ALLERGIC REACTION TO TROPICAMIDE EYE DROPS- A CASE REPORT

*Tharini Senthamizh and Subashini Kaliaperumal

ABSTRACT

Tropicamide is a commonly used eye drop in ophthalmology clinic to enable detailed examination of eye structures. Allergy to this drug is not so common and is often overlooked. Although most allergies reported were due to preservative component of the eye drops, tropicamide per se can also cause serious allergic reaction. Diagnosis of such allergic reactions can be done by clinical examination and skin patch testing. When we are so sure of the allergy clinically but skin test turns out to be negative for that drug, conjunctival challenge test can be used to confirm the diagnosis. We report a case of tropicamide allergy which showed negative skin testing but positive conjunctival challenge test, thus proving the usefulness of the test in clinical setup.
