Transient Blindness Following Intranasal Steroid Injection: A Case Report / 대한이비인후과학회지

ABSTRACT

Intranasal corticosteroid injection has been used for the control of allergic rhinitis or polypoid inflammation of the nasal cavity. Transient or permanent visual loss after therapeutic intranasal injection of corticosteroid is an extremely rare but well-known disease. In this report, we present a 54-year-old male patient with chronic sinusitis with nasal polyposis who had right visual loss after bilateral intranasal triamcinolone injection. Clinical examination and fluorescent angiography revealed vascular occlusions, which involved multiple small branches of right retinal circulations. Full recovery of vision occurred 3 months after the onset of the symptom. Extreme care should be exercised to avoid visiual complication when intranasal corticosteroid injection is performed.
