bacterial conjunctivitis is
caused by bacteria such as Haemophilus influenzae, Streptococcus pneumoniae,
Moraxella catarrhalis, Chlamydia trachomatis, Staphylococcus aureus, and
others. It can be transmitted from person to person by hand-to-eye contact, eye
contact with infected items, sexual experiences including eye-to-genital
contact, or vertically from mother to infant. Bacteria can potentially spread
by big droplets in the respiratory system. Conjunctivitis can also be caused by
changes in the normal bacteria that dwell on the conjunctiva.
i) Allergic Conjunctivitis
Allergic conjunctivitis is a
reaction to an allergen, such as pollen. Your body creates an antibody called
immunoglobulin E (IgE) in reaction to allergens. IgE causes specific cells in
the mucous lining of your eyes and lungs to produce inflammatory compounds such
as histamines. This can cause a variety of allergic reactions, including red or
pink eyes.
ii) Toxic Conjunctivitis
Conjunctivitis is also related
with irritation from a chemical splash or foreign item in your eye. Flushing
and wiping the eye to remove the chemical or object might produce redness and
discomfort.
c) Risk Factors for Viral and Bacterial
Conjunctivitis
Not washing your hands before
touching your eyes, putting contaminated tissues and towels on your face and
eyes, wearing infected eye makeup, not cleaning contact lenses or wearing ones
that do not fit, and close contact with others are all risk factors for viral
and bacterial conjunctivitis.
Contact lens users are more
likely to get bacterial keratitis if they have bacterial conjunctivitis. They
should be instructed to remove their contact lenses, treated with topical
antibiotics, and assessed by an ophthalmologist as soon as possible.
Bacterial conjunctivitis is less
frequent in adults than viral conjunctivitis. The most prevalent pathogens
cause bacterial conjunctivitis in adults are Staphylococcus species, followed
by Streptococcus pneumoniae and Haemophilus influenzae. Bacterial conjunctivitis
is more frequent in children than viral conjunctivitis and is caused mostly by
H influenzae, S pneumoniae, and Moraxella catarrhalis.
Children are more susceptible to
viral illnesses than adults, whereas adults are more sensitive to bacterial
infections. Direct contact with the virus, airborne transmission, and
reservoirs such as swimming pools can all cause viral conjunctivitis.
Conjunctivitis, often known as eye flu or pink eye, cannot be contracted merely
by gazing into someone's eyes. Conjunctivitis is often communicated by direct
touch, rather than through light rays or simple eye contact. Conjunctivitis is
mostly transmitted by direct contact with discharge from an infected person's
eyes. The virus, for example, can spread if you touch your eyes after coming
into contact with an infected person's eye secretions.
While recent research has
revealed that conjunctivitis can be transferred by airborne particles, such as
when an infected person coughs or sneezes, this is not the predominant
mechanism of transmission. It is also worth noting that not all types of
conjunctivitis are infectious. Pink eye is caused by irritants or allergies
that are not communicable.
d) Conjunctivitis and New Covid Variant
Conjunctivitis, often known as
pink eye, has been discovered as a symptom of a novel COVID-19 variety,
especially the XBB.1.16 strain, also known as "Arcturus". This
variety is a subvariant of the extremely infectious Omicron variant, which has
been quickly spreading across the United States and other nations. According to
the Centers for Disease Control and Prevention (CDC), the incidence of this
variation has increased, particularly among travelers. As of April 22, 2023,
the CDC stated that Arcturus accounted for 9.6% of all cases in the United
States. Arcturus has been designated as a "variant of interest" by
the World Health Organization. Conjunctivitis has been identified as a COVID-19
symptom in youngsters. Conjunctivitis, on the other hand, is a frequent ailment
that can be caused by a variety of reasons, including other viruses, bacteria,
allergies, and irritants. As a result, the appearance of conjunctivitis may not
always imply a COVID-19 infection. If conjunctivitis is accompanied by
additional COVID-19 symptoms, such as fever or cough, or if the patient has
been exposed to the virus, COVID-19 testing should be investigated. It's also
worth mentioning that, while conjunctivitis can be painful, it's usually self-limiting
and doesn't require any special treatment. However, if symptoms last more than
a week or there are questions regarding the origin of the conjunctivitis, it is
best to seek medical attention.
