Treatment of Conjunctivitis

Diagnosis and Classification

• The American Academy of Ophthalmology recommends that patients with gonococcal conjunctivitis require systemic antibiotics and daily follow-up until resolution 1
• The American Academy of Ophthalmology suggests that chlamydial conjunctivitis necessitates systemic antibiotic therapy, as more than 50% of infants with this condition may have infection at other sites 2

Treatment by Type

Bacterial Conjunctivitis

• Patients with bacterial conjunctivitis should be advised to return for evaluation if no improvement is seen after 3-4 days of treatment, as recommended by the American Academy of Ophthalmology 2
• The American Academy of Ophthalmology recommends that sexual contacts of patients with sexually transmitted conjunctivitis should be treated concurrently 3
• In low-to-middle income countries with limited antibiotic access, the American Academy of Ophthalmology suggests that povidone-iodine 1.25% ophthalmic solution can be used for chlamydial conjunctivitis 2

Allergic Conjunctivitis

• The American Academy of Ophthalmology recommends simple measures such as wearing sunglasses as barriers to airborne allergens, cold compresses, and refrigerated artificial tears for allergic conjunctivitis 4
• The American Academy of Ophthalmology suggests that topical antihistamines with mast cell-stabilizing properties are the treatment of choice for allergic conjunctivitis 4
• For persistent or recurrent cases of allergic conjunctivitis, the American Academy of Ophthalmology recommends that mast cell stabilizers can be used 4
• In severe cases of allergic conjunctivitis, the American Academy of Ophthalmology suggests that a brief course (1-2 weeks) of topical corticosteroids with a low side-effect profile may be added 4

Special Considerations

• The American Academy of Ophthalmology recommends that hospitalization may be necessary for severe gonococcal conjunctivitis and is mandatory for neonatal conjunctivitis 3

Referral to Ophthalmologist

• The American Academy of Ophthalmology recommends immediate referral for patients with visual loss, moderate or severe pain, severe purulent discharge, corneal involvement, conjunctival scarring, lack of response to therapy, recurrent episodes, history of HSV eye disease, or history of immunocompromise 1, 3

Common Pitfalls

• The American Academy of Ophthalmology warns that indiscriminate use of topical antibiotics or corticosteroids should be avoided, as they can induce toxicity and potentially prolong adenoviral infections and worsen HSV infections 4

Tratamiento de la Conjuntivitis

Tipos de Conjuntivitis y Tratamientos Específicos

• El tratamiento de la conjuntivitis debe adaptarse específicamente a la causa subyacente, siendo los antibióticos tópicos indicados para la conjuntivitis bacteriana, los antihistamínicos para la alérgica, y el cuidado de soporte para la viral, según la American Academy of Ophthalmology 5, 6
• La conjuntivitis bacteriana no requiere antibióticos en casos leves, ya que puede resolverse espontáneamente sin tratamiento específico, según la American Academy of Ophthalmology 6
• En casos moderados a severos de conjuntivitis bacteriana, la elección del antibiótico debe guiarse por resultados de cultivos y pruebas de laboratorio, según la American Academy of Ophthalmology 7
• La conjuntivitis gonocócica requiere terapia antibiótica sistémica, según la American Academy of Ophthalmology 7
• La conjuntivitis por Clamidia requiere tratamiento sistémico con antibióticos, según la American Academy of Ophthalmology 7
• En casos más severos de conjuntivitis alérgica, pueden requerirse corticosteroides tópicos por períodos breves, según la American Academy of Ophthalmology 8
• Es importante identificar y evitar los alérgenos desencadenantes en la conjuntivitis alérgica, según la American Academy of Ophthalmology 5

Medidas Preventivas

• No compartir toallas, almohadas o cosméticos para prevenir la transmisión de la conjuntivitis, según la American Academy of Ophthalmology 5
• En usuarios de lentes de contacto con conjuntivitis, suspender su uso hasta la resolución completa, según la American Academy of Ophthalmology 8

Algoritmo de Tratamiento

• Identificar el tipo de conjuntivitis (viral, bacteriana o alérgica) basado en síntomas y signos, según la American Academy of Ophthalmology 5
• Para conjuntivitis bacteriana moderada-severa, antibióticos tópicos guiados por cultivos, según la American Academy of Ophthalmology 7
• Reevaluar si no hay mejoría en 3-4 días, según la American Academy of Ophthalmology 7

