Intraocular Pressure Adjustment

Adjusting IOP Readings

Accurate measurement of intraocular pressure (IOP) is fundamental in diagnosing and managing glaucoma. However, the thickness of the cornea can significantly influence these measurements. Thicker corneas tend to yield higher IOP readings, potentially leading to an overestimation of glaucoma risk, while thinner corneas might result in underestimation. To address this variability, it is essential for optometrists to adjust IOP readings based on corneal thickness.

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.
