A comparative evaluation of cataract classifications based on shear-wave elastography and B-mode ultrasound findings
In this study, a comparison is made of the findings of B-mode ultrasound and ultrasound elastography with the Lens Opacities Classification (LOCS) grade in patients with senile cataracts. A total of 74 patients with cataracts and 32 age-matched healthy volunteers as the control group were evaluated in the departments of ophthalmology and radiology between 2016 and 2017. In the patient group, cataracts were graded according to LOCS, and B-mode sonographic appearance and elasticity measurements were recorded, after which the cataract grade and sonoelastography/B-mode ultrasound findings were compared using statistical methods. Among the 74 patients with cataracts, 38 were females (51.4%) and 36 were males (48.6%), and the mean age was 62.05 ± 7.95 (43–78) years. A Chi-square test revealed a significant relationship between ultrasound echogenicity of cataract and grade of cataract (p < 0.005). The ultrasound elastography revealed a mean shear-wave velocity of 2.90 m/s ± 0.371 (2.13–3.53) among patients with grade 3 cataracts, 3.1 m/s ± 0.45 (2.26–3.98) among patients with grade 4, 3 m/s ± 0.58 (2.35–4.60) among patients with grade 5 and 3 m/s ± 0.528 (2.31–4.50) among patients with grade 6 cataracts, and 3 m/s ± 0.258 (2.36–3.58) among the normal subjects. No statistically significant difference was noted in the analysis of variance (p > 0.005). While cataract grade and B mode echogenicity were directly proportional, there was no significant difference in lens elasticity.
