Long-Term Outcomes of Vitrectomy With or Without Arteriovenous Sheathotomy in Branch Retinal Vein Occlusion

Abstract

Our findings suggest that vitrectomy with or without arteriovenous sheathotomy may improve the long-term functional and tomographic outcomes for patients with macular edema secondary to BRVO. Although additional arteriovenous sheathotomy did not lead to a distinct functional benefit in this series, early surgical intervention may result in better visual outcomes.

Inflammatory Factors in Major and Macular Branch Retinal Vein Occlusion

“…In addition, Saika et al [8] reported that vitrectomy combined with surgical posterior vitreous detachment was effective for macular edema in BRVO patients. Moreover, it has been reported that macular edema and visual acuity can be improved in patients with BRVO by this procedure [9,10]. Accordingly, we performed vitrectomy more than 3 months after the onset of BRVO in patients with CME.…”

Association of Inflammatory Factors With Macular Edema in Branch Retinal Vein Occlusion

“…Finally, PPV reduces the intraocular levels of various other inflammatory factors in addition to VEGF, 30 and this may be another mechanism by which it alleviates macular edema in patients with BRVO. In fact, it has been reported 31,32 that PPV improves both functional and tomographic outcomes in patients with BRVO and macular edema. Accordingly, we performed PPV in patients with clinically detectable diffuse macular edema or cystoid macular edema more than 3 months after the onset of BRVO.…”

Management of Retinal Vein Occlusion – Consensus Document

“…Peeling of the ILM may be reserved for clinical situations in which other modalities of treatment, namely the intravitreal injection of antiedematous (steroids) or anti-VEGF drugs, have failed to achieve a satisfactory improvement in vision, and in which the blood perfusion of the macula physiologically allows an increase in VA [112,131,133,134,135,136,137,138,139,140,141]. …”
