Retinitis pigmentosa 2

  1. 1. Retinal Vein Occlusion Symptoms :  The visual symptoms can vary in severity, and are dependent on whether the central retinal vein or a branch retinal vein is involved.  Recovery from a central vein occlusion is much less likely since it affects the macula.  This problem appears equally in males and females  It is more common after the age of 60.
  2. 2. Symptoms  Sudden onset  Blurred or missing area of vision (if a branch vein is involved)  loss of central vision (if a central vein is involved)     
  3. 3. Retinal Vein Occlusion    A obstructed blood vessel, causing hemorrhages in the retina.  Swelling and ischemia (lack of oxygen) of the retina as well as glaucoma are fairly common complications.
  4. 4. Detection and Diagnosis  by ophthalmoscope.  Fluorescein angiography
  5. 5. Treatment  To treat the secondary complications.  LASER  The following are common risk factors for vein occlusion:  ·Diabetes  ·Hypertension  ·Cardiovascular disease  
  6. 6. Retinal Artery Occlusion
  7. 7. Signs and Symptoms  Transient loss of vision prior to the artery occlusion (in some cases)
  8. 8. Signs and Symptoms  Transient loss of vision prior to the artery occlusion (in some cases)
