IOP Correction for Central Corneal Thickness (CCT) - Eyedocs
Manufacturers of devices that measure corneal thickness (such as the corneal pachymeter) often supply clinicians with tables, which help to convert corneal thickness measurements into an "adjustment factor." This adjustment factor is applied to the measured IOP, in order to determine more closely the "true" IOP for a given eye.
IOP Adjustment - ODReference
Techniques such as pachymetry provide precise corneal thickness measurements. Pachymetry is a non-invasive procedure that uses ultrasound or optical devices to measure the central corneal thickness (CCT). This information is crucial for adjusting IOP readings accurately.
Central corneal thickness can be easily measured using a handheld ultrasound pachymeter. This article provides an overview of the methods of corneal pachymetry and the interpretation of the results. Daniel has over 20 years’ experience working in optics.
The importance of central corneal thickness measurements and decision ...
Measuring intraocular pressure (IOP) is well established, with the Goldmann Applanantion Tonometer (GAT) being the most widely used device. The influence of corneal thickness on IOP by conventional tonometers was acknowledged by Goldmann and clarified later by other investigators [2-6].
Why Pachymetry? Why Now? - Review of Optometry
Jan 20, 2003 · Measured IOP, or MIOP, refers to the actual reading that comes off the tonometer. True IOP, or TIOP, describes the actual intraocular pressure. Adjusted IOP, or AIOP, describes the tonometric measure factoring in corneal thickness.
Corneal thickness measurement: Pachymetry, a practitioner’s …
Central corneal thickness can be easily measured using a handheld ultrasound pachymeter. This article provides an overview of the methods of corneal pachymetry and the interpretation of the results.

Fix IOP according to central corneal thickness. IOP correction table used for adjusting intraocular pressure based on central corneal thickness (CCT). In order to adjust the IOP, just apply the correction factor on the right column to the intraocular pressure obtained by your tonometer.
Corneal Pachymetry - Measuring Corneal Thickness - Occuity
Glaucoma is a progressive optic neuropathy that can lead to blindness and one of its primary risk factors is high intraocular pressure (IOP). There are numerous studies that show a link between thinner corneas and a higher risk of developing glaucoma.
Measuring Up with Pachymetry | Optometric Management
Oct 1, 2004 · The reason for performing pachymetry is to establish a more realistic IOP based on a patient's corneal thickness. You may have two patients, each with pressures of 25 mmHg and similar disc changes.
Understanding Pachymetry: What You Need to Know
Apr 19, 2024 · Certain eye diseases, such as glaucoma, are associated with increased intraocular pressure (IOP). Measuring the corneal thickness helps in accurately assessing the IOP and determining the appropriate treatment plan.
