Pachymetry

Pachymetry is a simple painless test that quickly measures thickness of the cornea. The procedure can aid in the diagnosis of corneal thinning and is one of the investigations performed for diagnosis of glaucoma.It is also helpful to assess the functioning of corneal endothelium (back layer of cornea).Cornea is more likely to thin over time with onset of disease like keratoconus and glaucoma.
