Synonyms and keywords: Conjunctivitis in kids
Overview
Conjunctivitis is characterized by inflammation and swelling of the conjunctival tissue which can be associated with engorgement of the blood vessels, ocular discharge, and pain. Neonatal conjunctivitis is a red eye in a newborn caused by infection, irritation, or a blocked tear duct. When caused by an infection, neonatal conjunctivitis can be very serious.
Historical Perspective
- Neonatal conjunctivitis was first described by S.T. Quellmaz in 1750.[1][2]
- Crédé introduced 2% silver nitrate for the first time as a prophylaxis treatment method for conjunctivitis in the newborns in 1881. In 1883, Koch discovered the bacilli of two different forms of infectious conjunctivitis.
- In 1953, Micheal Hogan first described the association between atopic dermatitis and conjunctivitis.
Classification
Conjunctivitis can be classified into subtypes:[3]
- Bacterial conjunctivitis
- Viral conjunctivitis
- Allergic conjunctivitis
- Chemical conjunctivitis
- Immune mediated conjunctivitis
Pathophysiology
- The surface tissues of the eye and the ocular adnexa are colonized by normal flora such as streptococci, staphylococci and corynebacteria. Alterations in the bacterial titer, or in the species of bacteria can lead to clinical infection. Alteration in the flora can also result from external contamination, the use of topical or systemic antibiotics, or spread from adjacent infectious sites.
- Disruption of defense barriers can lead to infection. The primary defense against infection is the epithelial layer covering the conjunctiva. Secondary defense include hematologic immune mechanisms carried by the conjunctival vessels, tear film immunoglobulins and lysozyme and the rinsing action of lacrimation and blinking.[4]
Causes
- Conjunctivitis in children[5][6]
Differentiating conjunctivitis from other Diseases
In children with red eye and conjunctivitis symptoms, mentioned diagnosis should be excluded:[7]
- Corneal abrasion
- Subconjunctival haemorrhage
- Blepharitis
- Periorbital cellulitis
- Uveitis
- Episcleritis
Epidemiology and Demographics
- Bacterial conjunctivitis predominantly occurs in children <6 years of age. Recent studies have confirmed that haemophilus influenzae and streptococcus pneumoniae are the two organisms most commonly responsible for bacterial conjunctivitis in children.
- Viral conjunctivitis occurs most often in the fall and winter and usually affects children older than 6 years.
- Boys and girls are affected in similar proportions.[5]
Risk Factors
Risk factors of neonatal conjunctivitis includes:[8][9]
- STDs in mother
- HIV infected mothers
- Exposure of the infant to infectious organisms
- Prematurity
- Poor hygienic delivery conditions
- Ocular trauma during delivery
Natural History, Complications and Prognosis
Natural history
- Chlamydial conjunctivitis is cuased by chlamydia trachomatis which is one of the most common causes in neonatal conjunctivitis. Women with untreated chlamydia can pass the bacteria to her baby during childbirth. Symptoms include red eye, swelling of the eyelids, and purulent discharge. Symptoms are likely to appear 5 to 12 days after birth. About half ofnewborns with chlamydial conjunctivitis also have the infection in other parts of their bodies.[10][2][5]
- Gonococcal conjunctivitis is caused by neisseria gonorrhoeae. Women with untreated gonorrhea can pass the bacteria to her baby during childbirth. Symptoms usually include red eye, thick pus in the eyes, and swelling of the eyelids. This type of conjunctivitis usually begins about 2 to 4 days after birth. It can be associated with bacteremia and meningitis in newborns.
- Chemical conjunctivitis can occurs when eye drops are given to newborns or children to help prevent a bacterial infections. Symptoms of chemical conjunctivitis usually include mildly red eye and some swelling of the eyelids. Symptoms are likely to last for only 24 to 36 hours.
- Conjunctivitis caused by adenovirus is frequently hemorrhagic, and cases of adenovirus keratoconjunctivitis are often accompanied by dramatic degrees of periorbital swelling.
Complications
Complications to neonatal conjunctivitis include:[11][12]
- Pseudomembrane formation
- Corneal edema
- Peripheral pannus formation
- Corneal opacification
- Corneal perforation
- Endophthalmitis
- Loss of eye and blindness
- Infantile pneumonia
- Nasopharyngeal, rectaland vaginal colonization
- Some systemic complications particularly in gonococcal conjunctivitis including:
- Stomatitis
- Arthritis
- Rhinitis
- [Septicemia]]
- Meningitis
Complications of viral conjunctivitis in children including:[2]
- Keratitis
- Corneal ulceration with keratoconjunctivitis
Prognosis
- Early detection and early treatment of extremely pathogenic bacteria, such as Chlamydia trachomatis or Neisseria gonorrhoeae, is associated with a good prognosis. [2]
Diagnosis
Diagnostic Criteria
- Redness, excessive tearing, and irritation are symptoms common to all forms of conjunctivitis. Photophobia, itching, mucopurulent or non-purulent discharge, chemosis, burning eyes, blurred vision and eyelid swelling are variable depending on the pathogen. Broad generalizations can be made about the clinical characteristics of bacterial conjunctivitis as compared to viral conjunctivitis but distinguishing them clinically in individual children may be difficult.[13]
Symptoms
Gonococcal Conjunctivitis
Gonococcal conjunctivitis is more severe than chlamydial conjunctivitis. The incubation period is 2-5 days and it is usually bilateral.[2]
Chlamydial conjunctivitis
Chlamydial conjunctivitis has a later onset than gonococcal conjunctivitis. The incubation period is 5-14 days. Most of the cases are mild and self-limited, but occasionally may be severe.[2]
Chemical conjunctivitis
Chemical conjunctivitis usually occurs within 24 hours of instillation of silver nitrate solution and resolves spontaneously within a few days.[3]
Herpes simplex keratoconjunctivitis
Herpes simplex keratoconjunctivitis in an infant usually presents with generalized herpes infection.[3]
Bacterial Conjunctivitis
Bacterial conjunctivitis more than viral conjunctivitis tend to cause bilateral rather than unilateral involvement.[3]
- Mucopurulent discharge
- Eyelids swelling
- Red eye
Physical Examination
Ophthalmologic examination of children with conjunctivitis is usually remarkable for:[3][14]
- Chemosis
- Mucopurulent or watery discharge
- Eye lid oedema
- Mild to moderate hyperemia
