PurposeTo describe multimodal imaging features of choroidal osteoma (CO) complicated by choroidal neovascularization (CNV) and focal choroidal excavation (FCE).MethodsPatients presenting with CO and CNV between January and October 2016 were considered for this study. Diagnosis of CO was confirmed by ultrasound examination. All patients underwent multimodal imaging including optical coherence tomography (OCT), swept-source OCT angiography (DRI OCT Triton, Topcon, Inc., Tokyo, Japan) and fluorescein angiography (Spectralis HRA+OCT; Heidelberg Engineering, Heidelberg, Germany).ResultsTwo patients (one with bilateral CO) were included in the study. OCT showed a FCE in two eyes of two patients (one in correspondence of the CNV and the other adjacent to the CNV). OCT-A demonstrated presence of microvascular flow within neovascular network of the CNVs. Decalcification of the tumor was noted in correspondence of one eye with FCE.ConclusionsFCE may be found in eyes with choroidal osteoma and CNV. OCT-A was a valuable tool for detection of CNV complicating choroidal osteoma. Decalcification of choroidal osteoma may represent a common pathogenic pathway for development of FCE and CNV in choroidal osteoma.

“…CNV was detected with OCTA in areas where it was undetectable on the FFA due to the diffuse hyperfluorescence. Of note, there have been publications describing CNV secondary to CO detected by OCTA [ 9 , 10 ]. In our study, the CNV showed regression of lesion size after treatment, same as Szelog et al reported [ 9 ].…”

PurposeChoroidal osteoma (CO) frequently leads to progressive visual loss due to complications of secondary choroidal neovascularization (CNV).We report herein the function of optical coherence tomography angiography (OCTA) in observation of CO complicating CNV.MethodsA 25-year-old female presented to our hospital with chief complaint of sudden unilateral visual acuity decrease for one week, with metamorphopsia in the left eye. Her best corrected visual acuity was 0.12 in the left eye. Then complete ophthalmological examinations including fundus photography, B-scan ultrasound, fundus fluorescent angiography, and spectral-domain optical coherence tomography (SD-OCT) were performed. She was diagnosed as CO on the basis of these results. But the diagnosis could not explain the sudden visual loss and submacular hyperreflective lesion by SD-OCT. Furthermore, she underwent OCTA and indocyanine green angiography.ResultsA diagnosis of classic juxtafoveal CNV secondary to CO was made eventually. Then she was treated with an intravitreous injection of ranibizumab twice. The visual acuity got better and better during the treatment, and the efficacy was stable, giving rise to both subjective and anatomic improvement.ConclusionsOptical coherence tomography angiography has the advantage of varying the segmentation and scrolling through the different retinal layers, and layer-specific observation of blood flow in each layer. In addition, OCTA can measure the vessel area change of CNV and provide a better appreciation of CNV, observing the efficacy more elaboratively and quantizedly. OCTA makes promising noninvasive identification of the CO-related CNV.

“…Nearly one-third of patients with CO are complicated by a CNVM. 4 It occurs secondary to decalcification along with disruption of the RPE and Bruch's membrane complex, allowing growth of new vessels. 5 CNVM may present with hemorrhage, subretinal fluid and NSD, requiring some form of treatment.…”
