Prognosis is poor and loss of vision is a severe risk. New approaches for treatment like systemic fibrinolysis and s urgical procedures have been suggested. Patients and Methods: In a clinical tria l 8 patients with ischemic CRVO underwent surgical decompression. Strict criteri a of inclusion were maintained. Radial optic neurotomy (RON) was performed 0.25 -5 months after retinal vein occlusion. Follow up-time was 3 months. Visual ac uity and incidence of typical complications after RVO were the main points of in terest in our scientific evaluation. Results: Visual acuity improved significant ly after the surgical procedure. For ischemic CRVO EDTRS charts increased from l ogMAR 1.0 (decimal 0.17) to 0.68 (0.30) at 3 months after surgery. Surgical or e arly complications did not occur within 3 months. The recovery of retinal blood flow during fluorescein angiography was investigated in 75%of the patients. A r esolution of non perfusion-areas could be detected in 50%of the eyes. Conclusi ons: For patients with retinal vein occlusion RON seems to be a safe and feasibl e procedure. The results indicate the potential to improve visual acuity while t ypical complications due to surgery or vein occlusion did not occur during the f irst three months.展开更多
