title: [Drusen in children: three case studies].
abstract: We report three cases of optic disc drusen in children. The children were 5 months, 10 years, and 11 years old. Two of them were male. The optic disc drusen was unilateral in two cases and bilateral in one case. One child had a history of Down syndrome and another one a history of Alagille syndrome. The third child had no particular general history but he had unilateral high myopia with optic disc drusen in the same eye. Fundus examination showed pseudopapilledema in all three cases; the disc appeared elevated and its margins were blurred. Ultrasonography of the eye demonstrated optic disc drusen in the three cases. Optic disc calcification on CT scan was identified in only one case. In children, optic disc drusen are often buried, leading to pseudopapilledema appearance of the optic disc. Ultrasonography is highly sensitive in detecting optic disc drusen, making more expensive investigations unnecessary.
