[Optic disk drusen: what are the advantages of the new imaging techniques?].

This study reports four clinical cases of papillary drusen associated with OHT. The authors show the advantages of HRT, OCT2, and GDx for exploring the optic nerve and/or the retinal nerve fiber layer (RNFL). The repercussions of drusen on the optic nerve head may precede visual field failure. Better knowledge of the interpretation of these new imaging techniques may help define the respective roles of drusen and OHT, in case of visual field attack, and treatment modalities. These new procedures may help us to monitor drusen and their progression potential.
