Comments and Conclusions

  • A vitreous hemorrhage under the posterior hyaloid is also known as a preretinal hemorrhage or subhyloid hemorrhage.1
  • The hemorrhage is often boat-shaped due to gravity when the blood is trapped in the potential space created between the posterior hyaloids and inner limiting membrane.1
  • Treatment is determined by the underlying etiology of the hemorrhage. If it is due to neovascularization from proliferative retinopathy, laser PRP is performed to stunt the growth of new blood vessels. Anti-VEGF agents can also be used to slow the growth of new blood vessels if PRP is not able to be performed immediately.1
  • There was debate on whether aspirin or other anticoagulants increase the risk of developing vitreous hemorrhages. However, two studies have shown that the use of aspirin does not increase the risk of developing vitreous hemorrhages.2,3
