Abstract
The high prevalence of cardiovascular disease particularly in the elderly population is associated with retinal vascular disease. Retinal vein occlusions represent severe disturbances of the hypoxia-sensitive neurosensory retina. Acute and excessive leakage leads to the diagnostic hallmarks of retinal hemorrhage and edema with substantial retinal thickening. Advanced diagnostic tools such as OCT angiography allow to evaluate retinal ischemia and identify the risk for late complications and will soon reach clinical routine besides fluorescein angiography. Accordingly, the duration of non-perfusion is a crucial prognostic factor requiring timely therapeutic intervention. With immediate inhibition of vascular leakage, anti-VEGF substances excel as treatment of choice. Multiple clinical trials with optimal potential for functional benefit or a lesser regenerative spectrum have evaluated aflibercept, ranibizumab, and bevacizumab. As retinal vein occlusion is a chronic disease, long-term monitoring should be individualized to combine maintenance with practicability. While steroids may be considered in patients with systemic cardiovascular risk, surgery remains advisable only for very few patients. Destructive laser treatment is an option if reliable monitoring is not feasible. Ophthalmologists are also advised to perform a basic systemic workup to recognize systemic concomitants. The current edition of the EURETINA guidelines highlights the state-of-the-art recommendations based on the literature and expert opinions in retinal vein occlusion.

Abstract
Purpose: To determine the long-term outcomes of vitrectomy for the macular edema associated with a retinal vein occlusion (RVO). Methods: This was a retrospective, consecutive, interventional case series. The intraoperative procedures included internal limiting membrane peeling, arteriovenous sheathotomy, radial optic neurotomy, and intravitreal triamcinolone acetonide injection at the end of the surgery. The main outcome was the best-corrected visual acuity (BCVA). Results: Eight hundred and fifty-four eyes of 854 patients were studied. The eyes consisted of 602 with branch RVO (BRVO), 74 with hemi-central RVO (hemi-CRVO), 87 with nonischemic central retinal vein occlusion (CRVO), and 91 with ischemic CRVO. The mean follow-up period was 68.6 months with a range of 12 to 262 months. The mean BCVA was significantly improved at the final visit (P<0.0001 to 0.0016). The final BCVA improved in 74.4% of the BRVO eyes, in 58.1% of the hemi-CRVO eyes, in 57.4% of the nonischemic CRVO eyes, and in 51.6% of the ischemic CRVO eyes. Multiple regression analysis showed there was no significant relationship between the intraoperative combined procedures and the final BCVA. Conclusions: The results indicate that the type of RVO is significantly associated with the final BCVA, and vitrectomy is a treatment option to improve and maintain BCVA for a long term.

Abstract
Purpose The purpose of this study was to determine the long-term outcomes of intravitreal bevacizumab (IVB) or intravitreal tissue plasminogen activator (tPA) or vitrectomy for macular edema associated with a branch retinal vein occlusion (BRVO). Methods This was a retrospective, interventional case series. Forty-one patients received a single 1.25 mg of IVB injection and followed by pro re nata protocol, 71 patients received a single intravitreal tPA, and 116 patients underwent phacovitrectomy with intraocular lens implantation. Results The baseline characteristics and follow-up periods were not significantly different among the three groups. The mean follow-up period was 55.5 months with a range of 12-160 months. Sixteen patients (39.0%) in the IVB group, 24 patients (33.8%) in the tPA group, and two patients (1.7%) in the vitrectomy group underwent additional surgeries during the follow-up period. The best-corrected visual acuity (BCVA) significantly improved in all groups at 1 year after the initial treatment (all, P<0.0001) and at the final visit (all, P<0.0001). The differences in the BCVA between the three groups were not significant at all times after the initial treatment. Conclusion The three groups led to similar long-term good visual outcomes. However, additional surgeries were performed in more than 30% of patients in the IVB and tPA groups.

Abstract
PURPOSE To evaluate the effectiveness of intravitreal triamcinolone acetonide as primary treatment of macular edema in branch retinal vein occlusion. METHODS Fifteen eyes of 15 patients with macular edema due to branch retinal vein occlusion (Group 1) who received 8 mg/0.2 ml of intravitreal triamcinolone injection as primary treatment were retrospectively evaluated. The control group (Group 2) consisted of 19 eyes of 19 patients who had received laser treatment for macular edema. The main outcome measures included best-corrected visual acuity, intraocular pressure, and macular edema map values of Heidelberg Retinal Tomograph II. RESULTS In Group 1, mean visual acuity improved significantly from a mean logMAR (logarithm of minimal angle of resolution) value of 0.98+/-0.19 at baseline to a maximum of 0.24+/-0.24 during a mean follow-up time of 6.3 months. In the control group, the mean baseline log-MAR visual acuity before laser treatment was 1.02+/-0.22, and it was 0.50+/-0.28 at 6-month examinations. Mean improvement in visual acuity at 1-, 3-, and 6-month examinations was significantly higher in Group 1 when compared with the control group (for each, p<0.001). The mean edema map value of Group 1 significantly decreased by 40% at 6-month examinations when compared with preinjection value (p<0.001). In Group 1, mean increase in intraocular pressure elevation was 19.8% at the 1-month, 26.9% at 3-month, and 5.7% at 6-month visits, but intraocular pressures were under control with topical antiglaucomatous medications. CONCLUSIONS Intravitreal triamcinolone acetonide injection may be a new and promising approach as initial therapy for macular edema due to branch retinal vein occlusion.

