PURPOSE:: To investigate the changes of anterior segment morphology in patients with narrow angles using a rotating Scheimpflug camera before and after laser peripheral iridotomy (LPI). MATERIALS AND METHODS:: Forty-six eyes of 46 patients classified as primary angle closure suspect, primary angle closure, primary angle closure glaucoma, acute angle closure glaucoma, fellow eyes of acute angle closure glaucoma, and iris plateau configuration were enrolled in this prospective interventional case series. Anterior chamber volume (ACV), anterior chamber depth (ACD), and anterior chamber angle (ACA) were evaluated with an Scheimpflug camera, before and after LPI. RESULTS:: After LPI, the average anterior chamber depth increased from 1.88±0.36 to 1.93±0.32 mm (P=0.49). The mean ACV increased from 74.6±25 to 89.4±21.1 mm (P=0.003). The average ACA increased from 21.1±4.8 to 23.4±3.8 degrees (P=0.01). Eyes with synechial angle closure (primary angle closure and primary angle closure glaucoma) demonstrated a significantly smaller change in ACV compared with eyes with appositional angle closure (primary angle closure suspect). CONCLUSIONS:: ACV and ACA determined by Scheimpflug technology increase to a statistically significant degree and this change appears to be more pronounced in cases of appositional angle closure.
