Purpose: The Authors describe clinical results of radial optic neurotomy (RON) and transconjunctival sutureless vitrectomy (TSV) using 25–gauge system in the treatment of central retinal vein occlusion (CRVO). Methods: 15 consecutive patients with ischemic or indeterminate CRVO, with initial VA 20/200 or worse, underwent radial optic neurotomy with "TSV 25 System" (B&L). All patients were operated by the same surgeon with the same technical procedure and followed for 2 to 12 months. Preoperative and postoperative uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BCVA), fluorescein angiography, optical coherence tomography were assessed. Results: An improvement in anatomic conditions was seen, with decrease of macular edema and intraretinal hemorrhages, was observed in 12 cases; 7 patients showed VA improvement. A conspicuous intraoperative hemorrhage from the site of RON was observed in one patient.Conclusions: Our preliminary results suggest that RON could be a promising surgical technique in improving VA in patients with CRVO. Further randomized controlled studies are needed to investigate the effectiveness and safety of this treatment for CRVO.
