Sudden visual loss secondary to an orbital varix.
A 45-year-old man presented with precipitous loss of vision and rapidly changing field defects in one eye. Computerized tomography and B-scan ultrasonography revealed a small orbital mass adjacent to the optic nerve. This was removed via lateral orbitotomy. On pathologic examination it was diagnosed as a small orbital varix. Drs. Frederick C. Blodi and Stephen Trokel comment on the case.
