In patients with DME or macular edema due to RVO, the number of HRDs on SD-OCT may be a predictive indicator of the response to IVB injection or dexamethasone implant. In bevacizumab responders, the number of HRDs on SD-OCT was small. In contrast, more HRDs, which might reflect increased inflammation in the retina, were observed in dexamethasone responders. Therefore, dexamethasone implants might be more effective in DME or RVO eyes with multiple HRDs and OPL disruption on SD-OCT.
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.
