Documentation of Allergic Conjunctivitis
Document allergic conjunctivitis by recording specific history elements (allergy/asthma/eczema, bilateral itching, watery discharge, exacerbating factors), visual acuity, external examination findings (papillary reaction on tarsal conjunctiva, conjunctival injection pattern, discharge character), corneal clarity, pupillary reactions, extraocular movements, and your treatment plan with follow-up timing. 1
Essential History Elements to Document
Document the following specific historical features that distinguish allergic from other forms of conjunctivitis 1:
Symptom Characteristics:
- Itching (hallmark symptom of allergic conjunctivitis)
- Tearing and watery discharge
- Duration and time course of symptoms
- Bilateral vs. unilateral presentation (allergic is typically bilateral)
- Exacerbating factors (seasonal patterns, environmental triggers)
Relevant Medical History:
- Personal history of allergy, asthma, or eczema
- Previous episodes of conjunctivitis
- Current topical and systemic medications
- Smoking exposure and environmental pollutants
- Contact lens wear (type, hygiene, regimen)
Associated Systemic Conditions:
- Atopic dermatitis
- Allergic rhinitis
- Other atopic conditions 2
Physical Examination Documentation
Visual Function
- Visual acuity measurement for each eye 1
- Document any photophobia or pain (suggests severe forms or corneal involvement) 2
External Examination
Regional Assessment:
- Preauricular lymphadenopathy (typically absent in simple allergic conjunctivitis) 1
- Skin signs: rosacea, eczema, seborrhea 1
Eyelid Findings:
- Swelling, discoloration, malposition
- Laxity, lateral flare, lash loss 1
Conjunctival Examination
Critical Findings to Document:
- Laterality (allergic conjunctivitis is typically bilateral) 1
- Type of reaction: Papillary vs. follicular (allergic shows papillary hypertrophy, especially on upper tarsal conjunctiva) 2, 3
- Distribution pattern: diffuse vs. localized 1
- Conjunctival appearance: "milky" appearance is characteristic 3
- Degree of conjunctival injection/hyperemia 1
- Chemosis (conjunctival swelling)
Discharge Characteristics:
- Stringy or ropy mucoid discharge is typical of allergic conjunctivitis 3
- Watery discharge common 1, 4
- Document color and consistency
Corneal Assessment
- Corneal clarity (rule out keratitis or corneal involvement) 1
- Punctate epithelial keratitis (suggests more severe forms)
- Corneal pannus (seen in chronic severe cases)
Additional Ocular Findings
- Pupillary reactions (should be normal in simple allergic conjunctivitis) 1
- Extraocular movements (should be full and unrestricted) 1
Treatment and Follow-up Documentation
Document Your Treatment Plan:
- Specific medications prescribed (topical antihistamines, mast cell stabilizers, dual-acting agents) 5, 6
- Non-pharmacological interventions: artificial tears, cold compresses, allergen avoidance 6
- Patient education provided regarding trigger avoidance
Follow-up Plan:
- Timing of next visit
- Criteria for earlier return (worsening pain, vision changes, lack of improvement)
- Referral to ophthalmology if severe forms suspected (vernal or atopic keratoconjunctivitis with corneal involvement) 7
Common Pitfalls to Avoid
Do not miss these red flags that suggest alternative diagnoses:
- Severe pain or photophobia (suggests corneal involvement or other pathology)
- Decreased vision (requires urgent evaluation)
- Unilateral presentation (consider infectious or other causes)
- Purulent discharge (suggests bacterial conjunctivitis) 4
- Follicular reaction (suggests viral or chlamydial conjunctivitis, not allergic) 1
Key Distinguishing Feature: The presence of upper tarsal papillary reaction with itching and stringy discharge in a bilateral pattern strongly supports allergic conjunctivitis over infectious causes 2, 3.
