Viral Conjunctivitis Management

Introduction to Conjunctivitis

Conjunctivitis can be classified into three main categories: viral, bacterial, and allergic, with distinct presentations and symptoms, such as watery discharge, purulent or mucopurulent discharge, and intense itching, respectively 1
The character of discharge (watery, mucoid, or purulent) and associated symptoms (itching, pain, and photophobia) are important considerations in the diagnosis of conjunctivitis 2

The American Academy of Ophthalmology recommends supportive care, including artificial tears and cold compresses, as viral conjunctivitis is typically self-limiting and does not respond to antibiotics, and strict hygiene measures to prevent spread 1
Vaccination is strongly recommended for patients ≥50 years or immunocompromised patients ≥19 years to prevent viral conjunctivitis 1
Frequent hand washing, use of separate towels and pillows, and avoidance of close contact with others during the contagious period (10-14 days from onset) are recommended to prevent the spread of viral conjunctivitis 1
Surfaces should be properly disinfected with a dilute bleach solution (1:10) to prevent the spread of viral conjunctivitis 1
Proper hygiene measures, such as frequent handwashing by caregivers, separate towels and washcloths, avoiding sharing pillowcases, and proper disinfection of toys and surfaces, are essential to prevent the spread of conjunctivitis 1, 3

Topical broad-spectrum antibiotics for 5-7 days are recommended as first-line treatment for bacterial conjunctivitis, with options including polymyxin B-trimethoprim ophthalmic solution, gentamicin ophthalmic solution, and moxifloxacin 0.5% ophthalmic solution 1, 4
Moxifloxacin 0.5% ophthalmic solution is effective against common pathogens, including Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, and Haemophilus influenzae 4
Delayed antibiotic prescribing may be considered for mild cases of bacterial conjunctivitis, as it has been found to have similar symptom control as immediate prescribing 4, 1
Warm compresses are recommended over cold compresses for bacterial conjunctivitis, as they help soften discharge, loosen crusts, and express meibomian gland secretions that may harbor bacteria, according to the American Academy of Ophthalmology 5

Erythromycin demonstrates high clinical (96%) and microbiological cure rates (97%) for chlamydial conjunctivitis in neonates 4
Gonococcal conjunctivitis requires both systemic and topical therapy, with systemic treatment options including ceftriaxone, as recommended by the CDC 1
Chlamydial conjunctivitis requires systemic therapy, with options including azithromycin, doxycycline, or levofloxacin, as recommended by the CDC 1

The following table outlines suggested infections based on time of onset in neonates:

Time of Onset	Suggested Infection
1-7 days after birth	Gonococcal infection
5-19 days	Chlamydial infection
First week	Common bacterial infection (Staphylococcus aureus, Enterococcus, Klebsiella, E. coli)

Tonometers should be disinfected with a dilute bleach soak (1:10) in healthcare settings to prevent the spread of viral conjunctivitis 1
A dilute bleach solution (1:10) is recommended for disinfecting surfaces to prevent the spread of infection, according to the American Academy of Ophthalmology 2

Patients experiencing visual loss, moderate or severe pain, severe purulent discharge, corneal involvement, conjunctival scarring, or lack of response to therapy after 3-4 days should seek ophthalmology referral 1
Refer patients with no response to therapy after 3-4 days, moderate to severe pain, decreased vision, corneal involvement, recurrent episodes, history of herpes simplex virus eye disease, or immunocompromised patients, as these cases may require more aggressive treatment or specialist care 3, 1
If herpes simplex virus is suspected, characterized by a vesicular rash or dendritic lesions, referral to an ophthalmologist is recommended by the American Academy of Ophthalmology 1
For severe adenoviral conjunctivitis, ophthalmology referral may be needed, as suggested by the American Academy of Ophthalmology 1
