Abstrakt: Background Anti-vascular endothelial growth factor ( VEGF) medication, injected intravitreally, is currently the standard of care in patients with different retinal pathologies. Since its introduction in 2006, an increasing number of patients have undergone this procedure in Ghent University Hospital. Strikingly, more patients were diagnosed with contact dermatitis caused by ophthalmic products used during intravitreal injection procedure. Objectives To identify which of the substances used during intravitreal injection is most likely to cause contact dermatitis. Patients/materials/methods Sixteen patients who developed a burning and stinging sensation and swelling of the eyelids after intravitreal injection were tested. All patients were patch tested with the Belgian baseline series, as well as a cosmetic, a pharmaceutical and an ophthalmic series, including the different eye drops used during the intravitreal injection procedure. Results Fourteen of 16 patients reacted to at least one of the substances used during the injection procedure. Nine patients reacted to phenylephrine (56%), 5 to iso-Betadine® ophthalmic solution (31%), and 3 patients to sodium metabisulfite (16%). Conclusions The most common causal allergen was phenylephrine, being positive in 56% of patients. Patients most likely become sensitized because of the high frequency of usage of phenylephrine during repeated intravitreal injections and follow-up consultations. [ABSTRACT FROM AUTHOR]
