Abstract Glaucoma is a disease of agroup of neuropathic disorders that affect optic nerve head and may lead to damage of retinal nerve fiber layer(RNL) this damage due to elevated IOP in most types of glaucoma and with within normal IOP which is (11-20)mmhg with low tension glaucoma so IOP is amean factor in Glaucoma diagnosis ,management and rate of progression on other hand there is the cornea which is the transparent part of the outer eye coat ,corneal thickness has wide range of normal(500-600)micrometer but the most accurate 555 according to Benedik Goldmann who designed aplanation tonometry Measurement of IOP is by using slit lamp aplanation tonometry and measurement of corneal thickness is done with pachymetry and anterior segment optical coherence tomography IOP and corneal thickness both affect each other so in our study we are trying to prove effect of IOP on corneal thickness by measuring IOP and corneal thickness in 30 Glaucoma cases on treatment for three visits three months apart After this it was found that 9 patients which has POAG there was an increase in their corneal thickness and 6 patients which has low tension Glaucoma there was affine change in their corneal thickness but to aless extent than with POAG. |
