Abstract
PURPOSE: To report a case of a choroidal macrovessel imaged using enhanced depth imaging spectral domain optical coherence tomography (EDI-OCT) and describe the choroidal features. CASE REPORT: a 42-year-old man presented with metamorphopsia. Multimodal imaging, including color fundus photography, near-infrared reflectance, and EDI-OCT was used to describe a choroidal macrovessel. RESULTS: Initial ophthalmic examination revealed a serpentine-shaped subretinal pattern deep to the retina near the fovea. When the color image was subjected to a red filter, a large diameter vessel could be seen coursing from the fovea to the temporal macula. EDI-OCT of the choroidal macrovessel revealed a thickened choroid and mild deformation of both the ellipsoid zone and the choroidal-scleral junction. En face spectral domain optical coherence tomography at the level of the choroid demonstrated the anomalous vessel. CONCLUSION: EDI-OCT and en face optical coherence tomography, used in conjunction with other imaging modalities, can be used to demonstrate the presence and pattern of a choroidal macrovessel. A thickened choroid and overlying outer retinal indentation was observed in association of the choroidal macrovessel. These imaging tools can help distinguish this condition from other diagnoses with a similar appearance, such as ophthalmomyiasis.
