Application of ultrasound biomicroscopy in ultrasound cycloplasty
Objective To investigate the application of ultrasound biomicroscopy in observing the morphologi-cal changes of the ciliary body before and after ultrasound cycloplasty.Methods A retrospective observation approach was employed,and included in the study were 23 glaucoma patients who had undergone ultrasound ciliary process ablation treatment at The Second Hospital of Lanzhou University from August 2020 to July 2021.Ultrasound biomicroscopy was performed preoperatively and postoperatively at one week,one month,and three months after ultrasound cycloplasty.The morphological differences in the ciliary body and ciliary processes at different time points were recorded and analyzed.Results In the 23 cases,the average preopera-tive intraocular pressure was(44.83±6.25)mmHg,with a mean intraocular pressure reduction of 38.9%at 1 week postoperatively,43.2%at 1 month and 43.8%at 3 months,all showing statistically significant differ-ences(P<0.001).Ultrasound biomicroscopy revealed changes in the thickness and number of ciliary processes in glaucoma patients before and after ultrasound cycloplasty surgery at different time points.Compared to pre-operative values,the ciliary process thickness decreased and ciliary process number decreased at different postoperative time points,with statistically significant differences(P<0.05).Conclusion ultrasound biomi-croscopy allows accurate observation and quantitative analysis of the morphological changes in the ciliary body.It demonstrates a clear effect in observing the morphological changes during ultrasound cycloplasty,providing valuable guidance for setting treatment parameters during ultrasound cycloplasty and predicting postoperative therapeutic efficacy in clinical practice.
