研究目的
To evaluate the EDI-OCT features of two cases of choroidal osteoma with neovascular membranes.
研究成果
EDI-OCT revealed consistent features in choroidal osteoma with neovascular membranes, including compression of choriocapillaris, disorganization of medium and large vessel layers, a subtle sponge-like pattern, multiple intralesional layers, and intrinsic transparency with sclerochoroidal junction visibility. EDI-OCT is a valuable tool for differential diagnosis and studying secondary neovascularizations in such cases.
研究不足
The study is limited to only two cases, which may not be representative of all choroidal osteoma cases. The sponge-like pattern was subtle and not fully visible in all areas, particularly under neovascular membranes with fibrotic components.
1：Experimental Design and Method Selection:
Case study design using enhanced depth imaging optical coherence tomography (EDI-OCT) to image choroidal osteomas with secondary neovascular membranes.
2：Sample Selection and Data Sources:
Two newly diagnosed cases of choroidal osteoma with recent visual loss.
3：List of Experimental Equipment and Materials:
Cirrus Carl Zeiss OCT for SD-OCT including EDI-OCT, fluorescein angiography, and ultrasonography.
4：Experimental Procedures and Operational Workflow:
Patients underwent fundus examination, SD-OCT with EDI-OCT, fluorescein angiography, and ultrasonography to assess choroidal features.
5：Data Analysis Methods:
Qualitative analysis of EDI-OCT images for features such as compression of choriocapillaris, disorganization of vessel layers, sponge-like pattern, and visibility of sclerochoroidal junction.
