In an eye exam, what does "CCT" stand for?

The term "CCT" refers to Central Corneal Thickness. This measurement is critical in eye exams, especially for assessing the health of the cornea and diagnosing conditions such as glaucoma. The thickness of the cornea can influence intraocular pressure readings, and understanding this measurement helps eye care professionals make more informed decisions regarding treatment and monitoring of eye diseases. In clinical practice, measuring central corneal thickness is essential for evaluating the risk of glaucoma and planning potential surgical interventions.

The other options focus on different aspects of eye exams but do not accurately correspond to what "CCT" represents in this context. For instance, while corneal curvature is important in determining astigmatism, it is not what "CCT" stands for. The corrective cover test is used to assess binocular function and alignment of the eyes, and the comprehensive color test evaluates color vision but does not relate to corneal thickness. Thus, Central Corneal Thickness is the most relevant and correct interpretation of "CCT."
