CONJUNCTIVITIS
The basic description of conjunctivitis is that it is an inflammatory response of the conjunctiva that manifests as discharge and hyperemia. Acute or chronic, infectious or non-infectious, conjunctivitis can occur.
• Chlamydia trachomatis serotypes A–C are linked to trachoma, a persistent conjunctivitis.
• Ophthalmia neonatorum is acute mucopurulent conjunctivitis that manifests within the first month of life; • Inclusion conjunctivitis is caused by sexually transmitted C. trachomatis strains (serotypes D through K) in young adults exposed to infected genital secretions or in their newborn offspring.
The incidence of epidemiology
• In the Netherlands, there have been reports of up to 13.9 instances of infectious conjunctivitis per 1000 persons-years seen by general practitioners.
• With a reported frequency of 6.2 per 1000 live births, Chlamydia spp. are the most prevalent infectious organisms that cause ophthalmia neonatorum in the United States.
• There are now three cases of gonococcal ophthalmia neonatorum for every 1000 live births, a significant decrease from the previous 100 cases.
The frequency
• In portions of Asia, the Middle East, sub-Saharan Africa, and northern Africa, endemic trachoma is the most preventable cause of blindness.
• Trachoma still affects Native American communities and immigrants from endemic locations in the United States.
• According to WHO estimates from 2003, trachoma caused 7.6 million blind or severely visually impaired persons worldwide.
• As a result of more hygienic circumstances, trachoma incidence and severity have declined globally in recent decades.
RISK ELEMENTS
Trachoma spreads from eye to eye by hands, flies, towels, and other contact. It is strongly associated with poverty, lack of access to water, and healthcare facilities.
OVERALL PREVENTION
• Promoting general hygiene practices reduces trachoma-related morbidity.
• All sexual partners must receive treatment for adult inclusion conjunctivitis; public health measures against trachoma include the widespread application of tetracycline or erythromycin ointment to children's eyes in endemic areas for 21–60 days, or intermittently, or single-dose oral azithromycin therapy.
• Patients with viral epidemic keratoconjunctivitis (EKC) should be advised to wash their hands frequently, refrain from touching their eyes, and refrain from sharing towels or pillows with others. • Applying erythromycin or tetracycline ointment within an hour of delivery significantly reduces the risk of developing chlamydial ophthalmia neonatorum.
Pathophysiology
A disturbance of the host defensive systems, such as abnormalities of the ocular surface, abnormalities of the tear film, or systemic immunosuppression, is part of the pathogenesis of bacterial conjunctivitis.
Ethiology
Causes of Infection
• Bacteria (including Streptococcus species, Staphylococcus species, Treponema pallidum, Haemophilus species, Neisseria gonorrhoeae, Chlamydia trachomatis, and Bartonella henselae).
Adenoviruses, Coxsackie virus, echoviruses, enteroviruses, and other viruses are examples of fungi.
• Parasites (Wuchereria bancrofti, Toxocara canis, Onchocerca volvulus, and Loa loa worm) • There are four patterns of viral conjunctivitis:
Adenovirus serotypes 8, 19, and 37 are the cause of EKC.
Adenovirus serotypes 3 and 8 cause pharyngoconjunctival fever, which is more prevalent in children.
Tropical areas are more likely to get acute hemorrhagic conjunctivitis, which is brought on by enterovirus type 70 and Coxsackie virus type A24.
In connection with systemic viral illnesses including influenza, mumps, and measles
• A conjunctival reaction may also be a part of HSV and VZV ocular involvement (see "Keratitis").
• In roughly 5–10% of patients with the systemic infection, cat scratch illness caused by Bartonella henselae can result in conjunctivitis, among other symptoms. Parinaud Oculoglandular Syndrome is the term used to describe ocular involvement.
COMMON CONNECTED CIRCUMSTANCES
• The most frequent conditions linked to viral EKC are an upper respiratory tract infection or the presence of ill contacts in the home.
• Adult inclusion conjunctivitis may be associated with a history of urethritis, vaginitis, or cervicitis.
History of Diagnosis
• Patients may have eyelid edema, conjunctival injection (red eye), crying, mucous or mucopurulent discharge, or a foreign-body sensation, depending on the pathogen causing the problem. There is very little pain and only a tiny loss of visual acuity.
• Within a day or two of exposure, signs of gonococcal bacterial conjunctivitis appear in both infants and sexually active young people. When the membranes tear too soon, the incubation time for gonococcal ophthalmia neonatorum may be shortened.
• In cases of viral EKC, one eye typically becomes affected first, followed by the second eye immediately after, after an incubation period of up to one week. Light sensitivity (photophobia), fluid discharge, and a slight foreign-body sensation are all brought on by EKC.
