متن کاملSonography in optic disk drusen: imaging findings and role in diagnosis when funduscopic findings are normal.

We studied the range of sonographic findings and determined if sonography can be used to diagnose this condition in the absence of typical funduscopic findings. SUBJECTS AND METHODS Sonography of the eyes was performed in 12 patients with kno...
