[Subhyaloid hemorrhage following a Valsalva maneuver].
The authors present a case of a 48-year-old man complaining of a temporal nasal scotoma without visual impairment, occurring after sneezing. The perception of scotoma is explained by a retrohyaloidal hemorrhage sparing the optical axis. The hemorrhage, resulting from the break of two superior temporal veins, disappeared within 8 months without after effects. The authors explain the responsible mechanisms and analyze the different cases published in the literature.
