Choroidal osteoma (CO) is a rare, benign ossifying lesion of the choroid found in otherwise healthy patients. Although associated with good visual prognosis, tumor deossification in choroidal osteoma has been linked with vision loss, presumably due to overlying photoreceptor degeneration. Here the authors present a case of CO in an elderly male demonstrating tumor deossification and photoreceptor atrophy during a 3-year follow-up using enhanced depth imaging optical coherence tomography (EDI-OCT). Visual acuity was maintained due to the tumor's noncentral location. Patients with CO should undergo regular imaging with EDI-OCT to screen for tumor deossification and impending vision loss.

脉络膜骨瘤（CO）是一种罕见的、良性的脉络膜骨化性病变，见于其他方面健康的患者。尽管其视觉预后良好，但脉络膜骨瘤的肿瘤脱钙与视力丧失有关，推测是由于上方的光感受器变性所致。本文作者报告了一例老年男性脉络膜骨瘤病例，该病例在3年随访期间使用增强深度成像光学相干断层扫描（EDI-OCT）显示了肿瘤脱钙和光感受器萎缩。由于肿瘤位于非中心位置，视力得以维持。患有脉络膜骨瘤的患者应定期进行EDI-OCT成像检查，以筛查肿瘤脱钙和即将出现的视力丧失。[《眼科手术、激光与视网膜成像》。2017；48：87-90。]
