CCT full form in medical is Central Corneal Thickness. Corneal thickness is an important measurement in the medical field, especially in ophthalmology because it can be used to identify how well the eye is able to focus light. A thinner cornea may cause the eye to focus light too strongly, resulting in nearsightedness, while a thicker cornea may cause the eye to focus light too weakly, resulting in farsightedness. Central corneal thickness (CCT) is a measure of the thickness of the cornea at its central point, which is the point that is directly in front of the pupil.
CCT is often used to help diagnose and monitor certain eye conditions, such as glaucoma and keratoconus. In the case of glaucoma, CCT is used to measure the thickness of the cornea and detect any changes that may be indicative of the condition. For keratoconus, CCT can be used to monitor the progression of the condition, since this eye disorder causes a thinning of the cornea. By measuring CCT, ophthalmologists can detect any changes in the cornea that may be indicative of an eye condition, and they can also monitor the progression of the condition over time.
