WebMar 25, 2024 · A thin or thick cornea can underestimate or overestimate IOP.[10 11] Accordingly, there is a need to adjust IOP values taking CCT into consideration, for it may change the treatment decisions and affect patient outcomes.[12 13] Several nomograms have been developed for adjusting GAT readings for varying CCT; however, these … WebMar 1, 2012 · Results. Average PDCT IOP values were higher than GAT, IOPg, IOPcc, and CCT-adjusted IOP. The GAT IOP readings demonstrated poor agreement with PDCT IOP (95% limits of agreement, ± 4.7 mmHg); however, IOPg, IOPcc, and adjustment of GAT IOP with CCT-based formulae resulted in even poorer agreement (range of 95% limits of …
WebFor more accurate measurement of the IOP, CCT is an important factor that has to be taken into consideration and adjustments in the measured IOP are needed for the clinical management of glaucoma ... WebAssuming a normal CCT of 520 μm, an IOP correction for every 10 μm change in corneal thickness is recommended. But in the Ehlers paper, there are some confusing arguments. Ehlers et al2 describe a very good correlation between direct and intracameral IOP measurement (correlation coefficient approximated 1).
