Halkiadakis I, Vernikou A, Tzimis V, et al. - In this cross-sectional study, researchers assessed corneal epithelial thickness (CET) parameters by means of anterior segment optical coherence tomography in glaucomatous patients undergoing medical treatment and compared them with CET parameters of controls. The sample consisted of 62 patients with primary open-angle or pseudoexfoliative glaucoma (study group; mean age 68 ± 11.9 years) and 62 age-matched controls (mean age 65.5 ± 8.5). Data reported that central corneal thickness was 537.6 ± 33.3 in the glaucoma group and 550.8 ± 33.7 in the control group, respectively. Glaucoma-treated patients have uniformly decreased corneal epithelial thickness.
