Comparison between B scan ultrasonography, immersion UBM and contact UBM techniques in evaluation of the lens area

Abstract

Purpose: The aim of our work is to compare between B Scan Ultrasonography, Immersion UBM and Contact UBM Techniques In evaluation of the Lens Area. Methods: A prospective observational case series study was performed on thirty eyes for patients suffering from lens pathology examined by B Scan Ultrasonography, Immersion UBM and Contact UBM at the Ophthalmology Department in Tanta University Hospitals from January 2021 till June 2021 and performed by Sonomed Escalon ophthalmic ultrasound Vupad, U.S.A.Results: The mean age was 59.67±5.80 with peak incidence between the ages of 60 to 69 years. 43.3% cases were males and 56.7% cases were females. The mean value of the depth of the anterior chamber by immersion UBM and contact UBM was 2.565±0.292 mm (range from 2.11 mm to 3.04 mm) and 2.183±0.457 mm (range from 1.52 mm to 2.99 mm) respectively and underestimated by contact UBM with statistically significant difference between the values that measured by the two methods (p value