Conjunctivitis has been
discovered as a symptom of the novel COVID-19 variation Arcturus, however it is
not exclusive to this variant and can be caused by a variety of other reasons.
As a result, the appearance of conjunctivitis may not always imply a COVID-19
infection. If you have other symptoms of COVID-19 or have been exposed to the
virus, you should get tested for it.
4) Clinical Presentation and Symptoms of Conjunctivitis
Conjunctivitis, sometimes known
as pink eye, is an inflammation of the conjunctiva, the clear membrane that
borders the eyelids and the eyeball. A viral or bacterial infection, an
allergic response, or discomfort from a chemical splash or foreign item in the
eye can all cause it.
General symptoms of
conjunctivitis include
- Redness in one or both eyes
- Itchiness in one or both eyes
- A gritty feeling in one or both eyes
- A discharge in one or both eyes that forms a crust, especially after sleep
- Increased tear production
- Swelling of the conjunctiva and/or eyelids
- Feeling like a foreign body is in the eye(s) or an urge to rub the eye(s)
- Burning sensation in the eyes
- Blurred vision
- Sensitivity to light
b) Specific Symptoms related to different
types of Conjunctivitis
i) Viral Conjunctivitis
The most prevalent kind of
conjunctivitis is viral conjunctivitis, which is frequently caused by
adenoviruses. It is extremely infectious and frequently spreads in schools and
other crowded settings. Among the specific symptoms are
- Usually begins in one eye and may spread to the other eye within days
- Discharge from the eye is usually watery rather than thick
- Can occur with symptoms of a cold, flu, or other respiratory infection
- Burning, red eyes with a watery discharge
ii) Bacterial Conjunctivitis
Staphylococcus aureus,
Staphylococcus epidermidis, or Streptococcus pneumonia are the most common
bacteria that cause bacterial conjunctivitis. It is very infectious and can be
fatal in newborns or persons with compromised immune systems. Among the
specific symptoms are
- More commonly associated with discharge (pus), which can lead to eyelids sticking together
- Sometimes occurs with an ear infection
- Pinkness or redness of the eye
- Burning, itching, a sensation of grittiness, or mild pain or discomfort in the eye
- Thick, sticky discharge from the eye
- Swollen and/or reddened eyelids
iii) Allergic Conjunctivitis
Allergens and irritants such as
pollen, dust, and mold induce allergic conjunctivitis. It is not contagious and
is classified into two types: seasonal allergic conjunctivitis, which is
associated with seasonal allergies, and perennial allergic conjunctivitis,
which lasts all year and is usually caused by indoor allergens. Among the
specific symptoms are
- Usually occurs in both eyes
- Can produce intense itching, tearing, and swelling in the eyes
- May occur with symptoms of allergies, such as an itchy nose, sneezing, a scratchy throat, or asthma
- Intense itching of eyes and urge to rub eyes
- Watery or white, stringy mucus discharge
- Swollen eyelids
iv) Conjunctivitis Caused by Irritants
Conjunctivitis can also be caused
by irritation from a chemical splash or foreign item in the eye. Symptoms such
as watery eyes and mucus discharge normally go away on their own after
approximately a day. If flushing does not relieve the symptoms, or if the
chemical is caustic, such as lye, get medical assistance as soon as possible.
5) Diagnosis for Conjunctivitis
a) Clinical Examination of Conjunctivitis
A detailed patient history and
physical examination are required for the clinical assessment of
conjunctivitis. The patient's history can reveal important details such as
probable exposure to infectious agents or allergens, recent upper respiratory
tract infections, use of antibiotics or immunosuppressive medicines, and any
recent contact with others who have conjunctivitis.
During the physical examination,
the healthcare professional will search for common conjunctivitis signs and
symptoms. These include eye redness or swelling, as well as the kind of ocular
discharge. A watery discharge, for example, is frequently linked with viral
conjunctivitis, but a thick discharge may indicate bacterial conjunctivitis.
