Exudate was the least frequently recorded OCT marker of lesion activity, accounting for fewer than 2% of both injection and non-injection visits. VA loss of >5 ETDRS letters since best VA was most frequent at injection visits (panel a). The occurence of combinations of these features observed at injection visits is presented in panel b. The asterisk symbol indicates the VA loss of >5 ETDRS letters since best VA.
