Intranasal Corticosteroids and Central Serous Chorioretinopathy: A Report and Review of the Literature.

A 43-year-old male with a history of allergic rhinitis on chronic intranasal corticosteroids presented with complaints of a "black band" in his right eye visual field. On examination, he had subretinal fluid and lab tests and imaging studies including optical coherence tomography (OCT) and fluorescein angiography (FA) did not show any evidence of inflammatory, degenerative, or malignant process. He was diagnosed with central serous chorioretinopathy (CSCR). Symptoms improved and the subretinal fluid resolved after the discontinuation of intranasal corticosteroid medication. Intranasal corticosteroids are rarely associated with CSCR. Patients and providers should be aware of the potential risk of vision loss caused by intranasal corticosteroids.
