title: Delayed hypersensitivity to retrobulbar injections of methylprednisolone acetate.
abstract: A patient with chronic cyclitis developed hyperemia of the episcleral and bulbar conjunctival vessels after retrobulbar injections of methylprednisolone acetate suspension. Intradermal testing revealed the responsible allergen to be methylprednisolone acetate; hypersensitivity could not be demonstrated by patch testing, despite use of increased concentrations.
