Purpose The aim of this study is to quantify changes in anterior segment morphology by the use of ultrasound biomicroscopy (UBM) after Nd:YAG laser iridotomy in primary angle closure (PAC) and PAC glaucoma (PACG) in European eyes. Methods A total of 35 eyes of 28 consecutive patients presenting with PAC or PACG were examined by UBM at presentation, and 1 week after Nd:YAG laser peripheral iridotomy (LPI). Mean age of patients was 63.5 ± 14.4 (SD) years. Seventeen patients were females (60%). The trabecular-iris angle (TIA) was measured in the superior, nasal, inferior, and temporal quadrants. Baseline measurements were made under light and dark conditions. Main outcome measure UBM measurements of the trabecular-iris angle (TIA) and the angle opening distance (AOD). Design Consecutive observational case series. Results All measurements were made in four quadrants. Before LPI, mean superior TIA was 3.59 ± 4.5° (mean ± SD), nasal TIA was 6.37 ± 4.9°, inferior TIA was 9.33 ± 7.6°, and temporal TIA was 8.65 ± 7.3° in light conditions. After LPI, these values increased, respectively, to 12.58 ± 6.9° (P<0.05), 15.40 ± 6.8° (P<0.05), 16.37 ± 7,4° (P<0.05), and 15.95 ± 11.3° (P<0.05), showing a significant widening of the angle in all four quadrants. Superior AOD increased from 0.060 ± 0.07 to 0.107 ± 0.07 mm (P=0.09). No serious LPI-related complications were encountered. Conclusions Dimensions of the anterior chamber angle can be significantly influenced by Nd:YAG laser iridotomy in narrow angle European eyes. UBM examination is a viable tool for the quantitative evaluation of the anterior chamber angle before and after laser iridotomy.
