MACULAR VORTEX VEIN IN A HIGHLY MYOPIC EYE IMAGED BY OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY.

PURPOSE: To report a case of macular vortex vein imaged with indocyanine green angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography.

METHODS: Observational case report.

RESULTS: A 51-year-old myopic man presented with the complaint of a floater in his left eye for the previous 2 weeks. His visual acuity was 20/25 in the right eye and 20/40 in the left eye. Biomicroscopy was normal. Retinoscopy revealed lattice degeneration and posterior vitreous detachment of both eyes with dilated submacular vasculature in the right eye and submacular hemorrhage in the left eye. Spectral domain optical coherence tomography demonstrated dilated vessels in the choroid of the right eye and a choroidal neovascular membrane in the left eye. Fluorescein angiography and indocyanine green angiography showed a macular vortex vein in the right eye. Optical coherence tomography angiography demonstrated normal vessel densities in the superficial and deep capillary plexuses. No abnormalities were detected in the outer retina or choriocapillaris. Optical coherence tomography angiography delineated the macular vortex vein with a relative flow void in the right eye. His vision remained stable in the right eye.

CONCLUSION: Macular vortex veins may be a prominent, albeit rare, incidental finding in highly myopic eyes. Further studies with application of newer optical coherence tomography angiography modalities, such as swept-source optical coherence tomography angiography, are recommended to improve our understanding and monitoring of these structures.