Abstract
PURPOSE To evaluate the anatomic and functional outcomes of pars plana vitrectomy combined with internal limiting membrane peeling for recurrent macular edema (ME) due to branch retinal vein occlusion (BRVO) after intravitreal injections of antivascular endothelial growth factor (anti-VEGF) agents. METHODS Twenty-four eyes of 24 patients with treatment-naive ME from BRVO were treated with intravitreal injections of anti-VEGF agents. Recurred ME was treated with pars plana vitrectomy combined with internal limiting membrane peeling. RESULTS After the surgery, ME was significantly reduced at 1 month (P=0.031) and the reduction increased with time (P=0.007 at the final visit). With the reduction in ME, treated eyes showed a slow improvement in visual acuity (VA). At the final visit, improvement in VA was statistically significant compared with baseline (P=0.048). The initial presence of cystoid spaces, serous retinal detachment, or subretinal hemorrhage under the fovea, as well as retinal perfusion status, showed no association with VA improvement. However, the presence of epiretinal membrane showed a significant association with the visual recovery. Although eyes without epiretinal membrane showed visual improvement (-0.10±0.32 in logarithm of the minimum angle of resolution [logMAR]), eyes with epiretinal membrane showed greater visual improvement (-0.38±0.12 in logMAR, P=0.012). CONCLUSION For recurrent ME due to BRVO after anti-VEGF treatment, particularly when accompanied by epiretinal membrane, pars plana vitrectomy combined with internal limiting membrane peeling might be a possible treatment option.

Abstract
In a previous article (July 2004, page 57), Dr Colucciello reviewed nonproliferative and proliferative diabetic retinopathy. In this article, he discusses retinal vascular disease associated with hypertension, which is especially likely to occur in persons with vasculopathic risk factors. Retinal vein occlusion, retinal arterial macroaneurysm, retinal artery occlusion, and carotid artery disease are predictive of progressive systemic vascular disease. Modification of risk factors and prompt identification of retinal vascular disease optimize vision outcomes and preserve quality of life.

Abstract
Purpose. To investigate the efficacy of treatment for macular edema secondary to retinal vein occlusion (RVO) with vitrectomy. Methods. This retrospective study identified patients with macular edema associated with RVO between January 2004 and April 2006. Inclusion criteria were eyes with (1) preoperative visual acuity (VA) of 20/40 or worse, (2) a central foveal thickness (CFT) greater than 250 μm, and (3) vitrectomy with internal limiting membrane and intravitreal triamcinolone acetonide. Each patient had their RVO classified as a major or macular BRVO or hemispheric RVO (HSRVO). Results. Forty-six eyes with major BRVO, 18 eyes with macular BRVO, and 17 eyes with HSRVO were investigated. VA was significantly improved at 24 months after surgery for each group (P < 0.05). Vision in the macular BRVO group 24 months after surgery was significantly better than that in other groups (P < 0.05). For each group, a concomitant reduction of CFT was noted at every time point when compared to preoperative values (P < 0.001). Conclusions. In macular BRVO, the postoperative vision 24 months after surgery was significantly better than the other groups. These findings suggest that additional and earlier treatments might be more important for patients with major BRVO and HSRVO than for those with macular BRVO.

Abstract
Background. To report the outcome of pars plana vitrectomy (PPV) combined with intraoperative endolaser focal photocoagulation (PC) on eyes with idiopathic macular telangiectasis (MacTel) type 1. Methods. This was a retrospective study of two female patients with MacTel type 1 who were resistant to focal photocoagulation, sub-Tenon triamcinolone injection, and/or antiangiogenic drugs. The best-corrected visual acuity (BCVA) was determined, and fluorescein angiography (FA) and spectral domain optical coherence tomography (SD-OCT) were performed before and after surgery for up to 19 months. Results. After surgery, the BCVA gradually improved from 20/100 to 20/20 at 19 months in Case 1 and from 20/50 to 20/13 at 13 months in Case 2. Fluorescein angiography (FA) showed leakage at the late phase, and OCT showed that the cystoid macular edema was resolved and the fovea was considerably thinner postoperatively. Conclusion. Patients with MacTel type 1 who are refractory to the other types of treatments can benefit from PPV combined with intraoperative endolaser focal PC with functional and morphological improvements.

Abstract
Background The purpose of this study was to evaluate visual outcomes of arteriovenous sheathotomy for macular edema due to branch retinal vein occlusion (BRVO). Methods The medical records of 45 eyes from 45 patients who had undergone vitrectomy surgery with arteriovenous sheathotomy for BRVO were studied. Forty-five eyes of 45 patients with a BRVO but without intervention were studied as the control group. The best-corrected visual acuity and central macular thickness were compared between the two groups at baseline and at 1, 3, 6, and 12 months postoperatively. Results Improvement of best-corrected visual acuity was 0.42 logarithm of the minimum angle of resolution (logMAR) units in the sheathotomy group and 0.22 logMAR units in the control group (P=0.007). The mean postoperative central macular thickness was significantly thinner in the sheathotomy group at 1 month (P=0.01), but not at 3, 6, and 12 months (P=0.75, P=0.81, and P=0.46, respectively). Improvement of best-corrected visual acuity at 12 months was significantly correlated with baseline best-corrected visual acuity, age, duration of symptoms, and sheathotomy (P<0.05). Conclusion Arteriovenous sheathotomy for BRVO improves best-corrected visual acuity significantly more than the natural course of the BRVO disease process.

