AIM:To investigate the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system before and after laser peripheral iridectomy(LPI)in primary angle-closure suspetive(PACS).METHODS: Sixty eyes of 33 PACS patients were enrolled in this study. Pentacam examination was performed before and 1d after LPI to measure the central anterior chamber depth(CACD), the peripheral anterior chamber depth(PACD), the anterior chamber volume(ACV)and the peripheral anterior chamber angle(ACA). Statistical analysis used paired t test. RESULTS: There was no statistical significance on the changes of ACD. PACD and ACV increased significantly between before and 1d after LPI. ACA was widened from(22.26°±5.18°)to(26.42°±5.20°), which were increased significantly between before and 1d after LPI.CONCLUSION: LPI can deepen the PACD and increase the ACV in PACS. PACD and ACV are the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system.
