All patients underwent below mentioned clinical examination at the same visit: BCVA, Slit lamp exam, Applanation tonometry, Gonioscopy, Dilated fundus examination and stereoscopic examination of the optic disc and nerve fiber layer, white on white visual fields- 24-2 programme, Pachymetry: Sample was divided into three groups according to-<strong>1- Mean deviation (MD) values:</strong> <em><span style="text-decoration: underline;">Mild damage group</span></em>- MD better than -6db, <em><span style="text-decoration: underline;">Moderate damage group-</span></em> MD between -6db and -12db, <em><span style="text-decoration: underline;">Severe damage group-</span></em> MD worse than -12db.:<strong>&</strong> <strong>2- Central corneal thickness: </strong><em><span style="text-decoration: underline;">Thinner corneas-</span></em> ≤520µ, <em><span style="text-decoration: underline;">Adequate corneas-</span></em> >520µ & ≤555µ, <em><span style="text-decoration: underline;">Thicker corneas- </span></em>>555µ. <strong>One-way analysis of variance</strong>, test was performed to find out the correlation of severity of primary open angle glaucoma with central corneal thickness. <strong>2 tailed Pearson correlation test </strong>was used<strong> </strong>to find out the existence of any equation between Central Corneal thickness and worsening of Mean deviation values.</p> <p style="padding-top: 8px;"><strong>RESULTS:</strong><span style="font-family: Calibri; color: yellow;"> </span>Significant association of severe disease with thin cornea (P= 0.021), A significant finding of Central CornealThickening as MD worsens was found in mild damage group only (<em>Pearson correlation factor= -0.250, P= 0.024</em>), All thin corneas are not associated with severe disease, None of the severity indicators of the disease correlated with decreasing corneal thickness, Sudden dip in CCT and worsening of the disease in 7th decade.</p> <p style="padding-top: 8px;"><strong>CONCLUSION: </strong>Corneal thickness in glaucomatous patients could be a kinetic process,increasing CCT means progressive disease and pressures not adequately controlled and thinning means the tisue has given up under the stress of increased pressures and disease will progreess ferrociouly thus needing tight control on IOP in the form of  surgical intervention. hence periodic CCT measurements are mandatory</p> <div class="border-top py-2"><b>Posted by: </b>Pankhuri Johari, pivate practitioner, sri ram janaki netralya, India (<span class="f-sm">01-Nov-2011</span>)</div> </div>
