Retinal Vein Occlusion
Just like any other portion of our body, the retina in our eyes has both arteries and veins which are responsible for the blood circulation, delivery of oxygen and nutrients, and the removal of wastes.
Sometimes, one of these blood vessels develops a blockage. This more commonly happens in the veins than the arteries. Depending upon location of the vein blockage, visual loss could be central or peripheral, mild or severe. Fluorescein Angiography may be required to help characterize the type of blood vessel occlusion and to guide treatment recommendations.
Laser photocoagulation is often employed if there is any leakage and swelling of the central retina (macular edema) or abnormal blood vessel growth (neovascularization) that has developed as a consequence of a retinal vein occlusion.

The injection of steroids and anti-VEGF agents in the eye has also been demonstrated to be very useful in the treatment of macular edema associated with branch and central retinal vein occlusions. We currently utilize these treatments.
