Agreement between pairs of OCT scans obtained on the Stratus™ OCT and Cirrus™ HD-OCT based on consensus grades (A) Percentage of OCT scan-pairs whose consensus grades are in agreement, with respect to intraretinal fluid (IRF), subretinal fluid (SRF), and on the decision to treat (based on the presence of exudative activity, as evidenced by the presence of either IRF or SRF). (B) Distribution of OCT scan-pairs whose consensus grades were discordant. The number of discordant pairs favoring the presence of intraretinal fluid (IRF), subretinal fluid (SRF), and on the decision to treat is shown in each column. (C) Comparison of OCT scan-pairs in the consensus detection of intraretinal fluid (IRF), subretinal fluid (SRF), or either (resulting in a decision to treat).
