Acute angle-closure glaucoma associated with intranasal phenylephrine to treat epistaxis.

Comment. Subtenon corticosteroid injections are commonly used in the treatment of macular edema or posterior segment intraocular inflammation. Complications include inadvertent intravascular injection, globe perforation, cataract formation, ocular hypertension, blepharoptosis, orbital fat atrophy, strabismus, or allergic reactions. To our knowledge, this is the first report of an abscess resulting from such an injection. The lack of inflammation was atypical for an infection and was likely related to the local immunosuppressive effects of triamcinolone.