Abstract
BACKGROUND Retinal vein occlusion is the second most common retinal vascular disorder after diabetic retinopathy and is considered to be an important cause of visual loss. In this review, our purpose is to update the literature about the treatment alternatives for branch retinal vein occlusion. METHODS Eligible papers were identified by a comprehensive literature search of PubMed, using the terms "branch retinal vein occlusion," "therapy," "intervention," "treatment," "vitrectomy," "sheathotomy," "laser," "anti-VEGF," "pegaptanib," "bevacizumab," "ranibizumab," "triamcinolone," "dexamethasone," "corticosteroids," "non-steroids," "diclofenac," "hemodilution," "fibrinolysis," "tPA," and "BRVO." Additional papers were also selected from reference lists of papers identified by the electronic database search. RESULTS Treatment modalities were analyzed. CONCLUSIONS There are several treatment modalities for branch retinal vein occlusion and specifically for its complications, such as macular edema, vitreous hemorrhage, retinal neovascularization, and retinal detachment, including anti-aggregative therapy and fibrinolysis, isovolemic hemodilution, vitrectomy with or without sheathotomy, peripheral scatter and macular grid retinal laser therapy, non-steroid agents, intravitreal steroids, and intravitreal anti-vascular endothelial growth factors (anti-VEGFs).

Abstract
Purpose. To evaluate the effects of pars plana vitrectomy (PPV) on recurrent macular edema due to branch retinal vein occlusion (BRVO) after intravitreal injections of bevacizumab (IVB). Methods. This retrospective study included 22 eyes of 22 patients who underwent single or multiple IVB injections for macular edema due to BRVO and showed a recurrence of macular edema. All patients then underwent PPV and were followed up for more than 6 months after the surgery with examinations of best corrected visual acuity (BCVA) and optical coherence tomography (OCT). OCT parameters were central macular thickness (CMT) and average retinal thickness in a 1-mm-diameter circular region at the fovea (MRT). Results. Mean BCVA, CRT, and MRT were significantly improved from the baseline after PPV. Greater improvement of BCVA, CRT, and MRT was obtained after 1 month of IVB than after 6 months of PPV. No eyes showed worsening of macular edema after the surgery. Conclusion. PPV improved BCVA and recurrent macular edema due to BRVO, but PPV that was less effective than IVB had been in the same patients. PPV may be one of the treatment options for recurrent macular edema due to BRVO after IVB.

Abstract
PURPOSE To report a case of intraretinal neovascularization in a patient with ischemic central venous occlusion. METHODS Case report. RESULTS An 18-year-old white man presented with painless decreased vision in the right eye. Slit-lamp and biomicroscopic examinations revealed 360° of neovascularization of the iris, venous tortuosity, severe retinal hemorrhages, cotton wool spots, and massive edema of the macula. CONCLUSION This is the first report of observed intraretinal neovascularization after central vein occlusion. Treatment with photocoagulation and intravitreal bevacizumab injection promoted revascularization after 1 year.

Abstract
PURPOSE To evaluate long-term efficacy of intravitreal bevacizumab (IVB) versus combined IVB and macular grid laser photocoagulation for the treatment of macular edema secondary to branch retinal vein occlusion (BRVO). METHODS In this prospective study, 18 eyes were randomized into 2 groups according to treatment: Group 1 (9 eyes) underwent IVB at baseline, at month 1, and at month 2; Group 2 (9 eyes) underwent same IVB protocol combined with macular grid laser photocoagulation. Macular edema and visual acuity represented the endpoints of the study. IVB reinjections were performed in both groups if recurrent macular edema was diagnosed. Spectral domain optical coherence tomography examination as well as visual acuity examination were performed during follow-up. Statistical evaluation was performed for a matched-pair analysis. RESULTS In Group 1, median baseline central retinal thickness (CRT) decreased from 420 µm (95% confidence interval 355.6-484.4) to 323 µm (261.44-384.56) at month 12 (p=0.06); median baseline BCVA improved from 0.7 logMAR (0.54-0.86) to 0.4 logMAR (0.29-0.51) at month 12 (p<0.01). In Group 2, baseline CRT decreased from 386 µm (353.91-418.09) to 238 µm (200.58-275.42) at month 12 (p<0.01); median BCVA improved from 0.6 logMAR (0.45-0.75) to 0.2 logMAR (0.12-0.28) at month 12 (p<0.01). A statistically significant difference (p=0.03) was found regarding the median number of injections (Group 1: 4±1.1; Group 2: 3±0.4). CONCLUSIONS Both treatment modalities appeared effective to control BRVO-induced macular edema. In the combined-treatment Group, we observed a lower number of reinjections during follow-up, suggesting the efficacy of grid laser photocoagulation to reduce the number of intravitreal injections and maintain short- and long-term results of the therapy.

Abstract
Retinal vein occlusion is a major cause of vision loss. We provide an overview of the clinical features, pathogenesis, natural history, and management of both branch retinal vein occlusion and central retinal vein occlusion. Several recent multicenter randomized clinical trials have been completed which have changed the approach to this disorder. Management of retinal vein occlusions can be directed at the underlying etiology or the resulting sequelae. Options include surgical intervention, laser photocoagulation, intravitreal pharmacotherapy, and sustained drug delivery devices.

