Levels of VEGF but not VEGF165b are Increased in the Vitreous of Patients With Retinal Vein Occlusion

The severity of RVO from BRVO to CRVO correlates with an increase of VEGF and the decrease of VEGF165b, indicating a pro-angiogenic shift. Altering the ratio of VEGF165b/VEGF165 might be a feasible approach for treating retinal occlusive diseases.
