Branch retinal vein occlusion and vitreovascular traction: a preliminary spectral domain OCT case–control study

Abstract

A common firm vitreous adhesion at the obstruction site is reported herein, pointing out the possible role of vitreovascular traction in the etiology of some cases of BRVO. Likewise, although not all BRVO cases can be explained by this pathogenic mechanism, an attached posterior vitreous cortex might be a cofactor in the origin of this entity.

The Role of Inflammation in the Pathogenesis of Macular Edema Secondary to Retinal Vascular Diseases

“…Although the pathogenesis of ME when associated with RVO (RVO-ME) is not fully understood, increased rigidity of a crossing artery as a result of an atherosclerotic process has been suggested to cause compression of the underlying vein, provoking turbulent blood flow, endothelial damage, and thrombus formation [ 11 ]. Likewise, a common vitreous adhesion at the obstruction site has also been reported, suggesting a possible role of vitreovascular traction in the etiology of some cases of BRVO [ 12 , 13 ].…”

A retrospective study of the influence of the vitreomacular interface on macular oedema secondary to retinal vein occlusion

“…A subsequent study done by Avunduk et al 11 in 1997 indicated that a total PVD reduced the incidence and persistence of both retinal neovascularization and ME in eyes with RVO. These studies provide precedence in investigating the use of modern clinical diagnostics and treatments that could induce PVD to inhibit persistent ME secondary to RVO 12 13…”

Letter to the Editor: Vitreoretinal Traction, Extrafoveal Traction, Vascular Insufficiency, and Macular Edema

“…Direct association between these noncentral extrafoveal tractional membranes and the central macular edema was confirmed by using the full-field 3-D SD-OCT approach that included 360° viewing of the examined fields by video clips, as documented 1,2 and summarized. 3 Such association was later reported by others in DME 4 and BRVO. 5 Nowadays, new OCTs enable 3-D wide-field imaging, which would facilitate diagnosis of noncentral trac-tion and its association with the central macula pathology.…”
