Abstract
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 hystory of trauma, corneal surgery and were not patients with contacts lens use.
Patients with pseudoexfoliative glaucoma and also patients with open angle glaucoma had signifficantly lower values of
cenral 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.
