Br J Ophthalmol. Janet L. Alexander. Indian J Ophthalmol. Nine papers were identified that described the use of UBM in ocular trauma. Only 59% of papers explicitly stated the UBM platform and probe frequency used. Mungan N, Nischal KK, Hon E, MacKeen L, Balfe JW, Levin AV. Correspondence to Outcomes were subcategorized by type of study design, UBM platform used, probe frequency used, clinical application including broad disease category (i.e., glaucoma, trauma, uveitis) and specific disease category (i.e., glaucoma following congenital cataract surgery, traumatic cyclodialysis, and toxocara uveitis), anatomy of interest, and outcomes including the quantitative and qualitative utility of UBM reported. Interestingly, changes of ET have been shown even in subclinical disease and could be a sensitive marker in early and form fruste keratoconus. In order to fully appreciate the quantitative features of UBM imaging in pediatric disease, a sophisticated understanding of normal structural anatomy is essential. Ultrasound devices, which generate high-frequency sound waves, are best known for their imaging powers. https://doi.org/10.1136/bjophthalmol-2013-303662. Studies were eligible if they met the following criteria: (1) use of cohort, case-control, or cross-sectional study design; (2) study population included enrollment of at least four pediatric subjects age 018 years old (inclusion of adults was not grounds for exclusion as long as the minimum pediatric enrollment was met); (3) use of UBM was explicitly stated and results of UBM were reported. 2006;10:721.
