Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the transparent membrane (conjunctiva) that covers the white part of the eye. There are several types of conjunctivitis including viral, bacterial, allergic, and toxic. Symptoms include redness, tearing, irritation, and discharge from the eye. Treatment depends on the underlying cause but may include antibiotic eye drops, antiviral medication, or antihistamine eye drops. Good hygiene practices can help prevent the spread of contagious forms of conjunctivitis.

3. INTRODUCTION
The conjunctiva is a thin membrane that covers the
inner surface of the eyelid and the white part of the
eyeball(sclera)
Conjunctivitis is the inflammation of conjunctiva
Inflammation of the conjunctiva is called
conjunctivitis, which makes the white of the eye
appear red
6. DEFINITION
Conjunctivitis is an inflammation or infection of the
transparent membrane (conjunctiva) that lines the
eyelid and covers the white part of the eyeball
⚫When small blood vessels in the conjunctiva become
inflamed, they're more visible. This is what causes
the white of the eyes to appear reddish or pink
⚫Also known as “PINK EYE”
9. RISK FACTORS
Exposure to something for which the person have an allergy
(allergic conjunctivitis)
Exposure to someone infected with the viral or bacterial
form of conjunctivitis
Using contact lenses frequently
Microbial infection (Chlamydia), fungus etc.
11. TYPES OF CONJUNCTIVITIS
Viral and bacterial conjunctivitis:
Viral conjunctivitis and bacterial conjunctivitis may affect one
or both eyes
Viral conjunctivitis usually produces a watery discharge.
Bacterial conjunctivitis often produces a thicker, yellow-green
discharge
Both viral and bacterial conjunctivitis can be associated with
colds or with symptoms of a respiratory infection, such as a
sore throat
12. Viral and bacterial conjunctivitis:
Both viral and bacterial types are very contagious. They
are spread through direct or indirect contact with the eye
secretions of someone who's infected
Adults and children alike can develop both of these types
of pink eye. However, bacterial conjunctivitis is more
common in children than it is in adults
14. Allergic conjunctivitis
Allergic conjunctivitis affects both eyes and is a response
to an allergy-causing substance such as pollen
Most allergic conjunctivitis can be controlled with allergy
eyedrops
16. Toxic conjunctivitis
Toxic conjunctivitis typically occurs with constant use of
topical ocular medications
The reaction may take days to years to develop. There
also appears to be a dose-response effect with regard to
the preservative concentration and total amount of
preservative-containing medications used
It implies direct damage to ocular tissues from an
offending agent, usually a preservative or medication
18. PATHOPHYSIOLOGY
Microbes enter the eye on contact with infected objects
Inflammation of the eye
Dilatation of blood vessels of eye
Swelling, redness, exudates and discharge
19. SIGN AND SYMPTOMS
Tenderness of the eye, or pain (which can be severe in the
cases of irritant conjunctivitis) & Swelling of conjunctiva
(chemosis)
Itchiness
Body aches
Photophobia
Redness of the eye or inner eyelids (hyperemia)
Discharge and tear (epiphora)
20. SIGN AND SYMPTOMS
Drooping of upper eye lid
Periorbital cellulitis
Fever
Sore throat
Runny nose
Swelling of the eyelids
Infection usually begins with one eye, but can quickly
spread to other eye in cases of viral or bacterial conjunctivitis
25. MEDICAL MANAGEMENT
The management of conjunctivitis depends on the type. Most
types of mild and viral conjunctivitis are self-limiting, benign
conditions that may not require treatment and laboratory
procedures
26. BACTERIAL CONJUNCTIVITIS
If the infection is bacterial, the doctor may prescribe
antibiotic eye drops as pink eye treatment, and the infection
should go away within several days
Antibiotic eye ointment, in place of eye drops, is sometimes
prescribed for treating bacterial pink eye in children
An ointment is often easier to administer to an infant or
young child than are eye drops, though the ointment may blur
vision for up to 20 minutes after application
27. BACTERIAL CONJUNCTIVITIS
With either form of medication, expect signs and
symptoms to start getting better in a few days
Topical antibiotics
Fluoroquinolones, sodium sulfacetamide or
trimethoprim for 7 to 10 days
28. VIRAL CONJUNCTIVITIS
There is no treatment for most cases of viral conjunctivitis.
Instead, the virus needs time to run its course — up to two
or three weeks
Viral conjunctivitis often begins in one eye and then infects
the other eye within a few days. The signs and symptoms
should gradually clear on their own
Antiviral medications may be an option if the doctor
determines that the viral conjunctivitis is caused by the
HERPES SIMPLEX VIRUS
29. ALLERGIC CONJUNCTIVITIS
If the irritation is allergic conjunctivitis, the doctor may
prescribe one of many different types of eye drops for people
with allergies
These may include medications that help control allergic
reactions, such as antihistamines or drugs that help control
inflammation, such as steroids and anti-inflammatory drops
The patient may also reduce the severity of allergic
conjunctivitis symptoms by avoiding whatever causes the
allergies when possible
30. LIFESTYLE AND HOME REMEDIES
Apply a hot compress to the eyes
Try eye drops
Stop wearing contact lenses
Reduce exposure to light
Prevent rubbing of the eye
Clean the eye using sterile water and cotton swabs, from inner
canthus to outer canthus
Use of dark sunglasses is advised, in presence of photophobia
31. PREVENTION
Practice good hygiene to control the spread of pink eye. For
instance:
Don't touch your eyes with your hands
Wash your hands often
Use a clean towel and wash cloth daily
Don't share towels or washcloths
Change your pillow cases often
Don’t use eye cosmetics
Don't share eye cosmetics or personal eye care items
Although pink eye symptoms may resolve in three or four days,
children with viral conjunctivitis may be contagious for a week or
more. Children may return to school when they no longer
experience tearing and redness of eyes
