Purpose: Our purpose was to investigate the laser peripheral iridotomy (LPI) induced changes in corneal densitometry in acute primary angle closure glaucoma (PACG) cases during the post-laser 1 month period. Material and methods: This prospective study included 21 eyes of 21 cases with first acute attack of PACG. All the eyes underwent LPI with neodymium: yttrium-aluminum-garnet (Nd: YAG) laser after the intraocular pressure (IOP) decreased to normal levels with maximal systemic and topical anti-glaucoma treatment and complete regression of clinically significant corneal edema. Central corneal thickness (CCT) and corneal density values were measured by densitometry software of Pentacam HR-Scheimpflug corneal topography over a 12-mm diameter of the cornea just before LPI and at the first week and the first month after LPI. Kolmogorov smirnov and paired-t tests were used for statistical analysis.
