Abstract:
PURPOSE: To evaluate the characteristics of choroidal nevus using the enhanced depth imaging spectral domain optical coherence tomography (EDI SD-OCT), with a comparison to the B scan ultrasound (BUS) findings. METHODS: Medical records of 124 eyes of 124 choroidal nevus patients were reviewed retrospectively. All patients underwent fundus photography (FP), EDI SD-OCT, and BUS. RESULTS: Of 124 eyes with choroidal nevus examined by EDI SD-OCT, 43 eyes (35%) displayed good images to study. The most common EDI-OCT imaging features included choroidal shadowing, choriocapillary thinning, retinal pigment epithelial changes, and overlying subretinal fluid. The mean nevus thickness was 817 microm (120-1850 microm) by EDI-OCT compared 1295 microm (780-2400 microm) by BUS. The mean difference in the tumor thickness between two techniques was 475 microm (27-1319 microm) (p < 0.05). CONCLUSIONS: These results have suggested that imaging of choroidal nevus with EDI-OCT shows superior measurement of its characteristics compared with ultrasonography. The clinical utility of this modality is emerging. EDI-OCT is useful in distinguishing suspicious nevi from other chorioretinal lesions, detecting tumor re-growth along the treatment margin, and demonstrating retinal or choroid tumor location.
