The authors describe a modified immersion B-scan ultrasonography that includes a standard B scan probe of 10MHz, a surgical glove and sterile saline to fill a finger of the surgical glove – tied off to create the desired immersion standoff and placed on the ocular surface and then aqueous gel applied between the glove and B scan probe. They compared results with this method to standard anterior segment imaging using ultrasound biomicroscopy (UBM) of 50MHz in two cases. For both, they were able to display the anterior segment anatomy with identification of cornea, iris, lens and ciliary body along with a view of posterior segment anatomy. They recommend future comparisons with larger patient numbers as there is potential for this to be a cheaper alternative and useful therefore in lower resource and non-specialist hospitals / clinics with potential expansion of use in low- and middle-income countries.
