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.
