Phenylephrine eye drops can cause acute allergic blepharoconjunctivitis, presenting with discharge and inflammation. This reaction, observed even at low concentrations, resolves within 72 hours.

Area of Science:

  • Ophthalmology
  • Allergy and Immunology

Background:

  • Phenylephrine is a common ingredient in over-the-counter eye drops.
  • Allergic reactions to ophthalmic medications can cause significant ocular discomfort and inflammation.

Purpose of the Study:

  • To report a case of acute allergic blepharoconjunctivitis caused by phenylephrine eye drops.
  • To characterize the clinical presentation and histological findings of this adverse reaction.

Main Methods:

  • Clinical observation of patient symptoms and reaction timeline.
  • Analysis of conjunctival biopsy findings.

Main Results:

  • A case of acute allergic blepharoconjunctivitis with mucopurulent discharge was observed.
  • The reaction occurred 3-4 hours after phenylephrine application, lasting 12 hours and resolving within 72 hours.

  • Histopathology showed infiltration by lymphocytes, plasma cells, and eosinophils.

    • Conclusions:

    • Phenylephrine eye drops can induce acute allergic blepharoconjunctivitis, even at low concentrations (0.1%).
    • The reaction involves a mixed inflammatory infiltrate in the conjunctiva.
    • Awareness of this potential adverse effect is crucial for clinicians prescribing phenylephrine eye drops.
