OCT Corneal Pachymetry
Pachymetry is a diagnostic test used in ophthalmology on a regular basis. Its objective is to measure the corneal thickness. The cornea is the layer of transparent tissue that covers the anterior area of the eye, and its usual tissue is between 500 and 600 microns in its central part, and between 600 and 800 in the peripheral area. The thickness of the cornea is a variable to consider during the diagnosis of diseases and for the realization of treatments.
Corneal pachymetry is very useful in ophthalmological diseases such as glaucoma, keratoconus, cornea guttata, corneal edema and in cases of patients who want to undergo corneal refractive surgery to correct myopia, astigmatism or hyperopia. For example in patients who suffer from glaucoma, corneal pachymetry is very important, because according to the corneal thickness we will apply a corrective factor to calculate the real intraocular pressure.
