title: [Deep and hidden drusen of the optic nerve as cause of pseudopapilledema (author's transl)].
abstract: We examined 160 patients with pseudopapilledema caused by deep and hidden drusen. The advantages of ophthalmochromoscopy versus fluorescein angiography in diagnosing deep drusen are demonstrated. The role of fluorescein examination in differentiating pseudopapilledema from genuine papilledema is pointed out. After many years of observation of patients suffering from drusen and of their relatives, and by studying the histologic data, the dynamics of the process were revealed. A classification of drusen according to depth of location is suggested. Hidden, deep and amputated drusen are distinguished. The conclusion is that deep and hidden drusen are the most frequent cause of pseudopapilledema.
