Purpose:
Practical application of radial optic neurotomy for patients with central retinal vein occlusion, based on our initial experience.
Material And Methods:
Three patients with central retinal vein occlusion underwent pars plana vitrectomy with radial optic neurotomy at the nasal site of the optic disc.
Results:
Improvement of visual acuity by one or three lines in two of three patients who underwent RON. Partial clearing of retinal haemorrhages and retinal oedema occurred in all cases. No serious complications developed intra- and postoperatively.
Conclusions:
Radial optic neurotomy remains a controversial but also promising treatment for eyes with CRVO. Further study is necessary to establish RON as a standard therapy for CRVO.
