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

Abstract: Optic disk drusen are relatively benign lesions of the eye but can cause visual symptoms and may occasionally mimic papilledema on funduscopy We studied the range of sonographic findings and determined if sonography can be used to diagnose this condition in the absence of typical funduscopic findingsSonography of the eyes was performed in 12 patients with known or suspected optic disk drusen by using a 10-MHz transducer Optic disk drusen were diagnosed clinically in 16 of the 24 eyes The funduscopic appearance was typical in 11 eyes and atypical in five eyes In these five patients, the diagnosis was made on the basis of an abnormal appearance of the disk and either a strong family history of drusen (four patients) or funduscopic findings that were typical of drusen in the opposite eye (one patient)The head of the optic nerve was abnormal in 19 of 24 eyes on sonography and in 16 on funduscopy In all cases with abnormal findings on sonograms, an ovoid echogenic lesion was evident at the junction of t
