Corneal thickness in pseudoexfoliative glaucoma.
Measurements of central cornea thickness (CCT) have a very important value in glaucoma patients; if the central cornea is thinner than it suggests, then the intraocular pressure is falsely low. This study compares the central cornea thickness between patients with pseudoexfoliative glaucoma, open angle glaucoma, angle closure glaucoma and control group. This study included 34 patients with pseudoexfoliative glaucoma, 31 patient with open angle laucoma, 28 patients with angle closure laucoma and 36 normal subjects in a control group. Patients in all groups and also normal subjects in control group had no other corneal disorders, no history of trauma, corneal surgery and were not patients with contacts lens use. Patients with pseudoexfoliative glaucoma and also patients with open angle glaucoma had significantly lower values of central cornea thickness compared with normal subjects in control group. Tomey EM 3000 is a non contact specular microscope which was used to measure central corneal thickness in this study. Pachymetry is an important method for diagnoses of glaucoma and for examination of the intraocular pressure in glaucoma patients, because values of the central corneal thickness affect the exact intraocular pressure readings.