Abstract
PURPOSE A guidelines for the management of retinal vein occlusion is presented. This is necessary because at this moment several therapeutic alternatives have been developed although their role is not yet sufficiently defined. METHODS Review of the literature for evidence published up to date. Relevant literature was identified and the level of evidence graded. Evidence was then assessed for consistency, applicability and clinical impact. The information was contrasted with those guides published in other countries. RESULTS Taking into account the different options of treatment that are currently used, several modes of action are suggested. The role of the various complementary examinations are discussed and it is recommended that criteria for the treatment are based on clinical, angiographic, and tomographic findings. CONCLUSIONS Although there is no overall consensus, these guidelines promote a good standard of clinical practise and provide an update of the management of retinal vein occlusion.

Predictive factors for functional improvement after intravitreal bevacizumab therapy for macular edema due to branch retinal vein occlusion. Graefes Arch Clin Exp Ophthalmol 2010; 249:183-92. [PMID: 21337042 PMCID: PMC3042100 DOI: 10.1007/s00417-010-1470-2] [Citation(s) in RCA: 78] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2010] [Revised: 07/15/2010] [Accepted: 07/17/2010] [Indexed: 02/02/2023] Open
Abstract
Background To identify predictive factors for improvement of visual acuity and central retinal thickness by intravitreal bevacizumab for the treatment of macular edema (ME) due to branch retinal vein occlusion (BRVO). Methods Two hundred and five eyes from 204 patients with ME secondary to BRVO were retrospectively included at six sites. All eyes received intravitreal bevacizumab therapy (1.25 mg/0.05 ml). The mean follow-up was 36.8 ± 12.7 weeks (range, 18 to 54 weeks). Measurement of ETDRS best-corrected visual acuity (BCVA, in all eyes) and optical coherence tomography (OCT, in 87% of eyes) were performed at baseline and at follow-up examinations every 12 weeks. Using fluorescein angiography, the perfusion status of the macula at baseline could be assessed in 84% of the eyes. The main outcome measures were changes in BCVA and central retinal thickness (CRT). For analysis of predictive factors, the results at 24 weeks were used. Results The median BCVA was 0.6 LogMAR at baseline and improved to 0.4 LogMAR at 24 and 48 weeks. This visual improvement was associated by a significant reduction in CRT, decreasing from a baseline of 454 μm to 267 μm and 248 μm after 24 and 48 weeks respectively. Eyes with ME and intact (perfused) or interrupted (ischemic) foveal capillary ring showed a 2-line increase of median BCVA [45 eyes (22%) and 128 eyes (62%) respectively]. However, the final median BCVA was significantly worse in eyes with ischemic ME (0.6 versus 0.3 logMAR in perfused ME). Other factors for visual improvement were absence of previous treatments of the ME, age younger than 60 years and low baseline BCVA (≥0.6 logMAR) (2, 3, and 2 median BCVA lines increase respectively). Furthermore, eyes with duration of the ME of less than 12 months responded with a 3-line increase of the median BCVA. Final CRT only showed minor differences between the subgroups. During the entire follow-up, retreatments were performed in 85% of the eyes, with a median number of injections of three (mean 3.2; range, 1 to 10) and a median time-interval between injections of 11.6 weeks (mean 14.6 weeks). Conclusions Intravitreal injection of bevacizumab resulted in a significant improvement of BCVA and reduction of ME in BRVO. Baseline BCVA, patient’s age, and duration of BRVO were found to be of prognostic relevance for visual improvement. A less favorable outcome of the bevacizumab therapy in eyes with longstanding BRVO would advocate initiation of treatment within 12 months after onset.

Abstract
PURPOSE To evaluate the perfusion effects and long-term visual outcome of pars plana vitrectomy (PPV) combined with arteriovenous sheathotomy (AVS) with or without triamcinolone for nonischaemic branch retinal vein occlusion (NI-BRVO). METHODS Prospective, interventional case series of eight patients with NI-BRVO and haemorrhagic macular oedema. Patients underwent PPV and AVS (n = 5), or PPV, AVS and intravitreal triamcinolone (IVT, n = 3). A masked grading technique assessed fundus photographs and fluorescein angiography (FFA) following surgery. Scanning laser ophthalmoscopy/optical coherence tomography (SLO/OCT) evaluated macular oedema and outer retinal architecture. Main outcomes examined included visual acuity (VA), retinal reperfusion, collateral vessel regression, vascular dilatation, cystoid macular oedema (CMO), and ocular neovascularization. RESULTS Seven of eight patients underwent uncomplicated surgery, with increased intraretinal perfusion and reduced engorgement of distal retinal veins. The mean pre-logMAR VA was 0.8 (SD 0.17) and did not improve significantly after surgery (post-logMAR 0.6, SD 0.38; p = 0.11, paired t-test). SLO/OCT showed persistent CMO in four patients, and subfoveal thinning of the photoreceptor layer. Collateral vessels disappeared at the blockage site post-AVS in 7/8 eyes, and this was associated with improved retinal perfusion. Six of eight patients developed epiretinal membrane. No patients developed ocular neovascularization. The average follow-up was 34.5 months. CONCLUSIONS PPV with AVS is a safe procedure, and adjunctive IVT had no additional effects on vascular perfusion. Successful decompressive surgery was followed by disappearance of collateral vessels at the BRVO blockage site and was a clinical marker for intravascular reperfusion. Long-term epiretinal gliosis and subfoveal photoreceptor atrophy limited functional and visual recovery.

