FIG 1. The SOVs (arrows) are located under the superior rectus muscles. Three examples of the diameters of the SOVs are illustrated.
A, SOV 1 mm in diameter in a 57-year-old woman with a CSF pressure of 108 mm H2O.
B, SOV 3 mm in diameter over the left side and SOV 2 mm in diameter over the right side in a 32-year-old women with a CSF pressure of 230 mm H2O.
C, SOV 5 mm in diameter in a 34-year-old man with a CSF pressure of 245 mm H2O.