MEDICAL EXAMINATION
• Conjunctivitis's clinical manifestations and progression are
• affected by the infection that is causing the problem.
Typically, infectious conjunctivitis manifests as discharge, eyelid edema, and hyperemia. While bacterial and allergic conjunctivitis typically exhibit a papillary reaction, which is a lymphoid hyperplasia surrounding a vascular core, viral and chlamydial conjunctivitis typically manifest as a primarily follicular conjunctival reaction. Particularly in viral conjunctivitis, the cornea may become secondary, exhibiting superficial vascularization and inflammatory infiltrations.
Depending on the infection, secretions might range from serosanguineous to purulent. While N. gonorrhoeae produces a thick, abundant, yellow-green purulent discharge, bacterial infections typically produce more mucopurulent exudates.
Among the results are conjunctival membranes and pseudomembranes.
Preauricular lymphadenopathy is frequently seen in cases of inclusion conjunctivitis, gonococcal conjunctivitis, EKC, or HSV.
A mucopurulent discharge is frequently the result of neonatal chlamydial conjunctivitis, which typically manifests acutely (5–14 days postpartum).
An early follicular reaction in the conjunctiva is linked to both inclusion conjunctivitis and trachoma. Following follicular resolution in trachoma, subconjunctival scarring develops, which results in
loss of goblet cells that produce mucin, keratitis, entropion, and trichiasis.
• Acute unilateral follicular conjunctivitis with mucopurulent discharge is the hallmark of inclusion conjunctivitis in adults. If left untreated, conjunctivitis can be persistent and last for months.
• Conjunctival hyperemia, eyelid swelling, fever, granulomatous nodules on the palpebral or bulbar conjunctiva, and regional lymphadenopathy are the symptoms of Parinaud Oculoglandular Syndrome. Neuroretinitis is another possibility.
• Several nodular or ulcerative lesions of the palpebral conjunctiva, as well as regional lymphadenopathy, are symptoms of painful purulent conjunctivitis caused by F. tularensis.
TESTS FOR DIAGNOSIS AND INTERPRETATION
Imaging First Step
Infectious conjunctivitis does not respond well to any particular modality.
Follow-up and Particular Points to Remember
Conjunctivitis in adults, genital examination, and
Both the afflicted persons and their sexual partners should undergo testing for genital chlamydial infection.
Diagnostic Techniques and Other
• Only hyperacute cases that are suggestive of N. gonorrhoeae, as well as severe, chronic, or uncommon cases, require microbiologic study.
• Gram-stained smears should be supported by cultures on blood and chocolate agar. Gram-stained smears may show gram-negative intracellular diplococci in gonococcal conjunctivitis or sporadic tiny gram-negative coccobacilli in Haemophilus conjunctivitis.
• In cases of trachoma, serum or tears may exhibit antibodies against C. trachomatis. Although isolation in cell cultures, ELISA, immunofluorescent monoclonal antibody stains, or chlamydial PCR techniques are more sensitive, 10–60% of Giemsa-stained conjunctival smears in such populations contain intracytoplasmic chlamydial inclusions in epithelial cells.
• Giemsa- or immunofluorescence-stained smears, isolation in cell cultures, or more recent non-culture methods are used to detect chlamydiae in adult inclusion conjunctivitis.
• PCR methods can be used to identify the viruses that cause viral conjunctivitis.
DIFFERENTIAL DIAGNOSIS: Infectious conjunctivitis needs to be distinguished from non-infectious conjunctivitis and from other conditions that cause red eyes. In newborns, chlamydial conjunctivitis typically has a longer incubation period (5–14 days) than gonococcal conjunctivitis (1–3 days). Examples of these entities include dry eye disease, Stevens–Johnson’s syndrome, ocular cicatricial pemphigoid (OCP), allergic/atopic/vernal conjunctivitis, exogenous irritation from pollution and medications (medicamentosa), conjunctival or eyelid tumors, and graft-versus-host disease.
FIRST LINE TREATMENT MEDICATION
• The only supportive care needed for viral conjunctivitis is the use of cold compresses and artificial tears. A topical steroid (loteprednol 0.5% q.i.d.) may be recommended if membranes or pseudomembranes are present and can be peeled off.
• To prevent corneal epithelial damage, topical antiviral treatment (trifluridine 1% five times a day) is used to treat HSV conjunctivitis. Topical steroids should not be used.
• Broad-spectrum topical antibiotics, including trimethoprim-polymyxin B (q.i.d.) or a topical fluoroquinolone (q.i.d.), are typically used empirically to treat mild cases of bacterial conjunctivitis for five to seven days. When it comes to fourth-generation fluoroquinolones (gatifloxacin or moxifloxacin), the least amount of broad-spectrum antibiotic resistance is seen.
