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 gears. His refraction was -12 D OU at age 10 years when the vein was f irst observed ophthalmoscopically in the Ir;ft eye. Eleven years later , his myopia had progressed (4 diopters OD; 8 diopters OS), and the ax ial lengths were elongated (+ 1.8 mm OD; + 2.7 mm OS).The macular vort ex vein was dilated and tortuous. Indocyanine green angiography reveal ed the outflow route of this vein in the posterior pole, where both na sal 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 collec ting channel of posterior choroid outflow in some highly myopic eyes, a macular vortex vein may be formed at a relatively early age, and con tinue to enlarge, with elongation of axial length and progression of m yopia.