Abstract
BACKGROUND To investigate the long-term effectiveness of intravitreal bevacizumab treatment in eyes with perfused macular edema due to branch retinal vein occlusion (BRVO). METHODS In this prospective interventional case series, 23 consecutive, previously untreated eyes with perfused macular edema were treated with intravitreal bevacizumab (1.25 mg) injections and followed for 1 year. The main outcome measures were visual acuity (VA) and central retinal thickness (CRT). In addition, VA data were adapted to the non-logarithmic VA charts used in the previously published grid laser photocoagulation BRVO Study. RESULTS The median VA gained 3.0 lines from baseline at 48 weeks. This was accompanied by a significant decrease of 39% of the median CRT. The mean number of re-injections was 1.6 during the first 6 months of follow-up and only 0.8 during the subsequent 6 months. In 65% of the cases, adapted VA data showed a gain of 1 or more lines and no eye lost more than 1 line. CONCLUSIONS Repetitive intravitreal bevacizumab injections result in a significant long-term improvement of VA and CRT. The number of re-injections necessary to maintain this effect declined over time. However, the treatment seems to be only slightly better than grid laser photocoagulation.

Abstract
Purpose To evaluate long-term visual outcome of arteriovenous adventitial sheathotomy in BRVO-induced macular edema. Methods The visual outcomes of 8 patients following vitrectomy with arteriovenous adventitial sheathotomy for BVO-induced macular edema (surgery group) were retrospectively evaluated. The three year post-operative visual acuity of the surgery group was compared with that of the conservatively managed controls. Results All patients were followed for a minimum of 36 months. Mean BCVA (logMAR) in the surgery group changed from 1.10± 0.34 to 1.19±0.70 and to 0.80±0.36 at 12 and 36 months, respectively (p=0.959 at 12 months, p=0.018 at 36 months). In the control group, visual acuity improved from 1.15±0.43 to 0.43±0.44 and to 0.43±0.39 at 12 and 36 months, respectively (p=0.015 at 12 months, at p=0.003 at 36 months). A strong trend toward better visual acuity at 12 months and final examination was observed for controls. (surgery vs. control group, p=0.052 at 12 months, p=0.066 at 36 months). Conclusions Considering the favorable natural course of BVO and the unproven effect of reperfusion on macular edema, surgical efficacy of arteriovenous adventitial sheathotomy requires further evaluation.

Abstract
PURPOSE To investigate the relationship between vitreous levels of cytokines, including interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF), and visual prognosis after pars plana vitrectomy (PPV) with arteriovenous sheathotomy in patients with branch retinal vein occlusion (BRVO) associated with macular oedema. METHODS We studied 60 patients with logMAR visual acuity (VA) scores of < 0.3 and visual impairment secondary to BRVO-associated macular oedema. All patients underwent PPV with arteriovenous sheathotomy. At the time of PPV, vitreous samples were collected from the operated eye and vitreous levels of VEGF and IL-6 were measured. Best corrected VA (BCVA) (using a logMAR chart) and foveal thickness (FT) (using optical coherence tomography) were monitored for up to 6 months after PPV. RESULTS Both BCVA and FT significantly improved after PPV. According to multiple regression analysis, both the improvement in BCVA and decrease in FT were closely related to the vitreous level of IL-6 but not to that of VEGF. The vitreous level of VEGF was strongly correlated with duration of BRVO. CONCLUSIONS Both improvement in BCVA and decrease in FT were observed after PPV in BRVO patients with macular oedema. Interestingly, these visual prognoses strongly correlate with the vitreous level of IL-6, whereas the duration of BRVO strongly correlates with the vitreous level of VEGF.

Abstract
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 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.

Abstract
PURPOSE To report the clinical experience and results of using a microsurgical technique to decompress the arteriovenous connection in complicated branch retinal vein occlusion (BRVO) combined with haemorrhage, oedema and ischaemia. METHODS We carried out a retrospective, non-randomized, interventional case study of the surgical sheathotomy decompression procedure. We enrolled 12 patients (seven women, five men; median age 64 years) with BRVO and decreased visual acuity (VA) caused by haemorrhage, oedema and ischaemia. The mean duration of thrombosis was 7 months (2-15 months). The patients were examined for pre- and postoperative best corrected VA (BCVA), intraocular pressure (IOP) and fundus photography. Ten patients were examined with fluorescein angiography and eight with ocular coherence tomography (OCT). Postoperative progression of cataract was recorded, as were other complications. The mean follow-up time was 20 months (8-39 months). RESULTS Best corrected VA had improved in nine patients, was unchanged in one patient and had deteriorated in two patients at the last follow-up. Noted complications were venous haemorrhage at surgery in five patients, retinal detachment in one patient and progression of cataract in four patients. CONCLUSIONS Microsurgical treatment with sheathotomy of BRVO is a technically feasible procedure with few complications. Postoperative increased reperfusion could explain the resolution of macular haemorrhage, oedema and ischaemia, and may improve visual function in patients with this common vascular eye disease.

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.

