Optic disc drusen presenting as papilledema: a case report

Optic disc drusens, which are congenital anomalies of optic nerve head, are depositions of mucopolysaccharides and pro-teinaceous material within the optic nerve head. They are usually bilateral and diagnosed incidentally during routine fundus examination where they may be mistaken for papilledema. We report a case of 63 year old female referred to the neuro-ophthalmology department with the clinical suspicion of disc edema. Simple noninvasive investigations like ultrasound B-scan, fundus autofluorescene along with the newer test like spectral domain optical coherence tomography helped us to diagnose it as a case of pseudopapilledema, as optic disc drusen. Thus, a high index of suspicion along with the ancillary tests is helpful in differentiating optic disc drusen from true papilledema.
