Objective
Natural course of central retinal vein occlusion (RVO) has a poor prognosis. Finally loss of visual acuity is a major problem. New approaches for treatment like surgical decompression have been suggested.
Methods
In a clinical trial 10 patients with ischemic CRVO underwent surgical decompression. Radial optic neurotomy (RON) was performed 1-5 months after retinal vein occlusion. Follow-up-time was 8-18 months. Visual acuity, retinal perfusion and incidence of typical complications after RVO were of main interest in scientific evaluation.
Results
Visual acuity improved significantly after surgical procedure. For ischemic CRVO EDTRS charts increased from 20/125 to 20/50. Surgical or late complications did not occur. Recovery of retinal blood flow during fluoresceine angiography was investigated in 75% of the patients and correlated with good functional results.
Conclusions
For patients with retinal vein occlusion RON seems to be a safe and feasible procedure. Results suggest the potential to improve visual acuity while reducing typical complications.