To study the eye in depth, the
healthcare professional may also utilize a slit lamp, which is an instrument
that comprises of a microscope and a high-energy beam of light. This can aid in
identifying any damage to the eye's surface and determining the amount of the
inflammation.
b) Diagnostic Tests for Conjunctivitis
While conjunctivitis is
frequently diagnosed based only on the patient's history and physical
examination, some diagnostic procedures can assist confirm the diagnosis and
determine the cause. These tests are not frequently performed, but they may be
utilized in some circumstances, such as when determining the etiology of
conjunctivitis based on symptoms alone, or when the conjunctivitis is severe or
does not respond to first therapy.
One such test includes taking a
sample of infectious ocular discharge and submitting it to a laboratory for
examination. This can aid in determining if the conjunctivitis is the result of
a virus, bacteria, or allergy.
Polymerase chain reaction (PCR)
testing, which utilizes DNA from a sample to determine the presence of an
infection, and culture tests, which may identify the pathogenic bacterium and
test its susceptibility to different antibiotics, are two more tests that may
be employed.
c) Differential Diagnosis of Conjunctivitis
Other illnesses that might cause
similar symptoms are considered in the differential diagnosis of
conjunctivitis. Other types of conjunctivitis (such as allergic conjunctivitis)
are also included, as are conditions such as nasolacrimal duct obstruction,
pharyngoconjunctival fever, nongranulomatous anterior uveitis, HSV
keratoconjunctivitis, VZV keratoconjunctivitis, ocular chlamydial infections,
vernal keratoconjunctivit
To differentiate between these
disorders and reach a definitive diagnosis, the healthcare professional will
utilize the patient's history, physical examination findings, and the results
of any diagnostic testing.
6) Treatment for Conjunctivitis
The overall strategy to treating
conjunctivitis, regardless of the etiology, is to manage symptoms and prevent
the infection from spreading. This can be accomplished by using cold compresses
and artificial tears, both of which are available without a prescription over
the counter. It is also advised to refrain from wearing contact lenses until
the symptoms of conjunctivitis have totally resolved.
If the symptoms of conjunctivitis
do not improve within two days of receiving good supportive care, a topical
antibiotic is prescribed. However, antibiotics are not always required for the
clearance of bacterial conjunctivitis, and their usage should be carefully
examined to prevent contributing to antibiotic resistance.
b) Treatment for Bacterial Conjunctivitis
Mild bacterial conjunctivitis may
improve without antibiotics and without creating issues. It usually improves in
2 to 5 days without therapy but might take up to 2 weeks to entirely disappear.
However, antibiotics may be administered if the symptoms are severe or the
patient's immune system is impaired. These are often administered topically as
eye drops or ointment. Antibiotics may help decrease the duration of the
illness, reduce complications, and prevent the infection from spreading to
others.
c) Treatment for Viral Conjunctivitis
Viral conjunctivitis is usually
self-limiting, meaning it will go away on its own. The infection normally
clears up in 7 to 14 days, although it might take 2 to 3 weeks or more in
certain cases. The goal of viral conjunctivitis treatment is to provide
symptomatic relief, which can be accomplished by the use of artificial tears
for lubrication, cold compresses for comfort, and antihistamines for irritation
and redness.
A doctor can prescribe antiviral
treatment for more severe cases of conjunctivitis, such as those caused by the
herpes simplex virus or varicella-zoster virus. Antibiotics, on the other hand,
will not help viral conjunctivitis since they are ineffective against viruses.
d) Treatment for Allergic Conjunctivitis
Allergic conjunctivitis normally
improves if the allergen is removed from the person's surroundings. Allergy
drugs and specific eye drops (topical antihistamines and vasoconstrictors),
including certain prescription eye drops, can help alleviate allergic
conjunctivitis. In rare circumstances, a medication cocktail may be prescribed
to alleviate symptoms.
Avoiding allergens, wiping your
face after exposure to environmental allergens such as dust or pollen, regular
washing of clothes, bathing or showering before night, and keeping contact
lenses and cases clean are other actions that may be beneficial.
