AIM: To investigate the biologic structures of primary angle closure glaucoma (PACG) and to discuss the relation of the structure and shallow anterior chamber after trabeculectomy. METHODS: A total of 102 eyes of PACG and 20 normal eyes were measured with A-mode ultrasonic scanning machine. Trabeculectomy was performed on all eyes of PACG. Intraocular pressure (IOP), anterior chamber and bulb were examined after surgery. RESULTS: There were significant differences between the two groups in anterior chamber depth (ACD), relative location of lens (RLL), lens thickness (LT) and axial length (AXL). There are also differences between 9 glaucoma eyes and other eyes of PACG group. Postoperative IOP of all glaucoma were below 2.0kPa, average IOP being 1.12 ± 0.23kPa. Shallow anterior chambers were observed in 41 eyes. Lenses were removed in 9 shallow anterior chamber eyes of extreme abnormal structure. CONCLUSION: Measurement of biologic structures of PACG, including ACD, RLL, LT and AXL, is helpful for choosing proper operation and avoiding postoperative shallow anterior chamber. LA: Chinese
