The ROVO study is a prospective, placebocontrolled and randomised study designed to evaluate
the effect of radial optic neurotomy in central vein occlusion, versus triamcinolone
acetonide. 240 patients with a visual acuity < 0.5 Snellen will be randomised. Patients are
treated with either RON, or a single intravitreal injection of 4 mg triamcinolone acetonide,
or a placebo treatment - a "sham" injection of intravitreal triamcinolone. Patients will be
examined regularly over a period of one year.
Best corrected visual acuity for far and near, as well as clinical examinations, fluorescein-
and indocyanine green angiograms, optical coherence tomography, and perimetry, are performed
pre- and postoperatively.
