Conjunctivitis From Wikipedia, the free encyclopedia. Conjunctivitis is an inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids), often due to infection. There are three common varieties of conjunctivitis, viral allergic , and bacterial . Viral and bacterial conjunctivitis are contagious. Other causes of conjunctivitis include thermal and ultraviolet burns, chemicals, toxins, overuse of contact lenses , foreign bodies, vitamin deficiency, dry eye , dryness due to inadequate lid closure, exposure to chickens infected with Newcastle disease , epithelial dysplasia (pre- cancerous changes), and some conditions of unknown cause such as sarcoidosis Blepharoconjunctivitis is the combination of conjunctivitis with blepharitis Keratoconjunctivitis is the combination of conjunctivitis and keratitis An eye with Viral conjunctivitis Contents Epidemiology Diagnosis Symptoms Signs ... edit Epidemiology Viral conjunctivitis is spread by aerosol or contact of a variety of contagious viruses, including many that cause the

Bacterial Conjunctivitis SIGNS AND SYMPTOMS Patients with bacterial conjunctival infections present with injection of the bulbar conjunctiva, episcleral vessels and perhaps papillae of the palpebral conjunctiva. The infection often starts in one eye, then soon spreads to the other. There will be thick mucopurulent discharge, and patients usually say that their eyelids and eyelashes are matted shut upon awakening. There may be mild photophobia and discomfort, but usually no pain. Visual function is normal in most cases. PATHOPHYSIOLOGY The eye has a battery of defenses to prevent bacterial invasion. These include bacteriostatic lysozymes and immunoglobulins in the tear film, the shearing force of the blink, the immune system in general, and non-pathogenic bacteria that colonize the eye and compete against external organisms that try to enter. When any of these defense mechanisms break down, pathogenic bacterial infection is possible. Invading bacteria, and the exotoxins they produce, are considered foreign antigens. This induces an antigen-antibody immune reaction and subsequently causes inflammation. In a normal, healthy person the eye will fight to return to homeostasis, and the bacteria will eventually be eradicated. However, an extra heavy load of external organisms can be too difficult to fight off, causing a conjunctival infection and setting the eye up for potential corneal infection. The most commonly encountered organisms are Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae and Pseudomonas aeruginosa. In cases of hyperacute bacterial conjunctivitis, the patient will present with similar signs and symptoms, albeit much more severe. The most common infectious organisms in hyperacute conjunctivitis are Neisseria gonorrhoeae and Corynebacterium diptheroides. There is more danger in hyperacute bacterial conjunctivitis as these organisms can penetrate an intact cornea.

Viral Conjunctivitis A Pseudomembrane in EKC Severe Follicular Reaction SIGNS AND SYMPTOMS Most viral infections produce a mild, self-limiting conjunctivitis, but some have the potential to produce severe, disabling visual difficulties. The two most common self-limiting forms of viral conjunctivitis are epidemic keratoconjunctivitis and pharyngoconjunctival fever. Pharyngoconjunc-tival fever (PCF) is characterized by fever, sore throat and follicular conjunctivitis. It may be unilateral or bilateral. It is caused regularly by adenovirus 3 and occasionally 4 or 7. Corneal infiltrates are rare. The disorder varies in severity but usually persists for four days to two weeks. While the virus is shed from the conjunctiva within 14 days, it remains in fecal matter for 30 days. Epidemic Keratoconjunctivitis (EKC) often presents as a bilateral, inferior, palpebral, follicular conjunctivitis, with epithelial and stromal keratitis. Subepithelial corneal infiltrates are much more common in EKC than in PCF and are typically concentrated in the central cornea. EKC is regularly caused by adenovirus types 8 and 19. The key clinical signs of both conditions include: conjunctival injection, tearing, serous discharge, edematous eyelids, pinpoint subconjunctival hemorrhages, pseudomembrane formation and palpable preauricular lymph nodes. In severe cases, conjunctival desiccation causes scarring and symblepharon formation (adherence of the bulbar and palpebral conjunctivas).

CONJUNCTIVITIS IN CHILDHOOD by Dr. Moshe Ipp What are the most common causes of conjunctivitis in childhood? Conjunctivitis is an inflammation of the conjunctiva which is usually caused by infection or allergy. It is frequently referred to as “pink eye” and is the most common acute eye disorder seen by primary care pediatricians and family physicians. What are the characteristics of allergic conjunctivitis? Allergic conjunctivitis is characterized by ocular redness and itching. Tearing (clear tears), crusting of the eye lids and photophobia may also be seen. The condition is often recurrent, and seasonal. Children who have allergic conjunctivitis often have a history of other atopic diseases, particularly allergic rhinitis, eczema or asthma. What are the characteristics of an infectious conjunctivitis? Infectious conjunctivitis may be bacterial or viral. Bacterial conjunctivitis is twice as common as viral conjunctivitis. Typically in bacterial conjunctivitis the eye is red, there is a purulent discharge, the affected child is often a pre-schooler and there may be an associated otitis media. In viral conjunctivitis there is redness, clear tearing or crusting, usually occurs in an older school age child, and is often associated with pharyngitis.

