TLDR
Grid laser photocoagulation is an established treatment for macular edema in a particular group of patients with BRVO, while promising results for this condition are shown by intravitreal application of steroids or new vascular endothelial growth factor inhibitors.
Abstract
In branch retinal vein occlusion (BRVO), abnormal arteriovenous crossing with vein compression, degenerative changes of the vessel wall and abnormal hematological factors constitute the primary mechanism of vessel occlusion. In general, BRVO has a good prognosis: 50–60% of eyes are reported to have a final visual acuity (VA) of 20/40 or better even without treatment. One important prognostic factor for final VA appears to be the initial VA. Grid laser photocoagulation is an established treatment for macular edema in a particular group of patients with BRVO, while promising results for this condition are shown by intravitreal application of steroids or new vascular endothelial growth factor inhibitors. Vitrectomy with or without arteriovenous sheathotomy combined with removal of the internal limiting membrane may improve vision in eyes with macular edema which are unresponsive to or ineligible for laser treatment.

Randomized, sham-controlled trial of dexamethasone intravitreal implant in patients with macular edema due to retinal vein occlusion.

TL;DR: In this paper, the safety and efficacy of dexamethasone intravitreal implant (DEX implant; OZURDEX, Allergan, Inc., Irvine, CA) compared with sham in eyes with vision loss due to macular edema (ME) associated with BRVO or central retinal vein occlusion (CRVO).

Natural History of Central Retinal Vein Occlusion: An Evidence-Based Systematic Review

TL;DR: Visual acuity generally improved in eyes with BRVO without intervention, although clinically significant improvement beyond 20/40 was uncommon, and the best available evidence from the literature indicated this was uncommon.

Comprehensive analysis of inflammatory immune mediators in vitreoretinal diseases.

TL;DR: Major three factors: IL-6, IL-8, and MCP-1 were strongly correlated with each other indicating a common pathway involved in inflammation process in vitreoretinal diseases.

Branch retinal vein occlusion: epidemiology, pathogenesis, risk factors, clinical features, diagnosis, and complications. An update of the literature.

TL;DR: An update of the literature about the classification, epidemiology, pathogenesis, risk factors, clinical features, and complications of branch retinal vein occlusion (BRVO), the second most common retinal vascular disorder after diabetic retinopathy, is made.

Mutation in blood coagulation factor V associated with resistance to activated protein C

TL;DR: It is demonstrated that the phenotype of APC resistance is associated with hetero-zygosity or homozygosity for a single point mutation in the factor V gene which predicts the synthesis of a factor V molecule that is not properly inactivated by APC.

Vascular Endothelial Growth Factor in Ocular Fluid of Patients with Diabetic Retinopathy and Other Retinal Disorders

TL;DR: The data suggest that VEGF plays a major part in mediating active intraocular neovascularization in patients with ischemic retinal diseases, such as diabetic retinopathy and retinal-vein occlusion.

Hyperhomocysteinemia: an independent risk factor for vascular disease.

TL;DR: Hyperhomocysteinemia is an independent risk factor for vascular disease, including coronary disease, and in most instances is probably due to cystathionine beta-synthase deficiency.

Homocysteine and atherothrombosis

TL;DR: In 1969, McCully reported autopsy evidence of extensive arterial thrombosis and atherosclerosis in two children with elevated plasma homocyst(e)ine concentrations and homocysteine thiolactone, and it has recently become clear that hyperhomocyst (e)inemia is an independent risk factor.

Familial thrombophilia due to a previously unrecognized mechanism characterized by poor anticoagulant response to activated protein C: prediction of a cofactor to activated protein C.

TL;DR: A previously unrecognized mechanism for familial thromboembolic disease is described that is characterized by poor anticoagulant response to activated protein C (APC), and as two additional, unrelated cases with thrombosis and inherited poor antICOagulants response to APC are identified, this may constitute an important cause for familialThrombophilia.
