چکیده

Iatrogenic retinal vein to choroidal vein anastomoses were created using laser photocoagulation in six of seven dog eyes in which a partial branch retinal vein occlusion had previously been created photochemically. A similar attempt to create an anastomosis was made in six control eyes in which no branch vein occlusion was present. In the eyes in which a branch retinal vein had been created, a venous chorioretinal anastomosis appeared to be present by 3 to 6 weeks. In three control eyes similar venous anastomosis was created; however this took 6 to 8 weeks to develop and was of much smaller calibre than the one that developed in the presence of a partial branch retinal vein occlusion. No adverse complications were noted in the period of the study (3 months). This study demonstrates that chorioretinal venous anastomoses can be created and may be of use in the treatment of partial retinal vein occlusions that show signs of progression.

EXTENDED REPORT Surgical induction of chorioretinal venous anastomosis in ischaemic central retinal vein occlusion: a non-randomised controlled clinical trial

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 ch...

tinct zones, each with different venous drainage. Between these 2 zones, a watershed developed. After the 2 chorioretinal anastomoses matured, blood flow through the venous tributary that bridged the watershed zone— the tributary connecting the inferotemporal branch retinal vein to the central retinal vein—was very slow (Figure 2B). The slow blood flow made that blood vessel susceptible to veno...

Intravitreous bevacizumab in the treatment of macular edema from branch retinal vein occlusion and hemisphere retinal vein occlusion (an AOS thesis).

PURPOSE To compare intravitreous bevacizumab to other current treatments of branch retinal vein occlusion (BRVO) and hemisphere retinal vein occlusion (HRVO) with consideration to visual outcome, cost, convenience, and risk of treatment. METHODS This is a retrospective chart review from a large referral retina practice. The data comprise 56 patients with BRVO and HRVO treated by intravitreous...
