Optic Disc Drusen with Optic Nerve Head Edema and Normal ICP Treated with Acetazolamide

Optic disc drusen (ODD) is a well known cause of optic nerve elevation and pseudopapilledema. Although acetazolamide has been shown to be an effective therapy for disc edema associated with increased intracranial pressure (ICP), prior studies have not reported the use of acetazolamide to address concurrent optic disc head elevation (ODHE) in ODD in the setting of normal ICP. We present a series of three patients of such condition treated successfully with acetazolamide.
