P292: Assessment of interpupillary distance in a racially/ethnically diverse pediatric sample from electronic health record data

Anthropometric measurements are an important part of the dysmorphology evaluation routinely performed by clinical geneticists. Relating a patient’s ocular measurements to the general population allows clinicians to identify hyper- or hypotelorism on physical exam, aiding in diagnosis and management. Unfortunately, existing normal value charts for inner canthal distance, outer canthal distance, and interpupillary distance are suboptimal due to a lack of computability, a lack of racial and ethnic diversity, a lack of charts that extend into adulthood, and systematic errors.
