This large series of posterior segment IOFBs shows that recent advances in surgical techniques are associated with a significant improvement in prognosis.
Chronic ischemia of the primate anterior optic nerve induced with endothelin-1 infusion resulted in diffuse loss of axons without a change in the intraocular pressure.
Comparison of these results with those of a previous audit carried out at this hospital 23 years ago suggests little improvement in the success rate of primary surgery (75% vs 80%). The improvement in final retinal reattachment has been rather greater (from 88% to 97%). The major impact of recent technical advances in retinal reattachment surgery has been on the success rate of reoperations after failed primary surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