Abstract
PURPOSE To determine the long-term visual outcomes after vitreous surgery for macular edema with foveal hemorrhage associated with branch retinal vein occlusion (BRVO). METHODS One hundred twenty eyes of 120 patients underwent pars plana vitrectomy with or without internal limiting membrane (ILM) peeling for macular edema with foveal hemorrhage due to BRVO with a minimum 12 months of follow-up. Simultaneous cataract extraction with intraocular lens implantation was performed on 117 phakic eyes. RESULTS Follow-up after surgery ranged from 12 months to 129 months (average, 48 months). Visual acuity improved in 71% of cases at the 1-year visit. Mean visual acuity significantly increased from 0.24 (median, 0.3) before surgery to 0.57 (median, 0.7) 1 year after surgery (P < 0.0001) and 0.66 (median, 0.9) at the final visit (P < 0.0001). There was a significant difference between visual acuity at 1 year after surgery and visual acuity at the final visit (P < 0.0001). Of 120 patients, 95 (79%) had final visual acuity of > or =0.5, and 55 (46%) had final visual acuity of > or =1.0. ILM removal did not seem to have significant beneficial effects on visual outcomes in this series. No serious complications occurred during the follow-up period. CONCLUSION After vitreous surgery for macular edema with foveal hemorrhage associated with BRVO, visual acuity continued to improve beyond 1 year after surgery. A randomized, multicenter clinical trial is warranted to determine the efficacy of this procedure.

Abstract
Purpose To evaluate the efficacy of arteriovenous (AV) sheathotomy with internal limiting membrane peeling for persistent or recurrent macular edema after intravitreal triamcinolone injection and/or laser photocoagulation in branch retinal vein occlusion. Methods Twenty-two eyes with branch retinal vein occlusion (BRVO) with recurrent macular edema underwent vitrectomy with AV sheathotomy and internal limiting membrane peeling. All eyes had previous intravitreal triamcinolone injection and/or laser photocoagulation for macular edema. The best corrected visual acuity (BCVA), fluorescein angiography and optical coherence tomography (OCT) before and after surgery were compared. Results The mean preoperative BCVA (log MAR) were 0.79±0.29 and postoperative BCVA (log MAR) at 3 months was 0.57±0.33. And improvement of visual acuity ≥2 lines was observed in 10 eyes (45%). The mean preoperative fovea thickness measured by OCT was 595.22±76.83 µm (510-737 µm) and postoperative fovea thickness was 217.60±47.33 µm (164-285 µm). Conclusions Vitrectomy with AV sheathotomy can be one treatment option for the patients with recurrent macular edema in BRVO.

Abstract
Multifocal electroretinography (mfERG) is an investigation that can simultaneously measure multiple electroretinographic responses at different retinal locations by cross-correlation techniques. mfERG therefore allows topographic mapping of retinal function in the central 40-50 degrees of the retina. The strength of mfERG lies in its ability to provide objective assessment of the central retinal function at different retinal areas within a short duration of time. Since the introduction of mfERG in 1992, mfERG has been applied in a large variety of clinical settings. This article reviews the clinical applications of mfERG based on the currently available evidence. mfERG has been found to be useful in the assessment of localized retinal dysfunction caused by various acquired or hereditary retinal disorders. The use of mfERG also enabled clinicians to objectively monitor the treatment outcomes as the changes in visual functions might not be reflected by subjective methods of assessment. By changing the stimulus, recording, and analysis parameters, investigation of specific retinal electrophysiological components can be performed topographically. Further developments and consolidations of these parameters will likely broaden the use of mfERG in the clinical setting.

Abstract
PURPOSE To evaluate the long-term effect of vitrectomy with or without arteriovenous sheathotomy for macular edema secondary to branch retinal vein occlusion (BRVO). METHODS The study was a prospective, randomized, comparative, interventional case series of 36 patients (36 eyes) who underwent pars plana vitrectomy with or without arteriovenous sheathotomy for macular edema due to BRVO of <or=8 weeks' duration of symptoms. Eighteen eyes with arteriovenous sheathotomy (sheathotomy group) were compared with 18 eyes without sheathotomy (vitrectomy group). Main outcomes measures were best-corrected visual acuity and central foveal thickness as evaluated by optical coherence tomography. RESULTS Baseline demographic characteristics of the groups were similar. Postoperative follow-up period ranged from 12 months to 45 months (31 months). Median best-corrected visual acuity significantly improved from 0.4 at baseline to 1.0 at the final visit in both groups, and there was no significant difference in best-corrected visual acuity at any postoperative period between the groups. Of 16 patients with duration of symptoms of <4 weeks, those with arteriovenous sheathotomy had a tendency toward better visual outcomes than those without arteriovenous sheathotomy (P = 0.064). The central foveal thickness also significantly decreased after surgery in both groups, but the differences were not significant for the two groups at each time point. No patients had severe intraoperative and/or postoperative complications. CONCLUSIONS 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.

Abstract
PURPOSE To report the longterm follow-up of a case of branch retinal vein occlusion (BRVO) treated with vitrectomy and adventitial sheathotomy. METHODS A three-port vitrectomy was performed in a 55-year-old man with symptoms of BRVO of about 3 months' duration. After a core vitrectomy, the adventitial sheath of the affected arteriovenous crossing was dissected so that the anterior surface of the arteriole was freely exposed. RESULTS On the second postoperative day, visual acuity (VA) in the affected left eye had increased from preoperative 0.3 to 0.6. Within 6 months the fundus had almost normalized and vision improved to 1.0. Cataract surgery was performed about 2 years after the vitrectomy. At a follow-up 4 years and 11 months after the sheathotomy, VA was 1.0 and no signs of recurrence were seen. CONCLUSIONS Adventitial sheathotomy may improve vision in selected cases of BRVO. Further studies are necessary to determine the role of sheathotomy in the management of cases with BRVO.

