Evaluation of Corneal Oedema – Tools we Have and Those Under Investigation

European Ophthalmic Review, 2019;13(2):76–80 DOI: https://doi.org/10.17925/EOR.2019.13.2.76

Abstract

Corneal oedema is a common sign of acute or chronic corneal disease resulting from various aetiologies such as corneal endothelial dystrophy, prior surgery such as cataract surgery, metabolic disorders, toxicity or hypoxia. Measurement of central corneal thickness (CCT) is an objective and surrogate assessment for the evaluation of corneal oedema. The commonly used tools for the CCT measurements include ultrasonic pachymetry, anterior segment optical coherence tomography, specular microscopy and corneal tomography. Terahertz and mid-infrared technology have emerged recently for their applications on corneas. Instead of measuring CCT, they detect the changes of corneal water concentrations because their light wave spectrum is sensitive to water. The utility of these imaging systems as an adjuvant tool for the evaluation of corneal oedema, will be discussed in this article.
