Optic nerve head (ONH) drusen are acellular calcified concretions. Buried drusen manifests as pseudopapilledema. The compressive effects of ONH drusen can rarely precipitate central retinal vein occlusion (CRVO). The superimposition of pseudopapilledema on disc edema in CRVO poses a diagnostic dilemma. A 40-year-old female without systemic comorbidities presented with resolving CRVO. An exhaustive systemic workup revealed no abnormalities. Ultrasonography demonstrated buried ONH drusen. This unusual etiology must be considered in a young patient in the absence of systemic risk factors, persistence of "nasally conspicuous" disc elevation, and presence of peripapillary hemorrhages. Ultrasonography must be incorporated in the diagnostic armamentarium in a young patient with CRVO.
视神经乳头（ONH）玻璃疣是无细胞的钙化凝结物。埋藏性玻璃疣表现为假性视乳头水肿。ONH玻璃疣的压迫作用很少会引发视网膜中央静脉阻塞（CRVO）。CRVO中假性视乳头水肿与视盘水肿的叠加造成了诊断困境。一名无全身性合并症的40岁女性出现CRVO缓解情况。全面的全身检查未发现异常。超声检查显示有埋藏性ONH玻璃疣。在没有全身性危险因素、“鼻侧明显”视盘隆起持续存在以及视乳头周围出血的年轻患者中，必须考虑这种不寻常的病因。对于患有CRVO的年轻患者，超声检查必须纳入诊断手段中。