Abstract
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 0.84+/-0.3 in the surgical group and 1.06+/-0.4 in the control group. The postoperative mean logMAR visual acuity was 0.41+/-0.2, 0.40+/-0.2, 0.40+/-0.3, and 0.36+/-0.3 at 1, 3, 6, and 9 months follow-up, respectively. In the control group the postlaser mean logMAR visual acuity was 0.92+/-0.3, 0.87+/-0.4, 0.85+/-0.3, and 0.82+/-0.3 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=0.003 and P=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.

Abstract
Application of VEGF inhibitors represents a treatment option for macular edema secondary to retinal vein occlusion that targets the disease at the causal molecular level. First reports on intravitreal injections of bevacizumab show promising morphological and functional effects and demonstrate that bevacizumab is a potent antiedematous agent in this context. A significant reduction of the central retinal thickness followed by a rapid improvement of visual acuity may be achieved within days. In a pilot study with a review period of 3 months, we found a significant improvement of one or more lines in 93% and four or more lines in 27% of eyes. This was associated with a concomitant significant reduction in central retinal thickness, which, however, was not sustained by a single injection (64% reduction after 1 month and 28% after 3 months). No relevant adverse events were noted. The duration of action after intravitreal bevacizumab administration is currently unknown. Reinjections will be necessary to maintain a lasting beneficial effect. Prospective, controlled long-term studies are mandatory to develop standardized treatment protocols that allow a safe and effective application of this off-label therapy.

Abstract
Retinal vein occlusions (RVO) are the second commonest sight threatening vascular disorder. Despite its frequency treatments for RVO are unsatisfactory and include several that have not been tested by large, well designed, prospective, randomised controlled trials. There is also the lack of long term follow up in many of the available small uncontrolled studies, and the timings of interventions are haphazard. This review aims to evaluate the current knowledge relating to the pathogenesis, suggested treatments for the different types of RVO, and their complications. Isovolaemic haemodilution is of limited benefit and should be avoided in patients with concurrent cardiovascular, renal, or pulmonary morbidity. Evidence to date does not support any therapeutic benefit from radial optic neurotomy, optic nerve decompression, or arteriovenous crossing sheathotomy on its own. Vitrectomy combined with intravenous thrombolysis may offer promise for central RVO. Similarly, vitrectomy combined with arteriovenous sheathotomy intravenous tissue plasminogen activator may offer benefits for branch RVO. RVOs occur at significantly high frequency to allow future prospective randomised controlled studies to be conducted to evaluate the role of different therapeutic modalities singly or in combination.

Abstract
PURPOSE The rationale for this pilot study was to add arterio-venous dissection (AVD) after unsuccessful medical treatment in a well-defined group of patients with branch retinal vein occlusion (BRVO). METHODS In this prospective, interventional case series 35 consecutive patients with a visual acuity (VA) of 0.4 (logMar) or worse were scheduled for surgery within the first 3 months of the onset of BRVO. The study endpoint was VA 1 year after AVD. Secondary study endpoints were: correlation of VA and successful vessel dissection; complication rate; and number of additional surgical procedures within the first year of AVD. RESULTS Preoperative VA (logMar) was 0.82+/-0.05 (range 0.2-1.6). VA 6 weeks postoperatively was 0.54+/-0.06 (range 0-1.6), 3 months postoperatively 0.61+/-0.07 (0-1.56), 6 months postoperatively 0.74+/-0.08 (range 0-2) and 12 months postoperatively 0.55+/-0.07 (range 0.1-1.5). VA improved 1 year after AVD (p=0.0004). An improvement in VA did not depend on successful separation of the artery and the vein. Four patients had a retinal detachment, 19 patients needed cataract surgery within the first year of AVD. A total of 24 additional surgical procedures were needed. CONCLUSIONS Patients with BRVO may profit from AVD compared with a historical control group. Visual improvement was found irrespective of the successful dissection of vessels. The cataract formation rate and additional surgery was a shortcoming of the AVD procedure.

Abstract
PURPOSE To compare the short-term effect of intravitreal versus retrobulbar injection of triamcinolone acetonide for the treatment of macular edema caused by branch retinal vein occlusion. DESIGN Randomized clinical trial. METHODS Sixty eyes of 60 patients who had macular edema associated with branch retinal vein occlusion were randomly assigned to receive a single intravitreal injection (4 mg) or repeated retrobulbar injections (40 mg, three times) of triamcinolone. These injections (first injection in the retrobulbar group) were given approximately 1 week after focal laser photocoagulation. Using optical coherence tomography, the central retinal (foveal) thickness and total macular volume were measured before and at 1 and 3 months after injection. Visual acuity, intraocular pressure, and the incidence of reinjection were also examined. Fifty-two patients (86.7%) completed the 3-month follow-up. RESULTS The mean foveal thickness and total macular volume decreased significantly after either intravitreal or repeated retrobulbar triamcinolone injections. Foveal thickness and macular volume were significantly less after intravitreal injection than after repeated retrobulbar injections, although there had been no significant differences at baseline. The percent reductions in foveal thickness and macular volume were also greater after intravitreal injection than after retrobulbar injections. Improvement in visual acuity was significantly better after intravitreal injection than after the retrobulbar injections. The incidence of intraocular pressure rise (to > or =20 mm Hg) was greater in the intravitreal group than in the retrobulbar group, but this was readily controlled by the use of antiglaucoma medications. After completion of the 3-month follow-up, 24 patients (46.2%) underwent reinjection. The need for reinjections was significantly greater in the retrobulbar group than in the intravitreal group (P = .0001). CONCLUSIONS A single intravitreal injection of triamcinolone is significantly more effective than are repeated retrobulbar injections in reducing macular edema associated with branch retinal vein occlusion, and leads to greater improvement in visual acuity.

