BACKGROUND AND OBJECTIVE: This study aimed to identify the degree of concordance between fluorescein angiograms (FA) and fundus photographs (FP) in assessing the severity and potential need for treatment in infants 45 weeks or older postmenstrual age (PMA) with type 2 or less retinopathy of prematurity (ROP). PATIENTS AND METHODS: An observational retrospective case series performed at Associated Retinal Consultants, William Beaumont Hospital in Royal Oak, Michigan. All infants born between 2006 and 2016 with stage 1 to 3 ROP that did not meet type 1 ROP criteria (type 2 or less) who received ablative laser therapy during or after age 45 weeks PMA. Pretreatment FP and FA images were randomized and sent to nine expert retina specialist graders to assess severity and inter-grader variability. RESULTS: A total of 10 babies (19 eyes) were enrolled in this study, and 53 FAs and 27 FPs of these 19 eyes were selected to be interpreted by the nine graders. The number of eyes deemed to be abnormal and warranted for treatment was higher with FA, whereas more eyes were deemed "normal" with FP. CONCLUSION: Although still controversial, knowledge of these findings may encourage retina specialists to closely examine infants with mild ROP older than age 45 weeks PMA and consider ablative laser therapy under certain conditions (even if not meeting type 1 Early Treatment for ROP criteria).
