Unilateral Episcleritis Following COVID-19 Booster Vaccination of a Crohn’s Disease Patient: A Case Report and Review of the Literature

Abstract

Purpose: The Coronavirus Disease 2019 (COVID-19) pandemic spurred vaccine development and resulted in the development of the novel mRNA COVID-19 vaccine and with it, a growing public concern of vaccine side effects. There are reports of ocular inflammatory processes such as episcleritis being possible side effects of COVID-19 vaccination. Here we reported the first case of unilateral episcleritis in a Crohn’s disease patient following her third mRNA COVID-19 vaccination booster shot. Patient and Methods: A 27-year-old female presented with a 1-day history of right eye redness, itching, and burning. Patient reported developing these symptoms within 3–4 hours after vaccination. Her past medical history was relevant for Crohn’s disease. Ophthalmic examination revealed right 2+ conjunctival injection that blanched with phenylephrine drops. Otherwise, her ophthalmic exam was unremarkable. The patient was started on artificial tears and ibuprofen 200 mg three times daily for one week. After one week all symptoms resolved, and ophthalmic examination was back to baseline. Conclusion: This is the first case in the literature of ophthalmic side effects in a Crohn’s disease patient after the third mRNA COVID-19 booster. Patients with Crohn’s disease may respond differently to booster vaccination. This case report may help healthcare providers when counselling Crohn’s disease patients about future COVID-19 mRNA vaccine side effects.
