Rationale: To report a case of bilateral transient corneal edema presumably associated with adenovirus-vectored coronavirus disease 2019 (COVID-19) vaccination that resolved with eye drops treatment.
Patient concerns: A 55-year-old Asian woman presented with sudden onset of bilateral visual disturbance developed 6 days after immunization with an adenovirus-vectored COVID-19 vaccine (AstraZeneca, London, United Kingdom). She underwent uneventful cataract surgery in right and left eyes 2 months ago and maintained good visual acuity bilaterally. Slit-lamp examination showed bilateral mild corneal edema that was confirmed with anterior segment optical coherent tomography. Anterior chamber and vitreous were clear bilaterally. Both fundi were normal.
Diagnoses: The patient was diagnosed with corneal edema following adenovirus-vectored COVID-19 vaccination.
Interventions: She was prescribed with prednisolone acetate 1% eye drops bilaterally.
Outcomes: Treatment with topical steroid for 2 weeks resulted in resolution of the corneal edema and improvement of the visual acuity bilaterally.
Lessons: This case suggests that transient corneal edema can develop following adenovirus-vectored COVID-19 vaccination. Prompt ophthalmologic evaluation and treatment may improve the corneal edema.
