Corneal Thickness and Eye Pressure

Ask an Eye M.D. Answer Archive

Question:
How does the thickness of the cornea affect eye pressure? 

Answer:
The thickness of the cornea affects the instruments that ophthalmologists (Eye M.D.s) use to measure eye pressure. Although there are some algorithms that attempt to take this factor into account, unfortunately, at the moment, we still do not have a precise understanding of the impact of the thickness of the cornea on intraocular pressure. We can make generalized interpretations about the impact of corneas that are much thicker or much thinner than average. Therefore, for those more extreme cases, corneal thickness measurements may help a clinician better understand the dynamics of an eye.
