The German oculist Burchard Mauchart provided an early description in a 1748 doctoral dissertation of a case of keratoconus, [18] which he called staphyloma diaphanum. However, it was not until 1854 that British physician John Nottingham (1801–1856) clearly described keratoconus and distinguished it from other ectasias of the cornea. [ 18 ]
Corneal pachymetry is the process of measuring the thickness of the cornea.A pachymeter is a medical device used to measure the thickness of the eye's cornea.It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery [1] and is useful in screening for patients suspected of developing glaucoma among other uses.
Used for neuro-ophthalmic conditions and general screening [5] as well as early detection of glaucoma [6] [7] 30-2: Measures 30 degrees temporally and nasally and tests 76 points. Used for general screening, early glaucoma and neurological conditions [6] The above tests can be performed in either SITA-Standard or SITA-Fast.

Keratoconus, a progressive, noninflammatory, bilateral, asymmetric disease, characterized by paraxial stromal thinning and weakening that leads to corneal surface distortion. [ 2 ] Keratoglobus , a rare noninflammatory corneal thinning disorder, characterised by generalised thinning and globular protrusion of the cornea.
Keratoconus in itself is a pattern of the entire cornea, therefore every measurement just focusing on one layer, might not be enough for a state of the art diagnosis. Especially early cases of keratoconus might be missed by a plain topographic measurement, which is critical if refractive surgery is being considered. [ 7 ]