Treatment for H. influenzae should involve oral amoxicillin/clavulanate (20–40 mg/kg/day in three divided doses).
dosages) due to sporadic extraocular involvement (e.g., meningitis, pneumonia, otitis media).
• Systemic ceftriaxone treatment is necessary for gonococcal conjunctivitis, whether or not keratitis is present. One dosage of ceftriaxone (1 g i.m.) is adequate if there is no corneal involvement; if there is corneal involvement, an intravenous dose of ceftriaxone (1 g i.v. q.d.–b.i.d.) is required in addition to a topical fourth-generation fluoroquinolone (gatifloxacin or moxifloxacin every hour, 24/7). The clinical response determines how long a treatment will last. It is also advised to treat any potential chlamydial co-infection with a single oral azithromycin dosage (1 g p.o.).
• One dosage of oral azithromycin (1 g p.o.) combined with topical erythromycin or tetracycline ophthalmic ointment used b.i.d. or t.i.d. for two to three weeks is used to treat adult inclusion conjunctivitis.
• A single dosage of azithromycin (20 mg/kg p.o.) and topical erythromycin, tetracycline, or sulfacetamide ointment (b.i.d.–q.i.d.) are used to cure trachoma for three to four weeks.
• In immune-competent hosts, cat scratch illness typically heals on its own without treatment. One option is oral azithromycin (500 mg p.o. q.i.d. for the first day and then 250 mg p.o. q.d. for the next four days). The dosage of azithromycin for children is modified to be 10 mg/kg p.o. q.i.d. on the first day and 5 mg/kg p.o. q.d. for the next four days. Topical antibiotics like eyedrops of gentamicin (q.i.d.) or
It is also possible to administer bacitracin/polymyxin B ointment (q.i.d.).
• Systemic antimicrobials should be used to treat ophthalmia neonatorum in order to prevent systemic involvement, as concurrent pharyngeal infections are frequently present:
Systemic ceftriaxone (25–50 mg/kg i.v. or i.m. to a maximum of 125 mg) combined with regular saline irrigations to eliminate the discharge is recommended for N. gonorrhoeae. To treat neonatal gonococcal ophthalmia, ceftriaxone is administered intramuscularly only once.
- C. trachomatis: topical erythromycin ointment and oral erythromycin (50 mg/kg/day p.o. in 4 split doses) for 2 weeks (q.i.d.).
Intravenous acyclovir (45–60 mg/kg/day, divided in 3 doses) should be administered to full-term infants for 2 weeks if the disease only affects the eyes, skin, and mouth, and for 3 weeks if it affects the central nervous system. It is also recommended to start topical treatment with vidarabine ointment (3% five times a day) or trifluridine eyedrops (1% nine times a day).
Line Two
• Oral erythromycin (500 mg p.o. q.i.d.) or doxycycline (100 mg p.o. b.i.d.) can also be used to treat adult inclusion conjunctivitis for seven days.
• Doxycycline is an other treatment option for trachoma.
(100 mg p.o. b.i.d.) or 500 mg p.o. q.i.d.) of erythromycin for two weeks.
• If a patient has gonococcal conjunctivitis and is allergic to penicillins, try giving them 500 mg of ciprofloxacin orally for five days. Emerging opposition, however, is a serious worry.
• Adults with cat scratch illness may get 100 mg of doxycycline p.o. b.i.d.
ADDITIONAL MEDICATION
Overall Actions
It is recommended to often irrigate the purulent discharge with saline when gonococcal conjunctivitis is present.
Referral Issues
An ID consultation should be obtained in cases of adult inclusion conjunctivitis or gonococcal infection.
OTHER PROCEDURES AND SURGERY
A conjunctival biopsy may occasionally be necessary to make a diagnosis, such as OCP.
Considering the patient
Requirements for Admission
Except for patients requiring intravenous antibiotics and ophthalmia neonatorum, conjunctivitis is treated as an outpatient condition.
PERMANENT CARE DIET
There are no dietary restrictions.
PATIENT EDUCATION Teach patients how to maintain good hygiene.
PROGNOSIS
Rarely can infectious conjunctivitis persist for longer than three weeks, with the exception of chlamydial conjunctivitis.
COMPLICATIONS
• Chronic conjunctival inflammation in trachoma causes the eyelids to deform, turning inward (trichiasis and entropion), and causes scarring. Compromise of the corneal epithelium may result in opacification and scarring.
• Subepithelial infiltrates (inflammatory superficial corneal opacities) may form in viral EKC.
nature), which would necessitate long-term topical steroid treatment.
• Infants with ophthalmia neonatorum are susceptible to systemic infections, including rhinitis, stomatitis, arthritis, meningitis, and sepsis (N. gonorrhoeae), otitis and pneumonitis (C. trachomatis), and encephalitis (HSV), as a result of exposure to pathogens during transit through the birth canal.
