Thyroid eye disease reactivation associated with COVID-19 vaccination

Abstract

To describe the presentation of both new-onset and reactivation of thyroid eye disease (TED) following COVID-19 vaccination. Single-institution retrospective case series of patients presenting with symptoms and signs of new or reactivated TED coinciding with recent COVID-19 vaccination. Data collected included patient age, gender, presenting symptoms, ocular history, clinical signs, and interval duration between vaccination and onset of ocular symptoms. Three female patients were identified. All patients were over 18 years of age (range 45–66 years). Patients received either the Moderna or Pfizer COVID-19 vaccine and presented with symptoms of TED within 24 h to 21 days of receiving their first or second dose. None of the patients had previous infections with severe acute respiratory syndrome coronavirus 2. Two patients had a history of inactive TED with stable thyroid function tests: One of these patients had stable disease for at least 15 years and the other had stable disease for 5 years. The third patient had no previous history of thyroid dysfunction or TED and presented with low levels of thyroid-stimulating hormone. All three cases presented with proptosis. In two of three cases, periorbital edema, eyelid retraction, and diplopia were present. None were current smokers. One had prior facial hyaluronic acid filler injections. Symptoms in all cases were improving at 4 to 8 months. While the possibility of unrelated TED flaring concurrently with COVID-19 vaccination exists, questions remain on the effects of the COVID-19 vaccine in patients with autoimmune ophthalmic diseases. Physicians should be aware of this potential association and counsel patients appropriately.
