What is the normal range for central corneal thickness measured by ultrasound?

The normal range for central corneal thickness measured by ultrasound is typically between 500 to 600 micrometers. This range is important because corneal thickness can influence the risk of developing eye conditions such as glaucoma and can affect surgical outcomes for procedures like LASIK. A corneal thickness within this range suggests healthy corneal structure and function, as well as an adequate level of hydration and cellularity in the corneal stroma.

The importance of measuring corneal thickness lies in its implications for overall ocular health; both excessively thin and thick corneas can indicate potential underlying issues that may require further investigation. By establishing a normal range of 500 to 600 micrometers, practitioners can better assess and monitor corneal health in patients during ophthalmic examinations.
