WebThe association between CCT and IOP for glaucoma subjects was weak, with an indication of an increase of 0.35 mmHg in intraocular pressure for every 10 ìm corneal thinning. The central corneal thickness is a better predictor than intraocular pressure in identifying those at higher risk of developing primary open-angle glaucoma when combined ... WebThis calculator is based on a meta-analysis. For every 20 micron change in Central Corneal Thickness (CCT), Intraocular Ocular Pressure (IOP) will change 1 millimeter. For every 50 micron change in CCT, IOP will …