A variety of microorganisms may infect the conjunctiva. The most common organisms are viral, particularly those from the group known as adenoviruses. Bacterial infections are less frequent. Both viral and bacterial conjunctivitis are quite contagious, easily passing from one person to another, or from a person's infected eye to his uninfected eye. Fungal infections are rare and occur mainly in people who use corticosteroid eye drops for a long time and in eye injuries involving vegetable matter. Newborns are particularly susceptible to eye infections, which they acquire from organisms in the mother's birth canal (neonatal conjunctivitis (see

Examination discloses generalized injection of the conjunctiva, thinning out towards the cornea (localized inflammation suggests some other diagnosis such as a foreign body, episcleritis, or a viral or bacterial ulcer). Vision and pupillary reactions should be normal and the cornea and anterior chamber should be clear. Any discomfort should be temporarily relieved by instilling topical anesthetic solution. Deep pain, photophobia, decreased vision and injection more pronnounced around the limbus (ciliary flush) suggest more serious involvement of the cornea and iris. Different symptoms suggest different etiologies. Tearing, preauricular lymphadenopathy and upper respiratory symptoms suggest a viral conjunctivitis. Pain upon awakening with lid crusting and a copious purulent exudate suggests a bacterial conjunctivitis. Few symptoms upon awakening but discomfort worsening during the day suggests a dry eye. Little conjunctival injection with a seasonal recurrence of chemosis and itching, and cobblestone hypertrophy of the tarsal conjunctiva suggests allergic (vernal) conjunctivitis. Physical and chemical conjunctivitis, caused by particles, solutions, vapors, natural or occupational irritants that inflame the conjunctiva, should be evident from the history.

Tears help protect the conjunctiva by diluting bacteria and washing it away. Tears also contain enzymes and antibodies which kill bacteria. There are many causes of conjunctivitis. Viruses are the most common cause. Other types include bacterial, Chlamydial, fungal, and parasitic agents (rarely). Pink eye refers to a viral infection of the conjunctiva. These infections are very contagious, especially among children. The virus is similar to the type which cause the common cold. The key is handwashing to prevent spreading the virus.

Highlights General Info about Conjunctivitis Conjunctivitis better known as Red Eye, is redness and soreness of the clear layer covering called the conjunctiva which coats the white of the eye and the eye lids. Conjunctivitis is the most common eye disease in the western hemisphere and varies in severity from mild inflammation with tearing to a severe inflammation that causes tissue injury and tissue death. It is usually caused by allergies, bacteria, viruses, or chemicals. Bacterial conjunctivitis presents with a red eye, pus discharge, a gritty sensation, and occasionally sticking shut of the eyelids. Viral conjunctivitis follows an upper respiratory infection such as the common cold. Allergic Conjunctivitis nearly always presents with a primary complaint of itching. red eyes, and other allergic symptoms such as rhinitis (stuffy, runny nose), "scratchy" throat, and dry, hacking cough are commonly present. Viral and bacterial forms of conjunctivitis are highly contagious, and can spread among children very rapidly, sometimes causing local epidemics.

What infections cause pink eye and how are they treated? What noninfectious conditions cause pink eye? Pink Eye At A Glance What is "pink eye"? Pink eye or conjunctivitis refers to a redness or irritation of the membranes on the inner part of the eyelids and the membranes (conjuctiva) covering the whites of the eyes. These membranes react to a wide range of bacteria, viruses, allergy- provoking agents, irritants, and toxic agents, as well as to underlying diseases within the body. Viral and bacterial forms of conjunctivitis are common in childhood. Overall however, there are many causes of pink eye. These can be classified as either infectious or noninfectious. What infections cause pink eye and how are they treated? Viral Pink Eye The leading cause of a red eye is virus infection. Viral pink eye is usually associated with more of a watery discharge, not green or yellow in color, and is frequently associated with viral "cold-like" symptoms. The eyelids may be swollen. Sometimes looking at bright lights is painful. While viral pink eye, may not require an antibiotic, the doctor should see the child, as occasionally this form of pink eye can be associated with infection of the cornea, (the clear portion of the front of the eyeball). This infection must be correctly detected and treated. Viral pink eye is highly contagious.
