Endothelial Cell Count

Endothelial Cell Count


The endothelium is the innermost layer of the cornea. The cells in this layer pump water out of the rest of the cornea so that it stays clear (rather than hazy and swollen). The number and appearance of the cells we have can be affected by a number of things, including age, injury, previous eye surgery, or certain eye disorders. It may be important for your ophthalmologist to get a count of the number of cells you have, and a closer visualization of what they look like.

The endothelial cell count (ECC) is the most accurate way of measuring the number of cells per square millimetre and their size/shape. It is used to help in the diagnosis of certain eye conditions, and also prior to surgery to assess the safety of the procedure given the health of your cornea.


You will be seated in front of a machine and instructed to look at a target. A picture will be taken of the front of your eye and sent to a computer for analysis. The test only lasts a few seconds.