Conjunctivitis Evaluation and Management

Critical Red Flags to Rule Out

• The absence of visual loss, severe pain, corneal involvement, and purulent discharge indicates uncomplicated disease that can be managed in primary care without urgent ophthalmology referral, as recommended by the American Academy of Ophthalmology 9, 10
• No visual loss is present, suggesting no corneal involvement, uveitis, or other serious pathology requiring ophthalmology referral, according to the American Academy of Ophthalmology 9
• The absence of moderate-to-severe pain indicates no potential keratitis, uveitis, acute angle-closure glaucoma, or corneal ulceration, as stated by the American Academy of Ophthalmology 9
• No photophobia is present, suggesting no corneal or intraocular inflammation beyond superficial conjunctivitis, as reported by the American Academy of Ophthalmology 11
• No corneal involvement is present, confirming disease limited to conjunctiva, as recommended by the American Academy of Ophthalmology 9
• No conjunctival scarring is present, suggesting no chronic disease, cicatricial conjunctivitis, or previous severe inflammation requiring specialist management, according to the American Academy of Ophthalmology 10
• No membrane or pseudomembrane formation is present, indicating no severe adenoviral infection or other serious etiologies, as stated by the American Academy of Ophthalmology 11
• No history of HSV eye disease is present, which would increase the risk of recurrence and require specialist management, as recommended by the American Academy of Ophthalmology 9
• No immunocompromised state is present, which would increase the risk of atypical or severe infections requiring closer monitoring, according to the American Academy of Ophthalmology 10
• Immediate ophthalmology referral is indicated if any red flag is present, as recommended by the American Academy of Ophthalmology 9, 10
• Failing to assess for child abuse is a critical pitfall to avoid, as sexually transmitted conjunctivitis in children mandates consideration of abuse and appropriate reporting, according to the American Academy of Ophthalmology 10

Conjunctivitis Diagnosis and Treatment

Immediate Red Flags Requiring Ophthalmology Referral

• Moderate or severe pain suggests keratitis, uveitis, or acute angle-closure glaucoma, and requires immediate ophthalmology referral in patients with conjunctivitis 12
• Corneal involvement, as indicated by fluorescein staining showing epithelial defects, is a red flag for ophthalmology referral in conjunctivitis patients 12
• Conjunctival scarring is a sign of severe conjunctivitis and requires ophthalmology referral 12
• History of HSV eye disease is a risk factor for complications in conjunctivitis patients and requires ophthalmology referral 12
• Immunocompromised state increases the risk of complications in conjunctivitis patients and requires ophthalmology referral 12
• Recurrent episodes of conjunctivitis may indicate an underlying condition and require ophthalmology referral 12

Viral Conjunctivitis

• Preauricular lymphadenopathy is a common finding in viral conjunctivitis, according to the American Academy of Ophthalmology 13
• May have concurrent upper respiratory infection, and the American Academy of Ophthalmology recommends supportive care for viral conjunctivitis 13
• Artificial tears and cold compresses can provide symptomatic relief for viral conjunctivitis patients, as recommended by the American Academy of Ophthalmology 13
• Topical antihistamines can be used for symptomatic relief in viral conjunctivitis, but the American Academy of Ophthalmology recommends avoiding topical corticosteroids 13

Bacterial Conjunctivitis

• Gonococcal conjunctivitis requires immediate systemic antibiotics and topical therapy, and hospitalization may be necessary, according to the American Academy of Ophthalmology 12
• Chlamydial conjunctivitis requires systemic antibiotic therapy, and the American Academy of Ophthalmology recommends treating sexual contacts concurrently 12
• Povidone-iodine 1.25% ophthalmic solution can be used to treat chlamydial conjunctivitis in low-to-middle income countries with limited antibiotic access, as recommended by the American Academy of Ophthalmology 12

Allergic Conjunctivitis

• Topical antihistamines with mast cell-stabilizing activity are first-line treatment for allergic conjunctivitis, according to the American Academy of Ophthalmology 13
• Environmental modifications, such as wearing sunglasses and avoiding eye rubbing, can help alleviate symptoms of allergic conjunctivitis, as recommended by the American Academy of Ophthalmology 13
• Mast cell stabilizers can be used to treat persistent or recurrent allergic conjunctivitis, according to the American Academy of Ophthalmology 13

Infection Control Measures

• Hand washing is the single most important measure to prevent transmission of infectious conjunctivitis, according to the American Academy of Ophthalmology 12
• Disinfecting surfaces with EPA-registered hospital disinfectant or 1:10 dilution of household bleach can help prevent transmission of infectious conjunctivitis, as recommended by the American Academy of Ophthalmology 13
