“…The bifurcation of the superior and inferior central retinal veins occurs anterior to the lamina cribrosa; so the entire retina could be drained with a single inferior anastomosis. 22 Although our surgical success (defined as patent/induced shunts) was 47% and less than that of Peyman's report (62.5%), 12 the clinical success (defined as uneventful postoperative course and development of at least one inferiorly placed active shunt) was 90% (Koizumi et al reported a clinical success of 70% for surgical shunt induction in a group of intermediate CRVO subjects 10 ).…”

“…9 Vitrectomy combined with intentional interruption of retinal vein in a group of intermediate CRVO cases also reported by Koizumi et al in 2002. 10 In 1999, Fekrat et al performed venipuncture to induce the venous shunt in a case of ischaemic CRVO. 11 In the same year, Peyman et al reported surgical chorioretinal venous anastomosis for the ischaemic subtype in which, following standard vitrectomy, they inserted Mersilene suture beneath the retina, adjacent to the major retinal veins.…”

Aim: To evaluate the safety and efficacy of surgical induction of chorioretinal venous anastomosis in the management of ischaemic central retinal vein occlusion (CRVO). Methods: In a comparative clinical trial, 28 patients with ischaemic CRVO were included, of whom 18 who declined surgery were considered as controls. The 10 surgical cases underwent standard vitrectomy with incisions into the choroids adjacent to the partially cut major retinal veins. Mersilene suture insertion was done to induce chorioretinal venous shunt. Mild endolaser was applied. Patients were followed up for 6-18 (mean 10) months. Results: Clinical success in shunt development was 90%. Surgical cases had a significantly better visual acuity improvement compared with controls (mean difference: 1.5 logMAR, p = 0.001) with 80% of them showing improvement (compared with 28% of the controls, p = 0.016). Neovascularisation developed in 39% of the control group compared with 0% of the surgical cases (p = 0.03). In multivariate analysis, surgery remained the sole significant predictor of visual improvement. There were three re-operations for vitreous cavity haemorrhage, cataract, and retinal detachment. Conclusions: Surgical induction of chorioretinal venous anastomosis may result in visual acuity improvement and prevent neovascularisation in ischaemic CRVO. Randomised studies are needed to compare the current study modality with the natural course of CRVO and emerging procedures, such as optic neurotomy, in the management of ischaemic CRVO. C entral retinal vein occlusion (CRVO) is a relatively common cause of visual loss; after diabetic retinopathy, it is the most frequent vascular accident.

“…(2005) also experienced complications with this procedure in 30% of patients, including retinal detachment, vitreous haemorrhage and cataract. Koizumi et al. (2002) achieved successful chorioretinal venous anastomosis in 71% of seven consecutive patients with CRVO by cutting off the affected retinal vein by means of vitrectomy and making a small incision at both sides of the vein interruption through the full thickness of the retina, retinal pigment epithelium and Bruch’s membrane.…”

ABSTRACT.The treatment of central retinal vein occlusion (CRVO) is still a subject of debate. Medical therapy efforts, as well as retinal laser photocoagulation, have mostly dealt with management of the sequelae of CRVO, and have shown limited success in improving visual acuity. The unsatisfactory results of such therapeutic efforts led to the development of new treatment strategies focused on the surgical treatment of the occluded retinal vein. The purpose of this review is to summarize the outcomes of commonly reported surgical treatment strategies and to review different opinions on the various surgical approaches to the treatment of CRVO.
