title: Retinal hemorrhages in posterior vitreous detachment.
abstract: Detachment of the posterior vitreous can cause clinically significant retinal hemorrhage. Two patients with acute posterior vitreous detachment had massive retinal hemorrhages overlying the optic disks. These absorbed in time without sequealae. A third patient had numerous small blot hemorrhages scattered near the optic disk and macula. A fourth patient presented with a small macular hemorrhage causing temporary visual loss. All patients had moderately severe myopia and were in good health without hypertension or diabetes. There was no history of trauma or Valsalva maneuver. Hematologic and coagulation studies were normal. These cases indicate that retinal hemorrhages due to posterior vitreous detachment may be strikingly large, multiple, and, when involving the macula, cause temporary visual loss.