7) Home remedies for Conjunctivitis
Allergies, viruses, or bacteria
can all cause conjunctivitis, sometimes known as pink eye. While it usually
goes away on its own, there are a few home treatments that can help ease
symptoms and make you more comfortable. It is crucial to emphasize, however,
that these cures are not a substitute for expert medical advice and treatment,
particularly in severe situations or if symptoms continue.
a) Apply a compress: Soak a lint-free cloth in cool water, rinse it
dry, and gently apply it to your closed eyes. This can help relieve the
discomfort caused by conjunctivitis. You can also use a warm compress if you
like. If conjunctivitis affects only one eye, avoid rubbing both eyes with the
same towel to prevent the infection from spreading.
b) Eye Drops: Lubricating eye drops, commonly known as artificial
tears, are available over-the-counter and can alleviate itching and pain. These
drops can be especially beneficial if your conjunctivitis is caused by
allergies, since they can help clean the eye and eliminate allergy residues.
c) Pain-Relieving Medication: Ibuprofen and other over-the-counter
pain medicines can aid with inflammation and discomfort.
d) Avoid Contact Lenses and Eye Makeup: If you wear contact lenses,
you should cease using them until your conjunctivitis has cleared up. To avoid
re-infection, you may need to replace your lenses and case thereafter. Also,
avoid wearing eye makeup until the symptoms have subsided.
e) Good Hygiene Practices: Wash your hands frequently and avoid
touching your eyes to prevent the infection from spreading. Change or wash
bedding, such as pillowcases, sheets, and comforters, on a regular basis. Use
clean towels and wash dirty towels in hot water.
f) Avoid Allergens: If allergies are causing your conjunctivitis,
attempt to avoid the allergen causing the response. This might include staying
indoors when pollen counts are high or avoiding certain pets or dust.
Remember that these therapies are
intended to relieve symptoms rather than cure the ailment. It is critical to
get medical assistance if your symptoms persist or worsen. A doctor may give
antibiotic eye drops in some circumstances, such as bacterial conjunctivitis.
It's also worth noting that many home cures, such as utilizing breast milk or herbal
extracts, are not advised owing to a lack of scientific proof and potential
hazards.
8) Prevention and Management of Conjunctivitis
The preventive measures for
conjunctivitis include
i) Hand washing on a regular basis: Hand washing with soap and warm
water at least once a day can help prevent the spread of conjunctivitis.
ii) Avoid rubbing or touching your eyes: This has the potential to
aggravate the illness or transmit it to the other eye.
iii) Personal stuff should not be shared: Towels, cosmetics, and
contact lenses, for example, should not be shared since they can readily
transmit the illness.
iv) During an illness, avoid using contact lenses: Contact lenses
should not be used unless the eye doctor indicates it is safe to do so.
v) Allergens that induce symptoms should be avoided: Allergen
avoidance is a critical preventative step for allergic conjunctivitis.
b) Management of Conjunctivitis in
Different Settings
The management of conjunctivitis
varies depending on the type of conjunctivitis and the setting in which it is
being treated.
i) Viral Conjunctivitis: Most episodes of viral conjunctivitis are
mild and will go away on their own in 7 to 14 days. However, antiviral medicine
may be administered in rare circumstances to treat more severe types of
conjunctivitis.
ii) Bacterial Conjunctivitis: Mild bacterial conjunctivitis may
resolve without the use of antibiotics. Antibiotics, commonly administered
topically as eye drops or ointment, may be prescribed to assist minimize the
duration of the illness, reduce complications, and prevent the infection from
spreading to others.
iii) Allergic Conjunctivitis: This form of conjunctivitis normally
improves when the allergen is removed from the individual's surroundings.
Allergy drugs and certain eye drops can also help with allergic conjunctivitis.
Patient education is critical in
all settings to avoid transmission. It is critical to emphasize the importance
of hand cleanliness for patients, staff, family, and friends. Patients should
be told not to contact their eyes, shake their hands, share personal objects
like cosmetics or towels, and stay away from swimming pools when afflicted. Medical
devices must be sterilized, and patients hospitalized with active
conjunctivitis must be segregated.
9) Real Life Testimonials and Stories for Conjunctivitis
Suzanne Lescure was diagnosed
with ocular conjunctival melanoma, a rare kind of melanoma. Despite the
hardships and worry that her illness brought, she attributes her ability to
confront her diagnosis and subsequent treatments to a strong and supportive
family as well as a decent insurance coverage. She was granted a second shot at
life after undergoing multiple procedures, including the removal of her eye.
She now utilizes her experience to help others by speaking at nurse panels and
participating in a support group.
