Conjunctivitis is an inflammation or swelling of the conjunctiva. The conjunctiva is the thin transparent layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye. Often called "pink eye".

2. Definition
The conjunctiva is a thin membrane that
covers the inner surface of the eyelid and
sclera
The conjunctivitis is an inflammation of
the conjunctiva, which eye appear red
with or without discharges.

14. 2. Viral Conjunctivitis
• Usually benign and self-limited, (longer course approximately 2-4 weeks)
• Is highly contagious.
• Avoid touching their eyes, shaking hands, and sharing towels, among other
activities.
• Transmission; accidental inoculation of viral particles from the patient's hands
or by contact with infected upper respiratory droplets, fomites, or contaminated
swimming pools.
• Common External Ocular infection.
• In 90% cases, Adenovirus is the causative agent.
• May be Sporadic, or occur in epidemics.

15. • Adenovirus conjunctivitis(>90% cases).

• Parammyxovirus conjunctivitis.
• ARBOR virus conjunctivitis
Causative agents

16. Spread of infection
Facilitated by
• Virus can survive on dry surfaces for weeks.
• Viral shedding may occur for many days before clinical features are apparent.
Transmission by
• Contact with Respiratory or ocular secretions.
• Via Contaminated Fomites such as Towels.
• Route of transmission is usually Eye-Hands-Eyes.
• In Clinical setting,Eye-Instruments-Eye.

17. Presentation
Epidemic Keratoconjunctivitis
• Most severe presentation.
• Caused by adenoviruses type 8,19 and 37.
• Markedly contagious.
• incubation period after infection (8 days) & virus shed from the inflamed eye for
2-3 weeks.
• Keratitis occurs in 80% cases.
Non-specific acute follicular Conj.
• Most common form of acute follicular conjunctivitis
• Caused by adenovirus serotypes 1 to 11 & 19
• Milder form of acute follicular conjunctivitis.
• Unilateral symptoms, Other eye involved 1-2 days later, but less severely.
• Patient may have systemic symptoms such as sore throat or common cold.

18. Pharyngoconjunctival fever
• Adenoviral infection commonly associated with subtypes 3,4 & 7.
• Acute follicular conjunctivitis, associated with pharyngitis.
• Fever & pre-auricular lymphadenopathy.
• Cornea : superficial punctate keratitis. (30%)
Chronic/relapsing adenoviral conj.
• Rare
• Gives a clinical picture of chronic non-specific
• Follicles/papillas.
• Can persist over years, but eventually self limiting.

19. Clinical features
Symptoms
• Watering
• Redness
• Irritation.
• Itching.
• Photophobia (When Cornea is involved).
Signs
• Eyelids Edema, Ranging from mild to Severe.
• Lymphadenopathy Tender Pre-auricular nodes (common).
• Conjunctiva Hyperemia, Follicles. May be Papillae (Particularly superior tarsal
conjunctiva).
• Severe Inflammation: may be associated with conjunctiva Hamorrhages,
chemosis, membranes (Rare) and pseudomembranes. Sometimes conjunctiva
Scarring.
• Keratitis (Adenoviral): PEK Usually occur in 7-10 days of onset of symptoms.
Resolving in 2 weeks.
• Anterior Stromal infiltrates/SEI: may persist for months or years.
• Anterior uveitis: Usually mild.

21. Herpes simplex Virus
• Causes Follicular conjunctivitis particularly in primary disease.
• Usually unilateral.
• Often Associated skin lesions.
• Micro dendrites may be mistaken for punctate epithelial keratitis, But Corneal
sensation is reduced in HSV
Acute hemorrhagic conjunctivitis
• Usually occurs in tropical areas.
• Caused by Enterovirus and coxsackie virus (Picornavirus family).
• Rapid onset, resolves within 1-2 weeks.

22. Treatment
Approach Considerations
Treatment of adenoviral conjunctivitis is supportive.
Symptomatic Treatment
Cold compresses and lubricants, such as artificial tears, for comfort.
Topical vasoconstrictors and antihistamines.
Antibiotic and Topical Steroid Treatment

27. • Recurrent, Bilateral, self limiting allergic inflammation of the conjunctiva
affecting children and young adults

important role
2. Vernal Keratoconjunctivitis (VKC)
Symptoms

• Intense ocular itching, Lacrimation,
Photophobia, blepharospasm, blurred vision, FB
sensation, burning and difficulty opening eyes in
the morning.
• Thick mucous discharge, Pseudoptosis due to
large papillae.
• Giant papillae on the superior Palpebral
conjunctiva are the clinical hallmark.

28. VKC types

29. VKC types

30. VKC types

31. Treatment
• Topical antihistamine
• Mast cell stabilizers: sodium chromoglycate 2 % drops 4-5 times/day
• Topical steroid: Every 4 hrs. for 2 days followed by 3-4 times a day for 2
weeks .
MONITOR IOP TO PREVENT STEROID INDUCED GLAUCOMA
• Acetyl cysteine (0.5%)
• Systemic :
I. Oral antihistamine : for itching
II.Oral steroid : short course for very severe non responsive case
• Treatment of large papilla supratarsal injection of long acting steroid or
surgical removal
• General measures: dark goggles, cold compress, change of place from hot
to cold

32. 3. Atopic Keratoconjunctivitis (AKC)

33. Symptoms
• Itching
• Soreness
• Dry sensation
• Mucoid discharge
• Photophobia
Signs
• Lid margins: inflamed with round posterior borders
• Conjunctiva : inferiorly involve, watery discharge, milky appearance, very fine
papilla, hyperaemia scarring with shrinkage
• Limbal: limbal involvement similar to limbal VKC
• Cornea; punctate epithelial keratitis in lower half, vascularization , plaque

35. Treatment
• Topical antihistamine
• Mast cell stabilizers: sodium chromoglycate 2 % drops 4-5 times/day
• Topical steroiD
• Supratarsal steriod injection in severe
• Others:
!treat facial eczema and lid margin disease
!Immunosuppressive agents( cyclosporine, tacrolimus)

36. 4. Giant Papillary Conjunctivitis

37. SYMPTOMS AND SIGNS
Thick mucous discharge, inflamed superior papillae and blurry vision, FB
sensation, redness – GPC staging
• Stage 1: itching and decreased lens tolerance
• Stage 2: blurred vision, superior tarsal papillae ( >0.3mm)
• Stage 3: excessive contact lens movement because tarsal papillae don’t allow
smooth movement of lid .
• Stage 4: similar appearance to mild VKC
