Treatment of Seasonal or Perennial Allergic Conjunctivitis

Clinical Scenario

This protocol addresses patients with a confirmed diagnosis of seasonal or perennial allergic conjunctivitis — a common ocular allergic condition that ranges from intermittent mild episodes to persistent, recurrent disease.

Management Approach

A foundation of simple, broadly applicable measures applies across virtually all presentations: physical barriers to airborne allergens, cold compresses, refrigerated artificial tears, strict avoidance of the responsible allergen, and environmental modifications including changes to bedding and personal hygiene routines.

Beyond these measures, topical pharmacotherapy — with options differing by disease severity and recurrence pattern — forms the core of the regimen. The protocol distinguishes between approaches for mild disease and those for frequently recurrent or persistent cases.

The full stepwise regimen — including specific agent categories, selection criteria by severity, and options when disease persists — is available in the complete structured protocol.

Table 2 lists topical medications that can be used for seasonal allergic conjunctivitis.
Simple measures that are applicable to almost all situations include wearing sunglasses as a barrier to airborne allergens, cold compresses, refrigerated artificial tears, avoiding eye rubbing, and avoiding allergen.
Hypoallergenic bedding, eyelid cleansers to remove allergens, frequent clothes washing, and bathing/showering before bedtime may also be helpful.
Mild allergic conjunctivitis can be treated with an over-the-counter topical antihistamine/vasoconstrictor agent or with the more effective second-generation topical histamine H1-receptor antagonists.
If the condition is frequently recurrent or persistent, mast-cell stabilizers can be used.
Many new medications combine antihistamine activity with mast-cell stabilizing properties and can be used for either acute or chronic disease.
