Experimental Protocol Designed to Employ Nd:YAG Laser Surgery for Anterior Chamber Glaucoma Detection via UBM

The study developed an experimental protocol using Nd:YAG laser surgery and ultrasound biomicroscopy (UBM) to detect anterior chamber glaucoma (ACG) by measuring anterior chamber parameters in five directions. Conducted on 60 patients aged 20-54, it highlighted UBM's advantages over other imaging techniques, providing high-resolution images for detailed analysis. The research found significant differences in anterior chamber angle (ACA) and angle opening distance (AOD) across directions, with the temporal direction being the widest and the upside the narrowest. These findings were crucial for planning laser surgery, suggesting the temporal direction as optimal to prevent pupil block and photic phenomena. The study emphasized the importance of direction-specific measurements in guiding surgical decisions.
