Drusen

• Optic disc drusen develops over time. Abnormal material collects and calcifies in the optic nerve head. The condition is not associated with any type of disease so its occurrence is generally unexplained. Usually diagnosed during a routine exam, drusen may have no symptoms or minor symptoms like flickering, graying, or subtle vision loss. In most cases, patients will retain all or most central vision, yet regular exams are suggested to monitor the progression and access possible vision loss. In rare instances, the occurrence of choroidal neovascular membrane will develop next to the optic disc. These new blood vessels are prone to bleeding, resulting in abrupt loss of vision. However, prompt treatment of this particular possibility will avoid complications due to bleeding.
  
  Patients diagnosed with optic nerve drusen should also monitor intraocular pressure. In instances where loss of vision is occurring, medication to decrease intraocular pressure may be helpful and should be considered. When central visual acuity is in jeopardy, laser photocoagulation may need to be considered.
  
  Since this condition is primarily asymptomatic, rarely dangerous, and its cause is not clear, the treatment possibilities are scarce and only considered in the event of major vision loss.
