Central Corneal Endothelial Cell Density After Argon Laser Trabeculoplasty

We report our experience using specular microscopy to perform endothelial cell counts in a series of 16 patients with bilateral, uncontrolled, primary openangle glaucoma undergoing argon laser trabeculoplasty (ALT). Trabeculoplasty was performed in 20 eyes of these 16 patients. Untreated fellow eyes in 11 patients were used as controls for this series. Endothelial specular microphotographs and pachymetry were done using a Pocklington specular microscope (Keeler-Konan) before ALT and again approximately one and four months later. The endothelial cell densities were normal in all of the affected eyes before treatment and in the control eyes. No statistically significant differences between the pretreatment and posttreatment cell densities and pachymetry values relative to the controls were observed during the course of this study.
