CFT is a sensitive and early predictor of VA deterioration. Four letters of acute VA loss seems to be a critical limit. VA loss of ≥ 4 letters appears to be associated with incomplete recovery. Eyes with <1 line of gain at the end of the loading phase should be considered for continuation of treatment at months 3 and 4. According to our calculations an average number of 8.4 injections/eye seems to be necessary to maintain stabilization of vision in the first year of treatment.
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.
