A 33-year-old gentleman was presented with metamorphopsia in the left eye due to choroidal osteoma (CO) complicated by choroidal neovascular membrane (CNVM). Optical coherence tomography angiography (OCTA) proved to be a valuable, noninvasive tool in monitoring treatment response of CNVM. The tumor subsequently underwent decalcification over a period of 4 years. In addition, SS-OCT scans were instrumental in documenting the natural course of the tumor and focal choroidal excavations (FCE), which were found in correspondence with tumor decalcification. Close follow-up is warranted in FCE, secondary to decalcification of CO, as CNVM has been documented to occur on the slope or bottom of eyes with FCE.
一位 33 岁男性因脉络膜骨瘤（CO）合并脉络膜新生血管膜（CNVM）导致左眼出现视物变形。光学相干断层扫描血管造影（OCTA）被证明是监测 CNVM 治疗反应的一种有价值的非侵入性工具。该肿瘤随后在 4 年内经历了脱钙过程。此外，SS-OCT 扫描有助于记录肿瘤和局灶性脉络膜凹陷（FCE）的自然病程，这些凹陷与肿瘤脱钙相对应。由于 FCE 处 CO 脱钙后可能发生 CNVM，因此需要密切随访 FCE。
