Treatment of Conjunctivitis with Periocular Swelling
For conjunctivitis with swelling around the eye, determine the etiology first through clinical features, then treat accordingly: viral cases require supportive care only, bacterial cases need topical antibiotics for moderate-to-severe presentations, and severe cases with marked lid swelling may warrant short-term topical corticosteroids under close monitoring. 1, 2
Immediate Assessment and Red Flags
Refer urgently to ophthalmology if any of the following are present:
- Visual loss or decreased vision 1, 2
- Moderate or severe pain 1, 2
- Severe purulent discharge 1, 2
- Corneal involvement 1, 2
- History of herpes simplex virus eye disease 1, 2
- Immunocompromised state 1, 2
Severe eyelid swelling with chemosis can mimic orbital cellulitis in viral conjunctivitis, particularly adenoviral infections, but this is typically self-limited over 5-14 days. 2
Determine Etiology Based on Clinical Features
Viral Conjunctivitis (Most Common Overall)
Key distinguishing features:
- Watery discharge 2, 3
- Follicular reaction on inferior tarsal conjunctiva 2
- Preauricular lymphadenopathy 2
- Often starts unilateral, becomes sequentially bilateral 2
- Chemosis and marked eyelid swelling can occur in severe cases 2
- Concurrent upper respiratory infection common 2
Bacterial Conjunctivitis
Key distinguishing features:
- Mucopurulent discharge with matted eyelids on waking 2, 4, 3
- Papillary (not follicular) reaction 2
- Lack of itching 4
- Preauricular lymphadenopathy less common unless hypervirulent organisms 2
Gonococcal Conjunctivitis (Medical Emergency)
Key distinguishing features:
- Marked eyelid edema 2
- Severe, bilateral purulent discharge 1, 2
- Bulbar conjunctival injection 2
- Risk of corneal perforation 2
- Consider in sexually active adults or neonates 3-5 days postpartum 5
Treatment by Etiology
Viral Conjunctivitis Treatment
Standard supportive care:
- Preservative-free artificial tears applied frequently 6
- Cold compresses for inflammation and symptomatic relief 6
- Oral analgesics (acetaminophen or NSAIDs) for pain 6
- Avoid antibiotics entirely—they provide no benefit and may cause toxicity 2
For severe cases with marked chemosis and lid swelling:
- Consider short course of topical corticosteroids 1, 6
- Use agents with poor ocular penetration: fluorometholone, rimexolone, or loteprednol 1, 6
- Monitor intraocular pressure and perform pupillary dilation periodically 1, 6
- Taper once inflammation is controlled 1
- Caution: Corticosteroids may prolong viral shedding and worsen HSV infections 2
Infection control measures:
- Strict hand hygiene with soap and water 2, 6
- Avoid sharing towels and pillows 2, 6
- Minimize contact with others for 10-14 days from symptom onset 2, 6
Bacterial Conjunctivitis Treatment
For moderate-to-severe presentations:
- 5-7 day course of broad-spectrum topical antibiotic 2
- No specific agent is superior—choose based on convenience or cost 2
- Options include erythromycin ophthalmic ointment 7 or bacitracin 8
- Apply ointment 1-3 times daily directly into conjunctival sac 8
Mild cases:
- Usually self-limited and may resolve without treatment 2, 4
- Topical antibiotics may decrease duration and allow earlier return to work/school 4
Gonococcal Conjunctivitis Treatment (Requires Hospitalization)
- Systemic therapy is mandatory in addition to topical treatment 1, 2
- Hospitalization necessary for parenteral therapy 1
- Daily follow-up until resolution 1
- Treat sexual contacts and screen for concomitant disease 1
- Consider sexual abuse in children 1
Chlamydial Conjunctivitis Treatment
- Systemic therapy required—topical therapy alone is inadequate 1, 2
- Treat sexual contacts simultaneously 1, 2
- Re-evaluate after treatment (failure rate up to 19%) 1
- Consider sexual abuse in children 1
Follow-Up Recommendations
For severe cases with corneal involvement or membranous conjunctivitis:
- Re-evaluate within 1 week 1, 6
- Include interval history, visual acuity measurement, and slit-lamp biomicroscopy 1, 6
For patients not on corticosteroids:
For patients on topical corticosteroids:
Critical Pitfalls to Avoid
- Never use antibiotics indiscriminately for viral conjunctivitis—they cause unnecessary toxicity 1, 2
- Never use topical corticosteroids without close ophthalmology follow-up—risk of elevated intraocular pressure, cataract formation, and worsening HSV infections 2
- Never miss gonococcal conjunctivitis—it can cause corneal perforation and requires immediate systemic treatment 1, 2
- Never allow contact lens wear during any infectious conjunctivitis 2
- Chronic or recalcitrant conjunctivitis may indicate underlying malignancy (sebaceous or squamous cell carcinoma) and requires further evaluation 2
