  • Abstract
  • Look Inside

Background: Indocyanine green (ICG) studies showed the presence of posterior routes of choroidal blood outflow in about one-fourth of eyes with high myopia. The so-called macular vortex veins would need further clarification regarding their retrobulbar course.

Material and methods: Seventeen eyes with macular vortex veins were studied by ICG angiography. One eye was examined by helical computed tomography with injection of radiopaque material.Results: ICG angiography showed the short posterior ciliary artery to enter the choroid at the site of macular vortex veins in 14 eyes, 82%. CT angiography showed the macular vortex vein to drain into the vascular plexus around the optic nerve.

Conclusion: Macular vortex veins may have developed as dilatation of posterior ciliary veins to compen-sate the enlarged eyeball in high myopia.
