Preplaced landmarks yielded good IOR and IOA in quantitative assessment of AS structures that were NTD and non-CB-related or less removed from the reference. CB-related NTD measurements varied greatly in IOR and IOA, indicating protocol modifications or CB qualitative assessments needed to improve accuracy. Variability in TD measurements increased the further removed from the reference, which supports implementation of a reliable reference landmark to minimize variation.

Purpose: To quantitatively describe the structural corneal changes from infancy to early adulthood using ultrasound biomicroscopy. Methods: In this prospective study, 168 ultrasound biomicroscopy images were obtained from 24 healthy eyes of 24 patients who consented and enrolled in the Pediatric Anterior Segment Imaging Innovation Study. Their ages ranged from birth to 26 years. An established ultrasound biomicroscopy imaging protocol including seven views of one eye per patient were obtained and measured using ImageJ software (National Institutes of Health). Twelve corneal structural parameters were measured. Means were compared between younger and older groups. Results: Among the 12 measured structures, 5 demonstrated statistically significant differences ( P < .05) between patients younger than 1 year and patients older than 1 year. The mean values for corneal cross-sectional width and length, central corneal thickness, and radii of curvature (anterior and posterior) were significantly different in patients younger than 1 year. Curvature and limbus-to-limbus dimensions changed more dramatically than thickness and tissue density. When comparing the youngest to oldest subgroups, anterior curvature flattened (6.14 to 7.55 radius), posterior curvature flattened (5.53 to 6.72 radius), angle-to-angle distance increased (8.93 to 11.40 mm), and endothelial cross-sectional distance increased (10.63 to 13.61 mm). Conclusions: Pediatric corneal structures change with age. The most significant changes occur in the first months of life, with additional changes later in childhood. This study further demonstrates the importance of age in pediatric corneal imaging analysis. [ J Pediatr Ophthalmol Strabismus. 2020;57(4):238–245.]

In the evaluation of patients with inflammatory bowel disease, assessment of extraintestinal manifestations of disease is integral to clinical management. The patient described in this case is a 24-year-old woman with a history of inflammatory colonic Crohn's disease (CD) who presented to the hospital with one week of vaginal pain and swelling. Initial assessment focused on infectious etiologies, though final diagnosis of vulvar CD was made on biopsy. Clinical course and treatment of vulvar CD are poorly defined in existing literature. This case highlights the multidisciplinary management of inflammatory bowel disease patients and successful treatment of a rare extraintestinal manifestation with anti-interleukin 12/23 therapy.