Abstract
BACKGROUND Arteriovenous dissection (sheathotomy) is a new therapeutic option in patients with branch retinal vein occlusion (BRVO) and macular involvement. We present an angiographic follow-up of 22 patients who underwent arteriovenous dissection (AVD). METHODS Twenty-two patients (15 women; mean age 68.7+/-8.0 years) were examined preoperatively and 6 weeks, 3 months, 6 months, and 1 year after AVD. For assessment of retinal hemodynamics, arteriovenous passage time (AVP) of the affected and unaffected branches at first (AVPe) and at maximal (AVPmax) venous filling were measured. Changes in the foveal avascular zone (FAZ) were calculated to determine foveal structural changes. Visual acuity was assessed as functional parameter. RESULTS The early AVP (AVPe) of the affected branch increased from 4.4+/-0.8 s preoperatively to 4.9+/-0.6 s 6 weeks after surgery and decreased to 2.7+/-0.4 s 1 year after surgery (p=0.05). When compared to the unaffected control branch, AVPe was significantly increased in the affected branch preoperatively (4.5+/-0.8 s versus 1.5+/-0.2 s, p<0.01), 6 weeks (4.9+/-0.6 s versus 2.1+/-0.3 s, p<0.01), 3 months (2.7+/-0.4 s versus 1.5+/-0.2 s, p<0.01), and 6 months (3.1+/-0.4 s versus 2.2+/-0.3 s, p=0.02) after AVD. After 1 year, AVPe no longer differed between the affected and the control branch (2.7+/-0.4 s versus 2.6+/- 0.3 s). AVPmax was significantly increased in the affected branch preoperatively (11.8+/-0.8 s versus 7.7+/-1.0 s, p<0.05). The AVPmax in the affected branch with the exception of 3 months after surgery (10.2+/-1.1 s, p<0.01) was no longer elevated when compared to preoperative values. The area of the FAZ did not change significantly but showed a trend for enlargement. CONCLUSION AVD for decompression of BRVO leads to a significant decrease of AVP and may ameliorate retinal perfusion in the affected branch.

Abstract
BACKGROUND To evaluate the efficacy of intravitreal triamcinolone acetonide injection on persistent macular oedema in branch retinal vein occlusion that fails to respond to previous laser photocoagulation. MATERIAL AND METHODS A total of 19 eyes of 19 patients with persistent macular oedema due to branch retinal vein occlusion were treated with 8 mg/0.2 ml of intravitreal triamcinolone acetonide injection. The main outcome measures included best-corrected visual acuity, intraocular pressure, and macular oedema map values of Heidelberg Retinal Tomograph II (HRT II) before and after intravitreal triamcinolone injection. RESULTS The mean follow-up time was 6.2+/-1.0 months. The mean baseline best-corrected logarithm of minimal angle of resolution (LogMAR) value for visual acuities of the patients before intravitreal triamcinolone injection was 1.01+/-0.16. After treatment, it was 0.55+/-0.22 at the 1-month, 0.56+/-0.22 at 3-month, and 0.62+/-0.22 at the last visits and the differences were statistically significant when compared with baseline values (for each, P<0.001). The mean oedema map values on HRT II significantly decreased by 28.5% at 1-month, 23.8% at 3-month, and 23.8% at the last visit when compared with preinjection values (for each, P<0.001). Intraocular pressure elevation exceeding 21 mmHg was observed in 26.3% of eyes at 1-month, 15.7% at 3-month, and 5.2% at the last visit, but was controlled with topical anti-glaucomatous medications in all eyes. CONCLUSION Intravitreal triamcinolone acetonide application is a promising approach in the treatment of persistent macular oedema due to branch retinal vein occlusion non-respondent to laser photocoagulation.

Abstract
PURPOSE compare the results of vitrectomy with or without arteriovenous (AV) crossing sheathotomy for macular edema associated with branch retinal vein occlusion (BRVO). DESIGN Interventional case series. METHODS A retrospective study of 36 eyes with BRVO-associated macular edema. Twenty eyes underwent AV sheathotomy (AS group), and 16 eyes underwent posterior vitreous detachment (PVD group). Best-corrected visual acuity (BCVA), fluorescein angiography (FA), and optical coherence tomography to determine foveal thickness were conducted preoperatively and at 12 months postoperatively. RESULTS The mean postoperative BCVAs were significantly better in both the AS and the PVD group (P = .008 and P = .001, respectively). Foveal thickness decreased significantly 1 month after surgery in both groups (P = .002 and P = .007) and continued to decrease up to 12 months. The postoperative mean BCVA and improvement of BCVA and foveal thickness were not significantly different for the two groups at any postoperative period. Postoperative FA showed reperfusion of the occluded vein in 10 eyes in the AS group and 2 eyes in the PVD group, and formation of shunt vessels at the AV crossing site or around the macular region in all of the other eyes of both groups. CONCLUSIONS Both AV sheathotomy and simple PVD significantly reduced macular edema associated with BRVO. However, there was no significant difference in the improvement of macular function following either procedure. Postoperative improvement of retinal circulation by either reperfusion of the occluded vein or collateral vessel formation was found. This accounted for functional and morphologic improvements.
