BACKGROUND AND OBJECTIVE: Retinal nonperfusion is closely associated with vision-threatening complications such as neovascularization and macular @entity4 . The purpose of this study is to investigate the reliability of a calculated @entity63 index (ISI) by means of intergrader and intragrader agreement on ultrawide-field @entity941 angiography (UWFFA) in common @entity989 . @entity1 AND METHODS: Eight trained graders evaluated 15 UWFFA images provided digitally and re-graded on a different day. They included @entity735 with @entity6 ( @entity6 ), five with branch @entity2994 (BRVO), and five with central @entity2994 (CRVO). To assess intergrader and intragrader agreement and variability among different diseases, the replicate inter- and intragrader standard deviations (SDs) and coefficients of variation (CVs) were calculated. RESULTS: Mean ISI was 46% for images of @entity6 , 26% for images of BRVO, and 61.3% for images of CRVO. Combined intragrader and intergrader replicate SDs were 17.8% for @entity6 , 3.8% for BRVO and 13.0% for CRVO. Combined intragrader and intergrader replicate coefficients of variation were 38.6% (percent of mean ISI) for @entity6 , 14.7% for BRVO, and 21.2% for CRVO. CONCLUSION: Intergrader and intragrader variability was high when assessing @entity6 . This may be due to the chronic nature of @entity6 progression, which can lead to patchy areas of @entity63 . Intergrader and intragrader variability was better for CRVO and best for BRVO. This may be due to the acute or subacute nature of @entity2994 .
