The long-term follow-up of a highly myopic patient with a macular vortex vein.

We followed a highly myopic patient with a macular vortex vein for 11 years. His refraction was -12D OU at age 10 years when the vein was first observed ophthalmoscopically in the left eye. Eleven years later, his myopia had progressed (4 diopters OD; 8 diopters OS), and the axial lengths were elongated (+1.8 mm OD; +2.7 mm OS). The macular vortex vein was dilated and tortuous. Indocyanine green angiography revealed the outflow route of this vein in the posterior pole, where both nasal and temporal posterior choroidal venous blood collected. Computed tomography showed that the vein left the eyeball directly and coursed along the optic nerve 5 mm posterior to the optic disc. A major collecting channel of posterior choroid outflow in some highly myopic eyes, a macular vortex vein may be formed at a relatively early age, and continue to enlarge, with elongation of axial length and progression of myopia.
