“…32 Traction through vitreous fibres to the Muller cells of the macula may predispose this area to the development of oedema as well. 22,33 Pars plana vitrectomy has been found to be successful in the resolution of diabetic macular oedema or macular oedema due to venous occlusions. [34][35][36][37] If so, pars plana vitrectomy without sheathotomy may be a better control for sheathotomy procedures.…”

“…To analyse and compare the studies on sheathotomy is difficult because of differences and variations of methodology.

Purpose To report the effects of arteriovenous adventitial sheathotomy on anatomical and functional improvements in patients with macular oedema due to branch retinal vein occlusion (BRVO). Methods Pars plana vitrectomy and arteriovenous sheathotomy was performed on 11 patients with BRVO who had vision loss due to macular oedema. Ten patients with macular oedema due to BRVO and who have been treated with grid laser photocoagulation were included in the control group. The measurement of visual acuity with ETDRS chart was taken preoperatively and at 1, 3, 6, and 9 months follow-up in the study group and at 1, 3, 6, and 9 months after grid laser in the control group. Results The mean preoperative logMAR visual acuity was 0.8470.3 in the surgical group and 1.0670.4 in the control group. The postoperative mean logMAR visual acuity was 0.4170.2, 0.4070.2, 0.4070.3, and 0.3670.3 at 1, 3, 6, and 9 months follow-up, respectively. In the control group the postlaser mean logMAR visual acuity was 0. 9270.3, 0.8770.4, 0.8570.3, and 0.8270.3 at 1, 3, 6, and 9 months follow-up, respectively. The improvements of visual acuity in both groups were statistically significant when compared to pretreatment (P ¼ 0.003 and P ¼ 0.007 at 9 months in the study and control group, respectively). Conclusion Arteriovenous sheathotomy for decompression of BRVO in patients who have vision loss due to macular oedema was safe and effective for anatomical and functional improvement and resulted in significantly better visual outcomes than a matched control group of laser-treated eyes.

“…Also, Cahill et al [52] reported a complete resolution of cystoid macular edema and postoperative vision improvement in one third of the patients after A-V sheathotomy. However, Yamamoto et al [53] retrospectively studied 16 eyes that underwent PPV with sheathotomy and 16 eyes that underwent only PPV for macular edema secondary to BRVO. They reported that there was no significant difference in the improvement of macular function between the two groups at any postoperative period and also there were no differences in the functional and morphologic improvements between patients with and without sheathotomy.…”

Retinal vein occlusion (RVO) is the second most common vascular disease after diabetic retinopathy. Although its high frequency, mechanisms underlying RVO and optimal treatment strategies are still controversial. There are various treatment modalities for retinal vein occlusion including observation, systemic treatments, intravitreal agents, laser photocoagulation, fibrinolytic treatment and surgical approaches. Despite most of the treatment strategies are directed at secondary complications of RVO that affect vision including macular edema and retinal neovascularization, some treatment options also have the ability to create a bypass around the obstructed retinal vein and to decrease the raised venous hydrostatic pressure. The aim of this review is to describe the outcomes of fibrinolytic and surgical treatment modalities for RVO.

“…[4][5][6][7][8][9][10][11][12] The surgery has been reported to be associated with reduction in central macular thickness and improved visual acuities. [4][5][6][7][8][9][10][11] Multifocal electroretinography (mfERG) has been used for objective functional assessment of many retinal diseases since Sutter and Tran 13 first introduced the method in 1992. Unlike fullfield ERG, mfERG allows simultaneous measurements of multiple retinal responses at different locations, enabling topographic mapping of the retinal function in the central retina.…”

Purpose-To evaluate the influence of arteriovenous (AV) sheathotomy on retinal function with central multifocal electroretinography (mfERG) in eyes with macular edema secondary to branch retinal vein occlusion (BRVO).Methods-Fifteen patients (15 eyes) who underwent AV sheathotomy for macular edema secondary to BRVO were included in the study. Best-corrected visual acuity and mfERG responses from the most central seven hexagons were analyzed before and 6 months after the operation.Results-The mean preoperative Early Treatment Diabetic Retinopathy Study (ETDRS) score ± SD was 34.1 ± 12.7 letters (Snellen equivalent, 20/50) and significantly improved up to 40.5 ± 10.9 letters (Snellen equivalent, 20/40) at 6 months after AV sheathotomy (P = 0.027, Wilcoxon signed rank test). The mean preoperative P1 amplitude ± SD of the most central 7 hexagons was 39.30 ± 10.86 nV/deg 2 for the affected eye versus 47.72 ± 6.67 nV/deg 2 for the normal fellow (control) eye (P = 0.013, Mann-Whitney U test) and significantly increased up to 50.71 ± 15.58 nV/deg 2 at 6 months after the operation (P = 0.014, Wilcoxon signed rank test). Significant correlations between preoperative and postoperative ETDRS score and preoperative P1 amplitude were present (r = 0.929, P < 0.001; r = 0.768, P = 0.001; respectively [Spearman correlation]).Conclusions-AV sheathotomy improved macular function and anatomical outcome as measured by ETDRS score and mfERG responses in patients with macular edema due to BRVO. Keywords arteriovenous sheathotomy; branch retinal vein occlusion; multifocal electroretinography Branch retinal vein occlusion (BRVO) is a common retinal vascular disease occurring in a significant number of individuals older than 50 years of age. 1,2 The most common cause of visual disturbance in BRVO patients is macular edema, which has been described in 60% of patients. 3 Arteriovenous (AV) sheathotomy is one of the surgical methods proposed to treat
