- No foreign body. Punctate calcification at the junction of the optic nerve and globe bilaterally, compatible with optic disc drusen.
Diagnosis
Optic Disc Drusen
Discussion
-
Optic disc drusen are calcified hyaline material.
-
Most commonly occur at the optic disc (i.e. the point of entry of the optic nerve at the retina), but can occur anywhere along the retina.
-
Typically punctate in size.
-
Usually easy to differentiate from an orbital mass or foreign body given characteristic location at the optic disc and absence of an associated mass.
-
Typically occur in older patients with age-related macular degeneration, but can occur in younger patients.
-
They can be a mimic for papilledema on fundoscopic exam ("pseudopapilledema").