In one of his videos, YouTuber
Steve Marvell discussed his experience with conjunctivitis. He described how he
employed home medicines to treat or cure his conjunctivitis. He also discussed
his conjunctivitis experience and how it affected his profession and daily
life.
In December 2014, Jane Leahy was
diagnosed with acute myeloid leukemia. She had a terrible cold, sinusitis, and
conjunctivitis in the months preceding up to her diagnosis. Despite the
obstacles, she was able to reach remission and is now utilizing her experience
to assist others.
An anonymous person shared their
experience of contracting conjunctivitis following a sexual encounter. They
used Telehealth to confirm the diagnosis and were prescribed eye drops, and

about the unexpected infections that can result from sex.
10) Conclusion
Conjunctivitis, sometimes known
as "pink eye" or "red eye," is a common ailment that
involves inflammation of the conjunctiva, the thin tissue that extends from the
limbus of the eye to the edge of the eyelid. Various reasons, such as
allergies, irritants, mechanical abrasions, germs, and viruses, can cause it.
The illness is frequently self-limiting and produces no lasting eyesight loss
or structural harm.
Conjunctivitis is classified into
three types: allergic, viral, and bacterial. Allergic conjunctivitis is
characterized by watery discharge, chemosis, and conjunctival injection and is
frequently coupled with other atopic symptoms. Viral conjunctivitis, which is
most usually caused by adenoviruses, is extremely infectious and manifests as
red, itchy eyes with a watery or mucous discharge. Bacterial conjunctivitis
frequently mimics viral conjunctivitis but is characterized by a more
mucopurulent discharge.
While conjunctivitis is usually
not dangerous, determining the specific cause is critical to ensuring proper
treatment. Bacterial infections, for example, may necessitate the use of
antibiotic eye drops or ointment, whereas allergic conjunctivitis is normally
treated with antihistamine drops or pills. In most cases, viral infections
resolve on their own.
Regular hand washing, avoiding
direct contact with an infected person's ocular discharge, and using separate
towels to decrease the likelihood of infection transmission are all prevention
techniques. Contact lens wearers should change their lenses on a regular basis
and avoid using them when bathing or swimming.
To summarize, conjunctivitis is a
common yet treatable illness. It is critical to seek medical attention if
symptoms persist or worsen in order to receive appropriate treatment and
prevent the infection from spreading further. The risk of getting or
transmitting conjunctivitis can be considerably lowered with adequate care and
hygiene habits.

FAQ’s
Conjunctivitis, also known as
'Pink Eye' or 'Sore Eyes', is an inflammation of the 'Conjunctiva', a thin
tissue that covers your eyeball and the inside of the eyelid. The conjunctiva
may swell up because of an allergy, irritant or an infection, and its small red
blood vessels make it appear pink or reddish.
2) What are the symptoms of Conjunctivitis?
Symptoms include redness in the
white of the eye or inner eyelid, swollen conjunctiva, more tears than usual,
thick yellow discharge that crusts over the eyelashes, green or white discharge
from the eye, itchy eyes, burning eyes, blurred vision, and more sensitivity to
light.
3) How do you get Conjunctivitis?
Conjunctivitis could be due to
reasons like pollen, dust, pollution or even as a reaction to certain kinds of
eye drops or contact lenses. It could be caused by increased viral or bacterial
activity in your environment, a common phenomenon during seasons like the
monsoon. Conjunctivitis can also be caused as a result of chemical irritants or
due to STDs like herpes, chlamydia, and gonorrhoea.
4) Who can get Conjunctivitis?
Anyone can get conjunctivitis as
it is like a common cold but children are more prone to it because, at school,
they come in close contact with many others.

In an eye with pink eye, the
white part looks light pink to reddish and your eyelids are puffy or droopy.
You might see fluid (discharge) coming from the infected eye or crusting on
your eyelashes and eyelids
The pink or reddish color of pink
eye happens when the blood vessels in the membrane covering your eye (the
conjunctiva) gets inflamed, making them more visible. Causes of inflammation
include viruses, bacteria, allergens, and irritating substances
Treatment for pink eye caused by
allergies includes prescription or over-the-counter eye drops. These contain
either antihistamines to control allergic reactions or anti-inflammatory drugs
such as steroids or decongestants
14) Does pink eye go away on its own?
