Chorioretinal anastamosis

Overall, chorioretinal anastamosis is a procedure that may be best performed for nonischemic CRVO as the major complication of pre- and subretinal fibrosis is more likely in ischemic CRVO. These uncontrolled trials have not proven that this procedure is superior in outcome to the natural history of non-ischemic CRVO. Additionally, the risks as demonstrated in these trials are significant. As a result, this procedure has not gained wide acceptance.
