Radial optic neurotomy for management of hemicentral retinal vein occlusion.

Objective: To evaluate the effect of radial optic neurotomy on visual acuity (VA) and foveal thickness in patients with hemicentral retinal vein occlusion.

Methods: A prospective noncomparative case series of 13 eyes in 13 patients with hemicentral retinal vein occlusion and a preoperative VA of 20/60 or less from a total of 232 retinal vein occlusions diagnosed. All patients underwent pars plana vitrectomy, posterior hyaloid dissection, and radial optic neurotomy at the nasal border of the optic disc.

Management of macular edema in branch retinal vein occlusion with sheathotomy and recombinant tissue plasminogen activator.

Purpose: The common adventitial sheath that surrounds the retinal venule and arteriole at the crossing site plays a crucial role in branch retinal vein occlusion (BRVO). The purpose of this study was to report the surgical recanalization of the occluded vein using a bimanual technique and recombinant tissue plasminogen activator (tPA) and its effect on final visual acuity.

Methods: Arteriovenous sheathotomy was performed, using a bimanual technique, followed by fluid-air exchange and injection of 25 mg of recombinant tPA over the area of the occluded vein.
