Abstract:
?AlM:To investigate the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system before and after laser peripheral iridectomy (LPl) 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 LPl 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 LPl. ACA was widened from (22. 26o±5. 18o) to (26. 42o±5. 20o), which were increased significantly between before and 1d after LPl.
?CONCLUSlON: LPl 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.
